138 ME. G. T. BETHUNE-BAKER : A REVISION OF THE 



This species is an exceedingly close ally of tounguva Gr. -Smith, but as I have only 

 seen about a dozen of each species, I have thought it better to keep them distinct. It 

 is quite possible, however, that further material may prove them to belong to one and 

 the same insect; in fact I believe this will prove to be so. They obtain in almost 

 exactly the same district ; both are local, this species being only recorded from Burma, 

 and tounguva from Burma and the Andaman Isles.

Ilab. Toungu ; Burma ; Andaman Isles. 



Expanse, d & $ , 44-47 mm. 



In some specimens the underside is irrorated slightly with ochreous, whilst the 

 upperside is occasionally of a violet-blue. Both sexes are almost the same. The 

 markings of the underside are very close to perissa Doh., and also to asopia Hew. ; 

 from the former it can be distinguished by the difference in the transverse band of the 

 secondaries, and also by the colour of perissa being clear, smooth, cinnamon-brown 

 beneath, whilst tounguva has more or less of an irrorated or dusted appearance. 



Asopia Hew. is sufficiently distinct not to require differentiating. As mentioned 

 under the previous species, I believe that tounguva will prove to be one and the same 

 as Doherty's insect.

Ilab. Moulmein, Upper Tenasserim, Tilin Yaw, and Bhamo (N. Burma). 



Expanse, d & 2 , 46-48 mm. 



d . Upperside ; both wings dull sublustrous violet, rather dull in tone ; primaries 

 with the costa narrowly, posterior margin broadly, apex more broadly dark brown ; 

 secondaries with costa broadly, and posterior margin less broadly brown ; abdominal 

 margin greyish. Underside: both wings cinnamon-brown, with darker spots palely 

 encircled. Primaries with spots darker than secondaries, and tinged with violet; three 

 discal spots, below which the subnicdian area is dark, below the third spot is another 

 adjoining it ; transverse band very regular and even in width, widish, slightly curved 

 near the costa, and with a slight outward inclination ; below the submedian nervure is 

 an obscure spot beneath the band ; submarginal band dark, but obscure ; submedian 

 area pale. Secondaries with spots paler than in primaries, one on the costal base, four 

 basal spots, the upper two very small and dark, followed by four larger ones; cell
