THE CRANE-FLIES OF NEW YORK PART II 937 



broad fusiform areas on anterior portion of abdominal segments except basal and apical; 

 hairs along margins of segmental incisions more distinct than elsewhere because of their 

 bein-; slightly curved upward; apical segment with five processes, their structure and mark- 

 ings as in figure [Plate LXXIV, 397]; anal ventral blood-gills in the form of four short 

 rounded protuberances. 



The pupa is described from four cast skins, kindly presented by 

 Mr. Hyslop: 



Pupa.- Length, 8-10 mm. 



Cephalic crest a low, blunt tubercle on either side of median line, each tipped with a long, 

 stout seta. Labrum broad, elongate, obtuse at tip, completely separating triangular labial 

 lobes. Sheaths of maxillary palpi moderately slender, tapering gradually to tip. Antennal 

 sheaths moderately elongated, extending to about opposite wing root; basal segments angulate. 

 Pronotal breathing horns (Plate LXXIV, 399 and 400) small, trumpet-shaped, very flattened, 

 median area lacking and hence the margins contiguous; just proximad of breathing horns 

 a large, roughly triangular lobe on either side, immediately behind which are two small 

 setae. Mesonotum moderately declivitous, at crest rather tumid, but unarmed, with a 

 few parallel grooves on either side of median line; lateral angle of thorax very sharp, before 

 tip with two setae, one very powerful, the more dorsal one abortive; a strong seta on either 

 side of mesonotum behind crest. Wing sheaths short, ending just before tip of second 

 abdominal segment. Leg sheaths (Plate LXXIV, 398) very short, ending just opposite tip 

 of second abdominal segment and thus projecting but slightly beyond wing tips; hind legs 

 a little the shortest, but no striking difference in length of various sheaths. 



Abdominal segments subdivided into a narrow basal ring and a much broader posterior 

 ring; abdominal segments on dorsum with four transverse rows of tiny but stout setae, two 

 on basal ring and two on posterior ring, one being subbasal, the other subterminal, in position; 

 starnum with only the subterminal row of setae present, but this well marked, the other 

 rows merely vestigial; on either side of dorsum, just cephalad of ends of subterminal row 

 of setae, a powerful bristle; in alinement with these and subequally spaced, two smaller 

 setae; a strong pleural seta on a raised papilla opposite basal ring and three opposite posterior 

 ring, the two anterior being larger, the posterior one very small; .sternum with a strong seta 

 on extreme lateral margin of posterior ring; lateral spiracles distinct, on segments 2 to 7. 

 Male cauda (Plate LXXIV, 401) with ventral lobes small, blunt, rather widely separated 

 basally but converging apically; dorsal lobes powerful, divergent, and rather acute at tips; 

 at base of each near lateral margin a short bifid knob sending one arm dorsad, the other 

 laterad; at base on cephalic angle a short, stout seta; two long, powerful, lateral setae on 

 either side, and a single powerful seta on either side of dorsum, immediately behind which 

 is a blunt tubercle. Female cauda with sternal valves elongate, powerful, at their tips ter- 

 minating in slender, divergent points; dorsal valves small, blunt, divergent, located at base 

 of sternal valves, at their tips with a short, slender spine directed backward; base of seg- 

 ment about as in male.
