narrow dark scaling. Each of the following 
pleural areas with a patch of broad pale scales : 
propleural, postspiracular (few or none), para- 
tergite (few or none), dorsal sternopleural, 
ventroposterior sternopleural, and mesepim- 
eral. Legs: Fore and mid-femora dark ante- 
riorly, hind with anterior surface pale except 
for apical fourth and most of dorsal margin, 
a line of pale scales anteriorly on apex of hind 
and mid femur. Tibiae and tarsi dark. Tarsal 
claws equal, fore and mid unidentate, hind 
simple. Wings: Dark-scaled. Halter knob with 
dusky scaling. Abdomen: Tergites dorsally 
dark, basolateral pale scaling on I-VII, this 
visible dorsally on II-VI. Sternites III-VII 
with basal pale bands. 
larva: Undescribed. 
BIONOMICS: The single adult from Palawan 
was netted in a densely shaded area near a 
river. No larvae were found in the Philippines. 
Leicester (1908: 193) collected larvae from 
jungle pools in Malaya. Further, he reported 
the female to be a vicious daytime biter. 
DISTRIBUTION: Specimens examined. R.K.L. 
Palawan: 1 female, Bacungan (Lalfoon). 
C.A.S. Mindoro: 3 females, San Jose (Ross). 
Literature records. Mindanao: Ft. Pikit (type 
series of ^^gV). 
Outside the Philippines, reported from In- 
dia, Ceylon, Malaya, Indo-China, Sumatra, 
Java, Borneo, and Ceram. 
discussion: The Palawan female was com- 
pared with Leicester’s two cotype females in 
the British Museum. It was found to agree 
sufficiently well to be considered conspecific. 
Theobald’s type female of chrysoscuta was 
examined and found to agree well with the 
Palawan specimen except that the pleurae are 
noticeably paler in color.

ADULT: A dark-brown species, with a broad 
median silvery line on anterior half of scutum, 
broad silvery scales on the paratergite, mid- 
scutellar lobe, and torus. Hind tarsi banded 
with white. 
Male. Unknown. 
Female. Modified from the original descrip- 
tion, Head: Proboscis dark brown, nearly as 
long as fore femur. Palpus about one-sixth 
length of proboscis, dark brown. Torus dark 
brown, with a small patch of broad silvery 
scales medially. Vertex broad-scaled, a tri- 
angular silvery patch medially that broadens 
anteriorly and extends on either side as a short 
fine line along the eyes, laterad to this median 
area is a dark-scaled spot, the remainder of 
the dorsal surface and the entire lateral surface 
pale brownish (almost whitish under different 
lighting), a median area of narrow dark scales 
and a few upright-forked dark scales on the 
nape. Thorax: Integument brownish on scu- 
tum, darker on pleurae. Scutal scales narrow 
dark brown; a broad median silvery line on 
the anterior half of the scutum; a pair of 
dorsocentral bristles anteriorly and a stronger 
pair above level of wing bases, two pairs of 
prescutellars, rather few supra-alars. Scutel- 
lum with broad scales, silvery on mid-lobe 
except for a narrow dark line on posterior 
margin, dark on lateral lobes. Apn with a small 
patch of silvery flat scales; ppn without scales, 
3 bristles present. Each of the following pleu- 
ral areas with a patch of broad silvery scales : 
propleural, subspiracular, paratergite (cover- 
ing entire area), upper sternopleural, medio- 
posterior sternopleural, and upper mesepim- 
eral. Legs: Dark brown. Femora pale basally 
and below, hind with basal half pale both 
anteriorly and posteriorly, mid and hind with 
a conspicuous silvery spot at apex. Fore and 
mid-tarsi with a basal white band on I, re- 
mainder dark. Hind tarsus with a basal white 
band on I, remainder missing. Wings: Dark.
