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. Ad- 
ditional 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 Mu- 
seum (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 Dissochaetus jamaieensis, 460 specimens of Aglyptinus puerto- 
ricensis, 10 specimens of Aglyptinus jamaieensis, 1032 specimens 
of Aglyptinus dimorphicus, and on four new species of Aphelo-
