IS THE CANADIAN ENTOMOLOGIST. 



from Calgary. The type, which is in the National collection at Washington, 

 was taken at treacle near the mouth of Fish Creek on June 22nd, 1893. 

 It has turned up amongst Pine Creek hills in 1896, 1899 (one only) and 

 1904. End June to middle July, and all, I think, at treacle. I have not 

 yet heard of its occurrence in any other locality. A handsome species, 

 and not easily mistaken. A figure is given with the description. 



155. H. (X.) morna,^\.xQck. — A single $, June 19th, 1897. The 

 species looks to me rather like a pale variety oi passer, in which species the 

 ground colour is almost uniform olive brown. In my vioriia, which Prof. 

 Smith refers to Hulstii, this is replaced, except in costal region and 

 terminal area, by ochreous. 



156. If.(X.Ji:ertvana,Sm\ih.- — Seldom common. June and early July; 

 at treacle. Described from Calgary. The type is at Washington. Dr. Dyar 

 treats this as a variety of European basilinea, Fabr., but Prof. Smith has 

 examined a good series of both forms, as well as oifinitima, Gr., and whilst 

 believing them all three to be distinst, claims that cerivana is nearer to 

 finitima than either is to basilinea (Can. Ent., XXXV., 134, May, 1903). 

 My only finitima is a V from N. Y., and differs widely from the Calgary 

 species, both in colour and in the entire absence of grayish suffusion. A 

 figure is given with the description. 



157. H. (X.) lateritia, Hbn. — Has been a bad treacle pest in some 

 years. June and July. 



158. H. (X.) dubitans, Walk. — Rare on the whole. July. By some 

 peculiar error which I have never satisfactorily explained, I had for some 

 years ff. Alberta standing under this name, or rather under sputatrix. 

 This mistake was certainly not Prof Smith's, and the species are quite 

 dissimilar. Meanwhile my dubitans did duty for Helotropha reniformis,  

 a species of which I have no Alberta record. I probably often used to 

 send out dubitans and Alberta under such erroneous names, but was 

 never corrected ! 



159. H. (X.) impulsa, On. — Very rare. July. A black species, 

 which at first sight might be mistaken for Mamestra assimilis without the 

 white spot near anal angle. 



160. H. (X.J devastatrix, Brace. — One of the commonest Noctuidaj, 

 and a bad pest at treacle. Met with commonly under bark on dead trees, 

 etc., and in outbuildings. End June to August. Have a fair specimen 

 dated Sept. 8th. I know of no species which has so often " fooled " me 

 pn th^ treacled posts, by looking like something new, and what is more, I
