The Crane-Flies of New York — Part II 881 



Pupa (Plate LI, 247) very similar to that of Eriocera longicornis, differing only in its small 

 size, greater development of seapal spine, lack of projection on mesonotal prcscutum, and 

 a few lesser characters. Cephalic crest (Plate LI, 248 and 249) as viewed from beneath, 

 very different in shape. Fore pair of legs much shorter than the others, ending just beyond 

 posterior margin of second abdominal segment; hind pair of legs extending far beyond the 

 others, ending beyond midlength of third abdominal segment; in some .specimens the tarsal 

 segments much closer to posterior margin of third abdominal .segment, but usually a marked 

 difference in tips of tarsi of the various legs. Cephalic crest as viewed from side, triangular, 

 ending in an acute point directed strongly forward. Viewed from beneath, lobes con.spicu- 

 ously triangular, pointed, lying parallel or slightly divergent and separated by a deep 

 median split. Spine on scape of antennae very large, conspicuous. Tubercle on labrum 

 strongly developed. Antennal sheaths of male very long, those of female much shorter. 

 Pronotal breathing horns short, straight. Mesonotum strongly wrinkled along median 

 line; scutellar lobe not developed. Wing pads dark, venation not showing clearly but, if 

 made out, the very short cell R' and the reduced M characteristic of Hexatoma alone. 

 Posterior leg sheaths extending beyond level of middle legs, these, in turn, being longer 

 than sheaths of fore legs. 



Abdomen (Plate LI I, 2.52) with about thirty-four spicules on sternite 4, about thirty 

 in a straight, uninterrupted row on tergites 3 and 4, and about twenty on tergite 5. 

 Chaetotaxy about as in Eriocera longicornis, but the seta lying ventrad of spiracle on pleuritea 

 much farther ventrad and very weak. Male cauda with sternal lobes strongly rounded, 

 enlarged, and bent suddenly dorsad. Female cauda as that of male; ovipositor viewed 

 from side with an obtuse notch; from beneath, sternite obtusely pointed and with a deep 

 median .split; from above, tergite almost flat across caudal margin, the lateral angles rounded, 

 with a deep median split.

Larva. — Spiracular disk surrounded by four lobes which are rarely (as in Eriocera cinerea, 

 subobsolete, inner face lined with brown or black, tips with fringes of moderately long hairs. 

 Head capsule long, narrow, the constituent plates very slender; dorsal plate completely 

 divided tho contiguous or approximated behind. Labral sclerite large and conspicuous, 

 sensory tubercles and papillae crowded on median cephalic region. Mandible long, acute
