Thermesia dorsilinea, new species. (Fig. 41, No. 10.)

 joins a similar costal patch at the end of the cell, through which 

 the outer line runs, clay-colored, angled at vein 6, expanding a 

 little and marked with brown below vein 1. Traces of submar- 

 ginal line, whitish, waved, placed far from the margin. A row 

 of minute terminal black dots. Hind wing with a broad mesial 

 band of mixed brown and clay-color, distinct on the inner two-

 second narrower one starts on the middle of the costa, curves to 

 touch the outer line below the middle of the wing and reaches 

 the inner margin near the base; a yellow streak between these 

 lines above the subcostal vein. A narrow waved subterminal 

 line, incurved opposite the cell, inwardly dentate on vein 3, run- 

 ning inward on vein 2 nearly to the transverse line, and along
