THE CRANE-FLIES OF NEW YORK PART II 885 



the lateral pair directed outward, the inner pair directed caudad. Head capsule (Plate 

 LIV, 267) broad in proportion to its length, measuring 3.5-3.8 mm. by 1.8-2 mm. (across 

 dorsal plates). Papillae at tip of antenna short, not more than one third length of seg- 

 ment. Mandible (Plate LIV, 271) lacking a prominent conical tooth at midlength, such as 

 is found in E. cinerea and other species. 1 < 



Pupa. Length: male, 26.5-27 mm.; female, 25-28.5 mm. 



Width, d.-s.: male, 3.4-3.9 mm.; female, 3.4-4 mm. 

 Depth, d.-v.: male, 4-4.2 mm.; female, 3.5-4 mm. 



In life, pupae varying in color from very pale yellowish to dark brown or almost black, 

 the deepest color being that of head and thorax of old pupae; body often showing bronzy 

 reflections. 



Cephalic crest very reduced, scarcely projecting beyond level of antennae; viewed from 

 beneath, somewhat quadrate, the anterior lateral angles produced into small pointed lobes 

 bearing; a small seta at apex; viewed from side a second pair of lobes is seen, these being 

 subequal to anterior lobes in size, and likewise setiferous. Spine of antennal scape very 

 large, somewhat curved, directed ventrad. Inner caudal surface of eye with a conspicuous 

 tubercle. Tentorial region produced into a small median tubercle. Tubercles at base of 

 labrum very large, close together, their tips strongly chitinized; a small seta above each 

 of these labral tubercles and another small seta on each cheek. Pronotal breathing horns 

 long, slender, broad at base, flattened and rather pointed at tips, the organ arcuated so that 

 apex is bent strongly ventrad. Mesonotal scutellar lobe (Plate LV, 280) prominent, rather 

 strongly projecting. Wing pad light brown, venation showing very clearly, the presence of 

 cell MI in connection with elongate antennae in male sex being found in this species alone 

 in eastern North America. Leg sheaths with tarsal sheaths ending on a level, about opposite 

 end of third abdominal segment. 



Second abdominal tergite with a conspicuous basal tubercle on either side of median line. 

 Abdominal segments (Plate LVI, 283) with subterminal rows, of spines, there being about 

 twenty to twenty-two on tergites 2 to 5; tergites 6 and 7 destitute of spines but with four 

 subapical setiferous tubercles; tergites 2 to 7 with a conspicuous setiferous tubercle on ventro- 

 cephalic angle of each posterior ring; eighth tergite concave on posterior margin, bearing a 

 pair of strong apical tubercles on either side of median line. Pleural region of abdomen 

 rather restricted, longitudinally wrinkled. Spiracles large, elliptical, transverse, placed about 

 opposite midlength of segments. Three small setiferous tubercles ventrad and caudad of 

 spiracle, and another similar tubercle on dorsa-cephalic angle of each pleuron. Semites 

 on segment 3 with two spines on each outer angle; segments 4 to 6 with from sixteen to twenty 

 spines; segment 7 with about ten spines; an isolated set'ferous tubercle caudad and dorsad 

 of ends of row; segments 4 to 7 with a setiferous tubercle about midlength of posterior ring; 

 segment 8 lacking soft pleural region, bearing an apical row of strong spines which are inter- 

 rupted only on dorsum and for a small space on median line of venter, there being about 

 twenty of these spines in the circlet. Male cauda (Plate LV, 281 and 282) with ninth sternite 

 rounded, swollen, with a deep median furrow bearing a small lobe on ventral side at end of 

 split; ninth tergite produced caudad into two strong conical points separated by a V-shaped 

 notch, these points directed caudad and slightly dorsad, each one a little split near tip on 

 outer face and with a prominent lateral tooth at about midlength. Female cauda (Plate
