features. Size larger: form and vestiture similar. Head slightly 

 deeper than width across the eyes: ocelli similar to those of the male 

 but slightly smaller. Pronotum with cephalic margin distinctly 

 arcuato-emarginate ; lateral borders of disk less distinctly diverging 

 caudad than in the male. Tegmina surpassing the tips of the caudal 

 femora: mediastine vein with eight rami; lateral field with five 

 free veins proximad: dorsal field with its width contained slightly 

 more than five times in the tegminal length. Cerci very elongate, 

 appreciably surpassing tlie tips of the wings: subgenital plate of 

 the type usual in the female sex of the genus, moderately compressed : 

 ovipositor in length surpassing that of the caudal femora by not 

 more than one-half the dorsal length of the pronotum, slender, 

 compressed; moderately decurved in proximal half, thence straight; 

 apical valves acute lanceolate, ventro-external surface of valves 

 shagreenous, the ventral surface crassly crenate-dentate, the 

 productions unequal and irregular in size, these arranged in several 

 series. Caudal tibise with the intercalated spinulations numbering 

 3- (or 5), 3, 2, 1 (or 2) on the external margin; 2, 3 (or 4), 1, 1, 

 on the internal margin. 



General coloration of the male buckthorn brown, of the female 

 between cinnamon-brown and dresden brown, in both sexes with 

 an overlying coloration of points of mummy brown and blackish 

 fuscous; pubescence pale golden. Head with the ocelli bordered 

 dorsad by a transverse, poorly defined band of fuscous; ocelli naples 

 yellow; eyes hazel, obliquely and rather irregularly barred dorsad 

 with three lines of fuscous; antennae multiannulate with mummy 

 brown on an ochraceous-buff ground, the contrast decided in the 

 male, hardly apparent in the female. Pronotum with the cephalic 

 and caudal margins beaded with fuscous except in the male, where 

 the caudal margin is unmarked dorsad. Tegmina with the median 

 vein strongly, closely and quite regularly beaded with blackish 

 fuscous, except in proximal fifth, spot at base of humeral trunk 

 blackish fuscous; dorsal surface with five oblique clouds of fuscous 

 in the female, the cross-veins largely lined with fuscous, in the male 

 no clouds are indicated and but a few cross- veins are pencilled; 

 lateral field of female with cross- veins pencilled with fuscous; 

 longitudinal veins all lined with dull ochraceous-tawny; intercalated 

 field washed with mummy brown in the male, nearly clear hyaline 

 in the female. Limbs thickly and closely speckled with fuscous in 

 the female, in the male this hardly indicated on the caudal limbs, 

 and much less distinctly so on the others than in the female; caudal.
