THE CANADIAN ENTOMOLOGIST. 107 



anterior parts streaked with fine, abbreviated, brown lines ; on the mar- 

 gins of the wing cases a series of dark brown spots ; beneath the abdo- 

 men two brown stripes, and on the middle of each side a row of brown 

 points extending from the mesonotum to extremity. Duration of this 

 stage 1 1 days. 



Eurytris is a common species in this section of West Virginia, found 

 in the borders of the forest and in the adjacent fields, especially if these 

 last are more or less overgrown with brambles, &c. The eggs are easily 

 obtained by confining the female in a box, or over a flower pot in which a 

 bit of sod has been placed. They are laid upon the grass, or dropped 

 loosely upon the sod or the earth. The first eggs so obtained by me were 

 laid 30th May. The earlier stages were rapidly passed, as related above, 

 but the last were very much prolonged. About 20th July, soon after the 

 third moult, the larvae all ceased feeding, and some appeared to be in pro- 

 found lethargy. But others, after resting for several days, would arouse 

 and eat a little, then sleep again. But every one, notwithstanding the 

 lethargic condition, was found to have changed its position several times. 

 After keeping them so two weeks, I left home for some months, and on 

 my return found all were dead. But one larva that I had sent to Miss 

 Peart before 20th July went on to imago, and I inferred that probably 

 some of the others would have done so after sleeping for an interval, had 

 I been at hand to feed them. This was in 1876. In 1S77 I raised a 

 small brood from eggs obtained 31st May. With these every stage of the 

 larvae, after the first, lingered. When about to moult the larva remained 

 for three or four days before this event motionless, and as many after, and 

 there were periods of several days between the moults when they rested 

 and took no food. As I kept them in small glasses it was easy to deter- 

 mine this. The larva is sluggish at all times, moves very little and with 

 great deliberation. Part of this brood at last ceased feeding altogether 

 and contracted themselves for a long sleep. But I eventually lost all but 

 one of these, probably from the heat of the weather, as one after another 

 dropped off its support, dead. The single larva spoken of continued to 

 feed and reached the length of about one inch, when winter set in, and 1 

 then set it in a cold room to preserve it till spring. By an accident this 

 one was lost in January. It appeared to be healthy up to this time, and 

 the imago would probably have emerged from chrysalis in early spring. It 

 will be seen that breeding these larvre is an excessively tedious matter, 

 requiring months to perfect, and involving many risks. As fresh butterflies
