small and the inner ramus more slender than the outer ; there- 

 is also a long and slender seta attached to the spur near its base 

 and equalling it in length. 



66. C. mutilans n. sp. — Moderately stout, suboval, polished and im- 

 punctate, piceous-black, the elytra, legs and antennae dark rufous ; pubescence 

 moderately abundant, rather long and suberect but stiff, pale, and to some 

 extent recurved on the elytra. Head, clypeus and antennae nearly as in 

 lifidum, the last joint of the latter, however, less developed. Prothorax conic 

 with the sides feebly arcuate, about as long as wide ; apex rather more than 

 3^ as wide as the base, the latter fully }4: wider than the head ; surface rather 

 feebly biimpressed near the base, the impression confined to the median parts 

 of the disk as in hifidum. Elytra % longer than wide, distinctly more than 

 twice as long as the prothorax and scarcely ^ wider, widest before the middle, 

 the sides very broadly and evenly arcuate ; humeral plica large, long and con- 

 spicuous, the subhumeral impression long and very pronounced; fovese distinct;, 

 subsutural impressions narrow and moderate, the suture elevated and strongly 

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

 fringed at apex with membranous scales. Legs well developed, the femora 

 moderately clavate, the anterior more strongly. Length 1.35 mm.; width 

 0.6 mm. 



Pennsylvania ( Westmoreland Co.). Mr. Schmitt. 



This species is closelj^ allied to hifidum, but is smaller, with 

 relatively larger prothorax and narrower elytra, much larger and 

 stronger humeral plica and impression and sti'ongly beaded 

 suture. It further differs in the conformation of the posterior 

 tibial spur of the male, this being likewise abnormal in structure. 

 This spur is much longer than in hifidum, being fully f as long 

 as the tarsus, and is split from near the base into three long 

 slender filaments, which become more or less contorted at their 

 tips. The constancy of this singular modification cannot be 

 stated, as I only have a single male and two females before me, 

 but it is probably variable in degree to an appreciable extent ; the 

 splitting of the spur into filaments is, however, in all probability 

 not the result of accident.

(Scydmaenus). 



Stout and rather ventricose, polished and impunctate, dark red- 

 brown, the elytra pale and bright red throughout ; antennae dark 

 testaceous, the legs slightly paler ; pubescence abundant, long 

 even, erect and somewhat pale on the el3^tra. Head about as long^ 

 as wide, semicircular behind the eyes, which are only moderate in 

 size but somewhat convex and prominent ; antennal prominences-
