274 THE BUTTERFLIES OF THE 



but differs in having the outer part of the hind wings 

 somewhat rust-colored, the teeth shorter, and the first one 

 beyond the anal angle not curving outward, and in want- 

 ing the black spots on the under side of the hind wings 

 between the bases of the first two teeth. The stigma on 

 the fore wings of the males is shorter and wider, being 

 only twice as long as wide. It averages smaller than 

 var. Arsace. 



According to Mr. Edwards, the eggs are deposited on 

 wild plums at the base of the flower-stalks. When 

 the young larvae hatch from the eggs they ascend the 

 flower-stalks and eat the newly-forming fruit. A hole 

 is eaten into the fruit large enough for the head to 

 enter, and thenceforward the caterpillar spends most of 

 his time with his head in the cavity, growing with the 

 growth of the plum, until the whole interior is eaten 

 out. 



The eggs are shaped like those of Lyccena Violacea, 

 flattened and depressed : about this depression the ridges 

 are reduced, and the surface is finely reticulated, but 

 elsewhere there is a white frosting of peaks and ridges. 

 Color whitish green. The lace- work seems to be sepa- 

 rable : in one case where the egg had been rubbed by 

 a leaf, apparently, a film was turned up, and the real 

 surface was seen to be delicate green. 



In from five to six days the larva hatches. Length 

 .04 of an inch, oval, broadest anteriorly, the base 

 flattened ; dorsum high, sloping posteriorly ; summit a 

 little flattened, with two rows of long, recurved white 

 hairs on each side. Color brownish yellow. 



Five days afterwards it moults the first time, when it is 

 .08 of an inch long, with a red-brown dorsal stripe stop-
