cj. Clypeus pointed and prominent at the base and comiected 

 by a short carina with the interantennal prominence, very broadly 

 truncate at the apex, the apical angles not prominent, strongly 

 longitudinally striated. Interantennal prominence very broadly 

 triangular, a low longitudinal carina from the apex reaching more 

 than half-way to the anterior ocellus. Front rugosely punctured, 

 irregularly rugose striate above the base of the antennae; vertex 

 more sparsely punctured. Antennae about as long as the thorax 

 and median segment combined ; pronotum rather sparsely and finely 

 punctured, with a shallow shining groove behind the slightly raised 

 anterior margin; mesonotum very closely punctured between the 

 deep parapsidal furrows, but much more sparsely in the middle. 

 Scutellum very broadly rounded at the apex, subtruncate, rather 

 closely punctured ; median segment oblique from the postscutellum, 

 finely rugulose, the middle rather sparsely punctured. Abdomen 

 somewhat elongate, the basal dorsal segment oblique anteriorly, 

 as broad at the apex as the second segment, all the segments rathea" 

 sparsely punctured and not constricted; sixth ventral segment 

 with a spine on each side at the apical angles; seventh dorsal 

 segment produced into a broad flattened lamella, longitudinally 

 striated and very broadly rounded at the apex. Hypopygium 

 obliquely striated above, subtriangular, broad at the base with a
