terior half of the black pigment area ; upper surface feebly and 

 evenly'- convex, finely, sparsely punctulate, evenly covered with 

 short, inclined and coarse hairs, which are evenly and posteriorly 

 oblique in direction at each side of the median line throughout ; 

 front broadly truncate, with a small and tumid cusp in the middle. 

 Antennse very approximate, inserted under the frontal surface, as 

 long as the head and prothorax, stout, incrassate toward tip ; 

 basal joint cylindric, | longer than wide, but little thicker than 

 the second, slightly longer than the next two; second stout, as 

 long as wide, rounded at the sides, much stouter than the third, 

 which is ^ wider than long ; three to eight increasing very slowly 

 in width ; nine to eleven equally gradually bat more rapidly 

 thicker; all the joints moderatel^^ transverse, except the fourth, 

 which is almost as long as wide ; ninth scarcely |- thicker than the 

 eighth ; eleventh about as long as wide, not quite as long as the 

 two preceding, obtusely pointed. Prothorax as long as wide, f 

 wider than the head, widest at apical third ; sides parallel and 

 evenly, circularly rounded, becoming strongly convergent and 

 feebly sinuate toward base ; disk very convex, with a small and 

 deep perforate fovea at each side of the middle near the base, 

 and another more minute and lateral. Elytra almost |- longer than 

 wide, a little more than twice as long as the prothorax and ^ 

 wider, ovulate, widest and more prominent at the sides behind 

 basal third ; disk perfectly devoid of impressions. Legs slender, 

 the femora feebly clavate. Length 1.35 mm.; width 0.45 mm. 



Pennsylvania (Westmoreland Co.). The description is derived 

 from the male, but the female is nearly similar, having the head a 

 little narrower and as long as wide, more triangular, the sides be- 

 hind the eyes more feebly arcuate and the small frontal cusp not 

 tumid, the antennse fully as long but not quite so stout, and the 

 elytra just visibly shorter and more inflated ; there is but little 

 sexual difference in the eyes. In the male the last two ventral 

 segments are a little longer than in the female, the fifth in the lat- 

 ter not being longer than the fourth ; but in both sexes they are 

 perfectly simple and unmodified, the sixth evenly rounded be- 

 hind. 



2. li. cavifrons n. sp. — Narrowly suboval, very convex, polished, subim- 

 punctate, pale rufo-testaceous throughout ; pubescence very short, even, rather 

 sparse, decumbent and inconspicuous. Head oval, as lono; as wide, the eyes 

 anteriorj rather well developed but only slightly convex, and with the facets
