3. IMiCHAUo. — This species must be very rare in Canada, as we have 

 records of only four specimens having been taken. A coloured figure of 

 the moth is given on plate XLVIII. of Hampson's recent " Catalogue of 

 the Lepidoptera Phalajnre in the British Museum." Not having seen a 

 good series of this species, I take the liberty of quoting from Dr. Dyar 

 (Jour. N. Y. Ent. Soc, Vol. VIII., p. 36, as follows : " Michabo is a 

 peculiar form, in markings close to virgo, but in colour so near arge that 

 the two are liable to be confused, and have been so in some collections. 

 It is a simpler form than arge^ the bands retaining their usual shape, only 



the inner one being occasionally somewhat tooth-like " 



" The larva doubtless hibernates full-grown. No description is extant, but 

 fortunately I have a blown larva before me from the Riley collection, as 

 well as cast skins from the Department of Agriculture, and some notes 

 (Dept. Agr. No. 2588). The larva is grayish black, head black, the body 

 rather grayish brown, with a broad, distinct, straight, cream-coloured dorsal 

 stripe. Hair rather long and, though coarse, somewhat soft and brownish. 

 Spiracles white. The notes add a more or less interrupted white subdorsal 

 line, but it does not show in the blown or alcoholic specimens nor in the 

 cast skins. The larva is a close ally oi arge, but differs in the absence (or 

 reduction) of the subdorsal lines. The full life-history is needed." 



Distribution. — Grand Forks, B. C, June (H. Brainerd). This specimen 

 is in the collection of Mr. A. F. Winn, of Montreal, who kindly gave me the 

 particulars. Calgary, Alta., June 9 (WoUey-Dod); Aweme, Man. (Criddle). 



Michabo, var. minea. — A single specimen of the variety, which has 

 been so identified by Dr. Dyar, was sent from Osoyoos, B. C, to Dr. 

 Fletcher by Mr. C. deBlois Green. 



4. Parthenice is by no means uncommon. The moths appear 

 usually in late July and August, generally about the middle of the latter 

 month. Small specimens of virgo are often confused with parthenice, but 

 the former s[)ecies can readily be distinguished by the broad lining of the 

 median vein, and the two, or more, discal spots of the secondaries. Par- 

 thejiice has but one discoidal spot. I have never seen the larva of this 

 moth. Saunders describes it as black, with a flesh-coloured dorsal stripe, 

 tubercles yellowish, bearing tufts of stiff hairs which are black on the dorsum 

 and brown on the sides, and feet and prolegs yellowish, tipped with black
