THE CrRANE-Furrs of New York — Part II 851 
type; tips blunt, ending in two large approximated teeth, with a row of smaller lateral teeth 
extending basad of each; ventral cutting edge with about four such lateral teeth, dorsal edge 
with one or two much larger teeth; two strong setae near base of scrobe, and two others near 
tip of mandible; a large brusk of hairs at prosthecal region. Maxiila not projecting, with 
dense brushes of short, stiff hairs and with two short sensory tubercles which are tipped with 
very elongate setae; palpi stout and chitinized at base, the apex narrowed and pale. 
Pupa.— Length, 10-13 mm. 
Width, d.-s., about 1.5 mm. 
Thorax reddish brown to black in cclor, depending on age of specimen; abdomen dirty 
whitish with narrow transverse brownish lines, both above and below; pronotal breathing 
horns dark brown or blackish. 
Form subeylindrical, abdomen slightiy depressed. Cephalic crest of two slender tubercles 
behind, tipped with long setae; another pair of setae between antennal bases. Pronotal 
breathing horns elongate, transversely ringed, the tips widely and deeply split into two 
divergent flaps. Prothorax with:a prominent median carina. A tubercle in front of each 
breathing horn, each with about four stout setae. Mesonotum above wing axil with a 
tubercle bearing three setae. Wings reaching end of second abdominal segment. Legs 
reaching end of third abdominal segment, the tarsi ending about on a level or those of fore 
legs a little longer than those of other two pairs. 
Abdominal segments divided into two annuli, the basal one still further subdivided into 
annulets; on tergum three annulets, each bearing a transverse row of setiferous tubercles, the 
setae very long and conspicuous, in some cases the tubercles multisetose, third annulet 
with two widely separated, slender, elongate tubercles. Posterior annulus with a basal 
and a terminal transverse row of setiferous tubercles. On sternum, four transverse rows of 
setiferous tubercles on basal ring and two on posterior ring. On pleura, protuberant spiracles. 
Lateral angles of segment 8 jutting out into stout lobes which are densely studded with 
setiferous tubercles, on ventral face continued toward median line as a nearly straight row 
of about eight setiferous tubercles, on dorsum a finger-like lobe on either side: Male cauda 
(Plate XL, 178) with sternal valves shorter than dorsal lobes, blunt at tips; tergal valves 
acutely pointed, directed dorsad. Female cauda (Plate XL, 179 and 180) with tergal valves 
considerably longer than the more slender sternal valves, broad medially, tapering to the 
broad, blunt tips which terminate in blackened points; two setae on outer margin.

1869 Limnophila inornata O. S. Mon. Dipt. N. Amer., part 4, p. 219, 220. 
Pseudolimnophila inornata is not so common as P. luteipennis but is 
found in similar situations. The immature stages are spent in rich organic 
mud. The only specimens that the writer has reared were taken in
