(Plate XV, fig. 10.) 

 Pezotettix scudderi WALSH ! , MS. 



Kather above the medium size, ciuereo- fuscous. Head not promi- 

 nent, dull testaceous, more or less infuscated, especially above, with a 

 distinct or obsolete piceous postocular band; vertex gently tumid, 

 feebly elevated above the pronotum, the interspace between the eyes 

 almost (male) or much more than (female) twice as broad as the first 

 anteimal joint; fastigiuin steeply declivent, broadly and moderately 

 (male) or very shallowly (female) sulcate; frontal costa hardly reaching 

 the clypeus, equal, a little (male) or distinctly (female) narrower than 

 the interspace between the eyes, faintly and broadly sulcate at and 

 below the ocellus, punctate throughout, but above particularly in lat- 

 eral series; eyes not very large, moderately prominent, particularly in 

 the male, the front margin truncate in the female, a little (female) or 

 distinctly (male) longer than the intraocular portion of the genae; 

 antennae testaceous, basally lutescent, apically fuscescent, slightly 

 more than two-thirds as long as the hind femora in the female. Pro- 

 notum equal except for a feeble posterior enlargement of the inetazona, 

 the sides with a very broad piceous postocular band crossing the pro- 

 zona and, obscurely, also the metazona (male) or with scarcely the 

 slightest trace of the same, but at most a growing depth of tint at the 

 upper limit of the lateral lobes (female), the disk plano-convex, passing 

 into the subvertical lateral lobes by a well but abruptly rounded angu- 

 latiou, forming dull lateral carinae; median carina distinct but low on the 

 metazona, obsolete on the prozona. except sometimes a slight appear- 

 ance at extreme front; front margin truncate, hind margin strongly 

 obtusangulate; prozona distinctly longitudinal (male) or quadrate or 

 subquadrate (female), much longer than, generally half or nearly half 

 as long again as, the ruguloso-punctate metazona. Prosterual spine 

 moderately long and stout, especially in the female, appressed conical, 

 not very blunt, erect; interspace between mesosternal lobes truncato- 

 cuneiform, quadrate (male) or distinctly transverse but narrower than 

 the lobes (female). Tegmina abbreviate, a little longer than the prc- 

 notum, overlapping, with angularly separated dorsal and lateral fields, 

 particularly in the male, ovate-lanceolate, apically bluntly acuminate, 

 the costal margin rotundato-angulate, cinereo fuscous, the dorsal field 

 often wholly cinereous; wings briefer than the tegmiua. Fore and 

 middle femora not greatly tumid in the male; hind femora testaceous 

 or luteo-testaceous, rather broadly and distinctly bifasciate with fus- 

 cons or blackish fuscous, sometimes suifused on the upper face, the 

 inferior face pale reddish, the genicular arc black; hind tibiae bright 

 red, at extreme base infuscated, with a fuscous patellar spot, followed 

 beyond by a broad but not very conspicuous pallid annulus, the spines
