hue. Immediately behind the head there are two long movable fleshy horns and a 

 number of shorter horns, and orange coloured tubercles on the remaining segments. 

 The eggs are laid by the butterfly, on different species of A ristolochia, chiefly on the Dutch- 

 man's pipe (Aristolochia sipho) and the viginia snake root (Aristolochia serpentaria). The 

 larva} feed in company and when plentiful will sometimes entirely consume the foliage 

 of the plants on which they feed. 



Fig. 1 8 represents the chrysalis of this insect, 

 which is fastened at the hinder extremity to a 

 mass of silken threads and has a band of the 

 same material extending entirely around the 

 chrysalis, beyond the middle. 



In the August number of the Canadian 

 Naturalist and Geologist, for 1858, an account is 

 given by the Rev. C. J. S. Bethune, of the ap- 

 pearance of a very unusual number of these 

 butterflies, in West Flamboro'. The writer says, 

 " these butterflies appeared in countless numbers ^ 

 about the lilac trees, as long as they continued 

 in blossom, and then suddenly disappeared. They lasted 

 June, but very few appearing after that date." He also says, 

 Toronto, though they were numerous there also. 



No such good luck has befallen any entomologist in Ontario since that time. Within 

 these twenty-two years several specimens have been taken about Toronto, and two or three 

 some fifteen years ago at Woodstock. There are no records of the capture of this 

 butterfly here for many years past, but this season a specimen was caught by Mr. J. A. 

 Moffat, at Ridgeway, Ontario.

Juxonia Lavinia (Ccenia). 



The first recorded occurrence of this butterfly in Ontario, is found in the ISTovembe 

 number of the Canadian Journal, for 1861, where an account is given by me of the 

 capture of three specimens, at Port Stanley, two by Mr. Wm. Edwards and one by my- 

 self. During the same season it was found in the townships of Ellis and Logan, about 

 ten miles north of Stratford. For very many years past I have not heard of a single 

 specimen being taken in Ontario, until this season, when it was captured by Mr. Moffat, 

 at Ridgeway, and by Mr. Denton at Port Stanley. 



It is a very pretty insect. The general colour of the upper surface is brown. On 

 the fore wings there is a broad whitish band, extending nearly across the wing and enclos- 

 ing near the hinder angle a large black eye-like spot, with a central bluish dot and 

 encircled by a yellowish brown ring. In some specimens a second and very small spot is 

 situated near the tip outside the band. There are also two smaller, short, red bands 

 bordered between the white band and the base of the wing. 



On the hinder wings there are two conspicuous eye-like spots, the under one much 

 smaller than the upper, and both encircled by a yellowish ring, bordered with black. Between 

 these eye-spots and the hind margin is placed a band of red, margined externally by one 

 or more dark lines. 



The under side is paler than the upper, with the markings less distinct. 



The caterpillar is said by Boisduval to feed on Linaria canadensis. It is black and 

 spinous with two lateral white lines, the upper of which is marked with a row of reddish 

 spots.
