Antliopsyclie demarjore, Felder, Eeis. Nov., Lep. ii.p. 186 (1865). 



The females associated with T. ejphyia iu the British Museum 

 appear to me to be Avrongly placed, as they are inseparable from 

 those of the very different T. microcale. But!. T. dcmagore, with its 

 reduced black markings above and pinkish underside, I take to be 

 the dry-season form of this species. Kecorded from Dongola and 

 Upper Egypt. 



.50. Teracolus liagore. 



Pontia liagore, Klug, Symb. Phys., Ins. pi. vi. figs. -5-8 (1829), 

 This distinct little species, which belongs to the T. evarne group, 

 seems to be decidedly scarce. Klug records a single male from 

 Dongola, there is a male from Upper Egypt in the British Museum, 

 and I have seen one other from Suakin.

T, aiu-o represents the wet-season form, and T, topha ( = heis- 

 kamma) the dry. As Mr. Trimen has pointed out, the two types of 

 T. syrtinus, Butl., from Lake Nyasa and Senegal, are inseparable 

 from T. auxo ; but the remaining specimens associated with them 

 in the British Museum appear to me to be referable to the nearly 

 allied T. evarne (Klug). The above specimens of P. syrtinus are 

 the only examples of true T. auxo that I have seen from localities 

 north of the Zambesi. To the south of that river it is plentiful iu 

 suitable spots throughout the eastern side of the continent. 



52. Teracolus incretus. 



Teracolus incretus, Butler, Ent. Mo. Mag. xviii. p. 146 (1881). 



Callosime vulnerata, Staudinger, Exot. Schm. pi. xxiii. (1884). 



This handsome species is the Central-African representative of 

 auxo, and inhabits a broad belt of country lying between Mombasa 

 and Victoria Nyanza. It has the bright yellow colouring of the 

 Southern species, as opposed to the whiter tints of T. evarne (Klug) ; 

 but differs in its much larger size and in the black markings on 

 primaries, there being no sign of black on the inner edge of apical 

 patch, and the hind marginal border being narrow, not extended to 

 posterior angle uor dilated as iii T. auxo. In the latter characters
