Tue CRANE-FiLIES oF NEw York — Part II 919 
Breathing horns reddish brown; thoracic dorsum green, with a brownish tinge; 
bdomen uniformly pale green, posterior half of each dorsal segment a little darker. 
Cephalic crest small and compact, consisting of two prominent but closely approximated 
obes which are separated by a deep U-shaped notch, the tips acute and directed forward; 
n outer face before apex a short seta. Labrum broadly obtuse at tip. Labial lobes roughly 
riangular, divergent. Maxillary palpi short and stout, narrowed toward tip. Antennal 
Heaths with a slender tubercle at base above eye. 
Pronotal breathing horns broad at base, narrowed to the acute tip which is directed almost 
entrad; viewed from above, horns very broad basally and with a dorsal carina; ventral 
ide at base transversely wrinkled; a small setiferous lobe just in front of breathing horns, 
irected laterad. Mesonotum behind breathing horns with a high compressed carina, on 
ither side of this produced into a lobe directed cephalad and laterad; mesonotum moderately 
eclivitous (Plate LXIX, 369), at crest with numerous setiferous tubercles which are fewer 
n number and more widely separated along shoulder. Leg sheaths reaching to about middle 
f fourth abdominal segment; hind legs a little longer than fore legs; middle legs very short, 
nding opposite base of last segment of fore legs. 
Abdominal segments divided into two narrow basal rings and a broad posterior ring; 
n pleura a distinct spiracle, opposite posterior annulus and nearer dorsal margin; posterior 
nnulus, before caudal margin, with a dorsal and a ventral row of long, stout setae. Setae 
n abdomen as follows: on pleura, a seta opposite second basal ring, a second ventrad of 
piracle, and two setae caudad of spiracle, the posterior one a little more dorsal in position; 
on tergites, two stout setae lying transversely on the margin opposite spiracle, a third seta 
t end of terminal rows of bristles; on sternites, a group of two transverse setae on posterior 
ing, slightly below level of spiracle and rather widely separated by the broad midventral 
area. Female cauda (Plate LXIX, 370) with dorsal acidothecae short, distinctly upturned, 
and ending in a small, subacute tip; before apex with two very short setae; a short blunt 
tubercle near base of valves; ventral lobes short, their tips very blunt; dorsum of segment 8 
ith two blunt median tubercles, one immediately behind the other.

Erioptera vespertina O. 8. 
1859 Erioptera vespertina O.S. Proc. Acad. Nat. Sci. Phila., p. 226. 
Erioptera vespertina is a characteristic inhabitant of open swamps and 
et meadows. It has not been reared, but a pupa found in organic mud 
in the Basin Swamp, Orono, Maine, on June 24, 1913, undoubtedly belongs 
o this species. The associates are discussed under the account of Bittaco- 
orpha clavipes (page 785).

Breathing horns reddish brown; thoracic dorsum reddish brown, with an interrupted
