Moderately flat, subovate ; head about as broad between 

 the eyes as long, lobes of equal length, but the apices of the 

 lateral lobes a little obliquely directed to the central, which 

 makes the latter appear slightly prominent; ocelli near base, 

 much nearer to eyes than to each other ; antennae five- 

 jointed, basal joint robust, slightly passing apex of head, 

 second joint slightly longest, third short, about equal to 

 first, fourth and fifth subequal, each a little shorter than 

 second ; pronotum about half as long as broad at base, 

 lateral margins roundly oblique, very slightly sinuate, lateral 

 angles rounded, not prominent, anterior margin coiicavely 

 sinuate, anterior angles slightly angularly prominent, basal 

 margin almost truncate; scutellum longer than broad, 

 obliquely narrowed to apex, which is subangulate, a little 

 longer than pronotum ; corium about as long as scutellum 

 and pronotum together, the apical margin straightly oblique ; 

 membrane scarcely passing the abdominal apex, veins longi-
