Allotype. — cf; same data as type. [Hebard Collection.] 



Description of Allotype. Differing from the description of the type in the fol- 

 lowing features. 



Fastigium with greatest width subequal to length of same from eye inter- 

 space, in form distinctly acute-angulate when seen from the dorsum, the im- 

 mediate apex blunt and rounded, the dorsal surface of fastigium broadly but 

 shallowly impressed, the margins appreciably and the median carina sUghtly 

 elevated: lateral foveolar surfaces hardly visiljle from the dorsum, not reflected 

 toward the dorsal surface, impression of same as in female but more con- 

 centrated and limits more evident; fastigio-facial angle, when seen in profile, 

 more narrowly rounded than in female, face more retreating: frontal costa 

 narrower, faintly constricted at median ocellus, distinctly sulcate for a con- 

 siderable distance dorsad and a lesser distance ventrad of the same : eyes with 

 greatest length subequal to the greatest depth of the infra-ocular portion of 

 genae, cephalic margin of basal outline less strongly truncate, more arcuate: 

 antennae about two and two-thirds times as long as the pronotal disk, flattening 

 of segments less extensive than in female. 



Pronotum with cephalic margin of disk weakly obtuse-angulate, caudal 

 margin of same with angulation obtuse but slightly more marked in degree than 

 in the female: lateral lobes with ventral margin oblique truncate cephalad, 

 caudal margin faintly concave. Tegmina falhng short of the apex of the 

 abdomen by about the length of the pronotal disk, the discoidal field weakly 

 inflated; greatest width of marginal and discoidal fields combined subequal 

 to greatest depth of caudal femur, greatest width of these fields at distal fourth; 

 marginal field with expansion regular from the very weak basal lobe to the 

 distal fourth, thence the marginal field is rather sharply emarginate and nar- 

 rowed to the apex of tegmen. Wings greatly reduced. 



Metasternal interspace slightly more narrow than in female. Al^donien 

 compressed, carinate dorsad, non-carinate ventrad: supra-anal plate trigonal, 

 apex acute, lateral margins sinuate and broken at proximal third, a transverse 

 depression present here, a broad medio-longitudinal one present proximad and 

 the distal third of plate is slightly elevated: cerci simple, heavy, styliform, 

 reaching to apex of supra-anal plate: subgenital plate weakly compressed, 

 faintly rostrate, apex bluntly produced. 



Caudal femora with length slightly more than three times as long as the pro- 

 notal disk, caudal tibiae with twelve to thirteen spines on external, and twelve 

 on internal margins. 



Color Azotes. — ^General cojor ranging from argus brown to mummy l)rown, 

 occasionally (type and allotypic male) with dorsal surface of head, pronotum, 

 abdomen and greater portion of tegmina ochraceous-tawny to buckthorn brown. 

 Rarely (allotypic male) this paler area is hardly indicated on head and prono- 

 tum, and is tawny on the abdomen and dull buckthorn brown on tegmina. 

 Face occasionally (allotyjiic male) paler — buckthorn brown, this due to a reduc- 

 tion in the number of dark specklings which deepen the general tone in the 

 other individuals: antennae ochraceous-tawny to russet, darkened with prout's 

 brown distad : eyes mars brown to saccardo's umber, but little contrasted with
