bear some extra long slender hairs as before. Venter much paler than 

 dorsum, of a greenish-brown tinge. Thoracic feet shiny black ; prolegs 

 concolorous with venter. 



Stage VI. — Length 17 mm. Head 1.4 to 1.6 mm. wide, subquadrate, 

 slightly depressed at vertex; black, shiny; epistoma pale; mouth-parts 

 reddish; setip black and slender; cheek above ocelli pale brownish, 

 mottled with darker brown. Skin of body velvety black on dorsum, gray- 

 ish-green ventrally. No markings on the body. Tubercles black; bristles 

 from i., ii., iii. and iv. black, those from v. and lower tubercles pale rust- 

 red ; bristles faintly barbed. Some long, slender bristles from dorsum of 

 two posterior segments as before. Thoracic feet black, shiny; prolegs 

 reddish. Larvse do not vary. 



On tlie 3rd September 21 specimens were living, and as they were not 

 feeding very much and looked unhealthy, they were put outside. Later, 

 when they were examined (25ih Oct.), every specimen was found to have 

 died. Mr. Cockle retained some of the eggs himself, but he has since told 

 us that his larvae also suffered a similar fate. Possibly during the coming 

 season eggs may again be secured and more successful results obtained. 

 Mr. Cockle states that the moths are rare at Kaslo. 



Distribiiiion. — Specimens of orjiata have been taken at Osoyoos, B. 

 C. (C. de B. Green) ; Kaslo, B. C, June 30, July 2 (Cockle) ; of the form 

 achaia at Osoyoos, B. C. (Green) ; Kaslo, B. C, July 25, 26 (Cockle) ; of 

 the form ochracea at Kaslo, B. C, June 8 (Cockle) ; Victoria, B. C. 

 (Fletcher), June 7, July 17 (Anderson). 



8. Arge is well known, and rather widely distributed in the eastern 

 part of Canada, though I do not think it can, with us, be considered a 

 common species. It seems to be double-brooded. We have no records 

 of any specimens having been taken west of the Province of Ontario. An 

 interesting account of the species has been recently published by Dr. 

 Seifert,* accompanied by an excellent plate showing the variation in the 

 imagoes. The mature larva measures nearly i^ inches in length, and is 

 grayish black, overlaid, especially on the dorsum, with patches of velvety 

 black. The dorsal and subdorsal bands are cream colour, shaded with 

 pink, and are wide and very distinct. The infra-stigmatal band is nearly 

 the same colour, but is waved and broken, and not nearly so distinct. 

 The tubercles are dull blackish, not polished. The bristles are faintly 

 barbed and rather long, brownish or gray, excepting those from lower
