West Indian Dryopidse 
67 
substriate ; antennae slightly longer, heavier, and more 
nearly serrate; maxillary palpi longer, heavier, with last 
joint more triangular; front and middle tarsi not dilated 
but with soles first 2 joints with numerous rather short, 
slender papillae; middle coxae much more approximate, 
mesosternum between them narrower and more acutely 
impressed; abdomen with 7 ventral segments (6th showing 
only at sides of 7th, in emargination of apex of 5th), not 
6 as in 9 . 
Pheneps n. gen. 
Generally similar to Psephenus, but more slender; head 
free; coxae similar; last tarsal joint elongate, but not quite 
so much as in Psephenus ; epipleurae similar, nearly reaching 
apex of elytra; sexual dimorphism of palpi, mesosternum, 
and apical segments of abdomen similar. Differs from 
Psephenus in clypeus and labrum nearly in plane of front, 
not bent under head ; in very long antennae reaching to near 
middle of elytra at least in $ , with 1st joint long, slightly 
bent, slightly thickened, 2nd less than % as long, slightly 
thickened, 3rd about length of 1st, but more slender, about 
4 times long as wide in 8 , outer joints gradually shorter, 
subserrate at least in 8 ; differs also in sides of prothorax 
not explanate, and in basal joint front and middle tarsi 8 
enlarged as well as with papillae, broadly oval, several times 
bulk of 2nd joint, deeply emarginate apically. Differs 
from Psephenops in very elongate antennae and in 2d joint 
8 tarsi small, though with sexual papillae as in Psephenus. 
The genotype is 
1. Pheneps gracilis n. sp. (PI. Ill, fig. 5) 
Male only. Moderately slender, depressed; dark grayish 
brown, mouth, bases of legs, last (sometimes) and apices 
of some or all other ventral abdominal segments testaceous ; 
upper surface finely and very inconspicuously punctate, 
with fine, short, more or less decumbent gray pubescence, 
the direction of which varies on the elytra to form an irreg- 
ular, variable, sericeous pattern in some lights. Head not 
quite 3/5 width prothorax; eyes large and prominent; 
clypeus very wide, short, free at sides; labrum equally
