1'74 tilt CANADIAN ilNTOMOLOGISt. 



claviform thickly outlined with black, and hind margin and s. t. space 

 rather contrastingly pale compared with the rest of the wing. Judging 

 from a recent letter to me, Sir George Hampson seems to have confused 

 some specimens of this form which I sent him with Dodii^ which has 

 something of the same range of variation, some specimens showing very 

 much the same contrasts, but always much redder. I am not always 

 sure of unset specimens, but no forms oi lilac ina and Dodii which I have 

 seen are really alike. In fact, lilacina, in having less of the rusty-red, a 

 more direct s. t. line, and an occasional tendency to develop a basal 

 streak, is really a good deal more like rugosa. Prof. Smith has repeatedly 

 seen both forms of my lilacina^ and I have specimens of each bearing his 

 own label. The specimen figured in Dr. Holland's book is about inter- 

 mediate between the two extremes. 



311. M. acidermina, Smith. — (Can.Ent., XXXVI. , 153, June, 1904). 

 Described from ^ ^ $ and 2 $ ?, partly Calgary material; the rest 

 from Cartwright, Man.; B. C., and S. Dak. A $ co-type and five other 

 specimens are in my collection. Very rare, and only taken during 1893 

 and 1899. End June to middle July. Its'author states: "Related to 

 Goodellii in general character ; but is smaller, darker, the maculation 

 barely traceable, and the apex of the primaries distinctly better marked." 

 Until recently I had this species standing as Goodellii. The type is a 

 Calgary specimen and is at Rutger's College. 



312. M. obscura, Smith. — Sometimes very common at treacle in June. 

 This species was formerly sent out by me in considerable numbers as 

 Hillia crasis, under which name Prof. Smith had placed the form in his 

 own collection. The species varies from a dark, reddish-brown to almost 

 black, but always with a reddish tinge. The vigilans form of crasis is 

 somewhat of the same colour, but though there is a similarity in general 

 type of maculation between the two species, they are not really alike. I 

 obtained ova of ^(^.f<:«rrt in 1894. The larvae hatched on June 30th, and 

 fed on Anemone patens. They had all pupated but two on Sept. 3rd. I 

 have no further notes. 



313. M. ectrapela, Smith. — Described from a $ taken by Mr. T. E. 

 Bean at Agnes Lake, near Laggan, Alta. (B. C. in error), 6,800 feet, on 

 Aug. 2 1 St, and from a $ taken at 6,000 feet in Garfield Co., Colorado, by 

 iMr. Bruce. The description tells us : " The species has the wing form of 

 ectypa, and the same general type of maculation, but is of a somewhat 

 bordid dull brown." The type is at Washington.
