the following three joints united ; tarsal claws bifid or dentate. Body 

 elongate, feebly convex, broadly rounded in front, and acuminate 

 behind. 



This is a very large genus containing over 1,000 described species 

 which are distributed throughout the entire world, with the exception 

 of the extreme northern parts. The species of this genus seem to be 

 rare in the West Indies, as only two have been described from that 

 region, and the specimens are extremely rare in collections. 



AGRILUS DOMINICANUS Thomson 



Agrilus dominicanus Thomson, Typi Buprestidarum, 1878, pp. 88-89. 



Elongate, rather robust, broadly rounded in front, strongly attenu- 

 ate behind, and distinctly wider in front than behind, olivaceous- 

 green, with cupreous and purplish reflections in certain lights, the 

 cupreous tinge more pronounced on the head and pronotum; be- 

 neath aeneous, with a strong purplish tinge. 



Head broadly but not very deeply concave, the concavity deeper 

 and narrower on the vertex, becoming broader on the front and ex- 

 tending to the epistoma and transversely to the margin of the eyes, 

 the margins parallel on the front and strongly constricted on the ver- 

 tex; surface coarsely, irregularly rugose, becoming coarsely punctate 

 on the occiput, with a narrow smooth carina along the margin of the 

 eyes, rather densely clothed with moderately long, wide, recumbent 

 fulvous hairs, having a tendency of forming denser spots on the 

 front; intervals finely and densely granulose; epistoma wider than 

 long, about two times as wide as the antennal cavities, separated from 

 the front by a transverse arcuate carina, deeply and broadly arcu- 

 ately emarginate in front, with the surface finely granulose; eyes 

 feebly reniform, moderately convex, and two times as long as wide. 

 Antennae extending to about the middle of pronotum, and serrate 

 from the fourth joint. Pronotum rather evenly convex, one and one- 

 third times as wide as long, about equal in width at base and apex, 

 slightly narrower at basal fifth; sides nearly parallel, with a feeble 

 sinuation near the base, and not explanate; lateral marginal edge 

 sinuate when viewed from the side, and the two margins uniting 

 near basal third; anterior margin arcuately emarginate, with a 

 broadly rounded median lobe; base truncate to elytral lobe, then 

 abruptly emarginate and turning obliquely backward to the scutel- 

 lum, in front of which it is broadly truncate; posterior angles rec- 

 tangular, with a rather broad, strongly sinuate carina extending to 

 the apical angles ; surface with a broad, moderately deep longitudinal 

 median impression extending from the anterior margin to scutellum, 

 and on the inner side of the lateral carina, a very sinuate impression 

 extending from base to the anterior margin, the surface is also 

 coarsely, transversely, and irregularly strigose; intervals finely and 

 densely granulose, with a few fine punctures along the strigae, the
