and spots, whereas the ground-colour is very pale yellowish grey 

 with pale brown fasciae and a double row of black marginal spots 

 to each wing ; the two spots nearest to the anal angle sprinkled 

 with blue scales. The upperside is dull violaceous silvery blue. 

 Possibly JV. kerriana, Distant, is conspecific with If. angusta, but 

 unfortunately I have not a specimen for examination. The under- 

 side of the figiu-e given in Ehop. Malay, appears to agree well 

 with that of JV. angusta, but the upperside has a broader black 

 outer margin. 



JV. azureus, Eober, as figured by Herr Semper (Eeise Philip. 

 Insel. p. 177, pi. xxxiii. figs. 1, 2), and which we possess from 

 S. Celebes (Dohei-ty), is a closely allied species. Herr Eober's 

 figure and this one, however, do not agree very well.

Kina Balu ( Waterstr.) ; Labuan (Loiv) ; S.E. Borneo, near Ban- 

 jarmasin ( Walines). 



Kina Balu specimens are slightly darker on the upperside than 

 those from Labuan and S.E. Borneo. I have examined the type 

 of C. al-aha, and can find no character to distinguish it.

Sandakan (Pryer). 



I include If. beroe here on the authority of Messrs. Distant and 

 Pryer. Typically, I think it can be distinguished from iV. atratus 

 by the paler ground-colour of the underside and by the fascia 

 being much wider.

 The figure given in the P. Z. S. is a very bad one and bears but 

 slight resemblance to the insect. It is, in my opinion, although
