Tur CRANE-FiLIES oF New York — Parr II 779 
ment 7, on which there are about fifteen. Abdominal pleurites with tubercles arranged in 
longitudinal rows, there being about six rows on each of segments 2 to 6, the rows being 
almost continuous for the whole length of abdomen; tubercles at caudal margin of each 
segment enlarged and powerful; on segment 6 the rows converging behind into a single 
powerful tubercle on caudal margin of segment; a similar enlarged tubercle on caudal margin 
of seventh segment; segment 7 and cauda narrowed. Male cauda (Plate XV, 22) with a 
prominent dorso-median lobe projecting directly away from the body; dorsal sheaths short, 
indistinctly bilobed; ventral sheaths very elongate, divergent (Plate XV, 23). Female cauda 
(Plate XV, 24) with the same prominent dorso-median lobe; acidotheca of ovipositor long, 
straight, beyond its midlength a blunt, conical tubercle directed laterad and slightly caudad; 
sternum (Plate XIV, 15) with ventral lobe only about half length of tergal acidothecae, caudal 
margin with three lobules. 
Nepionotype.— Orono, Maine, June 24, 1913. 
Neanotype.— With the larval type. 
Paratypes.— Both larvae and pupae, June 24 to July 5, 1913. 
SUBFAMILY Bittacomorphinae 
The following keys separate the genera of the subfamily Bittacomor- 
phinae: 
Larvae 
Size small (total length under 20 mm.); coloration black, breathing tuke light yellow; 
breathing tube entirely retractile; body covered with very long projections which are 
incased in a black, horny substance; mandibles with an inner comb of teeth. 
Bittacomorphella Alex. (p. 779) 
Size larger (total length over 40 mm.); coloration rusty red; body tapering gradually to the 
long, slender, partly retractile, breathing tube; kody covered with transverse rows of shorter, 
stellate tubercles; mandibles without an inner comb of teeth. 
Bittacomorpha Westw. (p. 783) 
; Pupae 
Size small (length, excluding breathing horn, under 12 mm.); right breathing horn small, 
degenerate; abdominal tubercles weak, tipped with several strong setae. 
Bittacomorphella Alex. (p. 779) 
Size larger (length, excluding breathing horn, over 14 mm.); right kreathing horn elongate, 
filiform, longer than the body; abdominal tubercles strong, elongate, crowned hy a circlet 
of four or five spines and tipped with a setiferous papilla... Bittacomorpha Westw. (p. 783) 
Genus Bittacomorphella Alexander (Gr. diminutive of Bittacomorpha) 
1916 Bittacomorphella Alex. Proc. Acad. Nat. Sci. Phila., p. 545. 
Larva.— Body short, covered with very prominent projections which are longest on lateral 
and caudal parts of body. Pseudopods prominent, with very large, curved claws. Breathing 
tube short, entirely retractile within body. Head subquadrate, the foramen ventral in 
position; setae of head unbranched. Mandible with an inner comb of teeth. Mentum 
bilobed, cephalic margin untoothed. Coloration black; breathing tube light yellow. 
Pupa.— Right breathing horn very short, degenerate. Fore tarsi overlying middle tarsi. 
Tubercles on abdomen moderately elongated, not crowned by a circlet of spines as in Bitta- 
comorpha, but tipped with a long seta.
