Gen. 3. Pyrrhorhachis. 



Fyrrhorhachis Warr., Nov. Zool. 1896, p.292. 



Face smooth. Tongue well developed. Palpi long, slender; 

 terminal joint elongate, especially in ^. Antennas in q pectinate, 

 apices simple; in 2 simple. Thorax and abdomen not crested; 

 thorax not hairy beneath. Posterior tibiae with all spurs present. 

 Frenulum and retinaculum obsolete in both sexes; hindwings 

 Avith a strong costal expansion at base. Forewings with 3 and 

 4 stalked, 11 from cell or stalked with 7, 8, 9, 10 before 6, free 

 or anastomosing with 12; discocellulars not separated on vein 5. 

 Hindwings markedly elongate with termen strongly rounded; 3 

 and 4 stalked, 6 and 7 stalked, 8 approximated to cell near base 

 discocellulars scarcely angled, but slightly oblique. 



Type Eucrostis i-)ijrrhogona Wlk. In the shape of the hind- 

 wings, this agrees with Comostola chlorargyra, but differs in the 

 form of the cell of the forewings. I regard the genus as ancestral 

 to Comostola.
