Diagnosis

Pale yellowish brown suffused with reddish. Pronotum yellowish with greenish and reddish tinges. Scutellum reddish, obscurely pallid in the middle and posteriorly. Anterior and interior legs more or less dark, posterior legs more or less pale. Tegmina subhyaline, colorless; basal third of corium and clavus and apex of clavus dark brownish (more or less ruddy), apical fourth yellowish brown. Granulations dark brown. Pronotum very lightly carinate longitudinally; much wider than head and eyes. Scutellum shallowly channelled along its anterior three fourths, posterior fourth carinate. Length: 6 3/4–8 mill. (Kirkaldy 1906).

Female. Postclypeus convex, with dense, moderately coarse punctures; lateral area strongly descending, with about 11 transverse impressed lines (including 5 on tylus). Gena and lorum densely, longly haired and moderately coarsely punctate; relative breadths of pleurostome and lorum and length of gena proper 4.5 : 3 : 3. Crown irregularly punctate-rugose; occipital margin strongly reflexed; tylus somewhat flattened; side piece of vertex nearly plane, anteriorly rounded off to antennal ledge; tentorial pit roundish, very shallow; ocellus distinctly closer to tylus than to occiput; ocellar area strongly raised at middle. Pronotum with intersecting, strong rugae, no distinct punctures; ante-callus area slightly depressed, finely rugose, and with a distinct submarginal furrow running parallel to anterior margin; lateral area irregularly punctate-rugose; posterior margin very broadly sinuate at middle. Scutellum moderately convex, wrinkled; discal depression large, longer than wide; apical 1/4 smooth, weakly concave, laterally weakly reflexed. Tegmen coarsely, very densly and deeply punctate at basal 2/5 and along costal margin, elsewhere very sparsely so; costal cells and longitudinal veins with scattered brown granules which are slightly wider than veins; basicostal depression rather shallow. Relative lengths of pronotum and scutellum 32 : 32; relative breadths of head, pronotum and scutellum 38 : 50 : 22. Body length 6-8 mm.
Male. Similar. Tegmen paler. Relative lengths of pronotum and scutellum 30 : 30; relative breadths of head, pronotum and scutellum 34 : 46 : 21. Body length 6.5 mm. (Maa 1963)
