AMERICAN ENTOMOLOGY. 119 



slightly hairy at base ; each with an oval, oblique spot near the 

 basal middle ; then a subsutural line proceeding from near the 

 basal spots to the sutural middle, thence it curves over the disk, 

 and terminates in a small spot rather before the middle on the 

 exterior margin j an oblique line behind the middle passses from 

 the suture outward ; all these bands and spots are yellow ; disk- 

 near the tip obsoletely obscure fuscous ; the tip rounded, unarmed ; 

 beneath spotted and banded with yellow : feet rufous : thighs at 

 tip dilated, compressed, black. 



Obs. Has some resemblance to C. arietis Fabr., of Europe 

 but besides other points of distinction, the elytra are not remark- 

 ably truncated as those of that species are. It seems also to be 

 allied to 0. arvicola and auricola Oliv., and particularly to the 

 latter, from which, however, it may be distinguished by its larger 

 size, by having the thorax nearly surrounded by a yellow line, 

 and by the obliquity of the terminal band of the elytra. I ob- 

 tained it near the Illinois river.

Clytus UNDULATUS. — Specific character. Brown ; thorax sub- 

 bifasciate ; elytra with a spot and three bands, yellow. 



C. undulatus nobis, Long's Second Expedition, vol. ii. p. 291. 



Desc. Body dark brown : head darker than the elytra ; antennae 

 dark ferruginous; front, below the antennae, bilineate with pale 

 yellow : thorax darker than the elytra, rough with minute spines 

 and hairs ; anterior and inferior margins yellow, interrupted above > 

 basal margin with a transverse yellow spot each side : elytra with 

 a transverse spot on each near the base ; an undulated narrow band 

 across the middle, rising along the suture nearly to the scutel ; an 

 undulated transverse band behind the middle, and a terminal band; 

 postpectus with the incisures margined with yellow : venter, 

 having the segments margined with yellow. 



Obs. I caught the two sexes of this species in the North West 

 Territory, when traversing that part of the Union with Major 

 Long's party. It seems to have some resemblance to the C. mu- 

 cronatm Fabricius,of South America ; but the elytra are not mu- 

 cronate, and the markings of the superior surface of the body 

 are different.
