The CANADIAN ENTOMOLOGIST 273 



12. EreiiniJis SauMeri McUt'xW. 



Recorded from "British America." (McNeill, Pr. Davenp. Acad. 

 Nat. Sci., VI, 269, 1897.) 



13. Akeiitetus unicolor McNeill. 



SASK.— Walsh, Aug. 23, 3 (? 's, i ? . 



These specimens were determined by Prof. Morse, and are 

 very interesting, inasmuch as some of them possess rudimentary 

 accessory lateral carinae of the pronotum. In one of the males 

 there is no trace of accessory carinse, in the female they are 

 indicated only by the margins of the pale median dorsal band, 

 while in the other two males they are slightly indicated, being 

 about as distinct as the true lateral carinee. These latter speci- 

 mens are not generically separable from Amphitornus, and the 

 genus Akentetus will probably have to be reduced to a synonym 

 of the latter. 



14. Amphitonms Coloradus (Thorn.). 



Syn. — A. bicolor (Thom.). 



MAN. — Aweme. (Fletcher.^ Determinations by Scudder. )

ALTA. — Banff, below Upper Anthracite Road, Aug. 5, 1908,
