92. TeEACOLUS LEO. 



Teracolus leo, Butler, Ann. & Mag. Nat. Hist. ser. 3, vol. xvi. 

 p. 397(1865). 



Wet-season form. 2 , Taru, IQth December, 1896. 



Dry-season form. 5, Mbuyuni, 14th June, 1897; c? 6, Voi, 

 4th July, 1897. 



The diy form is quite new to science (excepting for the single 

 starved and faded male without locality noted in my Eevision of 

 the genus, cf. Ann. & Mag. ISTat. Hist. ser. 6, vol. sx. p. 501, 

 1897). The male at this season chiefly differs from that of the 

 wet-season in the bluer tint of the grey basal area of the primaries, 

 but the orange is sometimes carried above the first median branch 

 and the dusky submarginal markings are sometimes wanting ; the 

 underside differs in its flesh-coloured suffusion, which is very well- 

 defined at apex of primaries and over the basal, costal, and internal 

 areas of the secondaries. The female of the dry form resembles 

 T. ccelestis of Swinhoe (the dry form of the female of T. halimede), 

 but has the discal black spots across the primaries widely 

 separated from the outer border by a broad intervening belt of 

 the yellow ground-colour : on the iinderside the apex of the 

 primaries and the whole of the secondaries are fleshy brown, and 

 the transverse spots are much darker than in T. ccelestis. 



93. Teeacolus tenosus. 



S . Iclmais venosa, Staudinger, Exot. Schmett. p. 43, pi. xxiii.

 (1896). 



d c? 2 S , Taru, 22nd November ; 13th, 16th, 18th, & 19th 

 December, 1896. 



This species was badly needed for the Museum series ; there- 

 fore I was pleased to find that Mr. Betton bad secured a fair 

 number of specimens. 



94. Teeacolus heltolus, var. 



Teracolus helvolus, Butler, P. Z. S. 1888, p. 94. 



5 , Mbuyuni, 7th April : c? , Voi, 25th April ; between Voi 

 and Ndi (88 miles from Mombasa), 16th May ; Yoi, 4th July, 

 1897. 



These specimens are particularly interesting ; they are almost 

 as large as T. aurigineus, but of the exact pattern and coloration 

 of the dry form of T. helvolus. "We have corresponding examples 

 of the wet form obtained at Kilimanjaro ; a specimen of the latter 

 from Mombasa, however, scarcely differs in size from Somali 

 examples.
