The type is unique. The species superticially bears considerable 

 resemblance to species of the genus ScJilstoverca, a fact noted by 

 (liglio-Tos in his description of the closel}' allied S. horellii. 



STIRAPLEURA Scudder. 

 STIRAPLEURA BRUNNEA, new species. 



Types. — Male and female; Chapada, Matto Gr rosso, Brazil. August

Allied to iS'. pallida and ohneura Bruner, but differing from the 

 former in the larger head, broader fastigium, constricted pronotum, 

 and more uniform coloration. From S. ohscura it differs in the larger 

 size, shallower and narrower fastigium, and shorter but more inflated 

 caudal femora. 



Size medium; form moderatel}" robust. Head with the fastigium 

 broad, slightly acute-angulateinthe male, obtuse-angulatein the female, 

 rounded, depressed area crescentic in the female, semicircular in the 

 male; interspace between the eyes ver}' little narrower than the greatest 

 width of the fastigium and but slightl}" more than half again as wide 

 as the dorsal portion of the frontal costa; lateral foveolte slightl}^ longer 

 than wide, impresso-punctate; angle of the fastigium and frontal costa 

 when viewed laterad very slightly rounded; face distinctl}^ retreating, 

 slightly arcuate; frontal costa tumid, slightly but gradually expanding 

 ventrad, not sulcate, irregidarly punctate; supplementary facial carina} 

 distinct, strongly divergent; eyes ovoid, distinctly (male) or slightly 

 (female) longer than the infra-ocular portion of the gente; antennae 

 slightly depressed proximad. Pronotum with the cephalic margin 

 slightly arcuate, caudal margin obtuse-angulate, tlie angle very nar- 

 rowly rounded; median carina distinct, cut in the middle; lateral carinje 

 distinct ce{)iialad and caudad. ()l)sol(>te mesad, moderately constricted; 

 latcrid lol)es about half again as deep as long, cephalic and caudal 

 margins parallel, ventral margin rounded, i-otundato-emarginate ceph- 

 alad. Tegmina extending beyond the tips of the caudal femora by a 

 distance slightly less than the length of the pronotum; veins coarse; 

 tips rotnndate; costal dilation .slight; postradial area irregularly areo- 

 late with a crude biareolate arrangement distad. Caudal femora con-
