Type locality— Talparo, Trinidad, British West Indies. 



7'ype — U.S.N.M. No. 56603. Paratype returned to Mr. Calkin. 



Remarks. — Described from two females (one type) collected at the 

 type locality, December 25, 1941, by E. McC. Callan. 



This species resembles Agrilus infidelis Fisher but differs from that 

 species in having the antenna serrate from the fourth segment and 

 in not having prehumeral carinae on the pronotum or pubescent spots 

 on the elytra. 



AGRILUS PICINUS, new species 



Male.— Elongate, slender, subcylindrical, strongly shining, glabrous 

 on dorsal surface; uniformly brownish black, with a slight greenish 

 tinge on underside of body, and the head green in front, becoming 

 brownish on occiput. 



Head with front broad, wider at top than at bottom, with a vague, 

 longitudinal, median depression on vertex; sides feebly converging 

 from top to bottom ; surface densely, finely granulose, sparsely, finely 

 punctate, clothed with a few short, white hairs near clypeus ; clypeus 

 narrow between antennae, deeply, arcuately emarginate in front ; an- 

 tenna short, extending slightly beyond apex of pronotum, serrate from 

 fourth segment. 



Pronotum slightly wider than long, subequal in width at base and 

 apex, widest near apex; sides nearly parallel anteriorly, obliquely 

 converging posteriorly; posterior angles rectangular; marginal and 

 submarginal carinae sinuate, widely separated anteriorly, united be- 

 hind middle, the submarginal carina obsolete near apex ; anterior mar- 

 gin strongly sinuate, median lobe strongly produced and broadly 

 rounded; base angularly emarginate on each side, median lobe broadly 

 subtruncate in front of scutellum; disk broadly, transversely flattened 

 along base, deeply depressed at middle along lateral margins, vaguely 

 flattened at middle in front of middle, but without distinct longi- 

 tudinal, median depressions and prehumeral carinae; surface finely, 

 shallowly, transversely rugose on disk, finely granulose and indistinctly 

 punctate between rugae. Scutellum strongly, transversely carinate. 



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

 arately broadly rounded and very finely dentate; surface flattened on 

 basal half, longitudinally depressed along sutural margins on apical 

 half, densely, finely granulose, densely, coarsely imbricate-punctate. 



Abdomen broadly exposed above, strongly convex beneath; surface 

 indistinctly granulose, with fine, transverse, crenulate lines, which are 

 more distinct on basal sternites, very sparsely clothed with short, re- 

 cumbent, white hairs; suture between first and second sternites obsolete. 

 Presternum densely, coarsely scabrous, densely clothed with short, 

 erect, white hairs ; prosternal lobe long, subtruncate or vaguely, broadly 

 emarginate in front; prosternal process broad, sides nearly parallel,
