Tue CRANE-FiIES oF NEw York — Part II 783 
slenderest; a dorsal line of strong setae extending from base of outer hook inward; outer 
edge of mandible with two strong setae, these protected at their bases by small dorsal ears, 
or projections, from the mandible; dorsal face of mandible with a powerful hinged prostheca; 
near base of mandible on dorsal face a curious five-lobed sensory organ. Maxilla (Plate 
XVI, 29) with the cardo triangular, the ventral or outer face with two closely approximated 
setiferous punctures; stipes triangular, with three strong setae near palpus; palpus 
antenniform, cylindrical, rather elongated, and with about six sensory papillae at tip, 
one being much longer than the others; outer lobe of maxilla with cephalic margin blackened 
and chitinized, inner angle with a dense brush of long hairs. 
Pupa.— Length excluding breathing horn, 9.5 mm. 
Width, d.-s., 1.7 mm. 
Depth, d.-v., 1.4 mm. 
The following description is taken from the cast pupal skin of the only 
specimen that was reared: 
Antennal bases approximated on front between eyes. Clypeus bluntly rounded at apex, 
transversely wrinkled. Lobes of labium (Plate XVII, 36) broad, rounded apically; maxillary 
palpi short and stout, broad at base, gradually narrowed to the short tip, which is not 
recurved. (The structure of the head and the eyes indicates some peculiar characters not 
possessed by the pupae of related genera, but the cast pupal skin is insufficient for accurate 
diagnosis.) Two bristles below eye and just above base of palpus, and a Jonger and more 
slender seta farther laterad. Sides of head behind antennae appear to be produced laterad 
into blunt points. Right breathing horn small, degenerate, much curved. (In the single 
pupal skin available, it cannot be determined whether the left horn has been broken off or is 
undeveloped.) Just laterad of each breathing horn a small tubercle bearing a long seta. 
Scutal lobes with about four stout setae. Tarsal sheaths of fore legs, as in the subfamily, 
overlying the middle pair but shorter (Plate XVII, 37). 
Abdomen with chitinized bands extensive, as in Bittacomorpha. Arrangement of tubercles 
about as in other species of family. Tubercles shorter and weaker than in Bittacomorpha 
and not crowned by a circlet of spines, each being tipped with one or more (four or five) long 
setae (Plate XVII, 38); the pleural tubercles the longer and many of them multisetose. 
Cauda of male, in general’ features, similar to that in Bittacomorpha, the dorsal median 
lobe (Flate XVII, 39) stout, the ventral horns (Plate XVII, 40) short and powerful, 
irected laterad; horns on dorsal lobes apparently lacking.

Larva.— Form elongate, body gradually narrowed behind into the partly retractile
