410 Goleopterological Notices, VII. 



15. C. gaudeiis n. sp. — Black, highly polished and subimpunctate, the 

 elytra faintly rufo-piceous and sometimes pale rufo-testaceous throughout from 

 immaturity ; legs piceous, the femora blackish, the tarsi pale ; antennae dark 

 rufous ; pubescence moderately abundant, long, fine and dark on the elytra. 

 Head distinctly wider than long, semicircularly rounded behind the eyes, 

 which are moderately small and but slightly prominent ; clypeal tooth strong, 

 elongate and rather narrow. Antennse scarcely J^ as long as the body, the club 

 rather abrupt but with its joints distinctly increasing in thickness and strongly 

 beaded at base ; second nearly twice as long as wide, as long as the next two 

 and slightly thicker, cylindro-obconic ; third, fourth and sixth equal and 

 slightly longer than wide ; fifth a little longer, 3^4 longer than wide ; seventh 

 very slightly thicker than the preceding joints, cylindric, }4, longer than wide ; 

 eighth % thicker and distinctly longer than the seventh, ovoidal, rather 

 longer than wide, as long as the ninth but a little narrower ; tenth scarcely as 

 long as wide. Prothorax conic, not longer than wide, the apex rather more 

 than '% as wide as the base, the latter % wider than the head ; sides very 

 feebly arcuate ; surface convex and perfectly even. Elytra oval, fully )^ longer 

 than wide, rather more than twice as long as the prothorax and % wider, the 

 sides almost evenly arcuate ; apex evenly and not very narrowly rounded ; 

 humeral plica very small, feeble and basal, the subhumeral impression very 

 short and feeble, apparently feebly bifoveate at base, the other fovea distinct ; 

 subsutural impressions wholly obsolete, the suture even and not at all elevated 

 or beaded. Legs moderately developed, the femora all rather strongly clavate. 

 Length 1.4-1.7 mm. ; width 0.6-0.7 mm. 



Canada (Ottawa). Mr. W. H. Harrington. 



The antennal and other characters detailed above are taken 

 from the male, the female being quite similar but with the an- 

 tennse somewhat shorter, the third and fourth joints quadrate. 



This species somewhat resembles fossiger in size and form, but 

 may be known by the feeble subhumeral impression of the elytra 

 and long clypeal tooth. It is represented before me by numerous 

 specimens. 



16. C. nigripenne n. sp. — Somewhat narrowly oval, highly polished 

 and impunctate, dark red-brown, the elytra black becoming indefinitely pale 

 at apex ; legs and antennse rufous throughout ; pubescence long and abundant, 

 pale in color, rather coarse on the elytra. Head orbicular, but slightly wider 

 than long, semicircular behind the eyes, which are small and but slightly 

 prominent ; clypeal tooth well developed, subtriangular, narrowly truncate at 

 tip. Antennse about }4 ^^ long as the body, the club somewhat abrupt, with 

 its joints increasing in thickness ; basal joint cylindric, more than twice as 

 long as wide ; second obconic, % longer than wide, thicker than the following 

 joints ; three to six equal in thickness, cylindric ; third not quite as long as 

 wide ; fourth and sixth subequal and slightly elongate , fifth still longer, %" 

 longer than wide ; seventh nearly ^^ thicker than the sixth and a little longer
