 found in the Revision of the Coccinellidae of the U. S. by Mr. G. R.

 described since the publication of his memoir.

PEPL,OGLYPTlTS n. g. (Histeridje). 

 Body oblong, costate, elytra a little wider than the prothorax. 

 Head broadly concave, front acute anteriorly; antennae very strongly 

 geniculate, scape nearly as long as the funicle, which is slender, club 

 oval, pointed, annulated. Prothorax less than one-half wider than 

 long, sides oblique, slightly sinuate in front of the middle, apex emar- 

 ginate, base oblique each side, lateral edge acute, disc longitudinally 

 deeply concave near the margin, but more deeply so near the lateral 

 sinuosity; this concavity is limited on the inner side by a sinuous 

 impressed line. Scutel very small. Elytra oblong, with the suture, 

 three discoidal ridges and the margin acutely but feebly elevated ; 

 epipleurae flat. Pygidium perpendicular not sculptured. Beneath 

 nearly smooth ; prosternum wide with the anterior lobe lar^e, front 

 coxae widely separated, hind margin broadly truncate and feebly emar^'in- 

 ate, antennal cavities small, transverse, situated under the front angles 

 near the anterior margin ofthe flanks. Tibiic long, slender, front pair 

 gradually slightly dilated as far as the middle, then obtusely an"-ulated 

 on the outer side and nearly parallel to the apex; middle and hind 

 pair slender, very feebly dilated, tarsi more than half as lon<j- as the 

 tibia?, claws equal as usual.
