Two new species, Colon (Myloechus) koreanus new species (type locality—Mt. Odaesan, Pyeongchang-gun, Gangwon Prov., Korea) and C. (M.) shini new species (type locality—Mt. Odaesan, Pyeongchang-gun, Gangwon Prov., Korea), of the genus Colon Herbst are described from Korea and Japan. Types and paratypes of the new species are designated. The subfamily Coloninae and the genus Colon are reported for the first time in Korea. Colon (Myloechus) shini is the eighth species recorded from Japan. A key to the species of Colon in Korea and Japan, and illustrations of diagnostic features of the two new species are presented.

Herein are presented new state distribution records for 49 species of Cerambycidae from Mexico. New country records are provided for Enaphalodes seminitidus (Horn in Leng), Mephritus apicatus (Linsley), Rhopalophora nigriventris Bates, Psapharochrus arietis (Bates), Steirastoma liturata Bates, Nyssodrysternum pictulum Bates, and N. poriferum (Bates).

A new species, Poophylax villosa, previously noted from subfossil deposits but not formally described, is described and illustrated from the Falkland Islands. Poophylax falklandica Champion, the type species of the formerly monotypic genus Poophylax, is re-examined and compared with the new species. Distinguishing features are given. Poophylax falklandica is recorded from South America for the first time.

Bunites Spangler has been the only member of the tribe Colymbetini for which the larva has been unknown. The first-instar larva of Bunites distigma (Brullé) is described and figured for the first time. Detailed morphometric and chaetotaxic analyses are provided. A phylogenetic analysis based on 41 first-instar larval characters, including members of six genera of Colymbetini, supports the hypothesis of a derived condition of Bunites within this tribe. Monophyly of Bunites Rhantus Dejean (s. lat.) (minus Rhantus orbignyi Balke) Neoscutopterus J. Balfour-Browne Meladema Laporte is suggested by four synapomorphies: an elongate and hair-like seta FE5 on both meso- and metafemur, and the presence of additional anteroventral setae on tibia and tarsus. The clade Bunites Neoscutopterus Meladema is supported by three synapomorphies: the presence of additional setae on the frontoclypeus, dorsal surface of parietal, and urogomphi. Six other character states might also support this group. The clade Bunites Meladema is well supported by four synapomorphies: the presence of additional setae on the lateromedial portion of frontoclypeus, ventral surface of parietal, anterodistal margin of prementum, and anterodorsal surface of tibia. A derived condition of Bunites within the Colymbetini is suggested by two autapomorphies: the presence of one additional seta on the coxa, and additional dorsal pores on the eighth abdominal segment.

The results of this study indicate the historic range of Cicindela hirticollis abrupta Casey was limited to only five sites within the Sacramento Valley of California. Extensive searches within and beyond its historic range along the Feather and Sacramento Rivers in 2001–2004 failed to find any individuals of this tiger beetle and very little suitable habitat. Another tiger beetle, C. o. oregona Dejean, which occurs in a much greater array of water edge habitats, was common at some sites. The cumulative effects from the Oroville and Shasta Dams, including loss and deterioration of sandy edge river habitats and prolonged high water levels, probably caused the extirpation of C. h. abrupta in the late 1980's to early 1990's.

Catogenus inbio Ivie and Ślipiński new species is described from Costa Rica. It is illustrated, and incorporated into existing keys. Catogenus rufus (Fabricius), C. castaneus (Perty), Taphroscelidia rostrata (Sharp) and Passandra fasciata (Gray in Griffith) are recorded from Costa Rica for the first time.

The total network of Finnish forest roads has increased from a few hundred km in 1950 to currently over 120,000 km, but the ecological consequences of that process on invertebrates are poorly understood. I pitfall-trapped carabid beetles (Coleoptera: Carabidae) at roadsides and in adjacent forests along six forest roads in Finland. I carried out two studies on whether roads function as obstacles to the movement of forest carabids, or dispersal corridors for generalist and open-habitat species. In addition to these two studies, I compiled carabid observations from national entomologists to get an overview on carabid richness and on life-history traits associated with roadside carabids. A forest carabid Calathus micropterus (Duftschmid) was less abundant on the roadsides, compared to the adjacent forests. However, species richness and the abundance of a habitat generalist Pterostichus niger (Schaller) showed the opposite, and open-habitat species were solely caught on the roadsides. At the roadsides, generalists decreased in abundance with increasing distance to the nearest large open-habitat area along the road. This result may indicate that roadsides are dispersal corridors and/or “sink” habitat for these carabids. I did not detect such a trend for open-habitat species, which may indicate that roadsides are habitats, not just dispersal corridors for these carabids. Multivariate Regression Trees showed that the roadside and forest carabid assemblages were different. Forest type played a key role in shaping carabid assemblages of forests, whereas roadside carabid assemblages were mostly affected by factors related to lighting conditions (road width, proximity of open habitat, and compass direction). I caught several forest carabids between the ruts of forest roads, indicating that these beetles frequently cross forest roads. The 97 carabid species found by Finnish entomologists from different kinds of roadsides, reported here, indicate that roadsides host rich carabid assemblages of relatively common species mostly associated with open and man-made habitats.

Apphianus yuccae, new genus and new species in the tribe Attagenini, subfamily Anthreninae, family Dermestidae is described from a Mojave Desert canyon on the eastern edge of the Sierra Nevada in Kern Co, California.

A new apionine weevil, Coelocephalapion gandolfoi, new species, from Argentina and Chile is described and illustrated. The new species belongs to the C. frontellum species group and is especially close to the North American species C. frontellum (Fall), C. subornatum (Fall) and C. tellum Kissinger. Coelocephalapion gandolfoi has been associated with the pods or plants of the following species of Prosopis L. (Fabaceae): P. alba (Grisebach), P. alpataco Philippi, P. caldenia Burkart, P. chilensis (Molina), P. flexuosa DC, P. nigra (Grisebach), and P. ruscifolia (Grisebach). It is under investigation as a potential biocontrol agent for invasive Prosopis species in South Africa.

Third to sixth instar larvae of the aquatic firefly Luciola substriata swim with their ventral side up, including when they were searching for prey. When larvae were engaged in swimming, the thoracic legs sculled backwards continuously, while the abdomen could curve upward and downwards. The pygopodium located in the end of abdomen enable larvae to grasp and adhere on floating objects that also help start or cease swimming. When larvae in back-swimming changed direction, the larval abdomen curved clockwise or counterclockwise quickly and then unbent. The legs movement of larvae consists of eight different stroke patterns. The larvae averaged 1.6 strokes per sec and 0.6 wiggle of abdomen per sec. Larvae swim slowly with the speed of 0.9 m/h.

Species in the genus Onycholabis Bates are briefly reviewed and a new species from western Yunnan Province, China is described: Onycholabis stenothorax new species (Type locality: Yunnan, Tengchong, Qushi, Xiangyang Bridge, 25°12′38.4″N/98°34′49.4″E, 1,515 m). Nomenclatural changes proposed include the following: Onycholabis vietnamicus Kasahara and Onycholabis uenoi Paik and Lafer are recognized as junior synonyms of Onycholabis sinensis Bates new synonymies; Onycholabis sinensis nakanei Kasahara is recognized as a distinct species, O. nakanei Kasahara new status; and two species, Onycholabis luzonensis Jedlička and Onycholabis macrops Louwerens are removed from Onycholabis and tentatively transferred to Notagonum Darlington—Notagonum luzonensis (Jedlička) new combination and Notagonum macrops (Louwerens) new combination.

A key to adults of all six known species of Onycholabis is provided.

The morphology and life history of Mylabris phalerata Pallas (Coleoptera: Meloidae) were observed. The effect of temperature on the duration of immature stages of M. phalerata reared at 18, 22, 25, 28, 31, and 34°C was determined. The adaptable temperature for artificial mass rearing was ≥28°C. Lower developmental thresholds were estimated to be 6.38, 6.29, 7.72, 7.08, 5.25, 17.62, and 5.58°C for egg, larval instars L1, L2, L3, L4, L5 and pupa, respectively, and the thermal constant was 1,715.59 degree-days for total immature stages, using the linear model. Based on the developmental cycle of M. phalerata, its known geographic distribution, and temperature data, diapause is attributed to the overwintering fifth-instar larva.
