COLEOPTEBA COLLECTED IN CANADA. 35 



NECKOPHILA 



TERMINATA, Kirb. N. Z. 103. 



Antennae and head black, the frontal impression between the eyes 

 oblong; thorax minutely and confluently punctured, margined yel- 

 low — the discoidal spot black, and very slightly lobed at the sides, 

 with a yellow sphenoid spot inserted posteriorly ; elytra brown 

 black, and minutely punctured, with two longitudinal obsolete ridges 

 and a row of distinct punctures on each side of the suture — yellow 

 at the apex ; beneath black. Length 9 lines. Toronto, not common. 



AFFINIS, Kirb. N. Z. 103. 



Head and antenna? black, the frontal impression not so deep ; tho- 

 rax pale yellow, very finely punctured — discoidal spot smaller and 

 differently formed than in the last species — the lateral lobes are 

 larger and more oblique — the posterior part is rather of a deltoid 

 form and slightly sphenoid in the centre with yellow ; elytra of a 

 brown silky color, with the same irregular elevations and sutural 

 rows of punctures as in terminata ; the apex of elytra yellow, body 

 beneath, and legs black. Length 9 lines. Toronto, rare. 



This and the preceding species are nearly related to N. Americana, 

 Linn., the true northern type of the genus. Kirby describes four 

 species which he states are closely related to the latter. N. Cana- 

 densis is evidently the $ of Americana. I have noticed invariably 

 both the form of the thoracic discoidal spot, and the color of epi- 

 pleura, to vary in almost every specimen; also, in the smaller speci- 

 mens the sutural termination of elytra are not so acuminate ; pro- 

 bably it may be, as he states, a sexual character. 



LATHKOBIUM 



PUNCTICOLLIS, Kirb. N. Z. 86. Erichs- p. 604. 



Head obovate, minutely punctured ; antennae, mandibles and palpi 

 dark chesnut ; thorax " oblong square with all the angles rounded, 

 punctured, but not thickly ;" elytra of a dark chestnut color, longer 

 than wide — not much longer than thorax, and thickly punctured ; 

 posterior part of the body black, and covered with very short glossy 

 hairs ; beneath black glossy ; legs bright mahogany ; tibia? armed 

 with a spine. Length 5 lines. Toronto, common. Taken in lat. 

 BV—Kirhj.
