apices of the coxae, the trochanters, femora, tibiae, and tarsi orange 

 red, a broad transverse yellow band on the posterior margin of the 

 pronotum spreading on to the anterior margin of the mesonotum 

 in the middle, an elongate stain on the posterior tibiae and the 

 anterior and intermediate tarsi also more or less washed with pale 

 yellow, apical segment of abdomen above white ; wings hyaline 

 forewing fuscous at apex, veins testaceous. Head as broad as the 

 thorax convex in front remarkably flat posteriorly, in appearance 

 like the half of a pea ; mandibles bidentate at apex, labrum tri- 

 angular, clypeus anteriorly arched, raised in the middle by a strong 

 transverse carina, that has a sharp vertical carina impinging on 

 it in the middle, the latter carina is continued upwards between 

 the base of the antennae to the forehead ; ocelli in a triangle on 

 the vertex, antennae comparatively short, robust, moniliform, ^yee, 

 large, their inner margins parallel. Thorax very long, a third as 

 long again as the abdomen ; pronotum rounded anteriorly and at 

 the shoulder, its posterior margin arched ; mesonotum very slightly 

 convex, scutellum elongate triangular and laterally strongly com- 

 pressed, median segment evenly rounded posteriorly and obliquely 

 sloped, a broad very ill-detined longitudinal furrow to apex ; wings ; 

 forewing the radial cell large pointed at apex, the medial and 

 submedial cells of the same length, the basal and 1st transverse 

 subbasal nervures therefore interstitial, 1st cubital cell about as 

 long as the 2nd and 3rd united, 2nd cubital cell quadrate receiving 

 the 1st recurrent nervure about three-fourths of its length from 

 base, 3rd cubital cell trapezoidal, measured along the cubital 

 nervure below it is about twice the width it is at top ; hindvving 

 the cubital nervure originates before the apex of the submedial 

 or anal cell, the cubital nervure at origin therefore not interstitial 

 with the transverse anal nervure. Legs short, stout, cylindrical, 

 spines large and stout, intermediate inner tibial calcar four-fifths, 

 posterior inner tibial calcar three-fourths as long as their respective 

 metatarsi, claws of fore tarsi bitid, of intermediate and. posterior 

 tarsi toothed beneath. Abdomen short and stout. Head, thorax 

 and abdomen dull and opaque covered somewhat sparsely with 

 short erect pale hairs, these are white and silvery at the apex of 

 the median segment and are there longer and denser.
