Malipatil; 1 female, “at light, Pusa Bengal [now Bihar state] 14.vii.06 [1906] at light, Y.R.E”; 1 male, “at light, Pusa Bengal [now Bihar state] x.08 [1908], T. N. S.” 1 male [Malipatil coll.] in VAIC, all remaining specimens in IARI collection.
Redescription. Colouration: Head and antennae brownish ochraceous (Fig. 1); antennae with apex of second, entire third, and fourth segments excluding bases and apices more or less fuscous (Fig. 4); pronotum ochraceous, anterior area reddish ochraceous with two central longitudinal fasciae black on anterior area and brownish on posterior area; scutellum ochraceous; corium pale ochraceous with scattered black speckles, and apical angle, black; membrane hyaline; abdomen above pale reddish; connexivum ochraceous; body beneath and legs ochraceous; head and prosternum with an oblique sublateral line; abdomen with a broken sublateral line pale sanguineous.

Antennae rather short, 1st segment slightly more incrassate than uniformly thickened 2nd and 3rd segments, 4th segment slightly fusiform; 1st and 2nd segments with short scale-like pubescence, 2nd segment in addition with sparse bristle-like setae in apical area; 3rd and 4th segments with dense pubescence and a few erect bristly setae; length of segments: I 0.30, 0.32; II 0.80, 0.96; III 0.50, 0.62; IV 0.64, 0.80.
Thorax: Pronotum coarsely punctate with a subanterior transverse slightly curved ridge, without a distinct narrow line on each calli (Fig. 2), median length 0. 94, 1.17; width at posterior margin 1.61, 2. 0 7. Scutellum (Fig. 1) coarsely punctate with an indistinct central pale longitudinal line; length 0.73, 1.01; width 0. 87, 1.20.

Venter slightly fuscous (Fig. 6), covered with coarse sparse punctures, somewhat thickly punctate on lateral areas.
Male genitalia: Pygophore as in (Fig. 7). Paramere sickle-shaped (Fig. 8). Aedeagus (Figs. 9–12).
Distribution. India: Calcutta, Pusa Bengal [now in Bihar state], and Delhi.
Notes. In all the somewhat damaged and faded specimens examined in the present study, fuscous or black markings or speckles on head, pronotum, scutellum, and hemelytra are considerably variable in intensity and size; in some they are almost indistinct, particularly in the male than in the female specimens. The head and pronotum with a Y-shaped fascia, as mentioned by Scudder (1957b), is not clearly present in any of the specimens examined in the present study. The distribution in India is now extended to Pusa and Delhi.
