Posterior tibiae black at apex. J . — 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 tegulze, a large spot on the col- 

 lar, a spot above the anterior coxm, a broad stripe on the pleurae, a spot above 

 the posterior coxa;, the front and middle cox^-e except above, the apices of the 

 posterior coxa?, the trochanters, the front legs beyond the coxa; (the tibiae and 

 the tarsi are greenish), the middle femora (one specimen has a small black 

 spot on the apex above), the middle tibi;T; except a black spot at apex 

 above, the basal segment of the middle tarsi beneath, the basal half of the 

 posterior femora, the posterior \\h\x except at apex, the scutellum, a Ime on 

 the postscutellum, the basal plates, the venter 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 antennre twice the length of the fourth; the wings 

 hyaline, slightly infuscated towards the apex ; the veins and the costa black ;
