quite half as long as the tibia, equaling in length the distance 
from the base of the fourth joint to the apex of the fifth; 
fourth joint much longer than the second and third united, 
widened distad; median claw of chela as long as joints 1 to 4 
united, with a row of short white plates below; lateral claw 
yellow, bare, curved behind the middle, narrow, as long as joints 
1 and 2 united, with a short tooth before the apex; legs entirely 
covered with a short white pubescence; tarsal claws sharp, with- 
out teeth; wings as in P. thoracicus, but with a narrow trans- 
verse band in the region of the radius and with the radius a 
little shorter; it can be clearly seen that the darker color 
of the wings is due to the presence of pigment in the hairs; 
abdomen rather long, sharply pointed and narrowed toward 
apex, polished, sparsely covered with short white hairs; first 
segment bell-shaped, of the form found in the wasps of the 
subgenus Odynerus; sixth segment shorter than the fifth, longer 
below than above; ovipositor projecting the length of the last 
tergite. Body black; antenne at tip and abdomen at base and 
apex touched with rufous. 
Luzon, Los Bajios (Baker), 2 females. 
Type.—Catalogue No. 24326, United States National Museum. 
One specimen has the ovipositor more in evidence. The ab- 
dominal segments are telescopic and so the relative proportions 
vary considerably. |
