1724 THE BUTTERFLIES OF NEW ENGLAND. 



(Sprague), and Granby, Mass. (Spragiie, Scudder). It has also been 

 found in Uhode Island and in Connecticut — Farmington (Xorton), Oxford 

 Hayes, ^lus. Yale Coll.) and Guilford (Sniythe). 



Life history. The butterfly appears to be single brooded and probably 

 passes the winter as a chrysalis. It makes its appearance in the imago 

 state the very last of June, occasionally as early as the 22d ; by the 7th of 

 July it becomes abundant, and remains on the wing not only through 

 July, but in diminished numbers far into August. Mr. Lintner even took 

 a specimen as late as the 9th of September. The eggs are laid in July — 

 all that I have had about Cambridge between the 14th and 17th — and 

 hatch in about thirteen days. The caterpillars feed readily on ordinary 

 grasses, and their tubular nests are rather loosely constructed of grass 

 blades, in which, however, all the lateral slits are kept from opening by 

 numerous connecting threads between the blades. It takes them about 

 three weeks, sometimes a little more, to pass two moults, and it is not 

 until late in September that they can reach the chrysalis, in which state they 

 probably winter. Like the preceding species the butterfly is found in moist 

 meadows. 



Desiderata. Nothing whatever is known of the later preparatory stages 

 of this insect, and until this lacuna is filled, our knowledge of the buttei-fly 

 must be considered meagre. Whether it winters as a mature caterpillar or 

 as a chrysalis is unknown. It should be sought for in all localities in which 

 it has not been detected, in order to extend our knowledge of its distribu- 

 tion. Only an outline of the probable history of the butterfly is given above, 

 and this needs the confirmation of repeated observation. The flight and 

 postures of the butterfly and the habits of the caterpillar should be studied, 

 and parasites sought. As it has been supposed by some to be identical 

 with the next species, the question of its life history is the more important.
