THE CRANE-FLIES OF NEW YORK PART II 917 



arched transverse chitinized bar. Hypopharynx about as in Molophilus. Antennae rather 

 closely approximated, directed cephalad; basal segment moderately elongated, cylindrical; 

 apical papilla relatively small, elongate-oval. Mandible very small, with blunt teeth; 

 apical point short, blunt; ventral row of teeth about three in number, often very blunt. 

 Maxilla as in Molophilus, but outer lobe with the vestiture of hairs rather longer. 



Pupa. Length, 7.2-8.2 mm. 



Width, d.-s., 0.8-0.9 mm. 

 Depth, d.-v., 1-1.1 mm. 



Head light brown; thorax anterior to declivity conspicuously darker brown; remainder 

 of body light yellowish brown; breathing horns light yellow. (In fully colored individuals 

 the head and the thorax with their appendages become much darker, almost black, but the 

 breathing horns retain their conspicuous yellow color.) 



Head short, face tumid. Eyes of male very large, widely separated by front; eyes of 

 female smaller. Cephalic crest consisting of two prominent lobes; viewed from side, these 

 lobes sharply pointed and directed slightly forward, with a seta on outer ventral face before 

 tips; viewed from front, lobes rounded, ending in acute tips, separated by a deep, rather 

 narrow, V-shaped notch. Front between eyes narrowed toward labrum, which is rather 

 sharply pointed. Labial sheaths small, the lobes contiguous with their apices truncated, 

 the lateral angles obtuse or produced into a tiny lobe. Sheaths of maxillary palpi short 

 and stout, tapering gradually to tips. Antennal sheaths moderately elongated, angulated 

 at segments, ending just beyond base of wing. Pronotal breathing horns stout, expanded 

 at base, almost straight and only slightly divergent, somewhat compressed, transversely 

 wrinkled basally; a small setiferous tubercle in front of base of breathing hern. Mesonotum 

 precipitous, at crest (Plate LXVII, 359) on either side of median line with abundant tiny 

 setiferous tubercles bearing long, pale hairs, these tubercles continued back along shoulder. 

 Lateral margin of thorax with two small setae. Wing sheaths ending before tip of second 

 abdominal segment. Leg sheaths (Plate LXVII, 360) short, attaining base of fourth 

 abdominal segment; tarsi of hind legs the longest, those of middle pair the shortest; fore legs 

 with femora and tibiae very short. 



Abdominal segments (Plate LXVII, 361) divided into two annuli by a constriction near 

 midlength, the anterior ring very indistinctly subdivided further into two lesser annulets; on 

 segments 4 to 7, before caudal margin of posterior ring en both dorsum and sternum, a trans- 

 verse row of small, conspicuous, blackened, setiferous tubercles, which are more distant 

 from one another near ends of rows; on basal abdominal segments these tubercles less evident 

 but still present. Pleura with small but probably noa-functional spiracles, which are very 

 indistinct in young pupae but are more evident in fully colored individuals; these spiracles 

 located near base of posterior ring. Setae on abdomen as follows: on sternal segments, 

 one seta just caudad of end of row of spicules, a second at lateral end of this row, inter- 

 mixed with spicules, two on posterior ring on a level with spicules; on tergal segments, a 

 strong seta on a line with spiracles, another seta below end of row of spicules; on pleura, one 

 seta just ventrad of spiracles, and two post-spiracular and one ante-spiracular setae. Male 

 cauda (Plate LXVII, 362 and 363) with ventral lobes obliquely truncated, blunt at tips, 

 projecting beyond level of subacute dorsal lobes; dorsal lobes slender, slightly divergent 

 apically, blackened before tips and with two setae at tips on outer face; at base of cauda,
