 short black pubescence, which is longer and thicker on the face

 above it bears t\^o oblique fovefe, the space between them being 

 depressed ; in the centre below is a smaller oval one. The sutures 

 on the vertex are wide and deep ; in the middle behind is a short 

 deep furrow ; bordering the inner side of the antennae is a smooth 

 curved furrow. Apex of the clypeus closely punctured. Mandibles 

 at the base closely rugose ; the apex broadly rufous. Thorax and 

 abdomen smooth and shining ; the mesonotum thickly covered 

 with short black hair. Cenchri large, white. Wings fuscous- 

 violaceous ; the nervures and stigma black ; the 2nd cubital

 nigris. $ . 



Long. 24 mm. 



Antennae black, slender. Front rugosely punctured above ; the 

 sides above stoutly obliquely, the lower part transversely striated, 

 the ocellar region irregularly reticulated, the keels below them 

 mostly curved ; above the reticulated upper portion are four long 

 curved keels, the vertex behind these is irregularly rugosely 

 striated ; the ocellar I'egion is distinctly depressed : the three 

 tubercles form a triangle. The base of the pronotum is smooth 

 and shining ; behind on the sides are two stout curved keels ; the 

 rest of the pronotum is opaque and irregularly transversely striated. 

 The base of the mesonotum is smooth and shining ; the rest of it 

 bears mostly large and deep punctures, except on a space on either 

 side of the centre ; on the sides and base the punctures tend 

 to become confluent. Scutellum somewhat triangular in shape, 

 smooth, shining, and impunctate. Median segment closely, 

 stoutly, irregularly punctured ; behind the punctures run into 

 reticulations. Propleurae smooth and shining ; the meso- opaque, 

 irregularly punctured, and striated ; the meta- rugosely punctured.
