Mr. A. G. Butler on Madagascar Lepidoptera. 395 



on the posterior extremity of the third band of primaries 

 transferred to the costa of secondaries ; submarginal spots of 

 primaries considerably enlarged : secondaries with the inner 

 series of silvery spots on the outer border reduced to one or 

 two squamose lines, the submarginal spots five in number, and 

 the ocelloid anal spots consequently reduced to three in 

 number ; the anal area and border dull greenish instead of 

 orange. Expanse of wings 2 inches 6 lines. 



This species is referred to as an unknown form at p. 100 

 of the Catalogue of the Collection. 



Iolaus argentarius 3 , Butler. 



The male of this species is of a beautiful steel-blue colour 

 with azure reflections : primaries above with the costa brown, 

 the apical half brown with zigzag inner edge ; secondaries 

 with the costal border brown, the abdominal area rather 

 broadly pale greyish brown, two large, internally whitish- 

 edged and externally blue-edged black spots above the tails, 

 and two or three small linear spots connecting these with the 

 costal border. Wings below greyish brown, with white- 

 bordered black lines and spots arranged as in the female, and 

 with the same orange-bordered black spot and black -centred 

 emerald-green anal spot. Expanse of wings 1 inch 6 lines. 



The female which accompanies this male is not of the same 

 pure colour as the type on the under surface, the ground-colour 

 being distinctly grey, and the white borders of the black lines 

 almost as distinctly visible as in the male. 



Catopsilia rufosparsa, sp. n. 



? . Above like the Indian G. gnoma, but below of a dull 

 dark ochraceous colour, with the cross reticulations much more 

 numerous and orange instead of greenish grey, and mixed 

 with blood-red speckling ; the discal spots indistinct and con- 

 fused, only represented by subconfluent groups of reddish 

 scales as in C. florella ; silver spots smaller. Expanse of 

 wings 2 inches 6 lines. 



The type also differs from G. gnoma on the upper surface 

 in the confluence of the apical marginal red spots and the 

 absence of any trace of a discal series, in the absence of a 

 white vein across the discoidal black stigma, in the pink tint 

 of the secondaries, and the presence of a marginal series of 

 red spots upon the yellow border ; but all these characters 

 may vary, whereas the denser reticulation and confused spec- 

 kling of the under surface is characteristic of African and not 

 of Indian species. (See p. 33 of Catalogue of Hewitson's 

 Collection.)
