ing in that state in 1837. Since its original description it has been 

 noted in various lists and papers, notably by Fitch (loc. cit.), by 

 Saunders (Can. Ent., Vol. 2, p. 6, 1869) '(Can. Ent., Vol. 3, p. 76, 

 1871), who studied it in Ontario, Canada, and by Smith (Brook. Bui., 

 IV, p. 28, 1881). 



The insect is apparently confined to the eastern part of North 

 America ranging from Canada south through the Atlantic States. 

 Saunders records it from Ontario in July. Winn records it from 

 Montreal and other places in Quebec, July, August (Prel. List Ins. 

 Quebec Lep.) ; Dyar's. List gives Atlantic States and Smith (Ins. 

 N. J.) throughout New Jersey, July, August. In the latter state 

 where our own observations have been made, we have collected it in 

 a number of localities from mid July until mid August. We have, 

 also collected it in Connecticut and Mr. W. T. Davis records it from 

 Staten Island in July and August. 



The larva destroys or injures many blossoms by its characteristic 

 feeding habit of "boring a round hole in the bud" of sufficient size 

 to admit its head which it sinks downward farther and farther, eating 

 through the folded mass of petals, nearly or quite cutting them 

 asunder and severing also the stamens and pistil." Thus when the 

 flower comes to burst forth from its bud at the close of the day, it 

 is but half its normal size and presents a most rueful aspect with 

 the outer end of its petals gnawed and ragged, and all the beauty of 

 their natural appearance destroyed." (Fitch, I. c). Foliage may 

 also be eaten to a slight extent. 



The following descriptions of the different stages and life history 

 notes have been taken from the papers already referred to and from 

 our own observations in the field. 



Egg.— "Length one fortieth of an inch; width one forty-fifth. 

 Form nearly round, flattened a little at the base, where it is also 

 somewhat contracted in size, and slightly conical above, with numer- 

 ous raised strias, about 36 in all, which run into each other before 

 they reach the tip, where they are reduced to less than half the 

 number, and terminate at the base of a small ring which crowns 

 the tip: this ring has a depression in the center, and the space around 

 the cavity is finely punctured. The striae are irregularly crossed 

 by numerous fine, raised lines, and thus the whole surface is mi- 

 nutely reticulated, but the meshes are irregular in form, with a
