Bruner: Soi in American Acridoidea. 117 



produced between the antennae, aboul .is broad as the basal joint, nol 

 sulcate, I'm coarselj punctate ab< ve the ocellus, somewhal narrowed 

 and much weaker below anil continued to the clypeus, -nl' .lie; lateral 

 or facial carina subparallel, the face rugose between them. Antennas 

 twenty-jointed, rather long, heavy, and ensiform, or subensiform. 

 Pronotum coarsely rugoso-punctate, without lateral carinas, evenh 

 divergent posteriorly, the dorsum rounded, and with a well-defined 

 median carina: hind lobe shorter than the front, separated by a 

 ptrongh defined transverse sulcus; anterior margin straight, posterior 

 margin broadly obtusangulate. Tegmina long and narrow, rather 

 closeh veined on basal, more distantly on distal, half. Wings blue, 

 infuscated apically, long, and narrow. Abdomen rather short, taper- 

 strongly carinated above; valves of the ovipositor acuminate.. 

 the outer edge of the upper pair crenulate. Hind femora extending 

 beyond the tip of the abdomen, more than ordinarily robust, and with 

 the upper carina serrate; hind tarsi with the second joint much shorter 

 i han the first. Space between the mesosternal lobes subquadrate, 

 wider than long. Prosternal spine slender, straight. Hind tibiae 

 with seven spines in outer row, the apical spine wanting. 



164. Rhabdoscirtus vittatus sp. nov. 

 The type of this genus is vittatus. It is of medium size, has the 

 general color black, varied with rlavo-testaceotis vittae as follows: one 

 extending from the base of the antennae down each side of the face 

 to the base of mandibles, one from the back of each eye diagonally 

 across the cheeks and lower portion of sides of pronotum and pleura 

 io base of middle legs, one on each side of occiput and disk of pro- 

 notum and along dorsal angle of folded tegmina for two-thirds their 

 length. The tegmina are also provided with a second and shorter 

 line of this color just back of their costal edge. There is another on 

 each side, which runs from the base of the tegmina to the insertion of 

 the hind femora. These latter have a conspicuous stripe along the 

 lower edge of their outer face, and a second one extending from near 

 the middle of the base diagonally upward and to the rear, where it 

 crosses to the inner face about one-third the distance towards the 

 apex. A second short diagonal band of this color crosses the upper 

 edge just beyond the middle. The palpi are pale, their apical joints 

 being terete. The anterior edges of the three segments of the thoracic 

 sternites are also pale. The wings are rather dark transparent blue 

 with dusky apices.
