1616 THE BUTTERFLIES OF NEW ENGLAND. 



Denison, Iowa (Allen) and the Yellowstone region and Montana 

 (Edwards). Farther south it has not been taken west of eastern Kansas 

 {Snow) and Nebraska (Dodge). 



In New England it has only been taken in a few localities in rather 

 scanty numbers — at Holyoke (Chase), Amherst and Mount Tom (Dim- 

 mock), Belchertown, Granby and Montague (Sprague) and Springfield, 

 Mass. (Emery), at New Britain, Conn. (Dimmock), and in Rhode 

 Island. 



Life history. In the north there is but a single generation, but in the 

 south it is probably double, perhaps triple brooded, and can hardly winter 

 there as a chrysalis — rather as a caterpillar. In the north it seems to appear 

 upon the wing early in July, occasionally by the very last of June, and to 

 fly until the middle of August. Abbot reports the capture of a specimen 

 in Georgia on the 2d August, probably corresponding to this single north- 

 ern brood ; but it was taken in consideralile numbers in Apalachicola, 

 Ela. , by Dr. Chapman, as late as the 1st of October. 



Abbot says it inhabits oak woods in Georgia, which Judge Chapman 

 speaks of as the best collecting ground in Florida, but in Iowa Mr. Allen 

 found it on the flowers of Echinacea angustifolia D. C, which grows on 

 grassy knolls of the open prairie. Mr. F. H. Sprague found it in the Con- 

 necticut valley alighting in the roads near meadows and Jirooks ; according to 

 liim it is "terribly shy" and difficult of capture, not allowing approach. Dr. 

 Chapman finds the food plant of the caterpillar to be Erianthus alope- 

 curoides Ell. — one of the Gramineae. 



Desiderata. The number of broods of this insect in the south, and its 

 general history both north and south are the points which most require in- 

 vestigation. We have no description of its earliest stages, nor have we 

 any account of the flight, postures and habits of the imago — in short nearly 

 every fact is desirable.
