NEW SPECIES OF AGRILUS FROM TRINIDAD — FISHER 379 



obliquely converging at apex to an acute median tooth. Tarsal claws 

 similar on all feet, cleft near middle, inner tooth of each slightly 

 shorter than outer one, turned inward touching the tooth of opposite 

 side. 



Female. — Differs from the male in having the front of the head black 

 and the pubescence on the prosternum shorter. 



Length 6 mm., width 1.3 mm. 



Type locality. — Talparo, Trinidad, British West Indies. 



Type, allotype, and paratype. — U.S.N.M. No. 56604. Paratypes 

 returned to Mr. Callan. 



Remarks. — Described from five specimens, two males and three 

 females (one male type), collected by E. McC. Callan. The type and 

 allotype were collected at the type locality, December 25, 1941, and 

 three paratypes were collected at Munclo Neuvo, Trinidad, April 4, 

 1943. 



This species is allied to AgrUus nignpennis Waterhouse but differs 

 from that species in having the front of the head wider and convex 

 and the pronotum without a deep depression in front of the scutellum 

 and without prehumeral carinae. 



AGRILUS TRINIDADENSIS, new species 



Male. — Elongate, rather slender, subcylindrical, feebly shining; head 

 greenish black on front, becoming brownish black on occiput ; pronotum 

 and scutellum brownish black; elytra greenish black; underside of 

 body black, with a faint bronzy-green reflection. 



Head with front rather narrow, distinctly wider at top than at bot- 

 tom, with a broad, longitudinal, median depression extending from oc- 

 ciput to clypeus; sides parallel along occiput and vertex, strongly, 

 obliquely converging from vertex to bottom; surface densely granu- 

 lose, coarsely, shallowly, and confluently punctate, clothed with a few 

 short, semierect, inconspicuous, white hairs along sides and behind 

 clypeus; clypeus narrow between antennae, deeply, arcuately emar- 

 ginate in front. Antenna extending to apical third of pronotum, ser- 

 rate from fourth segment. 



Pronotum distinctly wider than long, wider at apex than at base, 

 widest near apex ; sides nearly parallel along apical half, then arcuately 

 converging to near posterior angles, which are rectangular and slightly 

 projecting outward ; marginal and submarginal carinae slightly sinu- 

 ate, widely separated anteriorly, the submarginal carina not connected 

 with the marginal carina, and obsolete behind middle ; anterior margin 

 slightly sinuate, median lobe slightly produced and broadly rounded ; 

 base arcuately emarginate on each side, median lobe slightly produced, 

 and broadly truncate in front of scutellum ; disk rather deeply, broadly 

 depressed in front of scutellum, very broadly, deeply depressed along
