[June 
near basal angles, base finely and inconspicuously wrinkled, 
not obviously punctate. Elytra finely striate, striae not dis- 
tinctly punctate except for minute serial punctures on 
second, fifth, and seventh; scutellar stria rather long; in- 
tervals flat, alutaceous, but without evident punctuation; 
humeri distinct ; subapical sinuation of margin slight. Pos- 
terior tarsi long. Prosternum not margined at apex. Male 
with front tarsi rather narrow; first joint longer but not 
wider than second, spinulose but not squamulose beneath; 
joints two to four distinctly but narrowly squamulose; 
middle tarsi almost without sexual clothing; hind tibiae 
straight ; middle tibiae nearly straight, only slightly arcuate. 
Length 11 14 mm. 
Haiti: holotype $ (Museum of Comparative Zoology no. 
19526) from Cap Haitien, W. M. Mann; 3 paratypes 
( $ 9 $ ) from Jean Rabel, Feb., E. C. & G. M. Leonard 
(United States National Museum) ; 1 $ paratype from 
Port-au-Prince, Aug., G. N. Wolcott (U. S. N. M.) . 
The outstanding structural characters of this Seleno- 
phorus are the deep emargination of the labrum, deeper 
than in any other species I have seen, and the reduced 
squamulation of the male tarsi. The emargination of the 
labrum is said by Putzeys (Ent. Zeit. Stettiner 1878, Vol. 
39, p. 4) to be variable in this genus and to reach its great- 
est development in S. batesi Putz., which is otherwise quite 
different from the present species. Bates, in “Biologia” (p. 
274), under S. hepburni, comments on the reduction of the 
squammules of the male tarsi in some Selenophorus. He 
found the character usually associated with arcuation of the 
male middle tibiae, but in the present species the tibiae are no 
more arcuate than in S. chalybeus Dej. The new species 
probably has a superficial resemblence to anceps Putz. and 
opacus Putz., of the Argentine and Brazil respectively, and 
to one or two other species, but differs, to judge from des- 
criptions, not only in minor details but in having the la- 
brum much more emarginate. It is a rather atypical Selen- 
ophorus, but cannot be referred to any other genus at pres- 
ent described.
