increase, and every proper means should, therefore, immediately upon 

 its discovery, be resorted to, that its spread may be arrested. 



The parent is a small moth (shown at c, much enlarged) belonging 

 to the Tineidce — that division of the Lepidoptera that embraces the 

 smallest species of the order. There are two annual broods of the 

 insect. The cocoons sent to me are of each brood. Some of them 

 were spun in July, and have given out the insect, leaving only the 

 empty pupa-case within the cocoon. The moths that emerged from 

 them laid eggs from which the caterpillars were hatched, which 

 might have been observed feeding upon the leaves in September, if 

 attention had been given at the time to the eaten foliage. The cater- 

 pillars make their cocoons during October, and upon opening those 

 that are the freshest-looking and unbroken, the pupae may be found 

 which are destined, if not meanwhile destroyed through parasitic or 

 atmospheric agency, to remain in that state throughout the winter, 

 and to give out the moth in the month of May next. 



A notice of this insect, containing further information upon it, may 

 be found in my " First Annual Report on the Insects of New York, 

 1882, pages 157-162." 



Distribution. 



In the above publication, the presence of this insect had only been 

 reported within the State of New York, in Monroe and Chemung 

 counties. As would naturally be expected, it seems to be extending 

 its range. It has since been received by me, from an orchard of Mr. 

 J. S. Roy, Lyons, Wayne county. A piece of twig only two and one- 

 half inches long contained twenty-two of the cocoons. It has also 

 been sent to me by Mr. J. C. "Wolf, of "Waterloo, Seneca county. It is 

 reported as present, in small numbers as yet, in Lagrange, Wyoming 

 county. It also occurs in South Byron, Genesee county. 



I had previously written of this insect, that as yet in its New York 

 distribution, it was apparently confined to the western portion of the 

 State, but the present year it has been brought to me from an orchard 

 at Bethlehem Centre, five miles south of Albany, on the Hudson river. 

 Mr. Isaac Bussing, with whom it occurred, reports that he has observed 

 it upon his trees for the past few years, in limited numbers, but does 

 not think that it inflicted serious harm. 



In the Second Report of the Department of Entomology of the Cornell 

 University Experiment Station, 1883, Mr. A. E. Brunn has published his 

 studies upon the life-history of this insect (with illustrations of some 

 of its stages) which adds materially to our previous knowledge of it 

 (I. c, pp. 157-161, pi. 6, figs. 2-2 e). An abstract of the above observa-
