band originating at the middle of the stigma ; nervUres 

 obscure testaceous, paler at the base ; the stigma fuscous,, 

 pale at the base. Head finely rugosely punctured, semi- 

 opaque. Eyes slightly diverging beneath. Ocelli hardly 

 forming a triangle, the anterior being too far in fronts 

 separated by a greater distance from the posterior than 

 these are from each other. The posterior separated from 

 each other by half the distance they are from the eyes. 

 Clypeus convex, keeled in the middle, the apex triangular. 

 Apex of mandibles piceous. Prothorax finely and closely 

 punctured, somewhat convex above, the sides concave, 

 furrowed in the centre, the lower part of the concavity 

 projecting more than the upper, the edge of the latter being 

 furrowed and margined ; prosternum furrowed, widely in 

 front, narrowing behind. Mesothorax finely punctured ; 

 parapsidal furrows wide, parallel ; there is a large shining 

 keeled depression below the tubercles, the pleurae behind 

 this being convex ; mesopleurae widely furrowed, keeled 

 in the centre. Median segment with a straight central and 

 two lateral curved converging keels in the centre ; and, on 

 the edge, are two other keels ; the interstices transversely 

 striolate ; the apex semiperpendicular, transversely striolate 

 and keeled above. 



Rhinopsis ruJicorniSyCdiXnAS nearly related toR. ConstancecB^ 

 but differs in having the hinder ocelli separated from the 

 eyes by more than twice the distance they are from each 

 other ; in the mesonotum being without black at the base, 

 in the scutellum being ferruginous ; in the pronotum being 

 deeply furrowed in the middle, in the apex of the median 

 segment being tuberculate laterally before the curve ; in 

 the lateral central keels being less distinct and more widely 

 apart ; in the narrow part of the petiole being longer, the 

 apex nodose ; vi^hile in Constancece it becomes gradually 

 developed from the middle ; the legs are stouter^nd have the 

 femora not so attenuate at the apex ; the wings are shorter
