vittae vary in width, but never reach the apex. C. flavo- 

 limhatus is also considerably smaller than C. vittatus. 

 The form of C. confluens, Lee, with longitudinally confluent 

 elytra] markings comes near the present species; but in 

 C. confluens the head and elytra are more coarsely 

 punctate, and the basal joint of the (^-antennae is 

 slender and entirely testaceous, A female of Leconte's 

 species has been sent me by Mr. Fall. There is a 

 specimen ((^) of C. flavolimhatus in the Oxford Museum 

 labelled " N. America."

This species, of which two females (including one of 

 Erichson's types) are before me, has the head nigro- 

 violaceous and very finely punctate; the antennae long 

 and stout, with joint 1, and the outer edges of 2 and 3, 

 testaceous ; the prothorax unusually long, subcordate, 

 rufous, with a transverse ante-median black fascia; the 

 elytra closely, rather coarsely punctate, cyaneous, with 

 three flavous spots placed transversely before the middle — 

 one, common, extending narrowly down the suture to the 

 tip, the others isolated, marginal; the upper surface 

 shining, finely, sparsely cinereo-pubescent, and also set 

 with long erect black setae.]

 into a large, broad, spoon-shaped, ciliate, hollow plate, which is 

 followed by an angular vertical expansion of the margin, the cavity
