The species is curiously like the African species P. fasci- 
atus, F'., but the genitalia are different. 
A black species distinguished by the wholly black legs 
and by the black abdomen with bushy white hairs on the 
first two segments of abdomen. Moustache yellow below, 
black above. Thorax black with no signs of stripes. Scw- 
tellum with black bristles and hairs. Genitalia of male 
large, the upper forceps with a blunt tooth near the base, 
then becoming concave on their inner edge, and ending in 
a blunt point, under pair short small, all hairs are black 
and numerous. Legs with chiefly black pubescence, some 
yellowish pubescence on the femora. 
Length, g 25-26, 9 23 mm. 
V.d. Wulp gives the length as 19-22 mm.

A male from Sarawak, Borneo, another from Mt. Dulit, 
- Philippines (Everett Coll.), 1901, 247. 
A female from Pasir Ganting, West Coast, Sumatra, 
lat. 2°S., June 1914, 
A female from Irisan, Benquet Province, Luzon. 
V.d. Wulp described a female from Java, de Meijere a 
male and female from Padang, W. of Sumatra. Wulp 
describes the hairs on abdomen as ochre-yellow. De Meijere 
states they are so in the female, but im his male nearly 
white ; he also gives the colour of the legs in both sexes as 
largely reddish, not pitchy brown as v. d. Wulp says, the 
femora being reddish below. 
These specimens in the Brit. Mus. Coll. answer very 
fairly to the description, with the additional remarks by 
de Meijere, so that it seems safe to conclude it is rather a 
variable species with-a wide distribution. 
The hairs on abdomen in both sexes are whitish, tinged 
yellow in the female. Legs dull reddish, femora darker 
above, tarsi all black, and apices of tibiz the same. Palpi 
in male with chiefly black hairs, in female some yellow 
hairs are intermixed. Moustache in male black and yellow, 
in female black sometimes with a few yellow bristles, in 
male the yellow bristles or hairs are a little more numerous. 
A black species distinguished by the white hairs on the 
first three segments of the abdomen, by the partly reddish
