" Xcw York, in ants' nests, with Hfctcrhis brunnipennis, March 

 and April. This species is much broader and more suddenly 

 naiTOwed posteriorly tl\an the others. The thorax is fully twice 

 as wide as its length, punctulatc, not strigose, strongly narrowed 

 in front, broadly rounded on the sides, truncate at base, with 

 the posterior angles simply rectangular and not produced. The 

 elytra are punctulatc and distinctly striate transversely. The 

 antennae are as long as the head and thorax, very slightly incras- 

 sated, rufo-piceous, with the first four joints and the apical one 

 yellowish ; the seventh joint is more than twice the length of 

 the sixth ; the eighth joint is much shorter, but scarcely thinner 

 than the following ones. The anterior tarsi of the male are 

 broadly dilated ; the first joint of the middle tarsi is less dilated 

 than in C. terminans*." 



The mesosternal keel is finer and less raised in this and 

 C. oblitus than in the other species.

Fuscous-brown. The antennae are scarcely so long 

 as the head and thorax, so slightly clavate as to be almost 

 filiform, fuscous, the basal joints ferruginous, the two apical 

 joints pale ; first and second joints long and slender, those follow- 

 ing short, gradually though very slightly increasing in breadth 

 up to the seventh ; the seventh is rather shorter than the ninth, 

 and of about the same thickness ; the eighth is not narrower than 

 those on each side of it, but shorter, being about half the length 

 of the ninth ; the ninth and tenth are equal in length and thick- 

 ness ; the eleventh is larger than the tenth, and becomes acu- 

 minate towards the point. The head is darker than the rest of
