8. Schistocerca mellea sp. nor. 



Of medium size and moderately stout, fusco-testaccous with a ferrugi- 

 nous tinge. Head ferrugineo-testaceous, with the margins of the frontal 

 costa and facial caringe punctate with fuscous, a pair of diverging fuscous 

 stripes on the vertex and a genal stripe below the eyes ; frontal costa 

 slightly narrowed just below the ocellus and feebly sulcate, excepting 

 above ; eyes a little tumid in the male, much longer than the infraocular 

 portion of the geuse ; antennae ferrugineo-testaceous. Pronotum well 

 arched transversely, in no way tectate, the median carina faint excepting 

 on the metazona of the female, where it is slight ; prozona obscurely 

 ruguloso-punctate, slightly and scarcely angularly produced anteriorly, a 

 very little shorter than the rather finely punctate metazona, which enlarges 

 considerably jiosteriorly, so as to be considerably broader than at the eyes, 

 and is posteriorly rectaugulate, or in the female faintly obtusangulate; 

 the whole pronotum is ferrugineo-testaceous, the disk, at least in the 

 female, strigate and blotched with fuscous, leaving clear a broad median 

 stripe, the lobes irregularly maculate with fuscous, the middle with a 

 longitudinal fuscous bar, all of which is very obscure in the male. Pro- 

 sternal spine erect, moderately slender, conico-cylindrical, blunt. Teg- 

 mina extending considerably beyond the abdomen, not very slender, 

 ferrugineo-testaceous, profusely and distinctly maculate throughout with 

 fuscous, in the distal half arranged rather conspicuously in transversely 

 oblique stripes ; wings honey yellow with a smoky tinge, apically macu- 

 late in the upper area. Fore and middle femora not enlarged in the male; 

 hind femora about reaching the tip of the abdomen, ferrugineo-testaceous 

 with hoary outer face, which is punctate with black, as are also the serra- 

 tions of the carinas ; hind tibite ferrugineo-testaceous, the spines pallid 

 with black tips. Male cerci moderately slender, feebly tapering, about 

 twice as long as basal breadth, apically truncate and feebly and broadly 

 emarginate ; subgenital plate rather elongate, scaphiform, apically fissate 

 narrowly half way to the base, the flaps so formed acutangulate, the angles 

 rounded.
