THE CANADIAN ENTOMOLOGIST. 



Hylotrupes, Serv. 



The two species of this genus are very different in appearance. 

 H. bajulus, Linn., is blackish, pubescent above, more thickly on the pro- 

 thorax, where the hair is whitish, almost covering the surface except on 

 ihe elevated median line and the two raised callosities, which are thus ren- 

 dered very conspicuous. The elytra have two indistinct transverse fasciae 

 of whitish pubescence, one in front of the other behind the middle, the 

 latter sometimes wanting. Length, .72 to .88 in. Depredates in pine and 

 juniper. II. iigneus, Fabr., is extremely variable, the thorax usually 

 black, less hairy than in bajulus, and with five callosities. Elytra yellow- 

 ish or reddish, with a large blackish blotch occupying usually the apical 

 third, and an elliptical spot of the same colour but varying in size between 

 this blotch and the base. Bores in juniper in the larval state, perhaps 

 also in pine, as the beetle is found on piles of lumber or on freshly con- 

 structed fences. Length, .30 to .45 inch. 



Merium, Kirby. 



M. proteus, Kirby, is .45 to .60 inch long, thorax metallic blue or 

 violaceous, shorter than usual, varying in shape according to sex, densely 

 punctured and rather opaque at sides, but shining and with only a few 

 large punctures at middle. Elytra usually greenish metallic, densely and 

 coarsely punctured, generally with two raised longitudinal yellowish lines 

 before the middle, the side margin also yellowish in some specimens. 

 Thighs reddish yellow, except at base and apex, which, with the tibiae and 

 tarsi, are blackish. Beneath shining black with a violaceous tint, 

 Chion, Newm. 



Here belongs Chion cinctus, 



Drury, a large beetle of a brownish 



colour (fig. 18), sparsely clothed with 



whitish pubescence, each elytron 



usually with an oblique blotch of a 



yellowish colour near the base. The 



prothorax is nearly round, and bears a 



small spine on each side. The elytra 

 are each bispinose at tip. The male 

 antennae greatly exceed the body in 

 length. The species reaches a size of 

 from .75 to 1.5 inch. It is known to 

 breed in hickory. The i\dixne. gargani- 

 cus, Fabr., catalogued as a variety, 



refers to the spotted form. Fig. iS (after Harris).
