Head full and rounded in front, with no well-marked interpalpal tuft. 

 Antennae usually ciliated (in G. Sabiniaria with short, fine, spatulate, ciliated 

 pectinations). Palpi broad and long, porrect, extending well in front ot 

 the head; third join* small, conical, pointed. Fore wings with the costa 

 straight, a little arched toward the slightly-produced apex: outer edge oblique. 

 Hind wings long, the inner edge much longer than the outer, which is full 

 and rounded, with the apex much rounded. Venation: two large, well- 

 marked, subcostal cells (in G. Sabiniaria the inner cell very small); the second 

 subcostal venulearises half-way between the end of theouter cell and the origin 

 of the third subcostal venule; the posterior (fiscal venule bent (not curved) 

 near the middle. Hind Legs moderately thick: tarsi slightly shorter than the 

 tibia* (in G. Sabiniaria the tarsi an; a little longer than the tibiae). Abdo- 

 men moderately stout, with a well-marked tuft of hairs at the tip, forming in 

 '/. Sabiniaria a larger tuft than usual. Coloration: stone-gray, often with 

 golden scales, and with numerous, wavy, zigzag lines. Hind wings lineated 

 or clear. 



This genus embraces some of (he largest species of the subfamily, and 

 differs from Evpithecia, on the one baud, in the large hind wings, with the 

 long inner edge, and from Plemi/ria, on the other, by the full, rounded hind 

 wings. The palpi are stouter and shorter than in Thera. The \ouii, sub- 

 acute fore wings, and the large hind wings extending beyond tin; end of the 

 abdomen, and the peculiar style of marking, mimicking the colors of lichen- 

 clad rocks, distinguish it. 



The species are more liable to tie confounded with those of Pdroj'hom 

 than any other genus; but they differ in the shorter, stouter, blunter palpi,
