THE CRANE-FurEs oF New York — Part II 967 
The adult flies of Cylindrotoma tarsalis Johns., the only species that 
the writer has ever found in nature, are common on rank vegetation in 
cool, boggy, and swampy woods. The immature stages of the genotype, 
C. distinctissima (Meig.), have long been known, having been discussed 
by Schellenberg (1803), Boie (1838), Zeller (1842), Kaltenbach (1874), 
and others. The larva shows some resemblance to that of Phalacrocera, 
but is almost entirely terrestrial in its habits, feeding on the leaves of 
various spermatophytic plants such as Caltha palustris, Anemone nemorosa, 
Ranunculus repens, Chrysosplenium, Stellaria nemorum, Sanicula europaea, 
Viola biflora, Valeriana officinalis, Allium, and others. It attains a length 
of nearly 25 millimeters, and is narrow, depressed, tapering to either end, 
and of a grass-green color. There is a slight dorsal ridge from which a 
row of short, fleshy spines projects, these spines being directed backward 
and one spine on each segment being longer than the others. There is a 
broad lateral margin bearing very short processes, and there are also 
eight pairs of ventral ridges without hooks and a pair of longer backward- 
directed processes near the anus. The pupa affixes itself to stalks or leaves 
by the caudal end, to which the remains of the last larval skin adhere. 
The larvae generally remain on the lower surface of the leaves, on which 
they feed, gnawing holes in them. When about to pupate they generally 
leave their food plants and fasten themselves on grass blades and leaves 
near by, usually pupating the following day. From the foregoing obser- 
vations 1t would seem that there are in the various localities two genera- 
tions a year, one in the spring and the other in the autumn. 
The life history of C. splendens has recently been worked out in con- 
iderable detail by Dr. A. E. Cameron, thru whose kindness the writer 
as received specimens for study.

Cylindrotoma splendens is an interesting crane-fly occurring from British 
olumbia northward to Alaska. Dr. Cameron’s excellent notes on the 
ife history of this species are abstracted in detail on pages 708 to 710 
f this paper. The following descriptions were made from material sent
