discalis. Walk., but with the fuscous-brown areas much reduced 

 aud brokeu, the hyaline space being thus much enlarged both 

 inwardly and outwardly and on basal area crossed by a narrow 

 oblique fuscous-brown fascia ; face with a central and two sub- 

 lateral carinations, becoming more or less evanescent posteriorly.

" Body reddish-brown ; face, abdomen, and legs paler ; pro- 

 notum aud mesonotum as in li. meUerhorgi ; tegmina hyaline, 

 vitreous with a yellow-brown pattern consisting of two transverse 

 fascia^ of which the subapical one emits two processes to the apical 

 margin, thus defining three large rounded hyaline marginal spots, 

 the first of these near apex is larger than that near the posterior 

 angle, four rounded hyaline spots on costal margin ; wings vitreous, 

 posterior margin slightly tinged with brown. This species resembles 

 R. meUerhorgi, but is larger, the costal margin flatly arched, before 

 the apex almost slightly sinuate, less rounded at apex, veins of 

 tegmina coloured with brown in vitreous portions, whereas they 

 are white in R. meUerhorgi ; also the white dots at the apices of 

 veins on apical margin are wanting, and there are only minute 

 marginal spots to be seen in the brown coloration on apical margin.''

Body piceous ; face, clypeus, and legs dull brownish-testaceous : 

 vertex of head mottled with brownish-ochraceous ; tegmina 

 opaque, piceous or piceous-brown, costal margin spotted \\\t\i 

 ocbraceous, a small subquadrangular white spot at end of radial 

 area, on disk a large greyish-white irregular spot followed by 

 mottlings of the same colour which extend to near base and along 

 the inner area, on the upper outer area of the large spot is a very 

 distinct rounded black spot, the two transverse lines on apical area 

 are sometimes brownish-ochraceous, and their interspace much 

 suflused with the same colour, in other specimens the apical area 

 is piceous aud the transverse lines faintly visible ; wings pale 

 fuliginous, sometimes a little paler near base aud on anal area : 

 face with the carinations fine but distinct.
