134 HYMENOPTERA FROM SARAWAK. 
PIMPLINI. 
Rhyssa maculipennis, 5m. 
This fine species has been taken at Kuching by Mr. Shelford. 
It varies in size from 20 to 27 mm. and the yellow markings on 
the thorax vary in size and number, as does also the amount 
of black on the legs. 
EKpirhyssa nigrobalteata, sp. nov. 
Luteous; the vertex, occiput, the front broadly in the 
middle except for a square mark in the centre. The mesono- 
tum, except for a squarish mark in the centre, the apical 
slope of the scutellum, a curved line on the apex of the median 
segment, the propleurz: broadly in the middle, the base of the 
mesosternum, an oblique mark on the lower side of the meso- 
pleuree at the base, the base and lower side of the metapleurz 
and the base and apices of the abdominal segments, black. Legs 
coloured like the body ; a line on the femora above, the knees, 
the apical joint of the four front tarsi; the apices of the other 
joints of of the apex of the hinder tibie and the whole of the 
hinder tarsi, black. Wings hyaline, with a faint cloud in the 
apex of the radial cellule; the stigma and nervures black. ©. 
Length 17; terebra 17 mm. 
Hab. Kuching. 
Antennae black, fuscous underneath. Face punctured, trans- 
versely in the centre. Mandibles black. ‘The basal slope of 
the middle lobe of the mesonotum is smooth and has a plum- 
beous hue; so also is the apical slope which is oblique. Scu- 
tellum closely transversely striated in the middle. The middle 
segments of the abdomen are punctured and finely transversely 
striated in the middle. The black basal band on the 2nd and 3rd 
segments are incised in the middie, on the others it becomes 
prolonged down the middle, the prolongation becoming gradu-_ 
ally longer, until on the penultimate segment it extends to the 
apex; on this segment it is of equal width throughout; the last 
segment is entirely black. ‘The recurrent nervure in the fore 
wings is interstitial. 
To Epirhyssa clearly belongs Macrogaster flavopictus Sm. 
(Proc. Linn. Soc. 1857,121) from Singapore.
