lateral margins, vaguely flattened at middle along anterior margin; 

 prehumeral carinae strongly elevated, sinuate, extending from base to 

 basal third, not united to marginal carinae; surface glabrous, finely, 

 densely granulose, finely, irregularly rugose on disk, finely, densely 

 punctate between rugae. Scutellum strongly, transversely carinate. 



Elytra broadly, arcuately constricted in front of middle ; tips sep- 

 arately, broadly rounded and finely dentate ; surface slightly flattened 

 on basal half, finely, densely scabrous, sparsely, uniformly clothed 

 with very short, recumbent, inconspicuous hairs. 



Abdomen narrowly exposed above, strongly convex beneath ; sur- 

 face obsoletely granulose, with fine crenulate lines on basal sternites, 

 sparsely clothed with short, recumbent, white hairs, with a longitu- 

 dinal, median row of long, dense, white hairs on first and second 

 sternites, and small patches of slightly denser, white hairs at sides 

 of fourth and fifth sternites ; suture between first and second sternites 

 obsolete. Prosternum finely, densely granulose, densely clothed with 

 moderately long, erect, white hairs ; prosternal lobe long, broadly sub- 

 truncate in front ; prosternal process broad, sides nearly parallel, apex 

 obliquely converging to an obtuse, median tooth. Tarsal claws dis- 

 similar on all feet ; anterior and middle pairs cleft near tips, the teeth 

 nearly equal in length and inner ones not turned inward; posterior 

 pair cleft near middle, the inner tooth shorter than the outer one. 



Female. — Unknown. 



Length 7 mm., width 1.6 mm. 



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



Type.— -U.S.N M. No. 56605. 



Remarks. — Described from the single male type collected December 

 25, 1941, by E. McC. Callan. 



This species is allied to Agrilus latifrons Waterhouse but differs 

 from that species in being of a different color, in having the front of 

 the head narrower, with the sides strongly converging anteriorly, and 

 not very deeply depressed at the middle, the surface of the pronotum 

 more finely rugose, the elytra more strongly acuminate posteriorly 

 and the surface more finely scabrous, and the abdominal sternites 

 without distinct pubescent spots at the lateral margins.
