12. TERACOLUS. 



Underside, — Similar to that of T. protracfus, but paler, with the black spots not 

 §0 much emphasised. 



Dr. Butler writes : " I had long eixpected to see this butterfly before it actually 

 came to hand, as I felt certain that some intermediate form must exist between the 

 salmon-coloured T. proiractus and the half-salmon, half-wliite T. phisadla. As might 

 be expected, T. ocellatns is somewhat nearer to T. phisadia than to the Indian 

 species, both in outline and in the general pattern of the primaries. The dry- 

 season form is at present unknown, but. it is quite possible that, as in T. phisadia, it 

 may only re23resent the female phase of the species." Expanse 1'5 inch. 



Habitat. — Somali Land.

Male. — Allied to T. protracfus, but is at once distinguished by the central 

 portion of the secondaries being white, with a broad black marginal border. The 

 basal area is slightly suffused with grey, extendiug along the sub-median nervure to 

 the hind-marginal border. 



The primaries are salmon-colour, but not nearly so pink or so bright as in 

 T. protractm; on the black marginal border, near the apex, are three light salmon- 

 coloured spots. There is a very distinct discoidal spot of black, and the base of the 

 wing has a pronounced shade of bluish-grey. 



Underside. — Resembles that of T. protractus. Expanse I'G inch. 



Female. — As Mr. Guy Marshall has pointed out in the "Proceedings" for 1897 

 (p. 10), there appear to be four forms of the female, all of which I have myself examined.
