148 HYMENOPTERA FROM SARAWAK. 
Length 14 mm. 
Hab. Matang. eae 
Antenne black, the 5th to 6th joints white. Face strongly, 
but not very closely, punctured ; the centre above closely trans- 
versely striated ; the clypeus is more sparsely punctured. Man- 
dibles black, broadly pale-yellow at the base. Front irregular- 
ly transversely striated and keeled down the centre. Mesono- 
tum closely rugosely punctured ; the parapsidal furrows trans- 
versely striated ; the apex is more strongly transversely striated. 
The basal area on the median segment is smooth and shining ; 
the rest of the metanotum is coarsely irregularly reticulated 
and punctured. The upper part of the propleure is punc- 
tured in front, striated behind; the lower part is stoutly 
distinctly striated. Mesopleurse strongly and closely striated; 
obliquely below, more irregularly at the base above. Meta- 
pleure irregularly obliquely striated. Post-petiole irregularly 
punctured, the 2nd and 3rd segments closely and regulary punc- 
tured. . 
May be known from S. flavipes by the large yellow mark on 
the mesopleuree, by the yellow mesosternum, by the mark on 
the mesonotum, by the rufous hinder tibie, by the yellow line 
on the metanotum, being semicircular, not transverse, etc. It is 
a much more robust species. 
Skeatia carinata, sp. nov. 
Black ; the face, clypeus, inner orbits narrowly, the malar 
space, the pleure, the scutellum, post- scutellum, the space at 
their sides, the apical slope of the metanotum, a semicircular 
mark in the middle above it, the spines and the apices of the ab- 
dominal segments, yellow ; the four front legs pale yellow ; the 
hinder legs black, their coxe for the greater part yellow, the 
tarsi white ; the wings hyaline, the nervures and stigma black. ©.
