Giierin,* but the coloration of the upperside is quite difierent, being- 

 dark shining purple, while A. jesous is " pale purple-blue." The 

 details of the markings on the underside are also very different, 

 especially the small round spot in the middle of the cell of the 

 forewing in A. jesous is developed into a large oblique band extending 

 far below the cell in A . aslalis ; the discal band is also different, in the 

 latter it is formed of conjoined rounded spots, in A. jesous there are 

 no spots at all, the band being formed of two parallel whitish lines. 

 In the hind wing there are three prominent costal spots in A. asialis^ 

 in A. jesous there are only two, the one in the first subcostal inter- 

 space heing small and inconspicuous in the latter species. 1 might 

 here note that A. jesous has recently been procured in Upper Burma 

 at Myingyan and in the Lower Chindwin Valley, which is a new 

 locality for it. It appears to occur over a greater portion of Africa. 



Described from a single example in the collection of Hofrath

16. NACADUBA NANDA, n, sp., PI. S, Fig. 23, $. 



Habitat : N.-E. Sumatra. 



Expanse : $, 1-0 to 1*1 inches. 



Desceiption : Male. Upperside, both toings pale lavender-blue, 

 of the same shade as in the common N. atrata, Horsfield ; with a very 

 narrow outer black border as in that species. Foreioing with the 

 costa very narrowly black, the black outer border slightly widened out 

 at the apex. Hindwing, the three anal interspaces bear a prominent 

 anteciliary white thread as in N. coclestis, de Niceville ; tail black, 

 tipped with white. Underside, both wings greyish-brown, the m'^rkings 

 thin, very prominent, and pure white. Forewing with a pair of lines 

 crossing the discoidal cell about its middle and reaching the submedian 

 nervure ; a pair of lines at the end of the cell ; two or three costal white 

 dots anterior to the latter ; a discal pair of lines from near the costa 

 to the submedian nervure, strongly fractured and shifted inwardly 

 towards the base of the wing at the second median nervule ; the 



* The following species appear to be synonyms of A. jesous, Gue'rin : — Lycwna gamra, 

 Lederer ; Azaims crameri, Moore ; and Lampides agave, Walker. Captain E. Y. Watson 

 informs me that Lampides sigiUata, Butler, placed by me as a synonym of A. jesous, is quite 

 distinct from that species.
