Posterior tibiae black at apex. 9 .—Black, with the following parts yellowish- 
white : the labrum, the clypeus, the mandibles except at apex, the cheeks, 
a spot above the base of each antenna, the tegulm, a large spot on the col¬ 
lar, a spot above the anterior coxae, a broad stripe on the pleurae, a spot above 
the posterior coxae, the front and middle coxae except above, the apices of the 
posterior coxae, the trochanters, the front legs beyond the coxae (the tibiae and 
the tarsi are greenish), the middle femora (one specimen has a small black 
spot on the apex above), the middle tibiae except a black spot at apex 
above, the basal segment of the middle tarsi beneath, the basal half of the 
posterior femora, the posterior tibiae except at apex, the scutellum, a line on 
the postscutellum, the basal plates, the vehter except the apical segment and 
the sheaths of the ovipositor, and the sides of the segments of the tergum 
(their inner caudal angles dilated along the caudal margin of the segments, 
coalescing at middle) except on the filth segment (the black on the middle 
of the tergal segments is in the shape of a wide equilateral triangle, in one 
specimen the fourth segment is entirely pale) ; the clypeus emarginate; the 
third segment of the antennae twice the length of the fourth; the wings 
hyaline, slightly infuscated towards the apex; the veins and the costa black;
