The Crane-Flies of New York — Part II 997 



end and continued across disk, meeting its fellow of the opposite side between spiracles; 

 dorsal margin of lateral lobes touching spiracles; each of the lobes marked with a capillary 

 dark brown hne down center of inner face, this beginning near ends of lobes and extending 

 almost to base; lobes fringed with long hairs, these very tiny near base, longer near tips of 

 lobes, but scarcely, if at all, interrupted between lobes. Spiracles large, circular, sepa- 

 rated by a distance a little greater than diameter of one. Anal gills six, long, slender, 

 unbranched. 



Head capsule of the usual tipuline type. Labrum covered with dense, short hairs, those 

 on lateral lobes longer. Mentum (Plate XCI, 498) u.sualiy seven-toothed, in some casess nine- 

 toothed; median tooth slender, lateral teeth flattened, subacute. Hypopharynx (Plate 

 XCI, 499) narrow, five-toothed. Antenna (Plate XCI, 500) long and slender; first segment 

 a little enlarged near base; at apex several tiny sensory papillae; auditory plate near base 

 of segment. Mandible (Plate XCI, 501) moderately large, with two large dorsal and about 

 three 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 

 old specimens the general coloration is very dark brown; in younger specimens the abdomen 

 is more or less distinctly lined with brown.) 



Thorax subterete; abdomen depressed, lateral margins flattened. Labrum broad, apical 

 point narrow. Labial lobes broad, slightly separated on median line. Maxillary palpi 

 short, stout, apex recurved. Antenna moderately elongated, extreme tip darkened. Pro- 

 notal breathing horns long and slender, unequal in length, the longer about 9 or 10 mm. 

 in length, the other 6 mm., at tips split into divergent flaps (Plate XCI, 504) almost as in 

 the hexatomine genera Pseudolimnophila and Pilaria, which live in the same muddy sit- 

 uations. Mesonotum (Plate XCI, 503) transversely wrinkled. Leg sheaths reaching posterior 

 margin of third abdominal segment; hind legs the longest; middle legs a little shorter than 

 fore legs. 



Abdominal segments divided into a basal and a posterior ring; tergites with basal ring 

 unarmed; 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- 

 gites 3 to 7, three to fifteen spines; two small spines with setae near anterior lateral angle 

 of posterior ring; pleurites with a small setiferous spine on basal ring, and two such spines 

 on posterior ring located side by side; sternites with the basal ring unarmed, posterior ring 

 armed similarly to that of tergites; in addition to posterior row of spines, a pale oval area 

 on either side of midventral line, each with two transversely placed spines. Male cauda 

 (Plate XCl, 505) with four powerful lobes on dorsum of last segment, directed dorsad and 

 slightly caudad, lobes bearing three or four small spines before tips; between anterior pair 

 of lobes, two additional slender lobes, each ending in two acute spines.
