New Records and Species of Leiodinae and Catopinae (Coleoptera:Leiodidae) From Jamaica and Puerto Rico, With a Discussion of WingDimorphism

Since my earlier reports on the Leiodidae of Jamaica and Puerto Rico (Peck, 1970, 1972), I have had the opportunity to spend an additional 13 weeks in field work on these islands. In Jamaica this was from mid-December to mid-January, 1972-1973, and from late July to early September, 1974. In Puerto Rico it was from early to late May, 1973, and a week in June, 1974. This has resulted in new data on the leiodids of these islands, which are presented here. Additional data and information on forest habitat sites may be found in Peck and Kukalova-Peck (1975), and on cave sites in Peck (1974, 1975). Methods and materials are similar to those utilized for my earlier papers. Collections were primarily made in forests with pitfall traps baited with carrion and human dung (Newton and Peck, 1975); by Berlese-Tullgren funnel extraction of arthropods from sifted forest litter, and from bat guano accumulations in caves. In this work, 259 kg (770 liters) of sifted forest litter were processed for Jamaica and 93 kg (171 liters) for Puerto Rico, in addition to many other extractions from samples of bat guano. Most of the arthropod residues from these collections are deposited with the Field Museum (Chicago). Some beetles are deposited in the Museum of Comparative Zoology (Harvard University), and the Canadian National Collection of Insects (Agriculture Canada, Ottawa). In this paper I report only on new collections of 393 specimens of Dissoehaetus jamaicensis, 460 specimens of Aglyptinus puertoricensis, 10 specimens of Aglyptinus jamaicensis, 1032 specimens of Aglyptinus dimorphicus, and on four new species of Aphelo-
