Diagnosis

Greyish testaceous, vertex, lateral margins of frons (spotted with testaceous), markings on clypeus, etc. middle part of pronotum and of scutellum, extreme base of clavus, some obscure, small markings on tegmina (especially on apical and costal margins), some more or less obscure markings on legs and abdomen — blackish. Underside yellowish testaceous, frontal carinae pale ferruginous. Tegminal veins more or less closely speckled with sanguineous. Wings pale smoky. Vertex a little longer than wide; lateral margins of vertex and frons acutely elevated vertically; on the front within these are 3 carinae united basally acutangularly, diverging a little posteriorly and roundly uniting again. Frons nearly twice as long as wide, wider posteriorly than anteriorly. Rostrum reaching to posterior coxae. Upper apical angle of tegmina about right angled. Length: 8 mm, height in profile about 4½ mm. (Kirkaldy 1906).

The shape of the sutural angle of the tegmen is the easiest way of telling the two species apart. In this species it is slightly obtuse but in C. acutipennis it is acute and somewhat prominent.
