Front of head between frontal carinae longitudinally striate; remainder of front except between eyes and antennae, strongly and concentrically striate; lateral fossae at the anterior border with short striae, but most of the surface smooth and shining; vertex and sides densely striate, the striae becoming more subtle posteriorly and lacking for a short distance from the sides of the medial impres- sion; occiput sparsely punctate and shining. Prothorax transversely and somewhat arcuately striate; meso- and epinotum transversely striate. Base of petiolar node striate. Gaster finely punctate and shining. Female. Length 19 mm. Mesonotum and scutellum with strong longitudinal striae. Anterior portion of prothorax, a discal spot, disc of mesothorax and anterior face of scutellum fuscous. The rest as in worker, with the usual sexual differences. Wing (length 12 mm.) faintly infuscated; veins and stigma brown. Male. Length 12 mm. Head, excluding eyes, longer than broad, broadly rounded behind. Mandi- bles rudimentary. Cl3rpeus convex, the anterior border almost straight. Antennal scape thick, three times as long as the first funicular joint; funicular joints, except the first, very long and slender; the second three times as long as the scape; remaining joints gradually shorter; with the terminal joint less than twice as long as the penultimate. Eyes emarginate on inner border. Ocelli large and prominent. Me- sonotum little convex above. Scu- tellum a little broader than long, somewhat pyramidal in shape, with a short, longitudinal impres- sion at apex. Epinotum slightly convex basally, with a well-marked declivous portion. Petiole two and a half times as long as broad; in profile twice as long as high; anterior face concave, narrowly margined at sides; upper surface elevated into a flat
