amount of cutting at its base gives the requisite size and desired 

 form. 



Resting upon the inside of this recurved portion, the larva may 

 always be found, except during the brief time that it leaves its con 

 cealment to take its food from some neighboring leaf. Its rapid 

 feeding soon satisfies its appetite, when it moves quickly back and 

 resumes its position. In localities where the larva occurs, these 

 hiding-places may be readily found by bending over the stems of the 

 Aquilegia, when these little bits of the bright green upper surface of 

 the leaf, in marked contrast with the grayish-green of the lower side 

 upon which they rest, at once disclose their presence. Should one of 

 them be found deserted, its former occupant may perhaps be dis 

 covered on a leaf near by, within a larger retreat of similar construc 

 tion. From the gradation of sizes observed, it is probable that fol 

 lowing each molting a new shelter is constructed, of a size sufficient 

 to cover the larva during that stage of growth, until at the last larval 

 molting, when an entire leaf is simply folded over, or two or more 

 leaves have to be brought together in order to afford the necessary 

 concealment. 



Some of the larvae taken at this time had undergone their third 

 molt, many their second, and the larger number their first. About 

 one hundred were collected, and two eggs near their development. 



Fresh broods of Argynnis Myrina and A. Bellona were observed 

 on mint blossoms ; also many Ilesperia Peckius, Limenitis muippus 

 and Thymelicus Numitor. Bethlehem. 



July 30th. Limenitis misippus abundant and easily captured. 

 A few Ilesperia Peckius seen. Some Lyccena comyntas in good 

 condition, but L. Scudderii quite worn. A few Thecla Mopsus^ a 

 little worn, on blossoms of Jersey tea. Some P. olercicea, but no 

 P. rapce observed. Center. 



July 31st. The third brood of P. oleraoea quite abundant at 

 Schoharie. 



August 6th. At Saratoga Springs, saw a number of Pieris rapce, 

 in company with P. oleracea, flying about gardens and blossoms of 

 burdock in vacant lots. 



August 8th. At the Glen, Warren county, Pieris rapw was numer 

 ous, and its larvae were found on garden cabbages, usually feeding on the 

 tender central leaves of the plant, unlike oleracea, which more fre 

 quently occur on the older outer leaves. On a small central leaf of 

 a plant commencing to form a head, three larvae were feeding, the
