THE CANADIAN ENTOMOLOGIST. 21 



camp, in the foothills on Sheep Creek, on July i6th, 1898, has been so 

 referred by Prof. Smith, and passed as such by Dr. Barnes. A perfect $ 

 taken at light at the C. P. R. chalet at Lake Louise, Laggan, on July 14th 

 last, I have placed under the same name, thougli I admit it is almost as 

 much like the following species. 



170. H. (X.) sora, Smith.— (Can. Ent., XXXV., 133, May, 1903). 

 Two fine S 6 oi''ly '""^ve been taken. One is the type which is now at 

 Rutgers College, and the other a co-type in my own collection. July 2nd 

 and 15th, 1896; treacle. In general appearance the form suggests $ 

 Barnesii, but is shorter winged and more even in colour than my $ of 

 that species. I had at first looked upon both as probable varieties of 

 Alberta, but they are really more like auranticolor. Neither need be 

 confused with that species, however, which is larger and much more 

 strongly coloured. 



171. H. (X.) semilunata, Gxi. — Always rare. Treacle. June. 



172. H. aliecio, Smith. — Rather rare. At treacle, in September. 

 Described partly from Calgary material. The type is in the U. S. 

 National Museum. According to Prof Smith, this species differs super- 

 ficially from niadaia only in colour, of which allecto lacks the reddish or 

 brown shadings, and is black and gray only. I have examined a number 

 of specimens from both Calgary and Cartwright, Man., but have been 

 unable to procure true niactata for comparison. Some specimens seem to 

 me to have a slight brownish tinge, especially a Cartwright ^ sent me by 

 Dr. Barnes labelled mactata. Mr. Heath, however, has not mactata on 

 his list, and all the allecto he sent me were like the Calgary form. 



173. H. trans/rons, Neum. — Sometimes very common at light and 

 treacle, but, in eleven seasons, I am not aware that amongst the numbers 

 taken by Mr. Hudson and myself, more than two have been 9 9- I iised 

 at one time to send it out as violacea^ with which species I am not 

 familiar. Dr. Ottolengui corrected the error. There is considerable 

 variation in intensity of colour. Li some specimens the s. t. area is con- 

 spicuously white, in others scarcely contrasting. Sometimes the violaceous 



. coburing of central band, and even basal area, is intensely rich, and such 

 specimens are very pretty. July and August. The type is recorded 

 vaguely from " British Columbia," and is in the Museum of the Brooklyn 

 Institute of Arts and Sciences. 



174. H. claudens, Walk. Nearly always a rarity, but some numbers 

 turned up at treacle in 1903, a year favourable to many Hadefias. Middle 

 •August to middle September. .
