nearly flat and feebly declivous superior surface of the front ; included surface 

 very strongly convex, smooth and sculptureless, having, however, posteriorly, a 

 large oval median area which is flattened or feebly indented, the lateral limits 

 of which are feebly cariniform ; supra-orbital carinse fine and rather feeble; 

 surface exterior to the ambient sulcus flattened and coarsely, rugosely sculp- 

 tured, becoming anteriorly gradually feebly declivous and minutely, sparsely, 

 subgranularly punctate, with the sides before the antennae nearly straight and 

 strongly convergent to the obtusely subangulate tip ; viewed anteriorly, the 

 frontal surface is nearly simple, greatly narrowed between the antennal cav- 

 ities, the steeper part short and separated from the short, broadly rounded and 

 simple clypeus by a very feeble short impression joining the antennal 

 cavities. Antennse obviously longer than the head and prothorax, moderately 

 slender, the basal joint cylindrical, not distinctly modified or swollen beneath; 

 second and third subequal, slightly elongate ; four to seven about as wide as 

 the third, subequal, closely joined, not quite as long as wide; eighth still 

 shorter and just visibly wider ; ninth distinctly wider but not longer than the 

 eighth, strongly transverse ; tenth large and subquadrate, its under surface 

 with a large, profound, oval, feebly transverse and abruptly defined excava- 

 tion occupying medial ^5 and basal ^ of the extent, its bottom, somewhat 

 nearer the internal than external edge, still more deeply perforate and radially 

 setulose; eleventh joint very large, still wider than the tenth, as long as the 

 preceding three combined, obliquely pointed at tip, its inner side angularly 

 subprominent just beyond the middle, the under surface feebly impressed 

 from the middle of the base, the impression smoother and less pubescent. 

 Prothorax about as long as wide, subinflated and rather prominently rounded 

 laterally well before the middle, the sides convergent and broadly sinuate 

 thence to the base; surface with a large but not very deep subpubescent fovea 

 continued anteriorly in a rapidly evanescent impression at each side, and a 

 large nude deep and more basal median fovea, feebly connected with the lateral 

 by shallow arcuate sulci anterior to the usual moderate spiniform processes; 

 median impression broad and shallow, becoming gradually narrower and 

 evanescent near apical fourth ; cariniform elevation before the spiniform pro- 

 cesses very short. Elytra convex, nearly as long as wide, barely 3^ longer and 

 ^ wider than the prothorax, the sides moderately divergent and broadly, 

 evenly arcuate from the rather prominent and broadly angulate but non- 

 spinose humeral plicae to the apex ; intra-humeral impression rather shallow ; 

 three basal fovese deep and punctiform. Abdomen but slightly narrower than 

 the prothorax and almost as long, the small basal carinse separated by rather 

 more than }'^ of the discal width ; lateral margin rather wide at base. 

 Pygidium simple, smooth, moderate in convexity. Legs rather long, the femora 

 somewhat feebly swollen. Length 1.7 mm. ; width 0.6 mm. 



Pennsylvania (Westmoreland Co.). Mr. Schmitt. 



The male type has no secondary crural modification, and the 

 venter is nearly simple, the last segment being moderate in 

 length, feebly convex and without trace of impression or central
