plica and subhumeral impression very small and inconspicuous ; 

 fovese obsolete, the inner existing only as a trace ; subsutural im- 

 pressions wholl}' obsolete, the suture not elevated. Abdomen 

 rather convex, the first segment rather shorter, the last two 

 longer, than usual ; fifth equal to the two preceding. Legs mod- 

 erate, the tarsi rather thick, the first four joints of the posterior 

 equal ; anterior femora somewhat strongly, the four posterior 

 feebly, clavate. Length 0.8-0.9 mm.; width 0.3-0.35 mm. 



Appalachian mountain system, from JSTew York to northern 

 Georgia. This species may be known at once \)y its minute size, 

 3-jointed club, feeble modification at the base of the elytra, ab- 

 dominal structure and pale coloration. It is said by LeConte to 

 occur under pine bark, but its very coua'cx form would suggest 

 the accidental nature of such a habitat. The type is a male, the 

 copulatory spicule being very slender and without a terminal 

 button. 



63. C. repilguans n. sp. — Moderately stout, not very ventricose, 

 polished, impunctate, dark rufo-testaceous throughout, the legs and antennse 

 concolorous ; pubescence abundant, long, erect, coarse, pale and conspicuous 

 on the elytra. Head nearly as long as wide, parabolic behind, the eyes 

 moderately large, rather convex and prominent ; front feebly concave ; clypeus 

 long and well developed, coarsely and sparsely setose, the apical margin trans- 

 versely rectilinear, with a small but distinct and equilaterally triangular 

 median tooth. Antennee distinctly less than % as long as the body, only 

 moderately slender, the club somevphat abrupt but elongate and paler in color; 

 second joint stout and but feebly obconic, scarcely % longer than vi-ide, 

 distinctly shorter than the next two but much thicker ; three to six equal in 

 width ; third and sixth equal and quadrate ; fourth and fifth slightly longer 

 than wide and about equal ; seventh ^^ wider and J^ longer than the sixth, 

 parallel, with arcuate sides, slightly longer than wide ; eighth fully % wider 

 than the seventh, oval, truncate at base, fully as long as wide ; ninth and tenth 

 very nearly equal and scarcely visibly wider than the eighth, both fully as long 

 as wide ; eleventh not thicker, gradually acutely and obliquely conic from the 

 middle, scarcely as long as the two preceding. Frothorax conic with slightly 

 arcuate sides, nearly as long as wide ; apex rather more than }4 ^-s wide as the 

 base, which is fully }4: wider than the head ; surface strongly impressed 

 transversely near the base, the impression not interrupted at the middle. 

 Elytra long, % longer than wide, much more than twice as long as the 

 prothorax and about ^5 wider, with the sides very broadly and evenly arcuate, 

 widest before the middle ; humeral plica long and very strong, the subhumeral 

 impression rather large and conspicuous ; fovese small but distinct ; subsutural 

 impressions very strong, the suture strongly beaded basally, the bead scarcely 

 at all expanded at base. Abdomen with the first segment widely overlapping 

 the next, arcuate at apex and with a very deep pale coriaceous border, which is
