Description: A brownish species that has four to six noticeable black spots on the otherwise whitish margin of the vertex. The underside of the abdomen, thorax, legs and face are a tawny yellow, and the edges of the abdominal and thoracic segments are marked lightly to heavily with a fuscous color. The pronotum has six darkened longitudinal bands or stripes, and the scutellum is usually darkened near the anterior angles. The wings are a tawny yellow to brownish color, with pale wing venation; note that some veins often crisscross to form small wing cells. There are three anteapical wing cells (separating this species from Graminella, which only have two anteapical cells), with the middle one divided (the anteapical cells are the the row of cells preceding those on the edge of the wing; note the middle cell is divided in two). The female pregenital sternite has the posterior margin more or less trilobed with the central lobe usually shorter and broader than the others. Adult males are 4.6-5.0 mm long, while females are 5.0-6.0 mm. (Kramer 1971)
