new Oriental llomoptera. 641 



narrow, 'prominently longitudinally ritlo;ecl ; clypeiis slightly 

 longer than face ; mesonotum obscurely tricarinate ; poste- 

 rior tibiie distinctly spined beyond middle; teguiina about 

 three times longer than greatest breadth, the apical margin 

 subtruncate, the inner margin slightly dilated beyond clavus; 

 wings short, extending a little beyond the clavus of tegmen. 



Long., excl. tegni., \\ mm. ; exp. tegm. IS mm. 



Ilah. N.W. India (Drit. Mus.). 



Allied to Z. ;/t7m, Dist., from Ceylon, but a smaller species, 

 the tegmina less broadened, the venation darker, the apical 

 veins also quite different, being much more strongly oblique 

 in gilca than in spectra. 



ROBIGUS, gen. nov. 



Head narrow, vertex strongly projecting in front of eyes, 

 a little broadened anteriorly, tlie lateral margins distinctly 

 acutely raised, the apical angles slightly ))ronunent; face 

 long and narrow, the lateral margins distinctly raised, longer 

 than clypeus, which is centrally ridged; pronotum narrow, 

 the lateral margins ampliated and distinctly forwardly pro- 

 duced on each side of eyes ; mesonotum tricarinate ; abdomen 

 with the segmental incisures profound, above with tli3 apical 

 area narrowed and angulaled ; legs of moderate length, 

 posterior tibire not spined; tegmina more than three times 

 as long as bioad, with distinct series of apical and subapical 

 cells, two longitudinal cells at end of radial area, and above 

 these the contour of the costal margin is distinctly broken by 

 an irregular, raised, longitudinal, cellular interspace ; the 

 tegminal apices are slightly narrowed and rounded; wino-s 

 shorter and a little broader than tegmina, the venation com- 

 plicated by the vein at end of radial area being coucavely 

 sinuated and bifurcating at about half its length, forming a 

 marginal cell, before apex a transverse vein defining three 

 apical cells. 



A genus to be placed near Interavima, Walk. 



liohigus sanguineus, sp. n. 



Body and legs sanguineous, mottled with ochraceous, the 

 tibicfc and tarsi ochraceous, the apical area of the abdomen 

 above (excluding apex) pitchy black; tegmina ochraceous, 

 much suffused with sanguineous, the latter coloration more 

 prominent on the costal and apical areas and in some macular 

 markings on disk, on apical margin two or three ratiier 

 obscure greyish spots ; wings sanguineous, with their extreme 

 bases ochraceous.
