than the thorax, convex, transversely excavated below the 

 basilar space, the latter slightly raised ; punctate-striate, 

 the punctures strongly impressed on the basal half of the 

 surface, finer and less deeply impressed on the basilar 

 space and behind the middle ; interspaces impressed with a 

 few fine punctures. Hinder thighs armed beneath Avith a 

 small tooth.

Late ovata, convexa, nitida, subtus nigra, supra viridi-

 punctato ; elytris regulariter punctato-striatis, disco ex- 

 teriori tricostatis.

Head smooth, distinctly punctured ; front bounded on 

 either side anteriorly by an oblique groove; four lower joints 

 of antemifB obscure fulvous, the rest black. Thorax nearly 

 twice as broad as long, sides rounded, nearly parallel at 

 the base, thence converging to the apex, basal lobe mode- 

 rately produced, obtuse ; above convex, deflexed on either 

 side in front, surface rather deeply but not very closely 

 punctured. Scutellura transverse, obtusely truncate. 

 Elytra scarcely broader than the thorax, deeply and 

 regularly punctate-striate ; three interspaces on the outer 

 disk each elevated into a strong costa, the middle one com- 

 mencing on the humeral callus, the others each occupying 

 the interspace on either side ; the three costfe, confluent at 

 the base, run downwards to below the middle of the disk, 

 when they suddenly terminate ; the upper edge of the middle 

 one is deeply sinuate. They are strongly marked in the 

 specimens from which I have drawn up the above descrip- 

 tion, but are much less distinct in all the others that I have 

 examined.
