DESCRIPTIONS OP NEW SPECIES. 171 



GONOCALLITS LEC. 



Body elongate, slender, thinly pubescent, with long flying hairs 

 on the antennae, legs, prothorax, body, and elytra ; integuments 

 of firmer consistence than usual in the tribe; front short, oblique, 

 channelled, divided by a deep transverse line, support of labrum 

 coriaceous as usual. Eyes finely granulated, deeply emarginate; 

 genae short, prominent, rectangular. Palpi short, not very 

 unequal, last joint broadly triangular ; antenna slender, thinly 

 clothed with long pubescence, and sparsely villous ; scape rather 

 stout, more than half as long as 3d joint, 2d joint about one- 

 fourth as long as 3d joint; 4th joint a little shorter than 5th joint ; 

 llth in 9 simple, in $ very distinctly divided, outer portion 

 shorter. Prothorax shining, sparsely punctured, sides distinctly 

 angulated at the middle. Elytra elongate, densely punctured, 

 rounded at tip. Prosternum narrow between the front coxae, 

 which are transverse and broadly angulated. Mesosternum 

 triangular, obtusely rounded behind, coxae distant, open exter- 

 nally ; episterna of inetathorax not very wide, nearly parallel, 

 tubercle of scent pores very distinct; 5th ventral segment shorter 

 in and broadly emarginate. Legs slender, thighs very feebly 

 clavate, hind tibiae with distinct spurs, tarsi shorter than tibiae, 

 1st joint as long as the two following united. 



A very anomalous genus, founded on Callidium collare Kirby 

 (lepidum Lee.), a slender black species with bright red prothorax, 

 found in Canada, and on Lake Superior. By the greater firm- 

 ness of the tissues, the general appearance, the presence of 

 an additional article in the $ antennae, and the smaller size of 

 the 2d joint, it forms a connecting link with the later tribes 

 allied to Clytini ; but by the broadly angulated front coxae it 

 belongs rather to the Callidiini. 



The eyes are more inclined to embrace the base of the antennae 

 than in any other genus of the Callidioid series, and it is rather 

 to avoid making a new group in the Cerambycoides than for any 

 other reason that I have placed it here.
