THe CrANE-F LIES oF NEw York — Part II 1007 
conditions are discussed more fully under the account of Rhamphidia 
(page 831). The larvae are reddish brown in color, and rather sluggish. 
One of the larvae found on April 20 pupated on the 22d and emerged as 
an adult female on the 30th, a pupal duration of eight days. An additional 
pupa was taken, associated with larva of Pseudolimnophila luteipennis, 
P. inornata, Tricyphona inconstans, and other species. 
Larva.— Length, 20 mm. 
Diameter, 1.8 mm. 
Coloration brown; dorsum marked with light and dark brown; a narrow, indistinct, dark 
brown, median line, with a broader zigzag brown line on either side; ventral surface a little 
paler. 
Body covered with a short, dark pubescence at sides of segments, at margins longer and 
more conspicuous. Chaetotaxy as follows: tergites with six strong setae in transverse 
alinement, the outermost in pairs; two strong setae on each pleural annulus; posterior ring 
of sternites with eight strong setae, arranged in four pairs. Spiracular disk (Plate XCV, 
526) pale, surrounded by six approximately equal lobes which are heavily marked with 
brown; dorsal and lateral pairs pointed, ventral pair blunt; ventral lobes with apical half 
shiny black, on ventral inner margin continued dorsad, almost contiguous on midline; inner 
face of dorsal and lateral lobes suffused with dark brown, proximal margin of dorsal lobe 
roduced inward so that the marks are almost contiguous on median line; beneath each 
piracle a transversely rectangular, dark brown mark. Anal gills with four anterior lobes 
hich are long and slender, and a pair of rudimentary blunt posterior gills (Plate XCII, 509). 
Head capsule and mouth parts as in genus. Mentum (Plate XCV, 524) seven-toothed, 
pical point the longest. Hypopharynx (Plate XCV, 525) bluntly five-toothed. 
Pupa.— Length, 15.3 mm. 
Width, d.-s., 2.3-2.4 mm. 
Depth, d.-v., 2.1-2.2 mm. 
Coloration dark brown; abdominal incisures paler. 
Form relatively stout. General features as in genus. Cephalic crest consisting of two 
lunt lobes with microscopic setae. Maxillary palpi strongly curved at tip, but not entirely 
ecurved. Pronotal breathing horns short, tips a little enlarged. 
Abdominal tergites with spines weak, on median area of each row weak or lacking; on 
ntermediate segments about fifteen spines; pleurites with only a single weak spine on basal 
ing; on posterior ring a rudimentary anterior spine and a somewhat larger posterior spine; 
ternites similarly armed to tergites, but spines fewer in number and larger, on segment 
about twelve in number; on base of posterior ring a large spine on either side median line 
nd a small setiferous tubercle laterad of each. Female cauda with tergal valves of ovi- 
ositor long and straight, sternal valves a little shorter; cauda with the usual six dorsal lobes, 
hese terminating in slender spines; at end of eighth sternite six large spines; dorsal spines 
educed to a single small pair, one near each lateral margin. 
Nepionotype.— Larch Meadows, Ithaca, New York, April 20, 1917. 
Neanotype.— With type. 
Paratypes.— Two pupae with type pupa.
