296 THE CANADIAN ENTOMOLOGIST. 



Coryfubites caricimis.. Germ., iobatus, Mann. (Bull. Mosc, 1843, 243), 

 telu7n, Lee. 



This species is characterized by having an elongated thorax 

 rather densely and finely punctured above and below, with the hind 

 angles produced and non-carinate ; the antennas are elongate in the male, 

 serrate in both sexes from the 2nd joint, the 3rd and 4th being sub- 

 equal. My examples from Queen Charlotte and Vancouver Islands are 

 dull black, and no colour variations are recorded. Unalaschka, Oregon. 

 C. umbricola, Esch., Mann. (Bull. Mosc, 1843, 242). 



This species in some way has become a synonym of carichius, which 

 it resembles by its elongate thorax and parallel form ; but here the 

 likeness ceases. The thorax is more coarsely and sparingly punctured 

 above and below, though somewhat densely on the sides above ; the hind 

 angles are produced divaricately to a pointy and are finely, conspicuously 

 carinate, and blood red. The antennie (males only seen) are elongate and 

 serrate from the 2nd joint, the 3rd being notably longer than the 4th. All 

 the examples seen are shining black, with a metallic lustre, and only one 

 colour variation is recorded in which the huid angles of the thorax are 

 fuscous. Sitkha, British Columbia. My examples are from Queen Charlotte 

 Island. 



C. Iobatus, iLSch. 



This species has been placed in synonymy with caricinus, evidently by 

 oversight, because in his comparison (Bui. Mosc, 1846,) Mannerheim 

 distinctly states that loboAus has the hind thoracic angles carinate. I have 

 seen no examples of Iobatus with which to compare umbricola, but Man- 

 nerheim gives so many points of difference that it is not obvious why they 

 should be united ; both were described at the same time and on the same 

 page. Mannerheim gives six colour variations for this species, and the 

 distribution Unalaschka, the island of Kadjak, the peninsula of Kenai, 

 and the island of Sitkha. 

 Tragosoma depsarium, Linn., Harrisii, Lee 



The European and American forms are here united, for reasons which 

 v/ill appear. An example was taken in this locality this season ; it is 

 widely distribted across the northern part of the continent, from New- 

 foundland to Vancouver Island, and through the Rocky Mountains into 

 New Mexico. The punctuation of the thorax is much denser and finer in 

 examples from Canada and the Rocky Mountains, than in those from the 

 Pacific coast, in many of which the punctures are well separated. Each
