Seven new Neotropical deltocephaline leafhopper genera are described and illustrated: Hecadula (Cicadulini); Stenogrampta, Penthigrampta, and Perugramptella (Penthimiini); and Chimaerotettix and Idioceromimus (incertae cedis). Together these genera are based on 11 new species from Ecuador, Peru, and Brazil, including ten from rainforest canopy-fogging samples. Male, female, and (for four genera) fifth-instar characters are described and illustrated. Perugrampta Kramer is redescribed and transferred from Nirvaninae to Penthimiini, together with four new species, and a key to the six known species is provided. This and the three new penthimiine genera apparently represent an endemic Neotropical clade distinct from the Old World Penthimiini. Hecadula is the only known endemic South American representative of the largely Holarctic tribe Cicadulini. Chimaerotettix and Idioceromimus display unusual combinations of deltocephaline and non-deltocephaline traits and, thus, may represent endemic South American deltocephaline lineages distinct from currently recognized tribes.

Two new monotypic genera of stactobine microcaddisflies (Trichoptera: Hydroptilidae), Orinocotrichia, and Tizatetrichia are described and illustrated from Venezuela and Costa Rica, respectively. Keys are provided for males and females of the New World genera comprising the tribe Stactobiini.

The Neotropical genus Flintiella is reviewed and eight new species are described and illustrated: F. alajuela from Costa Rica, F. boraceia from Brazil, F. panamensis from Panama, F. tamaulipasa from Mexico, F. yanamona from Peru, F. heredia from Costa Rica, Ecuador, and Peru, F. astilla from Brazil, Costa Rica, Ecuador, Paraguay, Peru, and Venezuela, and F. pizotensis from Columbia, Costa Rica, Ecuador, Mexico, Panama, and Peru. New illustrations are provided for F. andreae Angrisano. Keys are provided to separate the males and the associated females of the nine known species in the genus.

A new species, Cerceris escalante, is described from Kane and Garfield counties, Utah.

Trichesthes Erichson, 1847 is currently a synonym of Phyllophaga (s. lato), but its taxonomic status merits review. Based on a phylogenetic analysis of external morphological and genitalic characters, Trichesthes is revalidated as a monophyletic genus that includes two of the nine species originally placed in Trichesthes, as well as 38 other species currently classified in the Phyllophaga subgenera Phytalus, Listrochelus and Phyllophaga (s. str.).

The immature stages of the flea beetle Alagoasa januaria Bechyné (Coleoptera: Chrysomelidae: Galerucinae) are described and illustrated. Terminal addition of setae in later instars is present. The life history of Alagoasa januaria is discussed. Alagoasa januaria feed on Stachytarpheta cayennesis (Rich.) Vahl (Verbenaceae). Differences between these and other known Oedionychina immatures are discussed.

Resumen.—Se describen e ilustran las fases inmaduras (huevo, larva y pupa) del escarabajo Alagoasa januaria Bechyné (Coleoptera: Chrysomelidae: Galerucinae). En el segundo estadio larval aparecen cerdas. Se discute la historia natural del Alagoasa januaria. El Alagoasa januaria se alimenta de Stachytarpheta cayennesis (Rich.) Vahl (Verbenaceae). Se discuten las diferencias entre el Alagoasa januaria y otros Oedionychina inmaduros conocidos.

Carabid beetle communities were compared for adjacent marsh and bog biotopes at the McLean Bogs Preserve, Tompkins Co., New York by means of pitfall-trap sampling. Though the sampled marsh and bog habitats were only 200 m distant, with the umbrotrophic bog isolated from the marsh/fen complex by a Wisconsin-aged glacial esker of only 7 m elevation, the resident wetland carabid species assemblages differed significantly between the sites during the spring and summer seasons. Of 62 species observed in the wetlands, 36 were found exclusively in the marsh biotope, 17 were exclusive to the bog site, and only 9 were found at both sites. This level of wetland habitat fidelity was maintained in spite of potential colonization of the two sites each spring by adult beetles dispersing from overwintering sites in surrounding forest edge habitats. Pitfall sampling found 59 native carabid species, of which 52 were found during a survey conducted from 1916–1925, suggesting that the McLean Bogs Preserve supports locally resident populations for the vast majority of carabid species found during this study. The McLean Bogs Preserve supports geographically southern, peripheral populations of the bog-specialist Platynus mannerheimii Dejean, as well as four marsh/fen-inhabiting species—Trechus crassiscapus Lindroth, Bembidion muscicola Hayward, B. praticola Lindroth, and Bradycellus semipubescens Lindroth—emphasizing the role this preserve plays in maintaining the distributional ranges of both bog- and marsh-resident taxa. The distinct faunas observed in these two proximate biotopes clearly illustrate that comprehensive conservation of the carabid beetle fauna of northeastern North America should involve preservation of a variety of wetland types.
