"Abridged in shape like some of the DeltocepJialince, but with 

 the vertex straight, not produced in front; face strongly tricarinate, 

 the lateral carinations prolonged on the upper side of the head ; 

 antennse twice as long as the head and pronotum united as 

 in Delphax, with the second joint three times longer thaji the 

 first ; eyes oblong, prominent, sinuate beneath : pronotum 

 straighter than the head, produced forwardly to nearly half 

 the length of head ; mesonotum joined to the pronotum and 

 indistinct ; tegmina cartilaginous, not o'* only a little hyaline, 

 oval, attenuated or truncated behind and not extending beyond 

 the apex of the abdomen ; veins prominent, sometimes articulate, 

 and all longitudinal almost to extremity, the direction of the 

 subradial and posterior veins here a little approaches the median 

 vein, giving to each a veinlet which reaches the extremity of the 

 tegmen, whilst they are reunited to the median vein by two small 

 transverse veins, after which there are only two parallel veins 

 which reach the extremity ; legs long and rough, posterior tibiae 

 very long and armed with three spines ; tarsi robust, their first 

 joint longer than the others together." {Motscliouhhy.) 



I have not seen this genus, but the shortened tegmina will 

 alone distinguish it.
