THE CRANE-F LIES oF NEw York — Part II 1011 
Coloration grayish brown, paler gray beneath; thoracic segments conspicuously reddish 
TOWN. 
Body terete. Dorsum covered with a short, dark pubescence, which gives upper surface 
ts dark color. Chaetotaxy as follows: tergites (Plate XCVI, 530) with a posterior trans- 
rerse row of two setae near base of posterior ring; sternites (Plate XCVI, 531) with about 
ight setae, anterior median row consisting of two large setae, each with a tiny seta 
yroximad of it, the posterior pair of large setae more widely separated, lateradof each of these 
wo closely approximated smaller setae. Spiracular disk (Plate XCVI, 532) surrounded 
y six moderately long lobes fringed with rather short, pale hairs; tips of ventral lobes with 
pale circular area provided with a sensory seta; inner face of spiracular disk with the 
arkings pale, ventral lobes with an indistinct capillary brown line; two brown spots beneath 
ach spiracle. Spiracles large. Anal gills eight, consisting of a transverse row of four 
hort, slender, two-branched lobes (Plate XCII, 511). 
Mentum of head capsule with median point prominent, the three lateral teeth of either 
ide small, moderately acute. Mandible with about four teeth, in addition to the large 
asal prosthecal tooth. 
Pupa— Length: male, 12 mm.; female, 14-15 mm. 
Width, d.-s.: male, 1.7-1.8 mm.; female, 1.8-2 mm. 
Depth, d.-v.: male, 1.9-2 mm.; female, 2.1-2.2 mm. 
Head and mouth parts as in genus. Pronotal breathing horns rather long and slender, 
ps a little expanded. leg sheaths rather short, just exceeding third abdominal segment; 
ind legs a little the longest, the other tarsi ending about on a level. 
Abdominal tergites with armature weak, spines small; pleurites and sternites with spines 
otably larger and more powerful; sternites with subterminal row consisting of twelve to 
teen spines, those of the sixth and seventh segments larger; no spines at base of posterior 
ng; pleural spines setiferous, very weak, one on basal ring, two on posterior ring. Male 
uda with ventral lobes widely separated, terminating in slender, curved spines directed 
udad; dorsal lobes slender, approximated on dorso-median line. Female cauda (Plate 
CVI, 533) with tergal valves a little longer than sternal valves, the latter at their tips 
rminating in slender points directed ventrad and laterad; dorsum of cauda with the usual 
lobes, posterior pair the largest, terminating in two distinct points; eighth segment on 
eural and sternal region with six very powerful, curved spines.

ipula abdominalis (Say) 
1823 Ctenophora abdominalis Say. Journ. Acad. Nat. Sci. Phila., vol. 3, p. 18. 
Tipula abdominalis is the largest eastern species of the genus, altho 
me specimens of 7’. caloptera are nearly as large. The adult flies are 
the wing in late August and September, and even, in fewer numbers, 
June and July.
