HYMENOPTERA FROM SARAWAK, 161 
Ampulex rufo-femorata, Sp. Nov 
Green; largely marked with blue, the pleure with brassy 
tints ; the antenne black, the 3rd joint about one half longer 
than the 4th; the temples sharply obliquely narrowed; meta- . 
notum closely transversely striated ; all its keels reach close to 
the apex of the segment; the central one bifurcates obliquely at 
the apex, the end keels uniting to the apex of the 3rd_ keel; all 
the trochanters and femora and the fore tibiz are red; the tarsi 
black ; the wings infuscated; the apical third darker cloured ; the 
1st transverse cubital nervures obliterated; the 3rd is receiv- — 
ed at a short distance from the apex of the radius; the 2nd seg- 
ment is distinctly longer than all the following united ; at its base 
below it has a rounded oblique slope. @. 
Length 14 mm. 
Hab. Mount Sibou. 
Front and vertex sparsely punctured ; the latter depressed 
broadly in the middle; the inner orbits are marzined ; the keels 
leading into the antenne are long, stout and oblique; between 
them, below, are some curved furrows: the eyes atthe top are 
separated by the length of the antennal scape and pedicle united. 
The raised part of the pronotum is shortly, but distinctly, longer 
than its breadth at the apex and is slightly narrowed at the base. 
The metanotum is not much shorter than the mesonotum; its 
teeth are stout and long ; its apical slope is covered, except in 
the centre above, closely with curved striz and is thickly 
covered with white pubescence. Mesopleura strongly punc- 
tured under the wings; the upper part of the meta obli- 
quely striated, the strie becoming closer and extending lower 
down on the apex. The abdomen, seen from the back, is 
as in A. spectabilis, cf. Kohl’s fig. Ann. Hof. Mus. Wien. VIII, 
pio MT, £235. 
The ventral segments are as in his figure 36 pl. XII, but 
with the slope not quite so gradual. ‘The hinder tibie are blue 
behind. 
In Kohl’s table thisspecies would come in near A. erythropus. 
Trivogma nigra, Sp. nov. 
Black, shining ; the head and thorax thickly covered with 
long white hair, as are also the coxae, femora and ventral sur-
