THE CANADIAN ENTOMOLOGIST. 151 



THE COLEOPTERA OF CANADA. 



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



XVI. The Chrysomelid^ of Ontario and Quebec — (Cont'mued). 



Tribe IV. — Clythrini, 



The species included here are of rather short, cylindrical form, 

 sometimes suggesting in shape the Cryptocephalini, though easily sepa- 

 rated, so far as our genera are concerned, by the shorter and stouter 

 antennae. Most of them are Southern or Western in distribution, and the 

 few genera recorded from within our limits may be known among them- 

 selves by these characters : — 

 A. Front coxae contiguous. 



Large ; colour, in our species, chiefly yellowish or testaceous ; 



tarsal claws simple Anomoea. 



Small ; colour in our species bluish, with four yellowish or reddish 



elytral spots Babia. 



AA. Front coxae separated by the prosternum. 



Large ; eyes transverse, emarginate Megalostomis. 



Small ; eyes oval, not emarginate Coscinoptera. 



It seems certain that Megalostomis cannot be retained as a member 

 of the Canadian fauna, as the species included therein have never been 

 found farther north than Kansas. 



Anomcea, Lac. 



Represented by Anomcea laticlavia, Forst., found occasionally on the 

 rag-weed (Ambrosia). It is apparently, however, quite a general feeder, 

 having been taken also on various legumes, and on oak, cotton, and wil- 

 low. In colour it is fulvous, elytra a little lighter, their sutural and outer 

 margins narrowly bordered with black; under side of body, excepting the 

 prothorax, dark, but densely covered with light pubescence. Legs yel- 

 low, often with tibiae and tarsi more or less blackish. The male has 

 more deeply serrate antennas and longer anterior tibiae than the female. 

 Length, .28-. 32 in. Form cylindrical. 



Coscinoptera, Lac. 



C. dominicana, Fabr. — Black; of robust form, much less elongate 

 than Anomoea. The upper surface is sparingly covered with a light- 

 coloured pubescence, the under side much more densely so. Thorax 

 densely, not very coarsely, punctured and with median smooth line.
