tained but slightly more than three times in the greatest tegminal 

 length; costal margin strongly arcuate in proximal eighth, thence 

 broadly and very shallowly arcuate emarginate to distal third, thence 

 regularly and broadly arcuate to the rounded obtuse-angulate apex; 

 sutural half of distal margin oblique rotundato-truncate, rounding 

 into the sutural margin, which is broadly arcuate, flattened and 

 straight mesad. Wings faintly surpassing the apices of the tegmina, 

 the distal sections as coriaceous and pilose as the tegmina, Proster- 

 num unspined; meso- and metasternal lobes small, rounded laterad. 

 Disto-dorsal abdominal segment large, half domed, dorsal surface 

 with a pair of lateral patches of long pile, a medio-longitucUnal im- 

 pressed cuneiform area placed on the distal half, the free margin 

 mesad supplied with a closely placed pair of slender processes, which 

 when seen from the side are tapering, sinuate, with a recurved apex, 

 these processes reaching as far caudad as the apex of the subgenital 

 plate and their bases placed on each side of the median impression of 

 the segment: cerci simple, tapering, weakly depressed, incomplete in 

 the type, sparse pilose: subgenital plate strongly produced in 

 median linguiform development which is flattened, clothed with long 

 pile and laterad of the base of which spring styles of a most striking 

 type; these being greatly produced, tapering, straight in their distal 

 third, thence regularly arcuate dorsad and mesad, with the apex 

 moderately decurving and produced in a distinct apical spine, the 

 whole of the styles long pilose; the right style is simple, the left is 

 compound, having a dorsal branch forking from the main style near 

 its base, faintly more than one-half as long as the main branch, fol- 

 lowing the principal arm in attenuation and curve but with an un- 

 armed apex. Cephalic and median femora unarmed beneath; ceph- 

 alic and median tibiae with three spines distad on each ventral margin. 

 Caudal femora short, robust, weakly tapering distad, ventro-external 

 margin with four to six spines, ventro-internal margin with three 

 large distal and four minute proximal spines; caudal tibiae with three 

 external and four internal spines on the dorsal margin. 



General coloration between ochraceous-buff and zinc orange, a 

 broad V-shaped patch dorsad between the eyes and a pair of broad 

 sinuate bars on the pronotum at the usual position of the lateral 

 shoulders and also covering the dorsal half of the lateral lobes, 

 bone brown. Ej^es blackish fuscous. Tegmina colorless, semi- 

 transparent proximad on marginal and discoidal fields and translucent 

 washed with pale mummy brown distad; venation pencilled with 

 prout's brown, except immediately at the base of the tegmina, where
