thorax dull, the abdomen a little more shiny. Pilosity very 
sparse and short, grayish. 
Black. Apical half of the mandibles, inner side of the front 
femora, inner side of all tibiae, tibial spurs, tarsi, center of tegulae, 
and extreme apex of abdomen, more or less ferruginous. The 
following markings are ivory-white: a transverse spot covering 
the upper third of the clypeus; upper two-thirds of the inner 
orbits, including the ocular sinus and extending to opposite the 
posterior ocelli; upper half of the cheeks (broadly separated 
from the white inner orbits); broad anterior margin of the pro- 
notum (a little produced behind on the sides, but not reaching 
the mesopleura) ; a small triangular spot in the hind corner of the 
pronotum, close to the tegula; a median, rectangular spot in the 
posterior third of the mesonotum (between the parapsiclal fur- 
rows); a line on each side of the mesonotum, close to the tegula; 
scutellum (except for the apical, depressed rim and a broad, semi- 
circular, basal spot); entire upper plate of the mesepisternum ; 
dorsal lateral areas of the propodeum, covering the lateral angles 
and extending slightly into the concavity and over the ventral 
areas; tegulae anteriorly, posteriorly and along the inner margin; 
apical margins of the first to fifth abdominal tergites, the fasciae 
deeply emarginate on each side of the middle (on the fourth and 
fifth tergites the median portion is nearly as wide as the sides, 
but it is considerably narrower than the sides on the second and 
third, while the first is but narrowly margined with white in the 
middle and has the sides abruptly and very extensively white); 
a small spot in the hind angles of the third to fifth sternites; an 
elongate, narrow spot on the anterior (outer) face of the middle 
and hind coxae; outer apices of all the femora; a stripe on the 
outer face in the basal half of the front tibiae; and outer face of 
middle and hind tibiae. The under side of the sixth to tenth an- 
tennal segments is more or less spotted with ferruginous to dirty 
white. Wings subhyaline, fairly uniformly tinged with amber- 
yellow, a little more smoky in the radial cell; veins ferruginous, 
the costa paler; stigma amber-yellow. 
Male unknown.
