ART. 9 WEST INDIAN BUPRESTIDAE FISHER 161 



classification, this genus slioiild not be included in the tribe Chal- 

 cophorini as the antennal pores are placed on the lower anterior 

 margin of the joints, but should be placed in the tribe Buprestini 

 near the genus Peronaemis Waterhouse, to which it is closely allied. 



MIXOCHLORUS ELEGANS, new species 



Agriliform, broadly rounded in front and strongly acuminate 

 behind, shining and nearly glabrous; head green, with a large tri- 

 angular reddish-cupreous spot on the occiput, the spot divided longi- 

 tudinally by a narrow green line; pronotum and elytra reddish- 

 cupreous, the former with the lateral margins, sides of the anterior 

 margin, and the median impressions aureo-viridis, the latter with 

 the base, sutural and lateral margins aureo-viridis, the green area 

 along the suture on each elytron rather wide from the base to basal 

 third, then strongly constricted to behind the middle, where it is 

 expanded into a wide triangular area, which extends internally to 

 about the middle of the elytron; beneath viridis, with a feeble 

 cupreous reflection; tibiae and tarsi aeneous. 



Head feebly, evenly convex, nearly flat between the eyes, with a 

 short longitudinal carina on occiput, and without any distinct im- 

 pressions ; surface glabrous, densely, and deeply punctate, the punc- 

 tures large and becoming confluent on the front; intervals smooth 

 on the front, becoming obsoletely granulose on the occiput ; epistoma 

 wide between the antennal cavities (about three times as wide as 

 the cavities) , rather deeply arcuately emarginate in front, and with 

 an obtuse tooth on each side of the emargination. Pronotum 

 strongly convex, slightly wider than long, slightly wider in front 

 than behind, and widest near apical angles; sides feebly obliquely 

 attenuate from near apical angles to the posterior angles, which are 

 rather acute ; anterior margin with a broadly rounded median lobe ; 

 base feebly bisinuate; surface with three longitudinal impressions, 

 the median one broad and extending from the base to the front 

 margin, more deeply impressed on the basal half, and a lateral one 

 on each side about midway between the lateral margin and median 

 depression, these impressions not as deeply impressed as the median 

 one at base, and not reaching to the front margin ; the surface is also 

 regularly, densely, and coarsely punctate, the punctures deep, with 

 well-defined sides, and distinctly separated, the intervals finely and 

 densely granulose. Scutellum square and finely granulose. Elytra 

 as wide as pronotum at base, widest just a little behind the humeral 

 angles (when viewed laterally is strongly, arcuately expanded and 

 declivous near humeral angles), nearly parallel and feebly sinuate to 

 behind the middle, then arcuately attenuate to the tips, which are 

 acute, with the lateral margins finely dentate near the apex ; humeri
