side, and of the wing cases, blackish-brown, as is also the process ; 

 abdomen light-buff with a pink tint, mottled with olive-green, less so on the 

 dorsal side ; the end segments dark-brown; dorsal side of head-case and 

 the mesonotum pale brown, the head-case obscurely silvered. I got but 

 one pupa, and that died before imago, and of this Mrs. Peart made a 

 coloured drawing. Only one larva went through all the stages, the 

 others, after second moult, made cases, just as the allied species do, and 

 I have them here, out in the weather, under a net to protect them from 

 birds. The larvae hatched 28th August ; passed first moult ist September, 

 second moult 4th ; one passes fourth moult 13th Sept., pupates iSth.*

This small species belongs to Group II. of my Catalogue, 1884, and 

 its nearest ally on this continent is A, Bellona, Fabr. It flies in the 

 Pacific States and to and through the Rockies. On 7th July, 1890, I 

 received several eggs from Mr. Koebele at Spokane, Washn., and they 

 were hatching on arrival. The larvae passed first moult on nth July : 

 second, 15th; third on 19th, and within two days thereafter all except 

 one became lethargic after third moult, and before 27th July. The one 

 passed its fourth 7th August, and was sent to Professor Riley for a 

 drawing. It pupated while in his care, but I have not the date. The 

 imago came out at Washington. Excellent coloured drawings were 

 made of the adult larva and pupa. I attempted to carry the hibernating 

 larvae through the winter at Coalburgh, but they one by one died, the last 

 about middle of February. The food plant was violet. The larva at 

 birth resembled closely those of Bellona and Freya (which last I had 

 feeding at same time), the segments 5, 7, 9, 11 being brown, as in those 

 species, while the rest of the body was pale green. After first moult? 

 length .14 inch : colour greenish-brown over upper part, greenish beneath ; 

 the spines short, stout, tapering, black ; those on 2 no longer than in 

 following segments. 



At second moult, .24 inch \ colour of dorsum black, with a pair of 

 mid-dorsal gray lines ; the sides mottled dull white and green ; along 

 base a narrow sordid white stripe from end to end ; all the spines black, 

 but in the dorsal rows, at bases of 2, 6, 8, 10, on outside, tubercle is 

 pale, obscurely whitish. 



* I am able to say, on revising these proofs, that I got two of the larvse through 

 h^ winter. One has passed two moults since waking up, the other still sleeps,
