Pilaria tenuipes is a widely distributed crane-fly thruout eastern North 
America. The immature stages are commonly found in the mud of 
swamps, or near streams and other bodies of water. This is the unknown 
Limnophila described by Hart (1898 [1895]: 204-205), and also considered 
in much detail by Malloch (1915-17 b: 223-224), who found the pupae 
along the banks of the Sangamon River in Illinois. 
Larva.— Length, 16 mm. 
Diameter, 1.4-1.5 mm. 
Coloration of living larva, pale brownish yellow. Body covered with a long, dark-colored, 
appresséd pubescence, more conspicuous on posterior segments. Lateral pencils of setae 
near base and apex of segments. Antepenultimate segment of body capable of globular 
distention, covered with numerous transverse rows of microscopic roughened points. 
Spiracular disk (Plate XLVIII, 230) moderately large, surrounded by four lobes; ventral 
lobes long and slender, inner face with closely approximated, transverse, brownish black lines 
which cause entire face to appear dark; near tips of lobes these black marks tapering out 
into a long point; basal parts of dark marks subcontiguously hollowed out interiorly to form 
a large pale area below spiracles; ventral lobes fringed with long, pale hairs, some of them 
exceedingly elongate. Lateral lobes very small, blunt, tending to be reduced, bearing short 
fringes of dark hairs. Anal gills slender, pale in color. 
Head capsule of Ulomorpha type and not very different from that of the type genus; 
dorsal plate broad basally, narrowed gradually behind to near tip where it expands into 
a very large spatula. Epipharyngeal region of labrum and maxillae fringed with dense tufts 
and brushes of long yellow hairs. Maxillary lobe relatively small but elongate, hyaline, 
tapering to flattened apex. Antenna (Plate XLVIII, 229) with basal segment elongate, 
bearing at its tip an elongate apical papilla which is a little longer than the segment, bluntly 
rounded at its tip, and delicately sculptured. Mandible (Plate XLVIII, 228) very long, 
hinged, at its base an acute tooth equal in length to about one-third length of mandible; in 
the type larva, the left mandible a little longer than the right mandible. Mental region 
not chitinized. 
Pupa.— Length, 10-15 mm. 
Width, d-s., 1.5-1.6 mm. 
Depth, d.-v., 1.6-1.8 mm. 
Coloration dark brown; pronotal breathing horns light yellow, extreme bases brownish. 
Cephalic crest small, composed of three slender, finger-like lobes which are tipped with 
strong setae; on front, before crest, two setiferous lobes. Labrum small, bluntly rounded
