gined with green; scutellum and elytra violaceous-black, the latter 

 with the sutural margins green, and each elytron with three deeplj?^ 

 depressed green foveae, one at the basal lobe, the second on middle 

 of disk just in front of middle, and the posterior one at apical third, 

 situated closer to the lateral margin than the suture; beneath vio- 

 laceous-black, with the median parts green. 



Head feebly convex, with the front triangular, and the sides fee- 

 bly arcuately rounded ; occiput narrow and obsoletely longitudinally 

 carinate; front with a broad concavity, which is deeper at the 

 epistoma ; vertex with an obtuse elevation, not extending to the sides, 

 and behind which, is an obsolete arcuate carina forming an acute arc 

 with the sides of front; surface coarsely and densel}^ punctate, the 

 punctures shallow, irregular and confluent on the front, becoming 

 finer along eyes and on occiput, bottom of punctures finely granulose. 

 and the intervals smooth, sparsely clothed with rather long incon- 

 spicuous hairs ; eyes large, strongly convex, more acutely rounded at 

 bottom than on top, and separated on the occiput by one-half the 

 distance between the antennal cavities; epistoma very deeply nar- 

 rowly and acutely emarginate in front, the lobe on each side form- 

 ing an arc from the bottom of the emargination, and becoming 

 nearly transverse at the sides; antennae moderately long, third joint 

 broad, strongly clavate, and about as long as the following three 

 joints united. Pronotum very strongly transverse, slightly more 

 than two times as wide as long, widest at apical third, narrower 

 behind than in front; sides strongly but not acutely angulate at 

 apical third, then feebly sinuate and strongly obliquely attenuate to 

 the posterior angles, which are nearly rectangular; anterior mar- 

 gin arcuately emarginate, with a broadly rounded obsolete median 

 lobe; base broadly angularly emarginate on each side at elytral 

 lobes, the median lobe broadly rounded, and broadly truncate in 

 front of scutellum; surface somewhat uncA^en and feebly convex, 

 with a broad obsolete impression at middle, and a smaller oblong 

 one on each side, there is also a broad transverse impression along 

 anterior margin at middle, and the sides are abruptly declivous, the 

 lateral margins sharp, straight, and not visible posteriorly from 

 above, sparsely and deeply punctate, the punctures rather fine on 

 the disk, but becoming coarser and more confluent toward the sides, 

 the surface is also feebly transversely rugose on disk, more irregu- 

 larly rugose at sides, and the intervals finely and densely granulose. 

 Scutellum very small, triangular, with the sides equal in length and 

 the surface obsoletely granulose. Elytra distinctly wider than pro- 

 notum at base; sides broadly angularly rounded at humeral angles, 

 nearly parallel to apical third, then arcuately attenuate to the tips, 

 which are produced into an acute tooth at the middle of each elytron;
