216 Fiftieth Keport on the State Museum 



It may be distinguished from F. cvscuiana by the following characters, 



according to its describer : 



Claypoliana lacks the notch in posterior borders of primaries, the tufts 

 of I'aised scales on the discs of same, and the peculiar tuft or pencil of 

 hairs on the upper surface of secondaries in the male, between the 

 margin and the costal vein. It is a shorter, broader-winged species; 

 the ocellate spot is less distinctly relieved, the median oblique band more 

 broken, the basal-costal portion paler and contrasted along the median 

 vein with a dark shade which may be almost black, and which broadens 

 posteriorly till near the middle of wing, where it is abruptly relieved by 

 a pale space obliquing basally. 



Description of Several Stages. 



The moth has been characterized briefly by Prof. Claypole as follows : 

 " It was small, with a peculiar hopping flight, the fore wing mottled 

 black and white, and the hind wing more uniform in color, dusky, and 

 slightly spotted with black near the tip." 



The light red pupa was inclosed in a rolled up leaf lined inside with 

 silk. Eight abdominal segments were visible. 



A larva examined May 13th was two-fifths of an inch long with a 

 yellow head and yellowish body. The minute granulations of the skin 

 are smooth, — not pointed as in P. ccsadana. The same general appear- 

 ance was retained until pupation, except that it became a little darker. 



Operations and Life-History. 



In the leaf-stalks of the buckeye, .-Esculus glabra. Prof. Claypole 

 found the insect during the early part of May. About the loth, they 

 deserted the petioles through the holes by which they had entered, 

 and betook themselves to the fading leaves. Upon the dying foliage 

 they completed their growth naturally to all appearances. This food- 

 habit is apparently normal, as no nibbled green leaves were found on 

 the infested trees after the larvae had deserted the leaf-stalks. Pupation 

 occurs the latter part of May,— the first pupa being found on the 25th. 

 The moth appears about fifteen days later. Prof. Claypole was not 

 able to ascertain the place and manner of the deposit of its eggs, the 

 number of broods, or the form in which it hibernates. 



The work of this insect in the maple leaves coincides closely with that 

 in the buckeye. The egg of the parent moth appears to be placed at 

 the base of the leaf, — perhaps at the divarication of the ribs. As the 

 young larva tunnels the petiole, the portion traversed by it shrivels, black- 

 ens, dries, and is broken off by the weight of the leaf. The larva con-
