2. Schistocerca aurantia sp. nov. 



Of moderate size and stoutness, fusco-testaceous somewhat obscured 

 with fuscous. Head rather large, nearly uniform fusco-testaceous, above 

 with feeble, more or less divergent, dull fuscous stripes ; frontal costa 

 subequal, not very broad, j^unctate, deeply sulcate below the ocellus ; 

 eyes narrow elliptical, very much longer than the infraocular portion of 

 the genje ; antennoe testaceous, the distal half infuscated. Pronotum well 

 arched but not tectate, expanding slightly on the metazona so as to be 

 about as broad as at the eyes, with a feeble median carina, merely indi- 

 cated on the prozona, the latter produced anteriorly and rounded, a little 

 shorter than the metazona, scabro-punctate, a little more coarsely than the 

 metazona, the whole pronotum uniform in color except that the metazona 

 is more or less ferruginous, posteriorly rectangulate. Prosternal spine 

 moderate, erect, cylindrical or feebly tapering, blunt. Tegmina consid- 

 erably longer than the body, moderately slender, testaceous becoming 

 subvitreous distally, maculate with moderately large quadrate or rounded 

 fuscous spots, darker proximally than distally and pretty uniformly dis- 

 tributed in the median area, the costal and anal areas more or less minutely 

 flecked with fuscous; wings hone3^-infumate, the veins flavous and the 

 cross-veins fusco-flavous, with a slight sprinkling of fuscous dots apically. 

 Fore and middle femora not inflated in the male ; hind femora scarcely 

 surpassing the abdomen, fusco-ferruginous, the outer face whitish, the 

 carinai with the serrations marked with fuscous ; hind tibia3 fusco-ferru- 

 ginous verging on puri)lish, the spines luteous, apically black. Male 

 cerci nearly twice as long as basal breadth, tapering only a little, apically 

 truncate and broadly emarginate ; subgenital plate narrowly and rather 

 deeply fissate apically.

 decolored.
