in the male, the yellow on the fore wings suffusing the wing through- 

 out, and the entire surface of the hind wings deepened to saffron- 

 colour. 



Expanse of wings, c? IjVj 2 li inch.

14. Teracolus yerburii, n. sp. (Plate XXXIX. cJ, fig. 12.) 



Haithalkim near Aden, March 1883. 



cJ . Near T. daira, Klug. Is, however, quite distinct, differing 

 from both the plates and the description in having the base of all 

 the wings deeply irrorated with black-brown, which extends in the 

 form of a deep band along the inner margin of the fore wings to the 

 black spot on the interno-median interspace. In the hind wings by 

 having a large black-brown spot on the costa corresponding to the 

 spot on the fore wings, which also forms a limit to the basal irrora- 

 tions, the irrorations on this wing covering the entire basal third. 



Expanse of wings, \^-^ to If'y inch. 



In coll. C. Swinhoe. 



Group 8a. Type Teracolus liagore, Klug. 



15. Teracolus saxeus, n. sp. (Plate XL. d $, figs. 1 & 2.) 

 Haithalkim, near Aden, March 1883. 



Near T. liagore, Klug. 



<S . Differs above in liaving the base powdered with black-brown, 

 in having a smaller apical patch, and in having the outer black-brown 

 border thicker and dentated, and with the hues running halfway- 

 through the patch on the veins. 



Below it differs in having a black spot on an orange ground at 

 the end of the discoidal cell in the hind wings, and the inner half 

 of the costa of the same colour ; whereas in T. liagore, both in Klug's 

 plate and in the only specimen in the British Museum, the hind 

 wing below is immaculate. 



2 . Has the apex of the fore wings more rounded ; otherwise above 

 and below it is similar to the male, but with all the colours paler. 



Expanse of wings, S $ lyV to 1^^ inch. 



In coll. C. Swinhoe. 



Klug's plate of the female of T. liagore is undoubtedly a mistake : 

 the insect therein represented does not belong] to this group at all, 

 but is a male of the 2\ daira group. 



16. Teracolus odysseus, n. sp. (Plate XL. c?, f. 3.) 



White Nile (Petherick). 



Allied to T. glgcera, Butler. 



cJ . AVithout the deep band on the inner margin of fore wings, 

 with the black outer border of the apical patch deeper, and with an 

 inner band interrupted above the middle; and in the hind wing in 

 having the black macular border less pronounced. 



5 . Much resembles a faded female of 1\ glycera ; the apical
