Pale brownish yellow, cheeks with a small punctiform black spot. 

 Crown somewhat longer than pronotum, parallel-sided, projecting 

 beyond the eyes for about one-third of its length. Scutellum a 

 little longer than crown. Elytra yellowish hyaline, a trifle longer 

 than the abdomen, parallel-sided, their apex obtusely rounded ; in 

 the male with a spot at the apex of the clavus, a spot on the costa 

 at the base of the first apical area, and another at the apex of the 

 middle nerve of the membrane, black ; in the female with a large 

 irregular patch at the base, another at the apex of the clavus, and 

 an oval patch on the middle nerve of the membrane, black. These 

 markings have a strong tendency either to coalesce, or to disappear 

 leaving only a small black spot at the apex of the middle nerve of 

 the membrane. Upper side of the abdomen occasionally with the 

 base of some of the segments narrowly black. 



Macropterous form. — Scutellum nearly twice as long as pro- 

 notum. Elytra yellowish hyaline, one-third longer than abdomen, 

 apex of the clavus filled up with black. Length, 3 — 4 mm.
