about one and a half times as long as broad, concavely sinuate at 
inner margins of eyes, two distinct central carinations which 
neither reach base nor apex and which moderately converge poste- 
riorly, a broader but less sharply defined sublateral carination on 
each side.

Body above brownish-ochraceous ; body beneath and legs a

brown; tegmina shining fuscous-brown, the basal area more or less 
paler and more ochraceous, two spots on apical half of costal 
membrane, one at apex, two linear before apical margin, a larger 
irregular spot before apex of clavus, and a variable cluster of 
smaller spots nearer base, white; wings subhyaline, the veins, apex 
and margin fuscous-brown ; face shorter and comparatively broader 
than in the preceding species M. confusa, the carinations similar ; 
mesonotum finely tricarinate ; lateral margins of vertex acute.

Genus ORYXANA, gen. nov. 
Vertex a little longer than broad, the lateral margins strongly 
ridged’; eyes very large, only a little shorter than vertex, reaching: 
base but not overlapping the pronotum, face posteriorly about as 
broad as long, obliquely widened from base and suddenly ob- 
liquely directed inwardly a littie before clypeus, centrally longi- 
tudinally carinate, the carination continued through the clypeus 
and with a short curved carination on each side scarcely reaching 
middle ; pronotum centrally about as long as vertex, the anterior 
margin angularly produced between eyes, the posterior margin 
convexly rounded ; mesonotum about as long as pronotum, poste- 
riorly angularly produced; tegmina about one-third longer than 
broad, the costal margin and apical angle broadly convex, apical 
margin obliquely truncate, the inner angle acute, claval margin 
nearly straight, costal membrane, wider than radial area, with 
oblique but furcate veins, remaining area of tegmina more or less 
reticulately veined ; wings considerably shorter than tegmina, two 
transverse veins on upper apical area.
