REPORT OF THE STATE ENTOMOLOGIST I907 203 
that the key and the figures will facilitate the collection and identi- 
fication of much new material in this neglected group. 
I have found the material accumulated in the course of the 
station work of the past two seasons sufficient in amount and 
variety, and in the range of forms brought together to serve 
for the basis of a study I have long wished to make of the 
venation of the crane flies. These are generally recognized 
as being among the most primitive of the Diptera, and among 
the more generalized of the families that seemed likely, on 
account of the great number. of their members and _ conse- 
quent variety of interrelated forms, to offer materials for the 
solution of some pressing problems in taxonomy. ‘That among 
the Tipulidae might be found the key to the solution of some 
of the remaining problems of venation has seemed altogether 
probable. 
Preliminary list of New York crane flies 
The following list is based on the collections accumulated 
during the course of the summers of 1905 and 1907 (mainly by 
trap lantern), the published records (chiefly taken from 
Aldrich’s Catalogue of North America Diptera) and data avail- 
able in the Cornell University collection. For the conven- 
tence of the user, I follow the order of arrangement of the 
above mentioned catalogue, although, as stated elsewhere I 
believe the natural order of arrangement of the group is therein 
frequently inverted. 
i Geranomyia Camademsis Wes, A iii speck 
mens were taken in trap lanterns at Old Forge during August. 
Specimens from Manlius, N. Y. August 20, and from Ithaca 
(July 14-16) are in the Cornell University collection. This 
species hovers about wet timbers on the edge of streams or 
on wave beaten shores. ;

I encountered at Old Forge in two very different situations. 
A little company of males I observed hovering about the 
trunk of a tall beech tree in the yard of the cottage in which 
I lived (Camp Sakheywey). The trunk was partially moss 
covered, and stood on the edge of the forest, and just before
