Psyche 
[June-Sept. 
tarsi with 1st and especially 2nd joints elongate, lobed, and 
with hairy soles. Length 2y % ; width 1 1/3 mm. 
Colombia: holotype 8 (M. C. Z. no. 21,788) unique from 
Rio Frio, about 20 mi. south of Santa Marta, Prov. of Mag- 
dalena, Feb. 25, 1928, taken on a stone in the Rio Frio 
River. 
Differs from Psephenops smithi Grouvelle and Ps. grou- 
vellei Champion (1. c .) in color and in having the sides of 
the prothorax strongly rounded near the base. The poste- 
rior tarsi are like those of grouvellei as figured by Cham- 
pion. 
4. Psephenops haitianus n. sp. (PL III, figs. 2 & 3) 
Psephenus-like, rather depressed; dark brown, bases of 
legs, parts of lower surface, and base of elytra pale, pale 
area extending back (vaguely) on each elytron in a triangle 
1/3 of length; upper surface roughened, especially on pro- 
notum of 9 , not distinctly punctate, with fine, short, uni- 
form, subdecumbent pubescence. Head small, just over V 2 
( 8 ) or less than V 2 (?) width prothorax ; eyes prominent ; 
front faintly concave; clypeus wide, short, free at ends; 
labrum' narrower ; antennae moderate, reaching well ( 8 ) or 
slightly ( $ ) beyond basal angles of prothorax, first 2 joints 
rather stout, 2nd about V 2 length 1st, 3rd i/2 longer than 
2nd, outer joints progressively slightly shorter. Prothorax 
transverse, over 2 ( 8 ) to about 2 V 2 (?) times wide as 
long; much narrowed anteriorly; sides not margined, not 
explanate, slightly and evenly arcuate ( 8 ) or sinuate be- 
fore the posterior angles ( ? ) ; latter acute ; anterior angles 
very obtuse; base broadly lobed before scutellum, emargi- 
nate at sides ; apex nearly truncate ; disk convex, faintly de- 
pressed before posterior angles, very obsoletely carinate at 
middle of base. Elytra ample, together about 1/3 ( 8 ) to V 2 
( $ ) wider than prothorax ; sides nearly straight and slightly 
divergent basally, broadly rounded to the independently 
rounded apices; surface with faint, longitudinal, stria-like 
impressions, more distinct in $ , in which alternate intervals 
are slightly elevated near suture. Length (3 9 ) about 2% 
& 3!/2 ; width 1 2/5 & 2 1/10 mm. (exact measurement diffi- 
cult because of position of specimens).
