64 SPOLIA ZEYLANICA. 
vertex with two broad brownish longitudinal streaks, leaving free 
only a very fine yellowish line along the suture. Temples absent. 
Eyes relatively small, not prominent, hairless, brownish, with red- 
golden sheen. Cheeks strongly arched, expanding below, whitish 
yellow. Clypeus relatively small, set off by a fine groove, slightly 
convex. Clypeolus narrow, pale. Upper lipsmooth, black. Maxil- 
lary palp pale yellowish, end joint slender and brown ; second joint 
with two spurs, third with three, fourth with two strong “and 
relatively long spurs. 
Ocelli (fig. 34) very small, the anterior ocellus half the diameter 
of the posterior ocelli ; the interval between the latter about half 
as great as the interval between them and the eye-borders. Suture 
between forehead and vertex absent. 
Antenne thin, about three-fourths the length of the fore wing, 
brown, the three first joints clear brownish yellow, fairly closely and 
fairly long pubescent, at the base chiefly pubescent in front only 
(probably all specimens female). Inner lobe of maxilla represented 
in fig. 112. 
Mesothorax brown above, beset with gray scales which have 
mostly dropped off. Abdomen of dried specimens brown. Legs 
clear brownish yellow to whitish yellow. The following parts are 
dark brown :—The extreme upper apex of the femora; the tibie 
with exception of the apex and of a ring in the middle, in the hind 
tibiz with exception of the base also ; the first tarsal joints except 
the apical third in the fore leg, and the apical half and more in the 
middle and hind legs. Femora little expanded, the hind femora 
not expanded. Hind tibie with a great number of almost upright, 
short (long in comparison with syllysis, &c.) spurs which are dis- 
tributed on all sides of the tibia. The length of the anterior tibia 
is 0-57 mm., of the middle 0°63 mm., and of the posterior tibia 
1:23 mm. Claws (fig. 56) slender with two teeth before the apex 
and inwardly outside the edge with fine hairs. The length of the 
first, second, and third fore tarsal joints respectively is 0°42 mm., 
0:08 mm., 0°01 mm. ; of the mid tarsal joints 0°45 mm. 0:07 mm., 
0:09 mm. ; of the hind tarsal joints 0°85 mm. ;0°1 mm. 0°14 m.m. 
The ratio of the hind tarsal joints is therefore as 84: 1:12. First 
hind tarsal joint with about 27 ctenidiobothria. Femora, tibiz, 
and first tarsal joints scaly. 
The closure of the pterostigma fails through the absence of the 
distal piece of the subcosta (fig. 27). Stigma sac well developed, 
short and thick. Membrane of fore wing brown, apical angle almost 
hyaline. Veins brown, those of the apical third dark brown. 
In consequence of the scaling, a gray silver ground colour is present,
