The salient points in Pallas's brief description are as follows:—“Cinereus … Frons hirtella. Antennae triarticulatae; extremum trinode, basis vero pilis nigris subpennata. Palmi [? palpi] nulli: ensis nudus … basi pilosus. Pedes longissimi, grisei, posticis corporis fere tripla longitudine, praesertim tarsi, elongati. Alae lanceolatae, cinerascentes, venis hirsutis ad crassiorem marginem nigro maculatae … Comes prioris [C.caspius, = O.dorsalis, Mg.], rarior red ferocior.”
