 thickly with minute, stiff pubescence. Head black ; the 

 inner orbits from the antennae to the base of the mandibles 

 broadly, the upper third narrowly, yellowish testaceous. 

 Face strongly punctured, running into irregular reticula- 

 tions ; projecting in the middle below the antennae ; the 

 apex of the clypeus impunctate, the sides straight, oblique. 

 The basal half of the mandibles above and below with 

 large, deep punctures ; the middle with two stout keels ; 

 covered with longish, white hair ; the palpi fuscous. Meso-

 base transverse, the middle lobe forming a large triangular 

 piece raised above the rest, especially at the base. Scutel-

 punctures large, deep, more widely separated ; the fovea 

 at the base large, deep, as wide as the base of the 

 scutellum ; in the middle are three stout keels ; the middle 

 one straight, the outer slightly thinner and more oblique. 

 Postscutellum flat, large, having a small fovea in the 

 centre at the base, and a large deep one, on either side, 

 reaching near to the apex. Median segment at the base 

 with a small area wider than long and with its apex 

 roundly bent inwardly in the middle ; the apex flat ; 

 stoutly transversely striolated ; the sides at the base 

 irregularly reticulated, irregularly margined at the apex ; 

 the sides irregularly reticulated in front of the spiracles. 

 The base and apex of the propleurae closely punctured ; 

 the middle depressed ; the central depression at the top 

 somewhat obliquely, the rest stoutly longitudinally, strio-
