THe CrANE-FiIES oF New York — Part II 905 
is given in connection with the discussion of Rhamphidia mainensis 
(page 831). 
Larva.— Length, 17-17.5 mm. 
Diameter, 1.3 mm. 
Color pale yellowish white; anterior parts of body sometimes a more saturated yellow. 
orm moderately stout, body a little narrowed toward ends; surface of body almost 
labrous, the vestiture being a microscopic pale pubescence and scanty scattered hairs. 
entral surface of abdominal segments 4 to 7 with a prominent transverse welt, which is 
ollowed out medially so as to appear as paired prolegs, these being unarmed with hooks 
r points. Spiracular lobes short, divergent, tapering gradually to the blunt tips, which are 
rovided with seven or eight setae. Spiracles (Plate LXIII, 330) on a transverse oval eleva- 
ion, small, rounded, separated by a distance greater than diameter of one; middle piece of 
piracles large, black, rings narrow. Anal gills four, very long and slender, constricted 
to about four lobes which are successively narrowed from the base outward, the terminal 
ivision very slender. 
Head capsule of the usual elongate, massive type of this tribe. Labrum large, projecting 
eyond hypopharynx, anterior margin with long hairs. Mentum (Plate LXIII, 326) large, 
ompletely divided, each half with three subequal narrow teeth and an additional reduced 
teral tooth; on proximal margin of each half of mentum, near base of innermost tooth, 
few tiny notches dovetailing into those of opposite half. Hypopharynx (Plate LXIII, 327) 
rojecting far beyond mentum, labriform; anterior margin deeply concave and provided with 
ali rounded papillae; lateral angles smooth, rounded, subchitinized. Antenna (Plate 
XIII, 328) small; basal segment cylindrical, bearing at its tip two elongate papillae which 
re about one-half longer than basal segment alone; besides these an oval papilla. Mandible 
late LXIII, 329) of the usual pediciine type, powerful, the apex running out in a long, 
ved point; ventral cutting edge very flat, cut into about five teeth, the two basal of which 
e very large; the most basal of these teeth squarely truncated, the left mandible with an 
dditional small tooth on lower inner angle of this blade; the next outer tooth rather acute; 
termost teeth small and flattened; dorsal cutting edge, as usual with this division, with 
0 very small teeth located far out on apical point; a tuft of a few long setae on back of 
andible near heel. Maxilla (Plate LXIII, 329) powerful, as in this group of genera, 
t not exserted from the prothoracic orifice when head is retracted; outer lobe very 
ut, feebly chitinized basally, hyaline at apex, which bears the flattened, disklike palpus; 
er lobe slenderer, shorter, with a few setae and small papillae. 
Pupa.— (The following notes are taken from the cast skins of the reared specimens.) 
Labrum with apex broadly triangular. Labial lobes large, ovate, tips narrowed and 
untly rounded (Plate LXIII, 331). Pronotal breathing horns (Plate LXIII, 332 and 333) 
ry short, stout, roughly cylindricai, the apices truncated; in lateral outline, pentagonal, 
ith a row of breathing pores around margin of truncate apex. Thoracic dorsum trans- 
rsely roughened by short, irregular grooves. 
Abdominal sternites with broad transverse bands of spicules on segments 5 to 7, the last 
these three bands the weakest; similar bands on tergites 4 and 5, these bands subequal 
| size; pleural region with a large, roughly circular area of short rows of microscopic spicules,
