B B. Pronotum above plane, more gently cristate, the severing not oblique; aiite- 

 rior edge very ol)tusely angulate, behind subacute. Wings bright car-

Upper carina of hind femora not suddenly narrowed orizabw Saussure. 



A A. Tegmina with their apices rounded. Head and pronotum less strongly gran- 

 ulate; scutellum of the vertex more strongly declivent, smoother. Eyes 

 larger. Pronotum carinate, but in nowise cristate; the anterior border sub- 

 truncate. Wings yellow, the fuscous band not reaching the anal angle. 

 Spurs of hind tibia' not greatly unequal azfecus Saussure. 



The above-described new species is very like a red winged Arj>h!((^ 

 so much so indeed that it is very Iial)le to be taken as such. The 

 sternal characters serve, however, to separate it from the members of 

 that genus. 



MESTOBREGMA GRACILIPES, new species. 



Two males, Nogales, June 3u, fluly 21. Two females. Huachuca 

 Mountains, August 25 and 27.
