The Crane-Flies of New York — Part II 889 



Antenna elongate, a little narrower at base, at tip with three or four hyaline, seta-like papillae 

 which are of various diameters and shorter than the segment, the largest of these papillae 

 delicately sculptured with transverse lines. Mandible acute, curved, at about midlength 

 with a blunt, flattened tooth, this with a smaller similar tooth in its axil. Maxillary blade 

 very long and slender, about half length of capsule. 



Pupa. — Length: male, 13.2-15.2 mm.; female, 14-15.4 mm. 



Width, d.-s.: male, 2.1-2.2 mm.; female, 1.8-1.9 mm. 

 Depth, d.-v. : male, 2.1-2.3 mm.; female, 2.2 mm. 



Young pupae very pale; soft abdomen almost white; chitinized anterior part of body very 

 pale brown. Older pupae much darker, the chitinized part becoming black with a bronzy 

 reflection; abdomen very dark brownish gray; breathing horns dark brown on apical half. 



Cephalic crest (Plate LV, 275) very prominent, elongate, tapering to the subacute tips; 

 lobes with blunt tubercles behind, as well as four long setae on each lobe, three on dorsal 

 margin and a longer one on lateral face at about midlength; viewed from in front, lobes 

 separated by a broad, square or U-shaped notch; ventral part of crest produced forward 

 between antennal bases as a depressed lobe bearing a stout seta on either side. Tubercle 

 on antennal scape very prominent. A slightly smaller tubercle on either side of clypeus, 

 with a small rounded knob cephalad of each. Labrum truncated. Labial lobes roughly 

 diamond-shaped. Maxillary palpi very broad, rectangular, tips truncated. Antennal 

 sheaths of male greatly elongated, enlarged at base; viewed from beneath, the swollen bases 

 nearly contiguous on median line, just above and proximad of inner margin of eye, with 

 scapal tubercle described above. Antenna of male exceeding wing pads, those of female 

 ending just beyond wing base. Pronotal breathing horns short and stout, straight, trans- 

 versely wrinkled, directed cephalad, dorsad, and laterad; when viewed from beneath, com- 

 pletely concealed by large cephalic crest. Thoracic notum convex; me.sonotum transversely 

 wrinkled (Plate LV, 277); median lobe of mesonotal scutellum projecting dorsad and cau- 

 dad as a blunt point (Plate LV, 272). Two or three setae above wing axil. Lateral angles 

 of thorax subacute, with a weak seta. Wing sheaths attaining end of second abdominal 

 segment. Leg sheaths ending before caudal margin of third abdominal segment; tarsi of 

 hind legs the longest, the two inner pairs ending about on a level (Plate LV, 273). 



Abdominal segments (Plate LVL 285) divided into a basal and a posterior ring; tergitea 

 on posterior ring with a subterminal transverse row of spines, these varying from about thirty- 

 two on segment 3 to about fourteen on segment 7; these rows of spines interrupted on dorso- 

 median line; at each end of row, three long setae, and two additional groups of setae inter- 

 spersed along row; two setae on either side at anterior -lateral angle of ring; tergites on basal 

 ring unarmed; sternites on posterior ring with a subterminal transverse row of from twenty- 

 four to thirty-two spines, with two setae at each end of row; an isolated seta on caudo- 

 lateral margin, close to pleura; a group of two approximated setae near base of posterior 

 ring, on either side, about at level of spiracles. Sternites on basal ring unarmed; pleuritos 

 on basal ring with a solitary seta at about midlength, but slightly nearer dorsal margin; 

 posterior ring with two setae dorso-caudad of spiracle, and a third seta ventrad of it. A'al • 

 Cauda (Plate LVL 286) very blunt, much narrower than remainder of abdomen; ventral 

 lobes very blunt; dorsal lobes short, stout, ending in sharp points directed dorsad, on out'^r 

 face a long and a short seta; segment 8 with a dorsal trapezoid of four lobes, the posterior
