HYMENOPTERA FROM SARAWAK. 145 
punctured, more strongly on the basal than on the apical seg- 
ments; the depressions are minutely striated. The ventral surface 
is pale brick-coloured. The front legs are dark rufous, the 
trochanters and tarsi darker coloured; the tibie have a pale yel- 
low streak in front; the middle femora are bright rufous in 
front, dark behind. 
Lethulia, gen. nov. 
Areolet absent: the recurrent nervure united with the 
transverse cubital. Antenne long and slender, the flagellum 
broadly ringed with white. Head cubital ; the occiput margin- 
ed, temples large, the malar space wide. Clypeus clearly sep- 
arated from the face, depressed, its apex transverse and with 
a distinct margin, below which it is obliquely depressed. Man- 
dibles broad; they have a short blunt subapical tooth. Parap- 
sidal furrows wide, deep, the mesonotum distinctly trilobate. 
Metanotum with 3 distinct arez at the base; spiracles linear, 
placed distinctly behind the middle. The hind Jegs longer than 
the others; their coxe large, their trochanters long and dis- 
tinctly narrower than the femora which are stouter than usual ; 
their tibiz are much longer than them; calcaria short; the 2 
hinder claws are simple. The anterior tarsi are twice the length 
of the tibiz ; their claws and those of the middle bifid; the ba- 
sal joint of all the tarsi is shorter than the 4 following united. 
If any thing, the recurrent nervure is received on the outer side 
of the transverse cubital ; there is uo stump of a nervure on the 
cubito-disco nervure, 
This genus comes near to Fis/istina; it may be known 
from it by the transverse, not rounded, apex of the clypeus and 
by its being clearly separated from the face, by the antenne 
being loner, more slender and broadly ringed with white, by 
the very long hinder trochanters, by the petiole being more 
slender and longer than the 2 following segments nnited and 
by the hinder tibiae being much longer compared with the tarsi. 
Lethulia flavipes, sp. nov. 
Black, the legs yellow, with the hinder coxe and femora 
black ; the antennz white, broadly black at the base and apex;
