This genus of Geometræ resembles Tornos; the fore wings are larger and with the apices more produced; the external margin is longer and more oblique. The hind wings are narrow and lanceolate, with the apices pointed and a little depressed ; external margin straight or a little incurved. The female abdomen is like that of Tornos, and is thickly tufted at the extremity. This singular genus, which I name for Mr. Meske, may be at once distinguished by the pointed secondaries, narrower in proportion than in any other genus of the group, while the primaries are disproportionately large with straight costa and produced apices.
