THE CrRANE-F Lies or NEw York — Part II 811 
skin splits down the dorsum, the pupal skin remaining in place after the 
adults have emerged. 
On September 15, 1912, many full-grown larvae were found in a fleshy 
species of Fomes near Gloversville, New York, where they were asso- 
ciated with a much larger number of larvae of Ula elegans and a much 
lesser number of Limnobia triocellata. When about to pupate, the larva 
becomes pale green in color and incases itself completely in a silken sheath 
which is covered with particles of sand and other débris. As the pupa 
erows older, the case becomes harder and more rigid. Numerous little 
mites are to be found running up and down over these pupae, more 
especially at the head end, and possibly seeking ingress into the insect. 
One young pupa had a piece of cloth adhering to the side of its case. The 
pupal stage lasts about five days. 
Larva.— Length, 18-22 mm. 
Diameter, 2.5-8.2 mm. 
Coloration light yellow to greenish, the setiferous transverse welts at base of abdominal 
segments brownish. 
Body terete, abdominal segments subdivided into two narrow basal rings and a broad 
posterior ring. Abdominal segments 1 to 7 with a broad basal welt on tergites and sternites, 
that of the first segment much smaller; these welts densely covered with microscopic hooks; 
on the last two thoracic segments, welts indicated by very narrow lines. Cauda blunt, 
obliquely truncated. Spiracular disk (Plate XXIV, 83, and Plate XXV, 93) surrounded 
by indistinct lobes, the ventral margin projecting far caudad and indistinctly divided into 
two short lobes; lateral lobes very blunt; dorsal lobes short and blunt, often divided into 
two smailer lobes. Spiracles oblong or elliptical, placed obliquely. Gills four, blunt and 
rounded, formed for propulsion rather than for respiration. 
Head capsule (Plate X XIV, 79) very muchas in Antocha, the dorsal plate narrowed behind 
and somewhat bifid at apex; lateral plates shaped like a mussel shell, curved around to form 
mentum. Labrum (Plate XXV, 86) distinct, oval, the anterior margin fringed with delicate 
hairs, the hairs at the lateral margins longer and coarser; on either side near anterior margin, 
a blunt tubercle with three sensory bristles; just laterad of this a stout seta; along anterior 
margin, four sensory setae which are subequally spaced. Epipharynx densely hairy. 
Clypeus broader than labrum, with a seta at each outer anterior angle and two more on 
either side near posterior margin. Mentum (Plate X XIV, 81) elongate-triangular, not com- 
pletely divided into halves but deeply split behind, with an outer plate running cephalad into 
a long, broad point; behind this another plate with the margins toothed, there being about 
five or six long, acute teeth on either side. Hypopharynx (Plate XXIV, 80) with two 
rows of teeth forming a circlet, into which duct of salivary gland opens; anterior row having 
about nine large, blunt teeth, with about six smaller teeth on either side, these latter sharper- 
pointed and more crowded; posterior row having long, pointed teeth, about twelve in 
number. Antenna (Plate XXIV, 82) two-segmented, the basal segment chitinized, elongate-
