THE CRANE-FLIES OF NEW YORK PART II 897 



Head capsule very compact, lateral plates united with broad dorsal plate except for a short 

 distance behind. Labrum (Plate LIX, 300) broadly transverse; cephalic margin truncate or 

 very slightly concave; epipharyngeal region with about five transverse interrupted rows of 

 setae. Mentum (Plate LIX, 302) of two entirely separated plates, each half with four teeth, 

 those at the ends the smallest, the outermost tooth tending to be reduced, the two middle 

 teeth of each side notably larger than the others; outside of mentum a thin plate, its inner 

 proximal margins nearly contiguous at median line of body. Hypopharynx labriform, pro- 

 jecting beyond level of both labrum and mentum; outer lateral angles densely hairy, 

 median posterior area with about eight small, hyaline spines. Antenna (Plate LIX, 301), in 

 caustic-potash mounts, hyaline; basal segment elongate-cylindrical, bearing at its tip about 

 two papillae as follows: a long, slightly curved, cylindrical papilla which is finely sculptured, 

 and immediately proximad of this a slightly smaller second segment of the antenna, bearing 

 near its tip three tiny papillae, an inner flattened subspatulate blade, and two longer cylin- 

 drical papillae; near base of this second antennal segment a long seta. Mandible (Plate LIX, 

 303) rather long and slender, apical point narrow; about four small lateral teeth near ventral 

 cutting edge, the most basad of these acute; a large dorsal tooth on cutting edge and two 

 very small acute teeth near base; on dorsal face of mandible two long setae, and two 

 somewhat shorter setae near heel of mandible; about five or six stout setae at prosthecal 

 region. Maxilla (Plate LIX, 304) consisting of two elongated lobes which are separate from 

 each other, the outermost the longer, the pale rounded palpus terminal in position; inner 

 lobe shorter, with three elongate setae, of which one is apical and the longest is sub-basal in 

 position. 



Pupa. Length, 4.5-4.7 mm. 

 Depth, d.-v., 0.8 mm. 



Color light yellowish brown, the thoracic dorsum paler; pronotal breathing horns dark 

 brown, apical quarter abruptly light yellow; abdomen brown, lateral and posterior parts 

 of each segment darker. 



Cephalic crest small, each lobe with three small setiferous punctures on anterior face; 

 ventrad of crest between antennal bases a prominent median lobe. Labrum broad; apex 

 truncated, indistinctly bifid. Labial lobes large, with a deep U-shaped median notch behind. 

 Maxillary palpi rather short and stout, ending before joint of fore legs (Plate LX, 307). 

 Pronotal breathing horns moderately elongate, curved slightly laterad, strongly divergent, 

 cylindrical, of uniform diameter thruout their length. Mesonotum not very gibbous (Plate 

 LX, 306). Thorax with a high anterior median carina. Wing sheaths extending beyond 

 base of third abdominal segment, the venation indistinct. Leg sheaths rather long, ending 

 at about one-third length of fifth abdominal segment; hind legs much longer than the 

 others, middle legs a very little longer than fore legs. 



Abdominal segments indistinctly subdivided into two rings, a narrow anterior ring and a 

 much broader posterior ring; abdominal armature very weak, lacking on segment 7; basal 

 annulus on tergites and sternites with a number of small pits on sides, these sometimes sparse 

 or lacking; posterior ring with a transverse row of numerous long, stout setae or delicate 

 spines before margin. Spiracles weak, at base of posterior ring. Male cauda (Plate LX, 

 309 and 310) with sternal lobes elongate, contiguous except at extreme tips; tergal lobes 

 terminating in very slender and acute curved points, directed caudad and dorsad; tergite
