Scutelluni convex, its top broadly rounded. Media?i segment 

 .sliarply and w'uU'ly depressed at tlie base, not areolated except 

 in the middle, wiiieh is bordered by two stout keels ; tlieaj)ex 

 has a sharply ubli([uc slope ; on the top at the sides is a stout 

 tooth. Abdomen bluntly pointed at the apex; there are 

 eiu,ht segments in both sexes, the last is small; the ventral 

 fold is stout and extends to the apex of the fourth segment in 

 both sexes. Legs stout, the tarsi bare. 



The abtlominal segments are closely but not strongly punc- 

 tured, and do not angularly project at the a|)ex laterally ; the 

 sides of the median segments are bordered by stout keels ; 

 the head is obliquely narrowed beliind the eyes; the lower 

 sides of the pleurie are not broadly rounded ; the part of the 

 meso[)leura^ above the middle broadly and roundly projects, 

 the part immediately under the wings being depressed ; 

 below the raised part of the scutellum is a stout keel, 

 which also extends round the apex, but is narrower there 

 than on the sides; its apex has a rather steep slope; the 

 hunt is deeply and widely depressed ; the clypcus is more 

 distinctly convex than usual. The abdomen is not much 

 longer than the thorax. 



lias the coloration of Gathetus, Facydts, and Dimmtha. 

 The first-named is readily known from it by the flat scutellum, 

 by the much shorter, more distinctly dilated antennas, and by 

 the striated abdomen. Facydes and Dimcetha have also the 

 antennaj shorter and more distinctly dilated, and have the 

 sides of the abdominal segments angularly projecting, and 

 both have the clypeus flat, while lh'm(et/ia has also the 

 abdomen much longer, the postpetiole nnich narrower, the 

 legs longer, and the scutellum not pyramidal.
