Length S mm. 



A médium sized species, moderately elongated. The pubescence dense, fuscous. Third 

 antennal joint about one third longer than the 4* , clearly shorter than the following two 

 joints united. Head slightly wider than the base of the pronotum; the front and vertex deeply, 

 strongly punctured, the latter more strongly than the former. Apical half of the pronotum 

 wider than the basai, rounded. Upper part of thorax strongly, closely punctured, the punc- 

 tures round and deep. Post-scutellum roundly convex, not raised above the scutellum, the 

 apex roundly narrowed ; it is bordered behind laterally by a longish fovea with a few stout 

 keels in the centre; between the two latéral foveae is a shorter deeper one with 2 stout 

 keels in the centre. The upper latéral angles of the metanotum project into a stout tooth, 

 longer than its width at the base and narrowed towards the apex. Upper part of propleurae 

 depressed, above strongly, irregularly punctured; the middle less strongly punctured and with 

 a longish fovea at the apex, the lower part finely, closely, irregularly striated-reticulated, 

 smooth behind. Mesopleurae above stoutly punctured, the punctures large, round and deep: 

 the lower part irregularly reticulated. Metapleurae closely, strongly obliquely striated ; the 

 apex deeply depressed, with 2 round foveae below. Back of abdomen closely. uniformly 

 punctured; the 2 nd segment distinctly, the yà- indistinctly keeled down the centre. Ante- 

 apical foveae 10; the inner more distinct than the outer; the}' are not very deep, somewhat 

 oval and violaceous ; the outer teeth are shorter and broader than the central, which is broad 

 at the base, becoming narrowed to a sharp point at the apex.
