Mr. P. Cameron on new Hymenoptera. 121 
segment alutaceous; the apex obscurely transversely striated, 
and with a smooth conical depression in the middle. Legs 
thickly covered with golden pubescence, more thickly on the 
tibiz and tarsi than on the femora; there are five rows of 
stout rufous spines on the four hinder tibie; the tarsal spines 
are long, stout, and rufous. Wings yellowish hyaline, the 
apex from the base of the radial cellule infuscated ; the first 
cubital cellule at the top is not quite half the length of the 
second ;° the first transverse cubital nervure is obliquely 
curved from shortly above the middleand straight; the lower 
part has a more rounded slope; the two recurrent nervures 
are received near the apex of the basal third of the cellule. 
The three basal segments (and perhaps the others also) are 
banded at the apex with depressed pale golden pile. The 
pygidium appears stoutly, longitudinally, and closely striated 
and bears some longish dark rufous hairs. The tarsi have 
a more rufous appearance than the tibie; the golden pile 
appears to be thicker on the front legs than on the others. 
Chrysolarra pruinosa, sp. n. 
Black, thickly covered with a pale golden pile, the py- 
gidium densely with stiff golden. bristles; wings hyaline, 
slightly infuscated at the apex ; the third cubital cellule above 
twice the length of the second ; the recurrent nervures united, 
but not appendiculated. ¢.

flab. Matang, Borneo. Mus. Sarawak. 
The lower part of the front, the face, and probably the 
clypeus densely covered with a golden pale pile. Front and 
vertex alutaceous ; there is a deep furrow below the lower 
ocellus ; the eyes at the top are separated by about half the 
length of the third antennal joint. Thorax covered with a 
golden pile; the scutellum has an indistinct shallow furrow 
in the centre ; the median segment at the base has a narrow 
furrow down the middle, which ends in a fovea shortly before 
the top of the truncation. The latter has an oblique slope 
and has a narrow furrow in the centre. ‘There is a narrow 
longitudinal furrow near the centre of the mesopleure. 
Wings hyaline, with a slight yellowish tinge; the apex 
slightly infuscated; the basal nervures are yellowish, the 
apical darker in colour; the second cubital nervure is half 
the length of the third; the recurrent nervures are united and 
are received shortly behind the middle of the cellule, Legs 
black, pruinose; the tibial and tarsal spines are black, some 
of the latter are rufous at the base, those on the front tarsi
