F. W. Putnam, who has studied the habits of this moth consid- 

 erably, were found to be Harris's species. 



May IGth, I noticed this caterpillar on the apple, and also the 

 pear and cherry, perforating the half expanded leaf and flower- 

 buds. They were very abundant on these buds, and afterwards, 

 when the leaves had partially expanded, they had folded the 

 leaf. It seems to hatch out about the time that the canker- 

 worms and American tent caterpillars leave their eggs, that is, 

 about the first day of May, when the buds unfold. The last of 

 May and the first week of June they were swarming in orchards 

 throughout Essex County, many persons noticing their attacks ; 

 and it seems to be a common insect all over the State. When 

 fully grown, it crumples tlie leaves, disfiguring the whole tree, 

 and doing great damage to the fruit-buds and flowers, thus di- 

 rectly lessening the apple and pear crop. About the first of 

 June they cease eating, and make a loose, delicate silken cocoon 

 in the folded leaf. They remain several days — sometimes near- 

 ly two weeks — in this state, before assuming the chrysalis state, 

 which, as Mr. Putnam observed, occurred June 16, and the 

 moths are seen flying about and entering houses, attracted by 

 the light within, during the last week of June and the first of 

 July. The chrysalis is brown and of the usual shape, and, as 

 Harris states, has but a single row of teeth along the dorsal side 

 of each abdominal segment. After the moth has slipped out of 

 the pupa case, the empty shell remains attached by the tip of 

 the abdomen to the surface of the leaf. 



The moth is closely allied to the Grapholitha cynosbatella, 

 (G. ocellana,^ of Europe. The body is dark ash color, the fore 

 wings being usually paler in the middle. The basal third of 

 the wing is dark ash mottled with paler scales, the outer edge 

 of the dark area being angulated just behind the middle of the 

 wing. The costa is marked with light and dark bands. On 

 the outer third the wing is nearly as dark as on the base ; near 

 the outer edge, and half way between the costa and hind edge, 

 are four well-marked longitudinal black spots, or short lines 

 running parallel with the costa, or front edge, of the wing ; the 

 one nearest the costa is simply an elongated dot, the second and 

 largest is an oblong spot and twice as wide as the third spot, 

 while the fourth again is much smaller. There are three sim-
