were in the coliection left by the late Mr. Billings, of this city, and which 

 were probably captured in this vicinity. I have also found a ^ among 

 some Hymenoptera sent to me for examination by Mr. Evans, of Trenton, 

 Ont., and'have been informed by Provancher that a specimen (without 

 abdomen) was shown to him some years ago at St. Hyacinthe, Que. 



One female taken in 1883 had the cavity of the abdomen swarming with 

 small mites, which also covered the ventral scale, and were thickly scat- 

 tered along the protruded ovipositor. They appear to belong to species 

 distinct from any yet noticed, although I have found many insects which 

 infest decaying wood to be subject to the attacks of such parasites. 



A LIST OF THE BUTTERFLIES OF PHILADELPHIA, PA.* 



BY HENRY SKINNER, M.D., AND E. M. AARON. 



( Continued from page IJI.) 



Pyrameis Cardui. — Usually common ; some years quite rare. 



Junonia ccenia. — Quite local ; never very common. Mr. Scudder, on 

 page 501, speaks of its " rapid, strong and enduring flight." This would 

 seem to indicate that the habits of this insect in the New England States 

 differ materially from those in this locality or further south. It is rare 

 that this butterfly is here observed over a foot from the ground, and then 

 its flight is most erratic, and usually consists of a few fluttering strokes of 

 the wing followed by an idle sail. This is also the manner of flight from 

 Virginia to Florida, according to the observations of E. M. Aaron. 



Limenitis ursiila. — Rare. 



Limenitis disippus. — Common. 



Nconympha canthus. — Rare. A few specimens have been taken 

 near Gloucester, N. J. 



Neonympha eurytris. — Common in restricted localities. 



Satyrus pegala. — Exceedingly rare ; taken at Mount Holly, N. J., by 

 E. M. Aaron in 1884. It is recorded as from Gloucester, N. J., by the 

 collectors of twenty years ago.
