Bruner: Saltatorial Orthoptera. 69 



120. Zosperamerus vittatus sp. nov. 



The smallest representative of the genus so far as known, and easily 

 separated from the other species by the entire absence of pallid macu- 

 lations. Head, pronotum, meso- and metathorax, and tegmina bruneo- 

 ferruginous, quadrivittate with black. 



Head about as broad as the anterior margin of the pronotum; the 

 front somewhat oblique, the occiput rounded; vertex between the 

 large prominent eyes very narrow, its width no more, or scarcely as 

 great, as the diameter of the slender antennae; fastigium of the vertex 

 depressed, rather small, about as long as wide, gently sulcate, and 

 separated from the frontal costa by an arcuate, blunt, transverse 

 ridge; the costa somewhat produced above the antenna?, plane, its 

 greatest width a little more than twice that of the vertex, gradually 

 narrowing below, sulcate just above the ocellus and below, almost 

 terminating in the middle of the front at the rather large transverse 

 callosities of the face. The latter coarsely rugose-punctulate; the 

 lateral facial carinae coarse, gently bowed outward at their middle and 

 reaching the clypeus. Antenna? slender, about one-fourth longer than 

 the head and the pronotum combined, the basal joint rather large. 

 Pronotum punctulate, a little longer than wide, expanding posteriorly, 

 the anterior margin sinuate, the posterior one widely rounded; median 

 carina of equal prominence throughout, thrice severed by the trans- 

 verse sulci, the last about one-third the length of the pronotum from 

 its hing margin; the lateral carinae wanting. Tegmina gently taper- 

 ing, the apex rounded and reaching the hind edge of the eighth ab- 

 dominal segment; wings reaching the tips of the tegmina, strongly 

 infuscated at least apically, the disc and base not visible in the only 

 specimen before me. Hind femora robust, about reaching the tip of 

 the abdomen. Valves of the ovipositor, especially the upper pair, 

 heavy, and coarsely toothed, the apex a little curved upwards, lower 

 pair smaller, weaker, and much shorter; the supra-anal plate moder- 

 ately large, its general form triangular, greatly arched at middle, and 

 provided with an apical prolongation or finger, which is longitudinally 

 sulcate. Mesosternal lobes widely separated, the prosternal spine 

 acuminate. Hind tibia? and tarsi hirsute, the former with five spines 

 on the outer edge, seven internally; the hind tarsi with the first joint 

 much longer than the second and about equal to the third. 



Length of body, 9, 20 mm.; of pronotum, 4 mm.; of tegmina, 

 II mm.; of hind femora, 10.5 mm.
