of the Genus Teracolus, Sioaxns. 389 



Tlic wct-scason variety has the apex of tiic primaries and 

 the secondaries ^^reenisli yellow instead of pinky bulF on the 

 untler surface; intermediate specimens also occur, and it may 

 be doubted wlu-ther tlie three forms do not all fly simul- 

 taneously, as is frequently the case in very dry rci^ions. 



There arc altogether seventeen specimens in the Museum 

 series. 



3. Teracolus ocellatas. 

 Teracolu-i ocellatiis, Butler, P. Z. S. ISSo, p. 767. 



A single wet-season male of this still rare species was 

 obtained by Mr. J. G. Tlirupp in Somaliland in ISSi; I 

 have since seen a second ex;iniple in Miss E. M. Sharpe's 

 collection. I had long expected to see this butterfly before 

 it actually came to hand, as I felt certain that some inter- 

 mediate form must exist between the salmon-coloure 1 T. pro- 

 trdcfufi and the half-salmon, half-white 7\ pkisadia. As 

 might be expected, T. ocellatas is somewhat nearer to T. pki- 

 sadia than to the Indian species, both in outline and in the 

 general pattern of the jirimarics. The dry-season form is at 

 present unknown, but it is quite possible that, as in 7'. phi- 

 sadia, it may only represent the female phase of the species. 



4. Teracolus pJnsadia. 



Teracolus phisadia, Godart, Eiic. Metli. ix. p. 132 (1819).

 Grand. Madag. p. 284, pi. xli. tigs. 10, 10 a ,'1887). 



The male of this species is a wet-season form and the 

 female (in all its varieties) invariably dry-season ; of course 

 they all fly together at the same time. The species occurs 

 abundantly in Arabia and ranges to Syria. According to 

 Mr. JMarshall it also occurs through Abyssinia to Senegal, 

 but I have never seen an African specimen ; its reputed 

 occurrence in ]\Iadagascar is doubtless due to an error in the 

 labelling ot a collection from Aden containing single examples 

 of many species which have been thus included in M. Gran- 

 didier's splendid work by M. Mabille. It would^ indeed, be 

 remarkable if Adenese species could leap over Somaliland 

 and the intermediate sea to Madagascar without appearing 

 upon the African continent.
