')0 THE CANADIAN ENTOMOLOGIST. 



at an altitude of about 5,000 feet. It is, in my experience, rarely found 

 on the mountains, but I took a single male, the past seaon on a mountain 

 ridge, at 7,800 feet, or about 500 feet above the tree line. This specimen 

 does not differ from those of the valley, 3,000 feet below. The form you 

 mention (Briicci), which partly lacks the eye spots, I do not find. 



^'' Epipsodea occurred at McLean, altitude 1,900 feet, in 1884, though 

 not so common as it is at Laggan, and the localities were open grassy 

 flats." 



The eggs sent me by Mr. Bruce, in 1888, were laid by a female of this 

 van Brucei, not wholly destitute of spots, there being two or three black 

 points on fore wings. The outcome was a single male, true type Epipsodea, 

 scarcely banded beneath, out of chrysalis 12th May, 1888. The eggs were 

 laid 8th July and hatched 20th. On 25th, there were seven young larvae. 

 The first one passed first moult 27 th July, the second moult 4th August, the 

 third moult 28th August. The others lingered in their stages, but by 15th 

 September, five had passed third moult. They were at all times kept out 

 of doors, and cool weather now coming on they ceased feeding gradually. 

 On 29th October, I found but three larvae, all in lethargy, two of the five 

 having disappeared. In November, I took them to Clifton Springs, as 

 before stated. On 5th April, 1888, I received them again, two alive and 

 wide awake as I opened the box. These were at once placed on grass, 

 and in five minutes thereafter were feeding. On 15th April, one passed 

 its fourth moult, the other on 17th. On 30th April, I noticed that one 

 was bringing together leaves of the grass and forming a sort of loose 

 cylinder. It was in the middle of a pretty dense tuft, the leaves of which 

 were three to four inches long. On one of these the larva rested, holding 

 by its prolegs, and was spinning a few threads and drawing the leaves 

 down and about it. Before night the inclosure was complete. Nearly a 

 score of leaves were held, mainly by threads at top and bottom, that is, 

 above and below the larva, making a pretty close covering, but open by 

 spaces so that most of the side, and the head, were exposed to view. 

 The larva rested head up, back arched. Mr. Scudder, in But. N. E., has 

 well characterized this structure as " an imperfect cocoon." Pupation 

 took place on the night of ist-2d May. Some hours after, when the 

 chrysalis had hardened, 1 cut away the leaves one by one. There were 

 fifteen of them, and the pupa rested upright, its lower end one and a-half
