LYCAENINAE: IIIE (iENUS ERORA. 815 



ImttiM-riy In- Mr. Liutiier at lictlilchciii, N. Y.. on June 22, and at Centre 

 on Julv ; and by Mr. Sprague at West Roxbtny, Mass., on July 3. In 

 the south tlie only dates of capture are those of" Gosse in Alabama, July 1, 

 and Abbot, who bred the butterfly on May 5, after seventeen days in the 

 chrysalis, and records a capture on iNIay 2(i. 



Desiderata. Thanks mainly to Mr. Saunders, our history of this spe- 

 cies is nearly perfect : but we still need a fuller account of the larval 

 stages, and especially of the variation which doubtless occurs ; for Mr. 

 Saunders's description of the mature larva differs remarkably, as he has 

 pointed out, from Abbot's illustrations. The food plant Eupatorium is 

 properlv cliallengcd and should be inquired into by practical ap|)lications 

 to the caterpillar. Tlic details given above concerning the apparition of 

 the imago are based on scanty material, and the reason for its long flight- 

 time (nearly three months) should be explained. The distribution of the 

 insect in the southern and western states, and thi'ough the central portions 

 of New England is very little known, and we altogether lack any report 

 upon its flight, postures and parasites.
