'2 MK. A. G. BUTLER ON LEPIDOPTERA [Jan. 17, 



clearer iu colour and the markings are almost wholly obliterated. 

 The figures in M. Grandidier's work are taken from rather small 

 exam))les ; but this form of Terias is very variable in size, our 

 smallest male example expands 28 millim, and our largest 55 millim. 



Var. ? The external border of primaries wider and more quadrate 

 at apex, narrower or obliterated at external angle. Expanse of 

 wings, S and 2 37 millim. 



d'. Stazione Bauri, September 1883; ?. Lado, 20th August,

Now that the text of Monsieur Grandidier's work has appeared 

 I much regret to find that the serious errors, which I pointed out 

 ill my paper on Lepidoptera from Somali-land (P. Z. S. 1885, 

 pp. 762, 767, 768, 769), have not only not been corrected, but, on 

 the contrary, have been insisted on. Now, whilst no great blame 

 attaches to a Lepidopterist who accepts the statement of liis collector 

 as to the capture of a series of Arabian species in Madagascar, he 

 injures his reputation when he persists in associating as male and 

 female the males of different species, as M. Mabille has done in the 

 case of the males of Charaxes antamboulou and C. cowani ; that both 

 are males, the fidelity of the illustrations shows at a glance, apart 

 from the fact that the sexes of both are in the Museum collection : 

 the coloration and pattern of the under surface in these two species 

 differs more than in the sexes of any Charaxes known to me ; in the 

 true sexes there is no such difference.

Originally described from the Victoria Nyanza and subsequently 

 received from Kilima-njaro ; the examples from the latter locality 

 have the veins of the wings blacker and the black bands across the 

 wings slightly broader than in the type. 



91. Teracolus PROTOMEDiA.

 Occurs in Upper Egypt, Nubia, Aden, and Somah-land. 



92. Teracolus puniceus, sp. n. 



J . Allied to T. /letcera, but smaller, the magenta-coloured apical 

 patch triangular, terminating at the third median branch ; the 

 blackish border narrower ; a minute black dot at end of cell ; the 

 secondaries immaculate : under surface of primaries white with 

 cream-coloured apical patch, of secondaries cream-coloured, crossed 

 beyond the middle from costal to third median branch by an oblique 

 interrupted narrow brown line, beyond which there is a single spot 

 on second median interspace. Expanse of wings 64 millim.
