THE CANADIAN ENTOMOLOGIST. 275 



England, pi. 64, fig. 2. Slightly widest at one-third from base. Ribs 

 about 22-24, well marked, but not very prominent, and with many cross 

 ribs, as in Scudder's figure of that of Satyrus Alope, fig. 3 on the same 

 plate. 



Young Larva. — Head large, pale brownish, pitted with many small 

 depressions, which are darker, and ornamented with a number of brown 

 spots, which are arranged as follows : four on the summit, two near 

 together towards the front, and two further apart behind, below these a 

 row of six, and a few minute ones lower down ; the ocelli black. 



Body. — Length, 2.5 mm.; pale in colour, with a dorsal, three sub- 

 dorsal, a lateral, and a subspiracular stripe of brown. Second segment 

 has about ten minute tubercles in a row, some smaller than others, and 

 one on each side in the subdorsal region in advance of the row. On 

 each segment, f rom 3rd to 12th, inclusive, there are six small tubercles 

 above, arranged •' | '.• ,and also several smaller ones on each side rather 

 low down. All the segments except 2nd and 13th are divided by three 

 transverse wrinkles. 



On loth several were seen to be swollen for first moult, but others 

 continued to feed. On 12th ten were counted, and all but one seemed 

 ready for first moult. In the evening one was seen to have passed the 

 moult, several more passed on the 13th, and by the 14th all in sight had 

 passed the moult, the average length of first stage being thus nine days. 



After First Moult. — Length, 4.7 mm. Head rather large, exceeding 

 the 2nd segment, brownish-green. Body tapering pretty evenly to anal 

 extremity, which now terminates in two blunt points, as stated and figured 

 by Edwards. The head is pitted as before and covered with clubbed 

 tubercles. The body tubercles are very numerous, 'short, curved towards 

 tail, and slightly clubbed. Towards the tail they get longer and are hardly 

 clubbed. I could not discern any difference between those on the 2nd 

 and 3rd segments. The tubercles are translucent brownish-green or pale 

 in colour, and spring from brown spots. Body pale yellowish with a 

 tinge of green. There is a dorsal stripe of dark brown, and a subdorsal 

 and two lateral brown stripes, the lower being just above the spiracles. 

 The next one above is wider than the others and diffuse on lower side. 

 Spiracles are dark brown or black. The basal ridge is yellowish, and 

 below it there is on the 5th to 12th segments, inclusive, a brown oblong 

 spot, described by Edwards as a continuous stripe. Venter and prop- 

 legs brownish-green, speckled with brown dots ; feet greenish.
