Genotype: Cycasia oculata , new species.

This genus will not run down satisfactorily to any in Hendel's key to the genera of the family (Wien. ent. Zeitung, 33: 73, 1914). It undoubtedly belongs to the segregate or tribe Euribiini of Hendel's latest paper on the family (Die Fliegen der palaearktischen Region, 49, Trypetidae, 1927 ).
