THE CrRANE-FuiEs oF New York — Part II 827 
bark of trees. The material studied was collected by J. R. Malloch in 
Potomac Park, Washington, D. C., on May 11, 1913, and was reared 
by R. C. Shannon (No. 35-1913), whose notes on the subject are as follows: 
A small colony (about seven) of tipulids were found in a hollow of a tree behind the bark. 
The larvae were covered with slime, which gathered débris as they moved about and so 
formed a case. The next morning one had pupated. Two larvae were boiled and pre- 
served in alcohol, while two others were preserved in formal. As they move about they 
leave a path of slime behind them. On May 14, the one that had pupated on the 12th 
emerged. On May 18 another imago issued. 
There is an obvious error in the duration of the pupal stage as given 
— only two days. It is possible that a pupa was included in the material 
and was overlooked in its case of débris. The date of emergence of the 
second adult would show a pupal duration of six days, which is probably 
nearly correct. 
Larva.— Length, 13.2-14 mm. 
Diameter, | mm. 
Coloration white. 
Form terete, rather stout. Sternites 1 to 7 and tergites 2 to 7 with narrow transverse welts 
on basal rings; welts yellow, provided with long, transverse rows of microscopic roughened 
points, those along margins of welts coarser, those in centers very tiny; these rows inter- 
rupted along pleura. Caudal end blunt, with lobes of spiracular disk indistinct. Spiracles 
large, capable of close approximation. 
Head capsule massive, of the Limnobiatype. Labrum (Plate XXX, 121) broadly transverse, 
anterior margin almost straight across, near margin two oval areas which are provided with 
small sensory papillae. Epipharyngeal region with abundant hairs. Mentum (Plate XXX, 
122) chitinized, the anterior margin almost transverse, with a large median tooth and about 
three lateral teeth on either side, the outermost of these an evident fusion of about three lesser 
teeth. Hypopharynx (PlateX XX, 123 and 124) asusualin this subtribe, a collar-like structure 
composed of two parallel combs united at the ends; the larger plate broadly elongate, surface 
with abundant scalelike plates, anterior margin with twelve teeth, the lateral ones narrow, 
the teeth gradually enlarging toward the middie, the middle pair a little shorter; second plate 
of hypopharynx broadly transverse, narrow, likewise with about twelve teeth, the two outer 
most on each side long, subacute, the middle tooth shorter and more flattened; between the 
two middle teeth a small triangular or conical point. Antenna (Plate X XX, 125) short cylin- 
drical, the apical papilla a very flattened disk or button which is much broader than long. 
Mandible (Piate XX X, 126) very broad, flattened, with the apical tooth rather long and slen- 
der; two smaller teeth dorsad and three others ventrad, the dorsal teeth blunt, the ventral 
teeth truncated, the most basal tooth very broad. Maxilla (Plate XXX, 127) of the simple 
generalized structure of this tribe; cardines large, with two setiferous punctures; stipites 
weakly chitinized basally; outer lobe of maxilla with the large flattened palpus at its tips; 
palpus surrounded by numerous long setae and having several hyaline sense pegs at its 
apex; inner lobe of maxilla smaller, with numerous long hairs, especially a slitlike brush 
near margin.
