7v. latipciiitis Walker. 



My specimens from Teloc Ayer agree both with Wal- 

 ker's short description and his figures. Shoulder keels 

 slightly developed; subantennal processes large, stretching 

 from the apex of the facial keels, of which they appear to be con - 

 tinuations, to back of gena. Rhotaiia I'ifriccps Stal does not ap- 

 pear t(^ he congeneric with lafipcniiis.

The type of this genus, vitriccps, cannot be placed in Rliofaiia, 

 but as I only know it by the description and Melichar's figure I 

 cannot separate it with certainty. The neuration of the tegmina, 

 as shown in ]\Ielichar's figure, differs considerably from R. lati- 

 pciinis \Va\k. 



Dicliofropis gen. no v. 



Type amhoincnsis. 



In profile vertex and face curved, without angulation where 

 they meet ; gena in front of eye about half the width of eye, eye 

 about twice as broad as deep, shallowly cmarginate on lower 

 border ; subantennal process large, the l)ase stretching from facial 

 keels to back of gena ; antennae small, barely reaching to eyes, 

 pyriform, the narrow end a])ical. Vertex small, not reaching to 

 anterior margin of eye, about twice as long as broad, base very 

 slightly broader than apex, acutely angularly emarginate. without 

 keel, sides straight, slightly converging toward apex, keeled, a 

 transverse keel dividing apex from face ; face gradually broad- 

 ening from base to aliout one-fourth from a])cx, where the sides 

 are angular and slightly narrowed to apex, lateral keels deep ; 

 clypeus about as long as face, distinctly tricarinate, lateral carinae 

 contiuuons with lateral facial keels, l^ronotum very short, hind 

 margin angularly emarginate in middle, shoiddcr keels large. 

 Scutellum as long as broad, lateral angles slightK' before middle, 

 tricarinate. I'egmina having wider radial cell than Rlioiaiia, 

 practically the same as Lcini. 



This genus is near to Pccora r)ierm.
