THE CRANE-FuiEsS oF New York — Parr II 855 
can be found in myriads by sweeping the rank herbage in May. The 
writer has never located the immature stages, but the species was reared 
by Dr. J. G. Needham at Ithaca, New York, on May 20, 1898. There 
is no record as to where these larvae occurred, but they are presumably 
mud-inhabiting forms, or possibly they frequent habitats similar to those 
described for the two preceding species. 
Pupa.— Length of cast skin, about 12 mm. 
Pronotal breathing horns (Plate XLI, 187) short, cylindrical, the tips saree enlarged. 
Mesonotum behind with a prominent rounded tubercle on either side of median line, which 
is set with two spines, a larger outer spine and a small inner spine. Wing sheaths ending 
Opposite apex of second abdominal segment. Leg sheaths ending opposite apex of third 
abdominal segment, the tarsal sheaths terminating on a common level. 
Abdominal segments divided into two rings. Tergites with posterior ring having a 
transverse row of elongate tubercles, there being about eight on segment 2, about six on 
intermediate segments (3 to 5), and about four on segments 6 and 7; these tubercles fleshy, 
but sparsely armed with chitinized spines. Basal ring unarmed. Pleura with a strong 
tubercle on each ring; a blunt but prominent spiracle at extreme base of posterior ring; this 
spiracle very prominent on segment 2 (Plate XLI, 188), much exceeding lateral tubercles 
and being about two-fifths length of pronotal breathing horns. Sternites with about six 
tubercles on posterior ring. Male cauda (Plate XLI, 189) with tergal lobes slender, running 
out into acute chitinized points, which are directed caudad, slightly divergent; dorsum of 
segment 8 with posterior lobes powerful, about equal in size to, or a little larger than, tergal — 
lobes of cauda just described; anterior lobes small, directed caudad and laterad; two large 
lateral lobes and two smaller ventral lobes. Female cauda with tergal valves moderately 
elongate, stout, broad at base, narrowed toward tip, where they run out into long,.chitinized 
points directed caudad and slightly dorsad. 
Neanotype.— Cast pupal skin, Ithaca, New York, May 20, 1898. 
Paratype.— Pupae, cast skins, with type.

1859 Limnophila montana O.S. Proc. Acad. Nat. Sci. Phila., p. 240-~ _ 
The species Dactylolabis montana is common and widely distributed 
thruout the northern United States. It is a characteristic inhabitant of 
rocky cliffs, where it rests in crevices on the almost vertical walls. The 
immature stages have long remained unknown, but during the spring 
of 1920 W. L. McAtee found a pupal skin and the teneral adult near 
Washington, D. C. Mr. McAtee writes that the pupa was found in the 
moss that covers the almost vertical north face of a cliff on Plummers 
Island; this moss is mostly shaded, and grows on a thin layer of black soil 
which, at that time of the year at least, is saturated with water. The
