point somewhat widely separated from the outer margin by a white line. A trans- 

 verse oblique band of black, poorly defined, runs from the extremity of vein 2, toward 

 the end of the cell, and serves to delimit the orange-red apical patch from the white 

 inner area of the wing along the lower half of its inner margin. There is a short, 

 pale orange, transverse bar at the end of the cell. The secondaries have tlie ends of 

 the nervules lightly tipped with black. 



On the underside the primaries are white, with the orange-red of the apical patch 

 faintly showing through from the upperside. There is a minute black spot at the 

 end of the cell. The costa and the apical area are laved with pale yellow, and pro- 

 iiisely irrorated with pale-brown spots and strigse. 



The secondaries on the underside are pale yellow, profusely covered throughout 

 with pale brown spots and strigse like those on the primaries. The body is blackish 

 above and pale yellow below. The antennte are black (Holland, Lc). 



Female. — Like the male, but the black sub-apical transverse line delimiting the 

 orange-red apical patch on its inner side is, in this sex, continued across the wing to 

 the costa, instead of terminating, as in the male, before reaching the end of the cell, 

 and there is a black spot at the end of the cell on l)oth primaries and the secondaries. 



Expanse 28-38 mm. (Holland, I.e.). 



Habitat. — Aldabra Island, Indian Ocean. 



This species is evidently closely allied to T. ephyia, from Nubia, and it is interesting 

 to find such a form apparently restricted to an island in the Indian Ocean. 



T follow Dr. Butler in keeping it distinct, but I must say that I cannot see any 

 characters which justify the separation of T. evnnflikles from 7'. cp/ii/ia. This is 

 probably because I have never seen an actual specimen, the Aldabra species being 

 unrepresented in any museum in this country. Doubtless on comparison with its 

 Nubian ally specific differences would be easily discovered, as it is difficult to 

 believe that an Aldabra butterfiy could be specifically identical witli a Nubian species. 

 For the opportunity of figuring 2\ cvanfliides in the present work, I am indebted to 

 Dr. Harrison (r. Dyar, of the U. S. National Mu,seum, who most kindlj^ sent me 

 coloured drawings of the types, and I tiumk him most heartily for this evidence of 

 international courtesy, without which my work would have been rendered imperfect. 



Dr. Butler's o))inion is as follows: 'Allied to C. evaiif/ie, but evidently distinct. 

 It has the brown irroration and striation of the under surface characteristic of the 

 dry-season T. evaufhe of Madagascar, Init upon a pale yellow ground tint, whereas in 

 T. cvaiit/ie the ground-colouring of the under surface is dead white."
