ing from the stigma dorsad and a less distinct brown line along the 
ventral margin of the lateral lobe. Gills four in number, pale. The 
sub-caudal enlargement is provided with transverse rows of fine 
hairs or delicate spicules, there being about twenty-five of these 
rows which evidently serve as an aid to propulsion. These rows of 
hairs are much coarser than in related forms (Hcxatoma, about 35 
rows) . The spiracles are circular, situated at the base of the lateral 
lobes. The body is provided with numerous long, appressed hairs. 
A few long hairs or short bristles on the bociy of which the follow- 
ing may be mentioned: One on the latero-dorsal margin of the 
last segment near the base of the lateral lobes; a series of four 
groups of one or two in each across the dorsal surface of the first 
three thoracic segments at about mid-length ; a group of two or three 
long hairs on the sides near the caudal margin of the dorsal seg- 
ments.

Pupa 
Cephalic crest small, depressed, rather inconspicuous, each half 
consisting of three setiferous lobes. The breathing horns (Plate 
IT, Fig. 4) are short and stout, red at the base and apex, the portion 
in between darkened and wrinkled transversely; the enlarged apex 
is very brittle and easily broken off. The mouth parts are about as 
in Erioccra (Plate II, Fig. 6) as figured before (1. c, Plate II, Fig. 
A), but the lobes of the labium are broader and more evenly pen- 
tagonal. The wing-pads extend to just beyond the tip of segment 
two of the abdomen; leg-sheaths extending nearly to the base of the 
fifth abdominal segment; the legs end about on a common level, the 
outer pair very slightly the longer, the inner pair a little the shorter 
of the three. 
Sternites with the basal half feebly wrinkled transversely, the 
caudal half more chitinized and bearing a few weak hairs or slen- 
der spicules arranged as follows: Segment 7, two small bristles 
near the base and closer to the middle line; four small hairs near the 
caudal margin, widely separated. Segments 4 to 6 (Plate II, Fig. 
7) with a sub-caudal row of rather weak slender hairs, this row
