There are evidently large and small forms of this species, as in the 

 allied T. plnllipsii from Somali-land : hitherto we have received male 

 examples equal in size to that figured by Klug ; the male now received 

 is much smaller and has lost the marginal spots on secondaries ; on 

 the other hand, the female figured by Klug is small and evidently 

 belongs to our small male, whilst the female just received is large 

 and heavily marked and belongs to Klug's male. It is probable 

 that the small type is the winter form of the species; but, after all, 

 conjectures are valueless in these questions.

102. Glutophrissa contracta, sp. n. 



Intermediate in some respects between G. saba of West Africa 

 and G. malatha of Madagascar. The male differs from both species 

 in the slightly narrower black border to the primaries above, the 

 creamy colour of the apical area and secondaries, and total absence 

 of all black spots on the under surface; the female differs from 

 both in having the white belt of primaries above contracted to a 

 narrow oblique spot at the end of the cell, though from the median 

 vein to the inner margin it remains as wide as usual ; on the under 

 surface the yellow colour at the base is duller and more saffron- 

 tinted ; the apex is as white as in the Madagascar form. Expanse 

 of wings, 6 56-58 millim., ? 49-58 millim.

Nine examples were obtained ; the male most nearly resembles 

 M. Mabille's figure of G. epaphia ,5 , a form which I have never 

 seen from Madagascar. The true G. epaphia is the Pieris matuta 

 of Doubleday and is the male of G. saba. The male of G. malatha 

 (the Madagascar form) has similar black spots below, but is yellower 

 in tint ; it does not agree with M. Mabille's narrow-bordered males,

 The female is a singularly beautiful example, the whole of the 

 ground-colour being of a bright sulphur-yellow.
