Goleopterological Notices, VII. 447 



% wider than the eighth and nearly twice as long, }{ wider than long; tenth 

 just visibly wider, similar in form; eleventh rather stouter, not as long as the 

 two preceding; the ninth and tenth have a whorl of peculiar short, very stiff 

 and porrect bristles at apical %, which are distinct from the ordinary erect setse 

 or shorter hairs, and there is also a feebler whorl of similar setae at about the 

 middle of the eleventh. Frothorax conic with nearly straight sides, as long as 

 wide; apex fully ^ as wide as the base, the latter }4 wider than the head; 

 surface perfectly even. Elytra % longer than wide, twice as long as the pro- 

 thorax and ^ wider, narrowly rounded behind, widest near basal third; sides 

 broadly rounded ; humeral plica short, narrow and not very pronounced, the 

 adjacent impression rather small and feeble; inner fovea small but deep and 

 distinct, the outer obsolete; subsutural impressions small but rather distinct, 

 rounded, at basal fifth, the suture extremely finely and feebly elevated to- 

 ward base. Legs moderate, the four posterior femora rather feebly, the an- 

 terior more strongly, clavate. Length 1.0 mm. ; width 0.38 mm. 



Pennsylvania (neai* Philadelphia). 



The single specimen, which is probably a male, represents a 

 species allied to /"uZuMm and trijidum, but differing in its much 

 stouter antennae, especially in the funicular portion. The subhu- 

 meral plica and impression are much more pronounced than in the 

 former, but rather less so than in the latter, and the subsutural 

 impressions and clypeal tooth are more developed than in either 

 of those species. In form it more nearly resembles fulvum, being 

 less stout than trifidam. The last two segments combined occupy 

 nearly half of the entire abdomen. 



61. C. trifidum n. sp. — Somewhat stout, suboval, polished, subimpunc- 

 tate, pale brownish-testaceous throughout, the legs and antennse concolorous ; 

 pubescence rather abundant, pale, coarse, rather short and recurved on the 

 elytra, where it is mingled with a few widely dispersed and erect tactile setae 

 of moderate length. Head moderate, but very slightly wider than long, 

 rounded behind, the eyes small and slightly convex ; antennal prominences 

 very feeble, the front scarcely impressed ; clypeus simple, sparsely asperate, 

 the apical margin with an exceedingly minute and obtuse median tooth. 

 Antennse barely as long as the head and prothorax, slender, the club abrupt, 

 stout and 3-jointed ; second joint very feebly obconic, }4. longer than wide, 

 longer and much wider than the next two ; three to six equal, cylindric, 

 about % wider than long ; seventh nearly )4 wider than sixth, fully }4. wider 

 than long ; eighth nearly }^ wider than the seventh and almost similar in form; 

 ninth abruptly % wider than the eighth, fully % wider than long ; tenth 

 similar to the ninth but just visibly wider ; eleventh not quite as long as 

 the two preceding. Prothorax conic with very feebly arcuate sides, about as 

 long as wide ; apex truncate, % as wide as the base, which is nearly 3^ wider 

 than the head ; surface perfectly even and unimpressed. Elytra about % 

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