2 transverse rows of from 4 to 7 spots each, beyond the middle, sub-

Gyrestis thyodamas, Boisd.— Of very slenderyand delicate appear- 

 ance. Head and thorax pale olive-brown, with 3 longitudinal darker 

 stripes. Wings white, more or less suffused along the costa and apical 

 half of the outer margin of the forewing and the inner margin of the 

 hindwing with olive brown. Three very fine and irregular dark brown 

 lines crossing both wings, sometimes branching, 2 before middle and 

 1 beyond it, a stronger line beyond these outlined outwardly on the 

 hindwing and on the lower third on the forewing with slightly 

 metallic slatey-blue. Between this and the three incomplete olive- 

 brown to dark-brown subterminal lines there are on the forewing 3 

 brownish spots towards apex with white centres and 3 yellowish- 

 brown spots with white centres and sometimes dark purple towards 

 the anal angle, while on the hindwing this space is more or less
