THe CrRANE-FiIeEs oF New York — Part II 903 
slightly flattened, with a row of circular breathing pores along margin of distal end, which 
is slightly enlarged. Wing sheaths short. Leg sheaths much longer. 
Pleural region of abdominal segments with circular areas which are armed with abundant, 
short, straight or slightly arcuated, rows of spicules, there being from five to seven spicules 
in each row; under high magnification these appearing as flattened, scalelike tubercles, 
fringed with the spicules described above; dorsum of intermediate abdominal segments 
with a broad transverse band which is-rather densely set with tiny, sharply curved spines; 
on postericr segments these rows lacking or much weaker; dorsal bands lying posterior to 
level of lateral areas. Male cauda (Plate LXII, 325) with dorsal plate rather small, each 
half indistinctly bilobed at tip; outer lobe minutely tuberculate and with a small seta; 
ventral lobes large, blunt at tips; eighth tergite on either side with a small tubercle bearing 
two setae. ;

Larva.— Body moderately elongate, with ventral transverse creeping-welts on basal annuli 
of abdominal segments 4 to 7. Spiracular lobes two, moderately elongate. Anal gills four, 
divided into two to four lobes by from one to three constrictions. Head capsule massive, 
elongate. Eyespots distinct. Mandible powerful, ending in an acute point and with about 
four lateral teeth. Maxilla stout, consisting of two distinct lobes, the slender inner lobe 
closely approximated to the larger outer lobe. Antenna small; basal segment cylindrical 
at tip, with two exceedingly long, hyaline papillae (possibly lacking in 7. immaculata). 
Hypopharynx labriform, anterior margin concave, roughened. Mentum completely divided, 
anterior margin of each half with three large teeth. 
Pupa.— Pronotal breathing horns short and stout, blunt, angles rounded. Abdominal 
segments with transverse bands of spicules on tergites and sternites, and circular areas 
on pleurites. 
Tricyphona is the largest genus of the Pediciini, including more than 
fifty described species. Almost all of these species are found in the 
Holarctic region, but two or three are Antipodal. In the eastern United 
States, Tricyphona inconstans is the most widely distributed and appar- 
ently the commonest species. This species and certain others (as 7. 
paludicola Alex.) are characteristic swamp inhabitants, but other species
