thé form and structure of the larva of a species that lives in the 
water of spring brooks [also copied from the above mentioned 
bulletin]. ; 
Crane flies are much neglected by collectors of insects, for 
at best they do not make a very attractive collection, and 
good specimens are obtained only with more than the usual 
care that is bestowed upon them. At their worst they are an 
unsightly assortment of mostly legless fragments. Their legs 
break off very easily, and rough handling will surely lose 
them. But if specimens are taken in a net with reasonable 
care, killed in a cyanide bottle without handling, and pinned soon 
after killing, there will be little difficulty in getting specimens with 
six legs. It will not do to leave them lying around in the 
cyanide bottle; for the legs soon become detachable with the 
slightest touch. If specimens are to be spread, the spreading 
should be done on a flat board drilled with small holes, and 
the flies spread in inverted position with the pin heads stuck down 
the holes.t Thus placed, both wings and legs are easily arranged 
in any position desired. 
My own collecting of crane flies has been done chiefly about 
water and with the aid of a trap lantern. I have obtained thus 
mainly the smaller and less conspicuous species, nearly all of 
which belong to the subfamily Limnobiinae. [ have found 
few new species, and of these I have described only those I 
wished to refer to by name in the venation study which follows. 
I have been on the lookout especially for such as would show 
new venational peculiarities or variations. 
The fewness of the new forms encountered is evidence of 
the thoroughness of the collecting done by Baron Osten Sacken 
on his visits to West Point, Saratoga and Trenton Falls, while 
he was in the diplomatic service at Washington. Trenton 
Falls especially yielded him a large number of new species. 
Old Forge lies near Trenton Falls, and furnishes kindred habi- 
tats, and I was much pleased while collecting there to be 
able to pick up most of Osten Sacken’s species.. 
In the following list are included the names of 104 species 
of crane flies nearly all of which have now been recorded from 
the State. The list is of course very incomplete, and it is hoped
