feebly developed ; tempora long, feebly convergent and only slightly arcuate 

 behind the eyes to the base and there abruptly constricted, the neck fully J^ 

 of the maximum width ; surface finely, sparsely punctulate and sparsely and 

 inconspicuously pubescent in basal half, perfectly smooth and glabrous an- 

 teriorly, becoming very slightly concave behind the transverse frontal margin, 

 which is broadly and angularly prominent in the middle. Antennas a little 

 shorter than the head and prothorax, rather slender, the club gradual, with 

 the last two joints notably larger ; basal Joint cylindric, more than twice as 

 long as wide, nearly as long as the next three, bent toward base, extending 

 tinder the frontal margin ; second but little thinner, oval, rather longer than 

 wide, much thicker than the third, the latter smallest, much wider than long ; 

 four to seven subglobular and a little thicker, becoming a little more trans- 

 verse ; eighth decidedly shorter and more transverse but not distinctly wider ; 

 eight to ten increasing rapidly in width and length, the latter % wider than 

 long, equal in width to the eleventh, which is subcylindric, closely connected 

 to the tenth, nearly as long as the two preceding and very obtuse at apex ; 

 fifth a little longer than the fourth or sixth. Frothorax rather distinctly 

 longer than wide, % wider than the head, widest rather behind apical third, 

 the sides evenly and strongly rounded, becoming convergent and feebly sinu- 

 ate toward base ; disk with a small fovea at each side of the middle near the 

 base, the lateral fovea scarcely visible even as a trace. Elytra barely % 

 longer than wide, scarcely twice as long as the prothorax and % wider, the 

 sides rather strongly oblique from basal % to the apical truncature ; humeri 

 somewhat evident ; disk perfectly even, without trace of basal impressions. 

 Legs moderate in length, rather slender, the femora feebly clavate, the an- 

 terior somewhat more distinctly so. Length 1.05 mm. ; width 0.35 mm. 



Pennsylvania (Westmoreland Co.). Mr. Schmitt. 



The male described above differs conspicuously from the female, 

 the latter having the head narrower, more parallel, rather longer than 

 wide, equally pubescent throughout, and not concave behind the 

 truncate frontal margin, which is only very feebly and obtusely sub- 

 prominent at the middle ; the ej'es are nearly as in the male, the 

 antennae a little more slender, with the basal joint not quite as long 

 and the fifth joint not evidently larger, but otherwise similar, and 

 the elytra are very slightly shorter and more inflated. In the 

 male the fifth ventral segment has a deflexed and cuspid apical 

 margin, the cusp obtusely angulate and finely pubescent, and the 

 sixth has a large rounded median excavation, which is feebly con- 

 cave, glabrous and polished, with its edges prominent at the sides 

 posteriorly but not at the middle of the apex. In the female the 

 last two segments are perfectly simple, the fifth not longer than 

 the fourth and the sixtli a little longer, evenly and broadly para- 

 bolic at apex.
