126 ME. G-. T. BETHUNE-BAKEE : A REVISION OE THE 



Hab. Burma. 



Expanse, 6 58, $ 60 mm. 



The only difference between the two types of this species and agnis is that the blue 

 in the female is of greater extent than is usual in Felder's insect and that it is paler 

 and bluer, and I have but little doubt that the name should be sunk under agnis 

 Felder.

Hab. Tameang-Lajang (S.E. Borneo). 



Expanse, d 57, ? 54 mm. 



From agnis Feld. this species may be easily distinguished by the quite different colour 

 of the upperside, which is very dark ; the underside pattern is somewhat similar, but 

 the spots of the transverse bands of both wings are more confluent, especially in the 

 secondaries. In agnis both these fascia are very distinctly spotted. The types are 

 now in my collection.

Hab. Borneo (Tameang-Lajang, Kina Balu) ; Baram River. 



Expanse, d 54, $> 50 mm. 



This species is very near tameanga Bethune-Baker, but may be separated by the 

 difference in the colour of the upperside, which is dull violet, and by the broadish 

 borders ; whilst beneath the pattern is similar, but the spots are larger, especially those 

 at the base and the cell-spots. The ground-colour is paler, making the pattern stand 

 out much more prominently. I have, since my first description was written, seen two 

 females from the Baram River (N. Borneo) which I believe to be this species ; they are 

 in Mr. Rothschild's Museum, but are very darkly marked. The types are in my 

 collection.

Hab. Borneo ; Perak.

d . Upperside : both wings purplish blue, in a side light dull and rather dark : 

 primaries with the costa of medium width, dark brown, and a broad outer margin 

 rather wider at the apex ; secondaries with a very broad brown costa and rather less 

 broad outer margin ; tail brown, tipped with white, of moderate length. Underside : 

 both wings ochreous-brown, with darker spots palely encircled. Primaries with three 

 large increasing cell-spots, below each of which is another, the first two obscure, the
