another fine carina runs straight backward to the edge of the declivous 
portion of the propodeum, where it branches, the inner branch connecting 
with the submedian carina, the outer branch extending towards the pos- 
terior lateral corner of the propodeum, still another branch is given off 
anteriorly and runs forward to the spiracle; spiracles rather large, oval 
and contiguous to the basal margin of the propodeum. 
Reticulation of head and thorax very fine and delicate, but somewhat 
coarser and more evident on the face; frontovertex with two longitudinal 
rows of pin-punctures on either side of the median line, and an orbital 
row of much finer punctures on each side; mesonotum with numerous seri- 
ately arranged, minute setigerous punctures similar to the orbital punctures 
of the head, and becoming sparser on the axillae and secutellum; prepectal 
plates as coarsely reticulate as the face; mesopleura with an extremely 
fine reticulate shagreening; propodeum except for the carinae described 
above is mostly smooth; reticulation of the abdomen rather coarser and 
more evident than that of the face and with the lines mostly transverse, 
especially on the basal tergite. 
Eyes with an extremely short sparse pubescence, not apparent except 
under high magnification; pubescence of head and body short, recumbent 
and dark-colored, antrorse on the frontovertex and retrorse as usual on the 
thorax, that of the axillae and seutellum becoming sparser and the apex 
of the seutellum with two considerably longer setae; sides of the pro- 
podeum behind the spiracles with a very fine whitish pubescence, which, 
however, is not conspicuous; pubescence along the sides and at the apex 
of abdomen sparse, but somewhat longer than that of the thorax. 
General color moderately lustrous black; head with a rather weak 
bluish-green luster, the face more lustrous and greenish; mesoseutum usually 
somewhat bluish, but sometimes like the axillae and scutellum, which are 
darker and more aeneous; lateral posterior corners of the propodeum with 
a rather bright bluish luster; abdomen mostly like the seutellum, but the 
apical tergite has a brighter and greenish luster; antennae and legs con- 
eolorous with the body, but less lustrous, the tarsi mostly yellowish, with 
the last three joints of the hind pair, the last joint and the spines on the 
plantar surface of the middle pair fuscous, the front pair more or less 
dusky yellow, the spur of the middle tibiae yellow; wings hyaline, the 
disk with a very faint indefinite fuscous cloud beneath the stigmal vein, 
the veins brownish. 
Length of body (1.16 to) 1.32; length of head, 0.497; width of head, 
0.601; thickness of head fronto-occipitally, 0.325; width of vertex at an- 
terior ocellus, 0.085; length of antenna, 0.662; width of mesoseutum, 0.561; 
length of fore-wing, 1.027; width of fore-wing, 0.502 mm. 
Male. Very much like the female in most respects and the following 
differences appear to be the most important: Vertex widening a little 
more at and behind the posterior ocelli, somewhat protuberant and rather 
more dully shagreened; ocelli slightly larger and in a less acute triangle;
