Psyche 
[September-December 
The only other species presently recognized in the genus is A. 
egenus LeConte, distributed from Ontario to North Carolina 
(Brown, 1937). The presence of the following four new species in 
Jamaica and Puerto Rico strengthens Brown’s suspicion that Cyr- 
tusa conicitarsus Champion (1925) of St. Vincent in the Lesser 
Antilles is actually an Apheloplastus . We may also expect that 
other species described as Cyrtusa belong in Apheloplastus. In this 
context, Brown mentions species from New Zealand and Europe. 
The many species of Cyrtusa described in the past two decades by 
Hlisnikowski should also be reexamined with this in mind. 
All members of the genus probably feed on fungi in decompos- 
ing forest litter. All specimens reported on in this paper were taken 
in litter Berlese samples only.

Diagnosis. The species is distinguished by its restriction to Ja- 
maica, its large eye size, functional flight wings, relatively uniform 
brown color, shape of male femora and tibiae, and aedeagus. 
Description. Length 0.9-1. 4 mm, width 0.7 to 0.9 mm. Color 
uniformly light to medium dark yellowish brown. Eye large (fig. 4), 
as wide as long. Head and pronotum lightly punctured, elytra with 
nine rows of punctate striae, the ninth marginal. Metasternum 
strongly punctured. Flight wings fully developed. Male meso- 
femur with partially serrated hind margin, mesotibia with many 
strong spines (fig. 1). Male metafemur with pronounced apical 
tooth (fig. 2). Aedeagus (fig. 6) with broad lobes at tip, parameres 
almost as long as median piece.
