Hob. Sikkim; Burma (Bhamo) (Standing er). 



Expanse, 6 48-49, 2 46-48 mm. 



A close ally of adriana de Nicev. ; besides the difference in the outer margins, as 

 already indicated under that species, it may also be separated by the presence of 

 metallic-green scales at the anal angle, which are not present in adriana ; the markings 

 are more pronounced on the underside of the secondaries, especially the subbasal band, 

 which is generally very dark and well marked. 



This is another very local species, though of wider range than the last, as besides 

 specimens from Sikkim I have a couple from Bhamo (Burma). The genitalia are 

 closely similar to those of the previous species, but the fore portion of the clasps is 

 rather larger.

Expanse, d 47-50, 2 43-47 mm. 



$ . Upperside : both wings purplish brown, with a purplish-blue central patch, in 

 the primaries extending over the discoidal cell, the submedian and about half of the 

 median areas, in the secondaries extending just outside the cell and about halfway 

 beyond towards the outer margin. Underside precisely as in the male. 



Felder's species chinensis has for long remained practically unknown, and 1 was 

 surprised in looking at this type in Mr. Rothschild's Museum to recognise it as 

 probably moelleri de Nicev. I have since carefully examined it with a number of 

 de Niceville' s species and I have no doubt it is that insect. There are two slight 

 differences : in the type chinensis is a small light spot on the underside near the base 

 in the cell of the primaries, this is not present in ordinary moelleri de Nicev., but there 

 are indications of it in several specimens before me ; and in the secondaries the broad 

 dark band at the base is more broken up on its outer margin than is the case with
