1/2 MR. A. G. BUTLER ON THE GENUS DANAIS. [Mar. 27, 



My species D. ismareola turns out to be the female of D. ismare 

 (Cramer). I rather hesitated to describe this species as new, on 

 account of its similarity in pattern and coloration to D. ismare ; but 

 the great differences in form and expanse of wing, and also in neu- 

 ration, combined with the fact that our specimens were from different 

 localities, decided me. I have now, however, seen a most interest- 

 ing hermaphrodite (see fig. 1, p. 1/3), having the wings of ismare 

 on one side, and of ismareola on the other, but with the male sexual 

 spot on both of the hind wings ; in the hind wing of the female 

 there is a curious malformation of the nervures, two of them ori- 

 ginating from a single foot-stalk ; the two sides of this insect vary in 

 size as follows :— Front wings, costa 1-| and \\^ inch ; hind wings, 

 length 1^ and If inch.

Allied to D. inuncta (Butler), from which it differs in being yel- 

 low instead of white ; the wings of a slightly different form, the inner 

 edge of hind margin forming long hastate projections between the 

 nervures ; front wings with cell entirely brown, and apical submar- 

 ginal spots very small. 



5. Danais lutescens, sp. n. (Fig. 3, p. 1/3.) 



Alee supra alba viridescentes, fascia subapicali magna nee in ma- 

 culas distincta, anticce, breves, posticce rotundatce : aliter ut in 

 D. cleona {Cramer). 6 ■ Alar. exp. unc. 3. $ . Alar. exp.

This species is closely allied to D. cleona of Cramer, from which 

 it differs chiefly in its pale colouring, more rounded and shorter wings, 

 and larger spots.
