New or little-known African Butterflies. 5 
which the largest is between costal and subcostal nervures, a smaller 
one in discoidal cell, and the smallest on inner margin ; terminal 
disco-cellular marking elongate, curved, but little more than a third 
of the width of the corresponding marking in forewing ; eight spots 
in irregular discal series decreasing in size from costa to inner 
margin,—the 1st, 6th, and 8th before, and the 3rd and 4th beyond, 
the remaining three ; submarginal black streak situated as in fore- 
wing, but lunulate, and with much wider interruptions on nervules, 
—its 6th lunule faint orange-yellow, instead of black ; hindmarginal 
black spot just beyond this. orange-yellow lunule and smaller black 
spot at anal angle, thickly scaled with bluish-silvery ; a few black 
scales between the two spots ; hindmarginal black edging linear. 
Q. Pale-greyish, inclining to whitish on discs ; both wings, ex- 
cept along costal and hindmarginal borders, shot with pale-blue,— 
the former strongly, the latter slightly. Forewing : terminal disco- 
cellular marking very large and broad, as on underside, but not so 
sharply defined ; a submarginal ill-defined dusky stripe, succeeded 
by some very indistinct, sublunulate whitish marks. Hindwing: a 
submarginal ill-defined lunulate dusky stripe, immediately succeeded 
by a series of tolerably distinct whitish lunules, of which the three 
lower ones at their extremities unite with a white streak imme- 
diately preceding the black hindmarginal edging streak ; blue-scaled 
black spot between 1st and 2nd median nervules considerably larger 
than in ¢, and the preceding orange lunule better defined. Under-

A very worn female of this species in the British Museum, 
from Lake Nyanza, has been associated erroneously by 
Mr. A. G. Butler with the female of his Castalius hypoleucus 
(Proc. Zool. Soc. Lond., 1893, pp. 660—61), from Lake 
Nyassa.* The Nyanza female in question still retains part 
of the tail on the hindwing—an appendage wholly absent 
in L. perpulchra (hypoleuca). 
The nearest ally of Z. gigantea is L. lewcon, Mab., a 
native of Madagascar, which is, however, very much 
smaller, the male being barely 1 in. 3 lin. in expanse of 
wings, and on the upperside of a pure sky-blue, with 
paler discs, and a well-defined narrow black hindmarginal 
* As the Rev. Dr. Holland has pointed out (Proc. U.S. Nat. Mus., 
XVill, p. 239, 1895), C. hypoleucus is identical with his Lycxna per- 
pulchra described in the ‘ Entomologist’ for September, 1892, as well 
as with my own Lycena exclusa (Proc. Zool. Soc. Lond., 1894, p. 47, 
pl. vi, fig. 11, ¢).
