face feebly, transversely impressed near the basal margin. Elytra scarcely 

 more than }4 longer than wide, distinctly more than twice as long as the pro- 

 thorax and about *5 wider, widest Avell before the middle, the sides evenly 

 arcuate; apex rather acute ; humeral plica long and strong, the subhumeral 

 impression correspondingly distinct; foveae distinct ; subsutuial impressions 

 feeble but evident, suture somewhat beaded toward base. Legs well developed, 

 the two anterior femora strongly, the other four feebly, clavate. Length 

 1.0-1.1 mm. ; width 0.4-0.45 mm. 



Pennsylvania (Westmoreland Co.). Mr. Schmitt. 



The basal segment of the abdomen is broadly arcuate at apex 

 and somewhat elevated above the general level as in the secohd 

 subdivision of the genus, with which however the present species 

 cannot be placed because of tarsal structure. In the type, as- 

 sumed to be the male, this segment is densely clothed with long 

 submembranous hairs throughout. The female is smaller, darker 

 and more slender than the male and has the pubescence of the 

 first segment normal. 



This species may be known b}' its small and transversely im- 

 pressed pronotum, strong humeral plica and abdominal structure. 



49. C. triviale n. sp. — Rather narrowly suboval, polished, subimpunc- 

 tate, dark rufo-testaceous throughout, the legs and antennae still paler ; pu- 

 bescence moderately abundant, pale, rather coarse, moderate in length and 

 recurved on the elytra. Head slightly wider than long, subparabolic behind 

 the eyes, which are rather small and but slightly prominent ; antennal promi- 

 nences very feeble, the surface not noticeably impressed between them ; 

 dypeus not carinate, short, rectilinearly truncate. Antennae a little longer 

 than the head and prothorax, rather slender, the club long but slender and 

 quite gradual in formation ; second joint feebly obconic, as long as the next 

 two and thicker, }4 longer than wide ; next four equal in width ; third and 

 fourth equal and slightly wider than long ; fifth and sixth equal and very 

 nearly as long as wide ; seventh scarcely ^4 wider, cylindric, very little wider 

 than long ; eighth % wider than the seventh, rounded at the sides, conoidal 

 only at apex, very nearly as long as wide ; ninth and tenth almost exactly 

 equal, % wider than the eighth, less than % wider than long ; eleventh rather 

 stouter, elongate, gradually and acutely pointed and slightly oblique at apex, 

 as long as the two preceding. Prothorax conic with slightly arcuate sides, not 

 quite as long as wide ; apex % as wide as the base, the latter about Jsj wider 

 than the head ; surface feebly, transversely impressed near the basal margin. 

 Elytra almost evenly oval and widest only slightly before the middle, barely 

 % longer than wide, obviously more than twice as long as the prothorax and 

 ^ wider ; sides evenly arcuate ; apex rather narrowly rounded ; humeral 

 plica short and basal, the impression correspondingly short ; fovese distinct ; 

 subsutural impressions narrow, long and rather distinct, the suture beaded 

 l)asally, the bead rapidly expanded at base. Legs slender, the anterior femora
