obsolete; clypeus long, even, with sparse setse, the apex not 

 toothed. Antennae long and slender, rather more than ^ as long 

 as the body, the club slender and rather abruptly formed ; second 

 joint stout, feebly obconic,f longer than wide, thicker but scarcely 

 as long as the next two ; three to six equal in width, the first 

 three smooth, the sixth asperate like the following ; third scarcely 

 as long as wide ; fourth just visibly longer than wide ; fifth full}' 

 ^ longer than wide ; sixth similar to the fourth but cylindric and 

 not feebly obconic in form ; seventh scarcely i wider than 

 the sixth, distinctly longer than wide ; eighth -§■ wider, as long as 

 wide, rounded in apical half; ninth and tenth almost similar, just 

 visibly wider than the eighth, nearly as long as wide ; eleventh 

 large, stouter, obliquely pointed, very nearly as long as the two 

 preceding. Prothorax strongly conic, with very feebly arcuate 

 sides, not quite as long as wide ; apex ^ as wide as the base, the 

 latter fullj'- ^ wider than the head ; surface distinctly biimpressed 

 transversely near the base. Elytra -J longer than wide, oval, 

 widest only slightly before the middle, much more than twice as 

 long as the prothorax and ^ wider; sides strongly arcuate; apex 

 narrowly obtuse ; humeral plica long and very strong ; impres- 

 sion large and very conspicuous ; inner fovea distinct ; subsutural 

 impressions very strong, the suture conspicuously and broadly 

 beaded basally, the bead expanded at base. Abdomen with the 

 basal segment fringed at tip with long hairs and short porrect 

 membranous scales, black, the tip rufous. Legs long, the femora 

 subequally and rather strongly clavate. Length 1.6 mm.; width 

 0.8 mm. 



Massachusetts, Rhode Island (Boston Neck) and District of 

 Columbia, probably of wide distribution in the coastal plains of 

 the Atlantic region. 



The description is drawn from the male, and, in that sex, the 

 hind tibiae have at tip a straight slender and simple spur, scarcely 

 half as long as the tarsus, bent obliquely outward near the base. 

 The female does not differ from the male except in some slight 

 details of antennal structure, the sixth joint, for example, being 

 smooth like the preceding and the club rather narrower and more 

 elongate. 



68. C proxixaum n. sp. — Stout, highly polished and impunctate, 

 piceous-black, the elytra bright red ; antennse piceous-brown, the legs dusky- 

 testaceous with the tarsi pale flavate; pubescence abundant, rather pale, long
