Butterflies. 
So little time was spent away from the immediate vicinity of 
lakes and streams (in fact most of my time was spent in the 
lakes and streams) that the number taken of such conspicuous 
insects as butterflies is not large. These were sent to Mr. J. L. 
Graf of Pittsburg. 
Anosia plexippus L.,Searchmont, Hayden; one specimen seen but 
not taken. 
Argynnis atlantis Edwards, Searchmont, Hayden.

Diptera. 
The Diptera, exclusive of Syrphidae, were sent to Professor 
Jas. S. Mine and the Syrphidae were sent to Professor R. C. 
Osburn. Their lists follow: 
The following eighteen species of Diptera are all well known, 
with the exception of what I have called Laphria terraenovae. 
Macquart described this species from specimens taken in New¬ 
foundland and it appears that it has not been recognized since. 
His description is very short and consequently it is with some 
doubt that the specimens before me are given the name, but the 
points mentioned agree so well that I know of no good reason 
why they might not be of the species in question. 
The collection contains the finest series of Chrysops excitans 
Walker that I have ever seen. This species is not rare, but its 
habitat is in such high latitudes that specimens are not often 
taken. Over twenty specimens were taken at Heyden, Ontario,. 
August 6th.
