926 DR. A. G. BUTLER ON BUTTERFLIES [Dec. 4, 



" This butterfly was taken on the same fig-tree as the preceding 

 species and its habits are almost identical. I saw also a second 

 example which I could not secure." (B. C.) 



We previously possessed only one female of this species : it is 

 new from Eastern Africa. 



50. Argiolaus crawshati, sp. n. (Plate LVIII. fig. 3.) 



$ . Nearest to A. trimeni ; of a more glistening and bluer tint 

 than in the female of that species, and with no trace of white in 

 the primaries, but the median vein and its branches more thickly 

 blackish-scaled ; secondaries with the costa and first two inter- 

 nervuiar spaces decreasingly whitish, the veins dividing them 

 blackish, the outer border about as broadly blackish as in A. lalos, 

 with two subconfluent orauge spots close to its inner edge towards 

 anal angle ; fringe grey tipped with white ; tails black with basal 

 fringe and tip white; anal lobe white with two black spots ; above, 

 and almost touching the latter, a blood-red spot irrorated with pale 

 blue ; abdominal area smoky greyish brown ; body similar to that 

 of A. silas. Underside chalky white, slightly sericeous ; the primaries 

 with dusky tipped fringe; two ill-defined submarginal blood-red 

 dashes indicating a submarginal line on median interspaces : 

 secondaries with an externo-discal blood-red stripe, augled on 

 subcostal and second median veins, terminating on first median 

 branch, where it is confluent with a tiny patch of blood-red and 

 opaline blue scales (probably indicating the second red spot of 

 A. silcts) ; anal spot black, crowned by two blood-red crescents and 

 an opaline blue intervening crescent ; above this anal spot are a 

 few scattered irregular black lines and dots ; an indistinct smoky- 

 grey line varied with black, from the median vein backwards, near 

 and parallel to outer margin ; tails as above : body below white. 

 Expanse of wings 41 millimetres. 



2 , Kikuyu, 6800 feet, Oct. 11, 1899. 



I have been through the descriptions and figures of the known 

 species, but can find nothing agreeing with the above. 



51. Epaaiera sidus. 



Iolaus sidus, Trimen, Trans. Ent. Soc. London (3) ii. p. 176 

 (1864) ; Hewitson, 111. Diurn. Lep. pi. 20. fig. 25 (1865). 

 $ (fragment), Eoromo, 7700 feet, March 22, 1900. 



" It is not an uncommon occurrence for me to be robbed of 

 intended victims to the cause of entomology by the many Fly- 

 catchers of as many species which inhabit the trees in our zariba. 

 In this instance, however, I robbed the Elycatcher of his prey : he 

 was pursuing the ' Blue ' heading downwards from a tree above, 

 snapping pieces out of her, when — as he was at the insect on the 

 ground — I drove him off and secured the ' Blue,' or rather her 

 mangled remains. Orange spherical ova." (R. C.) 



We want a series of this species badly, but the above is too 

 much damaged for the cabinet.
