THE CRANE-FLIES oF NEw York — Part II 997 
nd and continued across disk, meeting its fellow of the opposite side between spiracles; 
orsal margin of lateral lobes touching spiracles; each of the lobes marked with a capillary 
ark brown line down center of inner face, this beginning near ends of lobes and extending 
Imost to base; lobes fringed with long hairs, these very tiny near base, longer near tips of 
obes, but scarcely, if at all, interrupted between lobes. Spiracles large, circular, sepa- 
ated by a distance a little greater than diameter of one. Anal gills six, long, slender, 
nbranched. 
Head capsule of the usual tipuline type. Labrum covered with dense, short hairs, those 
m lateral lobes longer. Mentum (Plate XCI, 498) usually seven-toothed, in some cases nine- 
oothed; median tooth slender, lateral teeth flattened, subacute. Hypopharynx (Plate 
CI, 499) narrow, five-toothed. Antenna (Plate XCI, 500) long and slender; first segment 
little enlarged near base; at apex several tiny sensory papillae; auditory plate near base 
f segment. Mandible (Plate XCI, 501) moderately large, with two large dorsal and about 
hree ventral teeth; prostheca large. - Maxilla small; palpus large, cylindrical, apex truncated. 
Pupa.— Length, 15-22 mm. 
Width, d.-s., 2.4 mm. 
Depth, d.-v., 2.6 mm. 
Coloration dark brown; lateral and posterior margins of abdominal segments paler. (In 
Id specimens the general coloration is very dark brown; in younger specimens the abdomen 
3 more or less distinctly lined with brown.) 
Thorax subterete; abdomen depressed, lateral margins flattened. Labrum broad, apical 
oint narrow. Labial lobes broad, slightly separated on median line. Maxillary palpi 
hort, stout, apex recurved. Antenna moderately elongated, extreme tip darkened. Pro- 
otal breathing horns long and slender, unequal in length, the longer about 9 or 10 mm. 
nm length, the other 6 mm., at tips split into divergent flaps (Plate XCI, 504) almost as in 
he hexatomine genera Pseudolimnophila and Pilaria, which live in the same muddy sit- 
ations. Mesonotum (Plate XCI, 503) transversely wrinkled. Leg sheaths reaching posterior 
argin of third abdominal segment; hind legs the longest; middle legs a little shorter than 
ore legs. 
Abdominal segments divided into a basal and a posterior ring; tergites with basal ring 
narmed; posterior ring with a subterminal transverse row of short spines, with a few setae 
located on lateral face of some of the spines; on second tergite, four to six spines, on ter- 
ites 3 to 7, three to fifteen spines; two small spines with setae near anterior lateral angle 
f posterior ring; pleurites with a small setiferous spine on basal ring, and two such spines 
n posterior ring located side by side; sternites with the basal ring unarmed, posterior ring 
rmed similarly to that of tergites; in addition to posterior row of spines, a pale oval area 
n either side of midventral line, each with two transversely placed spines. Male cauda 
Plate XCI, 505) with four powerful lobes on dorsum of last segment, directed dorsad and 
lightly caudad, lobes bearing three or four small spines before tips; between anterior pair 
f lobes, two additional slender lobes, each ending in two acute spines.
