A List op the Butterflies of New England. 



BY SAMUEL H. SCUDDER. 



In the following list, I have made mention of every species of 

 diurnal Lepidoptera of which I have seen specimens from New 

 England ; I enumerate eighty-one species ; in the recent edi- 

 tion of Harris's Treatise on Insects injurious to vegetation fifty- 

 four are mentioned ; a portion of this difierence is made up 

 of those of which only a single individual or two have been seen, 

 and are only occasionally found here, being more abundant to 

 the southward ; but there have been added also very many spe- 

 cies which may properly be said to belong to the New England 

 Fauna. Of such as are new, or have been confounded with 

 others distinct from them, or have been incorrectly described, 

 I have given short descriptions ; these are mostly found 

 among the Hesperidae, where also are to be found the prin- 

 cipal additions to the number of our Butterflies in the recent 

 edition of Dr. Harris's Treatise ; whenever names are given 

 different from those used in Harris's Treatise, I have given 

 his as synonyms to avoid any confusion which might arise, 

 and these are the only synonyms I have given, except in 

 those cases where it was evidently necessary (e. g. Hesperia 

 Egeremet). In all cases I have stated to the extent of my 

 knowledge their comparative rarity or abundance, and have 

 frequently mentioned whether they were more abundant in 

 the northern or southern portion of New England. I have 

 endeavored also to place in a succinct form what knowledge 

 of each species we yet possess as to the haunts of the imago, 

 the number of broods each year, their times of appearance, 

 and the food-plant of the larva ; this is given rather to stim- 

 ulate further detailed enquiry by showing the paucity of our 

 knowledge, than as any material addition to what has here- 

 tofore been published ; with the hope that it may render 

 some service in this direction it is offered to the Institute for 

 publication.
