as long, strongly narrowed anteriorly from the acute basal 
angles; sides not margined, not explanate, slightly arcuate 
basally, more so anteriorly where rounded into front mar- 
gin; latter arcuate, almost lobed, at middle; base lobed 
before scutellum, broadly emarginate at sides; disk rather 
irregularly convex but without distinct impressions. Elytra 
ample, together 1/3 wider than prothorax, formed as in 
gracilis but surface even less distinctly impressed. Abdo- 
men ( $ ) with 6 ventral segments, 1st and 2nd not emar- 
ginate at middle. Mesosternum ( $ ) broader and less 
acutely impressed between middle coxae than in gracilis 
( $ ) . Front and middle tarsi ( $ ) slender, about as in 
Psephenus, without sexual papillae. Length not quite 4; 
width not quite 2 mm. 
Cuba: holotype $ (M. C. Z. no. 21,786) unique from 
Soledad, near Cienfuegos, Santa Clara, Nov. 2, 1926, taken 
by myself. I do not remember the circumstances of capture. 
Of the numerous characters which distinguish this species 
from gracilis as described, the different form of the pro- 
thorax (not subparallel near base in cubanus ) and the dif- 
ferent color and more regular pubescence may be presumed 
to be specific characters. The more densely roughened pro- 
notum, narrower labrum, and entire 1st and 2nd ventral 
segments of cubanus may prove to be either specific or 
sexual differences, probably the latter. The shorter, slightly 
differently formed antennse and palpi, the fewer ventral seg- 
ments, more widely separated middle coxse, and much 
smaller basal joint of front and middle tarsi, without 
papillae, are, by analogy with Psephenus, strictly sexual char- 
acters and are so treated in my generic description of 
Pheneps. 
Psephenops Grouvelle 
( Xexanchorinus Grouvelle) 
Notes from the Leyden Museum 20, 1898, pp. 44 & 45. 
The gentoype of Psephenops is P. smithi Grouv. All of 
the types of this species were $ $. Champion (Trans. Ent. 
Soc. London 1913, p. 63, PI. 3, figs. 2 & 2a) believed he 
had a $ Psephenops with dilated tarsi and 6 ventral seg- 
ments. However, Mr. K. G. Blair has kindly examined
