THE COLEOPTERA OF CANADA. 



BY H. F. WICKHAM, IOWA CITY, IOWA. 



XXIV. The Cerambycid.e of Ontario and Quebec. — (Conthmed.) 



MoLORCHUS, Fabr. 



Easily recognized by the very short elytra which are divaricate and 

 separately rounded at apex, about equalling the prothorax in length. M. 

 bimaculatus. Say (fig. 23), is somewhat variable in colour, 

 but is ordinarily black except a large testaceous blotch on 

 each elytron. The thorax is rather broad, roughly 

 punctured, the sides irregularly rounded, Length, .20- 

 .32 in. Usually found on flowers, but has been bred 

 from hickory, maple, ash, and dogwood. 



Callimoxys, Kraatz. * 



Distinguished from Molorchus by the shape of the 

 elylra, which are longer and drawn out nearly to a point 

 at tip. The sexes differ in colour, the males usually hav- "" ^^' 



ing a partially red thorax. C. sanguhiicollis, Oliv., is blackish (except as 

 Stated above), punctured, the elytra more or less fuscous with clear 

 punctuation. Anterior and middle legs entirely blackish, the posterior 

 yellow except the tips of the joints, which are black. The hind tibiaj are 

 long and curved in the males, the exterior margin with numerous teeth. 

 Length, .33-.40 inch. Found ou flowers in June and July. 



Ancylocera, Serv. 



It may be that the Canadian record for A. bicolor, Oliv., is incorrect, 

 since the species is said to be a resident of the Southern States from 

 North Carolina to Texas. It is unknown to me in nature, but is said by 

 Mr. Leng to be " a very dainty insect, black with scarlet elytra and 

 abdomen and with slender legs and clubbed thighs. The body is slender, 

 head short and prothorax very long as compared with the cylindrical 

 elytra. The antennae are serrate, one-half as long as the body in the 

 female and longer than the same in the male. The hind pair of thighs is 

 armed with a terminal spine." Length, .50-. 70 inch. 



Batyle, Thorns. 



B. ignicollis, Say, is from .2 8-. 5 2 in. long, black, the prothorax 

 bright red. The elytra are densely rugosely punctured, with blackish 

 pubescence. The prothorax is rounded, unarmed, the pubescence longer 

 than on the elytra, B. suturalis is snialler (.28-.36 in.), red, the legs
