Pronotum quadrate, subequal in width at base and apex, widest along 

 apical half; sides nearly parallel anteriorly, slightly converging pos- 

 teriorly ; posterior angles acute, slightly projecting outward ; marginal 

 and submarginal carinae slightly sinuate, widely separated anteriorly, 

 united near base; anterior margin strongly sinuate, median lobe 

 strongly produced and broadly rounded ; base arcuately emarginate on 

 each side, median lobe slightly produced, broadly subtruncate in front 

 of scutellum; disk broadly, shallowly, transversely depressed along 

 base, broadly depressed along lateral margins, vaguely, transversely 

 flattened at middle near anterior margin, but without longitudinal, 

 median depressions; prehumeral carinae strongly elevated, arcuate, 

 united to marginal carinae at middle ; surface nearly glabrous, coarsely, 

 deeply, transversely rugose on disk, indistinctly punctate between 

 rugae. Scutellum strongly, transversely carinate. 



Elytra, broadly, shallowly constricted in front of middle ; tips sepa- 

 rately broadly rounded, coarsely dentate, median tooth on each 

 slightly longer than other teeth; surface vaguely depressed along 

 sutural margins, densely, finely imbricate-punctate, each elytron 

 ornamented with three small, white, pubescent spots, one in basal de- 

 pression, one in front of middle, and one behind middle, and with a 

 few white hairs along sutural margin near apex. 



Abdomen narrowly exposed above, strongly convex beneath ; surface 

 densely, finely granulose, indistinctly punctate, nearly glabrous on 

 median part, with sparse white pubescent spots at sides of first, third, 

 fourth, and fifth sternites and on vertical portion of second sternite ; 

 suture obsolete between first and second sternites, the first sternite 

 flattened at middle. Prosternum densely granulose, sparsely clothed 

 Avith short, semierect, inconspicuous, white hairs; prosternal lobe long, 

 broadly rounded in front ; prosternal process broad, parallel at sides, 

 truncate, with an obtuse median tooth at apex. Tarsal claws similar 

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

 than outer one, turned inward, but not touching tooth on opposite 

 side. 



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

 coppery and more feebly converging anteriorly, and the first ab- 

 dominal sternite convex at the middle. 



Length 6 mm., width 1.4 mm. 



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



Type and allotype. — U.S.N.M. No. 56C02. Paratype returned to

Remarks. — Described from three specimens (one male type), all 

 collected at the type locality, December 25, 1941, by E. McC. Callan. 



This species is allied to Agrilus fallax Say but differs from that 

 species in being slenderer and more strongly acuminate posteriorly, in
