THE CRANE-FLIES OF NEW YORK PART II 1003 



Coloration pale dusky, darker above; dorsum behind with two broken lines which are 

 divergent on each annulus, those of anterior annulus made up of three circular spots; pleura 

 with a conspicuous dark brown stripe; venter almost uniformly pale, with indistinct lines; 

 anterior part of thoracic segments darker. (In life the color is rich reddish brown, and the 

 pleural stripe is not evident.) 



Form terete. Body covered with a delicate, pale pubescence, in addition to the usual 

 setae. Chaetotaxy as follows: tergites (Plate XCIV, 521) with a transverse row of six setae 

 on posterior ring before margin, the two innermost solitary, each lateral pair closely 

 approximated; a solitary seta on extreme lateral margins of tergite, at margin of dark pleural 

 stripe, and at about midlength of posterior ring; pleura on basal ring with a single seta, pos- 

 terior ring with a group of about three or four setae, one larger than the others; sternites 

 with four widely separated setae on posterior ring, the lateral pair a little nearer posterior 

 margin than the median pair. Spiracular disk (Plate XCIV, 522) surrounded by six lobes 

 which are moderately slender; ventral pair a little longer, dorsal pair a little shorter; all the 

 lobes broadly margined with pale brown; ventral lobes having in addition a black capillary 

 line extending from tips backward to beyond midlength of lobes, this line broadest at tip, 

 gradually narrowing, and becoming paler toward base of lobes; below each spiracle, two 

 conspicuous black dots; lobes fringed with numerous rather long hairs. Spiracles large, 

 separated by a distance a little greater than diameter of one. Anal gills six, one pair much 

 shorter than the others, consisting of a basal branch of the anterior gill. 



Head capsule rather small, of the usual tipuline type. Mentum (Plate XCIV, 519) very 

 broad, anterior margin almost transverse, seven-toothed, median point the longest. Hypo- 

 pharynx (Plate XCIV, 520) with five teeth, which are very short and blunt giving anterior 

 margin a deeply crenulated appearance; before hypopharynx a rounded lobe which is densely 

 covered with six short, blunt, chitinized points, this being probably the prementum. Antenna 

 elongate-cylindrical; apex with apical disk very small, button-like. Mandible small, with 

 about one dorsal and two ventral teeth. Maxilla slender, densely hairy; palpus subglobular, 

 with several small, hyaline papillae. 



Pupa. Length, 17-19 mm. 



Width, d.-s., 2.8-3.2 mm. 

 Depth, d.-v., 3-3.3 mm. 



Coloration brown; wing sheaths, except in older individuals, pale; pleural region of abdomen 

 light yellow; abdominal incisures often pale. 



Head rather small. Cephalic crest low and indistinct, with tiny setae. Labrum broad, 

 apex pointed. Labial lobes oval, contiguous at inner end. Maxillary palpi strongly recurved 

 at tips. Antenna slender, moderately elongated, extending some distance beyond wing 

 root. Pronotal breathing horns equal in length, rather short, the moderately long tips flat- 

 tened, smooth; two small, approximated setae on either side of median line. Wing sheath 

 (Plate XCIV, 523) extending just beyond end of second abdominal segment; venation dis- 

 tinct. Leg sheaths extending beyond base of fourth abdominal segment; fore tarsi con- 

 siderably shorter than the others. 



Abdominal segments with armature of posterior ring weak, the spines very short and stout, 

 with a few setae; maximum number of spines on the tergites about twenty; lateral anterior 

 angle of posterior ring of tergites with two small spines: pleurites with one basal spine, and
