A New Genus of the Orthopterous Subfamily 



Phaneropterinae. 



BY JAMES A. G. REHN. 



ALOGOPTERON* n. gen. 



A member of the Ephippithytse, and related to Polichnodes 

 Giglio-Tos, but differing in the centrally emarginate fastigium, 

 the peculiar venation, the nou-sulcate femora, the heavily 

 spined lower margins of the anterior femora and tibiae and the 

 spinose sterna. 



Fastigium bituberculate ; vertex deplanate. Eyes ovate, 

 strongly exserted. Pronotum elongate, the lateral angk-s 

 rounded ; the anterior margin subsinuate, the posterior strongly 

 rounded ; lateral lobes much longer than high, the lower 

 margins subrotundate. Tegmina very narrow and elongate, 

 the apex anteriorly rounded ; median vein branching from the 

 discoidal vein almost at the very base of the latter, extending 

 unbranched, parallel with and very close to the same for the 

 whole length of the tegmen ; discoidal and humeral vein fus- 

 ing a short distance from the base and apparently not separa- 

 ting again ; anterior ulnar vein extending parallel to the sutu- 

 ral margin for almost the whole length of the tegmen, dividing 

 into forks near the apex of the same ; transverse veins dividing 

 the surface into rectangles, except at the apex where the dis- 

 position becomes more irregular. Wings elongate, much ex- 

 ceeding the tegmina in length, the apex acuminate. Anterior 

 femora and tibiae bearing on their lower lateral margins series 

 of very long and slightly curved spines, anterior and median 

 femora non-sulcate beneath, the respective tibiae being rounded 

 above. Posterior femora slender, non-sulcate beneath and 

 supplied with small spines on the apical portion of lower mar- 

 gins ; spines of the upper margins of the posterior tibiae rather 

 small. Ovipositor short, not equalling the pronotum in length, 

 moderately curved, the apical margins very minutely dentate.
