A small collection of Psocoptera based on a rapid survey of the Ragged Islands group of the Bahamas contains 14 species in eight families. Six species are new and are described in the following genera: Echmepteryx (one), Cerobasis (one), Blaste (one), Indiopsocus (three). Pseudocaecilius similis Turner, described from Jamaica, is a new junior synonym of Pseudocaecilius tahitiensis (Karny).

This is the second part of the taxonomic studies on Palaearctic Tettigoniidae carried out in some European and Turkish collections. Sixty species and subspecies collected from Turkey and the Middle East countries are given. The genera Farsodecticus Mirzayans and Zagrosiella Mirzayans are studied and discussed for the first time after their descriptions. Farsodecticus is included to the tribe Tettigoniini. Known species of Mixodusa Stolyarov are compared using both sexes. Anterastes uludaghensis species group is reviewed. Three species of Uvarovistia Maran are given with comparable new illustrations. The genus Koroglus Ünal is validated with a discussion and comparison to the A. uludaghensis sp. group. Two new species, Lithodusa mirzayani sp.n. from Iran, Platycleis (s.str.) kibris sp.n. from Cyprus are described. A lectotype for Eupholidoptera smyrnensis (Brunner, 1882) is designated. Two species are synonymized: Anterastes ucari Çiplak, 2004 with A. babadaghi Uvarov, 1939 and Eupholidoptera femorata Çiplak, 1999 with E. unimacula Karabağ, 1956. Besides, the priority of the paper of Schulthess-Rechberg (1882) and the book of Brunner von Wattenwyl (1882) is discussed and the precedence is given to Schulthess-Rechberg. Therefore, Brunner's taxa Anterastes serbicus Brunner, 1882 and Metrioptera (Broughtonia) domogledi (Brunner, 1882) are synonymized with Anterastes serbicus (Schulthess-Rechberg, 1882) and Metrioptera (Broughtonia) domogleti (Schulthess-Rechberg, 1882) respectively and currently synonyms two more taxa described by Schulthess are discussed under the account of A. serbicus in the text. The authorship of the tribes Pholidopterini and Platycleidini is discussed. Keys to the species of Lithodusa Bey-Bienko, 1951, Uvarovistia Maran, 1953 and A. uludaghensis sp. group are prepared. Besides, many taxonomic, systematic and faunistic discussions for the taxa are given. To support the descriptions and discussions 152 figures are provided.

The invertebrate fauna of the Mississippi River is compiled from published material (215 total taxa) is compiled from published material (205 taxa) and records of 10 new taxa obtained in a dietary study of sturgeon in the Lower Mississippi River. The previously undocumented taxa are Leptophlebia sp. (Ephemeroptera: Leptophlebiidae), Pseudiron centralis McDunnough (Ephemeroptera: Pseudironidae), Gillotia sp. (Diptera: Chironomidae), Lipiniella sp. (Diptera: Chironomidae), Metriocnemus fuscipes (Meigen) (Diptera: Chironomidae), Parachironomus sp. (Diptera: Chironomidae), Paratendipes basidens Townes (Diptera: Chironomidae), Polypedilum flavum (Johannsen) (Diptera: Chironomidae), Saetheria sp. (Diptera: Chironomidae), and Zavrelia sp. (Diptera: Chironomidae).

Seventy six new Melanoplus species from the United States are described. These include the following groups and species:
