band vermilion red, pale in the incisures ; segments white dotted 

 posteriorly; wart iii bright red at base, the subventral warts pale Hair 

 stiff, reddish subventrally." Our Canadian form ought to be bred to see 

 if the larvae agree with those studied by Dr. Dyar. Doubtless the species 

 will have to be gone over several times before we can get a true 

 knowledge of its variations. 



Distributio?i. — -Aweme, Man. (Griddle). 



12. Nevadensis, var, incorrupta. — This is another Arctian which 

 we did not know occurred in Canada. It also has been found in the 

 West, the only specimens we know of having been collected at Calgary, 

 Alta., and Aweme, Man. The lo examples we have examined (7 c? , 3 ? ) 

 are very similar in markings and do not show any variation other than 

 that appearing on the accompanying plate. The moth is an attractive 

 one, the colour of the secondaries of all the specimens being almost a 

 poppy-red, or rose vermilion. The colour of the abdomen above is the 

 same as that of the hind wings, excepting at the tip, where it is a cream 

 colour, as is also the ventral surface, excepting in the 3 9 and i ^ which 

 have the under surface of the abdomen black with the posterior edge of 

 each segment ringed with white. A dorsal and a lateral row of black 

 spots occur on all the specimens, and in those which have the segments 

 drawn closely together these appear as wide bands. A single 9 Arctian 

 (collected June 28) received from Mr. Wolley-Dod, with the primaries 

 marked as in incomipta, had pure black secondaries, as well as a black 

 body. I do not know of anything having been published on the earlier 

 stages of iiicorrtipta, and any information on the life-history would be 

 very welcome. Dr. Dyar, in his description of the larva of superba, as 

 hereafter mentioned, stated that he thought this to be that of mcorncpta. 

 This shows that much work is to be done yet before we can acquire 

 definite knowledge. Mr. Coquillett describes the larva -of ^V'^e/afl'^^^/.r as 

 black, with a broken, dull white dorsal line, warts gray, the hairs varying 

 in colour (mixed black and reddish or black and yellowish).

13. Superba. — The only examples of this form, which we have seen 

 were collected on Vancouver Island. In the " Bulletin of the Natural 

 History Society of British Columbia," 1893, i^ ^ I'^t, by Mr. W. H. Danby, 

 of Lepidoptera collected in British Columbia, and in this list superba is
