at apex. Labial lobes oval. Maxillary palpi slender. Antenna of female moderately 
elongated, reaching to just beyond wing root. Pronotal breathing horns (Plate XLIX, 233) 
elongate, cylindrical, sinuous, transversely wrinkled, apex scarcely enlarged but deeply 
split on inner margin; a setiferous tubercle ventrad and laterad of breathing horns. Thorax 
with a very high anterior median crest. A slender, setiferous tubercle above wing axil, 
and two others on either side of median line. Sheaths of haltercs long and slender. Leg 
sheaths ending about on a level, or those of hind legs the shortest and those of fore legs a 
little longer. : 
Abdominal segments divided into two annuli. Tergites (Plate XLIX, 235) on posterior 
ring with a caudal row of blunt, naked tubercles; at end of row two setae; on either side of 
median area and just in front of row, a large setiferous tubercle; at base of ring two naked 
tubercles, one on either side of median line; two slender setiferous tubercles near margin 
of ring. Basal ring with four naked tubercles. (The third pair of tubercles found in the 
pupa of Pilaria quadrata is vestigial.) Pleura with four tubercles, two on each ring, the 
basal one of each ring setiferous, the posterior one naked. Sternites with six naked tubercles 
on basal ring, arranged in three transverse pairs; on posterior ring at base two setiferous 
tubercles, each with two bristles, directly behind last naked tubercle of basal ring; at caudal 
margin two or three large tubercles near end of row and about four or five small naked tubercles 
between. Female cauda (Plate XLIX, 234 and 236) very elongate, tergal valves slightly 
upcurved, terminating in a sharp spine and with two setae on outer face. Eighth tergite 
with four elongate lobes; posterior pair blunt, directed laterad; anterior pair elongate, slender, 
with two setae laterad of each. <A blunt lobe on pleural region. Pleura with three or four 
powerful tubercles, with a seta located between the more dorsal pair. Sternal region with 
four small setae, two on either side of broad median area. 
Nepionotype.— Orono, Maine, July 1, 1913. No. 50-1913. 
Neanotype.— With type larva. 
Pilaria recondita (O. 8.) 
1869 Limnophila recondita O. S. Mon. Dipt. N. Amer., part 4, p. 212-213. 
Pilaria recondita is a common crane-fly thruout the northeastern 
United States. The immature stages are swamp inhabitants, and are 
very frequently found in exactly the same situations as are those of P. 
tenuipes. P.recondita belongs to the same group as P. tenuzpes, and the 
pupae of the.two species are very difficult to distinguish. 
Larva.— Length, 15 mm. 
Diameter, 1.2 mm. 
Color a uniform light yellow. i. 
Body covered with a long, appressed, yellow pubescence and with a few long setae. 
Spiracular disk very small, in a position of rest almost closed, surrounded by four lobes; 
ventral lobes moderately elongated, fringed with long, golden-yellow hairs which are longest 
at tips of lobes; if bent backward these elongate hairs extending to beyond gills; inner face 
of lobes almost unmarked, with only a delicate brown line extending from tip toward base
