Ceylon and Java. Types in B. M. 



I am not satisfied that this is more than a variety of 

 A.mcludens. We have specimens from Java and the Nil- 

 giris of what may be a variety of this species, but in which 

 the pale belt across the primaries terminates just above the 

 submedian vein, its inferior extremity being defined by a 

 black line emitted from the black patch terminating the dark 

 subbasal band. 



3. Avatha curvifera.

Ceylon, India, Nilgiris. Types in B. M. 



The types differ in nothing beyond size and depth of 

 colour, i/. curvifera being the darkest, A. expectans the 

 smallest, and 0. frontalis the palest and largest. 



4. Avatha tepescens.

Java {Hiibner) ; Ceylon and Nilgiris. In B. M. 



We have a species from Borneo very closely related to 

 this, but I think distinct ; it is decidedly larger, and the 

 black subbasal band across the primaries is widened into a 

 broad, internally deeply indented belt edged with silvery 

 whitish ; the centre of the wing is occupied by a white band 

 bounding the aforesaid belt externally and shading into olive- 

 green below the second median branch ; on the inner margin 

 beyond this band is a reversed conmia-shaped black spot, 

 thus o , and the submarginal area is more lilacine and shows 

 no trace of the zigzag submarginal stripe ; the fringe of 

 secondaries is uniform, having no white anal patch, and the 

 head, collar, and tegulas are ferruginous. Expanse of wings 

 59 millim. 



This species may be called Avatha pulcherrima.
