132 STEROPES PANISCUS. 



or rather, I should say, that in attempting to tear away 

 a small strip from the tube the larva took fright and 

 leaped nimbly out of it, then remaining, without a 

 movement, perfectly still for nearly two hours. It was 

 of a green colour, very soft and velvety-looking, the 

 lines on the body as above described ; the head dark 

 green, marked with black on each lobe and between 

 them on the crown, a black spot on each side of the 

 face, ocelli black ; on the very short second segment 

 is a black transverse mark in the middle and a black 

 spot close outside the subdorsal line, and another 

 smaller lower down; these are the development of 

 the former linear plate ; the anal segment is very pale 

 green, with a dorsal mark of black on the flap. The 

 subdorsal line is the palest and is well relieved above 

 and below by the darkish full green, which it runs 

 through; beneath this are two extremely faint fine 

 paler lines, only just perceptible. The length at this 

 time was 6 J lines. The general green colour is a trifle 

 deeper than that of Pamjphila linea. 



On the 18th of August I saw a larva two -thirds of 

 an inch long and very slender, commencing to make a 

 new tube for itself. On the 24th I saw a larva in the 

 act of leaving its case, after all the leaf at either end 

 had been eaten away to the midrib, by which alone it 

 was supported. I cut it off and then figured it with 

 the larva upon it, deliberately advancing towards the 

 stalk to find another leaf to construct a fresh dwelling. 

 This larva measured exactly 9 lines long and was in 

 all details as above described, except that the remains 

 of the black linear plate on the second segment were 

 now only a dorsal spot and a fine dot well below the 

 subdorsal region. The anal flap was a trifle concave on 

 its surface, tapering to a rounded-off point beyond the 

 anal prolegs ; it bore a broadish black dorsal rough 

 stripe. The segments behind the thoracic were all sub- 

 divided by transverse wrinkles into five rings, of which 

 the first ring was the widest, the second nearly as wide, 

 and the other three very much narrower.
