the head; surface with feeble traces of a transverse impression near the hasal 

 margin. Elytra % longer than wide, scarcely twice as long as the prothorax 

 and about % wider, widest slightly before the middle, the sides broadly arcu- 

 ate; humeral plica very narrow but elongate and distinct, the impression rather 

 well developed; fovese distinct; subsutural impressions obsolete, the suture 

 not or scarcely beaded basally. Legs rather long; anterior femora strongly, 

 the four posterior feebly, clavate. Length 0.85 mm. ; width 0.35 mm. 



Pennsylvania (Westmoreland Co.). Mr. Schmitt. 



No sexual marks can be discovered in the two examples before 

 me ; there will, however, be no trouble in identifying this distinct 

 species, because of its small size, coloration of the body and pe- 

 culiar form of the prothorax.

Narrow and elongate, polished, sparsely subpunctulate, rufo- 

 testaceous, the legs and antennae pale ; head and pronotum slightly 

 darker; pubescence rather abundant, coarse, pale, short, recurved 

 and interspersed with longer remote erect setae on the elytra. 

 Head large, but slightly wider than long, the eyes small ; clypeus 

 with a minute discal tubercle at the anterior margin, the latter 

 transverse. Antennae about as long as the head and prothorax, 

 slender, the club rather strong, subparallel and abrupt to some 

 extent; second joint rather longer than the next two and dis- 

 tinctly thicker, f longer than wide ; three to six almost equal, 

 cylindric, distinctlj^ wider than long, the fifth almost as long as 

 wide ; seventh ^ wider, cjdindric, ^ wider than long ; eighth ^ 

 wider and longer than the seventh, a little wider than long; ninth 

 and tenth subequal, ^ wider than the eighth, about |- wider than 

 long ; eleventh almost as long as the two preceding and some- 

 what thicker, ogival and slightly oblique at tip. Prothorax fully 

 as long as wide, the sides arcuate and converging anteriorly, 

 parallel toward base ; apex | as wide as the base, the latter onlj'- 

 very slightly wider than the head ; surface transversely^ and 

 strongly impressed near the base, the impression narrowly inter- 

 rupted at the middle. Elji'tra ^ longer than wide, twice as long 

 as the prothorax and barely \ wider, evenly oval, the sides 

 broadly arcuate ; humeral plica and adjacent impression small 

 and moderately strong ; inner fovea evident, the outer subobsolete ; 

 subsutural impressions nearly obsolete, the suture verj^ finely 

 beaded basally. Legs moderate, the femora rather strongly
