TWO NEW WASPS OF THE GENUS AMPULEX. 
segments moderately compressed laterally. Radial cell 
pointed *at the apex; only two cubital cells, the third 
abscissa of the radius half as long as the second, so that 
the second transverse cubital nervure is received at a con¬ 
siderable distance from the apex of the radial cell. The 
penultimate joint of the tarsi is more than half as long as 
the apical joint, which is inserted at the base of the 
penultimate. 
Hab .—Limbang River, Sarawak. April, 1910. (J. G. 
Moulton.) 
This does not seem to be very near to any described 
species, though resembling A. trichiosoma, Gam., in the 
long black hairs on the head and thorax, but the head in 
that species is narrowed into a neck behind the eyes. 
Ampulex moultoni , sp. n. 
Viridi-caerulea, nitida; antennis, clypeo, mandibulis 
tarsisque nigris; tibiis anticis piceis ; femoribus posticis 
et intermediis rufis; alis hyalinis, leviter infumatis, vena 
prima transverso-cubitali obliterata. 
Long. 18 mm. 
2 .—Antennae short and stout, the second joint of the 
flagellum longer than the third by about one quarter. 
Clypeus strongly raised in the middle, the longitudinal 
carina from the base branching before the middle, the 
branches produced to the apex of the clypeus and enclosing 
an elongate triangular area. Head rather deeply punctured, 
rather closely on the front, very sparsely on the vertex. 
Eyes converging strongly towards the vertex, where they 
are separated by a distance about equal to the length of 
the second and third joints of the flagellum. Head slightly 
produced behind the eyes. Pronotum a little broader in 
the middle than long, very deeply punctured, with a longi¬ 
tudinal sulcus reaching from the anterior margin to the 
middle. Mesonotum and scutellum very sparsely punc¬ 
tured ; the mesopleurse rather more closely punctured and 
without a longitudinal groove. Median segment a little 
broader in the middle than long, the tooth at the posterior 
angles rather short and blunt, but better defined than in 
atrohirta ; the third longitudinal carina is nearly twice as 
far in the middle from the second as from the fourth. 
Abdomen shining, with a few minute punctures, somewhat 
compressed laterally in all the segments, very strongly in 
the apical segments ; the second dorsal segment nearly 
twice as long as the median breadth. Penultimate joint
