THE CANADIAN ENTOMOLOGIST. 159 



Hubbard and Schwarz, No. 54 ; Reinecke (J debiiis), No. 107 ; Dury, 

 No. 27, — all the Canada label lists. If Mr. Casey's statement cited is 

 not an error, the localities of its northern distribution are not on record. 

 B. debiiis was described from Georgia, with the remark : " not rare." 

 B. truficattis, Mots., from Alaska and California, is very easily 

 separated from the other species, and, though catalogued as a variety, 

 seems to be as good a species as debiiis. The name i?-uncatus is some- 

 times applied to certain individuals oi dubiiis'vn. which there is an evident 

 sinuosity at the apex of the elytra, but this is different from that in the 

 true iruncatus, and other secondary characters are absent 



Rhopalophora longipes, Say, and R. Afeeskei, Casey, (Ann. w. Y. 

 Acad. Sci. VI., 30. — R. longipes occurs here occasionally in June ; when 

 found it is in abundance, and twenty-eight examples are before me. 

 There are also before me from St. Fe Canon, N. M., seven examples of 

 what Mr. Casey describes as R. Meeskei, but which can scarcely be con- 

 sidered more than a slight geographical variation of longipes. Although 

 Mr. Casey states he had before him a good series of lofigipes from Indiana, 

 it could not have been such a miscellaneous lot as is before me or he 

 would scarcely have written the conspectus. 



" Prothorax narrow, truncate at base, not impressed dorsally. — 

 lojigipes.^^ 



" Prothorax broader, feebly biimpressed dorsally, broadly, strongly 

 emarginate at base ; form more robust. — Afeeskei. 



The twenty-eight examples before me exhibit great instability in 

 length, breadth and sculpture of the thorax ; in some of the (^ (^ it is fully 

 one-third longer than wide, and in others, both $ and $ , subequal ; in 

 the majority of individuals of both sexes however it is evidently longer. 

 As to sculpture, all the individuals have a wide constriction at apex 

 occupying about one-third of the length of the thorax, and more or less 

 evident, which is sometimes interrupted at middle by a dorsal subcarina ; 

 the transverse basal impression is narrow, and in all there is an obtuse 

 tubercle on each side behind the middle more or less prominent. Some 

 individuals have a carina between these tubercles extending from near the 

 base to the apical constriction, often continued forward obtusely ; on each 

 side of this carina is a broad oblique impression which connects behind 

 the carina with the other and the transverse basal ; the tubercles 

 mentioned are situate behind this discal impression and appear more or 

 less elevated according to its depth ; the punctuation becomes coarser a§
