ally; pygidium convex, with coarse, shallow but impressed, well 

 separated areolae, the apex more shining and with a transversely 

 oval pit, deep to evanescent; hind tarsi moderately compressed, 

 slightly shorter than the tibiae. Length 8.2-10.5 rnm.; width 

 4.0-5.1 mm. New York to North Carolina. Common. [Crem. 

 lecontei Westw.] castaneae Knoch 



Body nearly as in castanets but somewhat smaller and narrower, the sparse 

 vestiture very short, moderately coarse, the elytra without lateral 

 cretaceous spot in the type; head nearly similar; prothorax smaller 

 in size, one-half wider than long, almost similar in form and in the 

 coarse sculpture, except that the punctures are more close-set, the 

 basal angles more acute and more densely punctulate, but otherwise 

 almost similarly formed; scutellum and elytra nearly similar in 

 general characters, but with the sculpture of the latter much coarser 

 and more rugose; pygidium with smaller areolae, the apical impression 

 obsolete; legs almost as in castanece, the hind tarsi nearly as long as 

 the tibiae. Length 8.7 mm.; width 4.2 mm. Manitoba (Aweme), 

 Criddle pocularis n. sp. 



Body somewhat as in castanece in form and size but with the prothorax 

 more nearly as in retractus, except that the hind angles are less 

 retracted, being scarcely more so than in castanece, the punctures much 

 smaller than in that species and nearly as in retractus and, as in the 

 latter species, becoming notably shallower and sparse basally; head 

 deeply, subconfluently punctate, the abruptly reflexed clypeus 

 broadly sinuate when viewed vertically, arched as usual viewed 

 anteriorly; emargination of the mentum not so large as in castanece, 

 deeper and relatively narrower than in retractus; prothorax in form 

 and in the nature of the apical and basal angles almost exactly as 

 in castanece, but not quite so short, with much less coarse and more 

 close-set punctures, bearing each, not a long erect hair, but an ex- 

 tremely short broad scale-like hair, the nodule of the apical angles 

 larger and more elongate, that of the hind angles similarly depressed 

 but more rectangular; scutellum with shallow foveae, sparse apically; 

 elytra nearly as in castanece but with the areolae less elongate and 

 bearing very small erect hairs; pygidium convex, flattened and 

 smooth at apex, having coarse uneven separated punctures, which, 

 basally, become very fine, each bearing a minute hair; hind tarsi 

 compressed, not quite as long as the tibiae, each joint with a basal 

 impression on the outer side. Length 10.0 mm.; width 4.5 mm. 

 Iowa (locality unrecorded). A single specimen . . brevisetosus n. sp. 



6 Legs and entire body deep black, dull above, shining beneath; ves- 

 titure rather abundant, moderately long, erect, very coarse, the hairs 

 thick at their bases, becoming sharply pointed apically; head deeply 

 and closely punctate, shining, the strongly reflexed and broadly 

 sinuate clypeus polished and sculptureless; prothorax one-half 

 wider than long, the sides abruptly transverse near basal third to the 

 bottom of the deep sinus bounding the sharp depressed hind angles 

 externally, feebly arcuate and slightly converging thence unbrokenly 

 to the apex of the apical processes, which are bounded internally by 

 large deep cavities having, as usual, a dense tuft of short setae on
