transverse, rounded behind and smooth, with a transverse depres- 
sion at the base. Elytra a little broader than the thorax and 
nearly twice the length, with a strong stria on each side of the 
suture, the rest punctate, the punctures large and in rather 
irregular rows, growing more crowded towards the sides, — 
excepting a space near the suture, widest at the base, which is 
almost impunctate. The legs ai-e short, strong, spinous, and 
ciliated, the anterior tibiae broadly and flatly tridentate. 
Long. 8, lat. 4 lines. 
In an insect which I take to be the female of this species, the 
occiput is smooth, and there is no trace of a tubercle at the apex 
of the thorax. 
174. IsoDON PiciPENNis, n.sp. 
Oblong-ovate, black, nitid, elytra piceous-red. Head small, 
transverse, clypeus like the last species, but the apex more trun- 
cate. Thorax transverse, narrowed at the apex, large, rounded 
on the sides, much wider at the base than the apex, largely and 
roundly excavated in the middle on the anterior half, with a short 
conical tubercle on the anterior margin, and punctate only on the 
anterior and lateral mai'gins. Scutellum as in the last species. 
Elyti’a the width of the thorax and one and a-half times the 
length, punctate and marked as in the preceding, but the punc- 
tures coarser and more rugose, and the smooth space on each side 
of the sutural stria of less width. The legs strong, the anterior 
tibia} with three strong, flat, and obtuse teeth. 
Long. 6J, lat. 3^ lines. 
175. ClIEIROPLATYS 0CCIDENTALI3, n.Sp. 
Ovate, black, nitid. Head small, transverse, rugosely punctate, 
the clypeus finely punctate, narrowed in a straight line towards 
the apex whicli is sub-truncate, the clypeal suture straight and 
ridged. Thorax narrow in front, much rounded on the sides,
