Eighth Report of the Stave Entouoloqtst. \'M) 



The Moth. 



The moth is so well shown in Figure 2, thai it can hardly fail of 

 recognition when the comparison is made, but, as of possible service to 

 the student, the original description by Mr, Chambers is transcribed: 



Head white; tuft tipped with dark reddish-brown, and the face 

 faintly tinged with purplish fuscous. Upper surface of the thorax 

 brown margined by white. liast> of the fore-wings white, followed by 

 an oblique brown fascia, which is nearest the base on the costal margin, and 

 is followed by an oblique parallel white fascia; all of these are placed 

 before the middle 1 , and are followed by a large brown patch which occu- 

 pies the entire wing to the cilia' [cilia], except that it contains a white 

 Spot on the middle of the costal margin; the brown patch is margined 

 before on the dorsal margin of the wing by a small tuft of raised 

 brown seal- s; at the beginning of the dorsal cilia 1 is a white spot placed 

 a little before, but becomes almost confluent with a longer white costal 

 streak; behind these streaks to the apex of the wing is pale brown, 

 with a darker velvety brown apical spot; cilia' pale yellowish, with a 

 dark brown hinder marginal line before their middle, not extending to 

 the costal cilia 1 . Expanse of wings, three-eighths of an inch. — From 

 Canada. 



Mr. Fletcher's description of the fore-wings will give a better idea 

 of their general appearance: 



Wings crossed with silvery white bars; three of these run from the 

 outer edge about half way across the wings obliquely toward the apex, 

 and there are two shorter subtriangular blotches on the inner margin of 

 each fore- wing. These latter, when the wangs are closed, form two 

 white dorsal saddles, the anterior of which is slightly the larger and is 

 followed closely by a tuft of raised black scales. At the extremity of 

 the fore-wings are also several raised black scales, a few of which are 

 separated into an apical spot by an irregular narrow white band. The 

 cilia of the fringes are pale brown. 



Life-history and Habits. 



The life-history of this insect is as yet unknown. Neither the eggs 

 of the moth or the mining operations of the larvae have been observed. 

 The following seems to be about all that is known of the insect: 



Larva? had built their cocoons at Ausable Forks, N. Y., on September 

 8, 1886. Of examples received from Monroe county, N. Y., on Septem- 

 ber fourteenth, a few had already made their cocoons, and the follow- 

 ing day nearly all had completed or commenced their construction. 

 The larva eats the parenchyma out of both sides of the leaf. In con- 

 finement it walks slowly, often dropping down and hanging by a thread. 

 The first Aveek in September larva 1 were seen within' their molting 

 cocoons, and previous to that had been noticed feeding exposed and 

 eating little holes in the upper surface of the leaves, at Brunswick, Me.
