lolaus MimoscB is remarkable for its dull-grey under- 

 side, and for the very little difference between the sexes. 

 HypolyccBTia Seamani, on the contrary, is almost as white 

 beneath as are most of the lolai, and the black and white 

 upperside of the female differs most strikingly from the 

 purple one of the male, Zeritis Orthrus has none of the 

 usual fulvous coloming on the upperside, and is the most 

 sombre-tinted member of its genus, with the exception of 

 Z. Leroma, Wallengren.

 Exp. (^) 1 in. 2f lin.; ($) 1 in. 3—41 Kn. 

 $. Glossy pale-blue, icith fuscous-grey borders. Fore- 

 wing : costa from base rather widely bordered with pale- 

 grey, diminishing to a point about middle ; extreme costal 

 margin very narrowly edged with ochreous ; apical border 

 very broad, commencing just at extremity of discoidal 

 cell, but somewhat abruptly narroAving on 2nd median 

 nervule, whence the hind-marginal border to anal angle is 

 not wide; sexual tuft on inner margin thin, dark-grey. 

 Hindicing: costal and apical margin narrowly, hind margin 

 very narrowly edged with friscous-grey ; two usual hind- 

 marginal spots black, that on anal-angular lobe superiorly 

 edged with greenish-silvery, and partly encircled with dull 

 white ; between the two spots, a third lunulate one, imme- 

 diately preceded by a whitish mark, which is itself preceded 

 by a faint fuscous one ; inner margin rather widely pale- 

 grey, hoary towards base; sexual badge near base con- 

 spicuous, consisting of a fuscous spot in a shining grey 

 ring. Underside. — Soft pale-grey ,tcith thin ferruginous- 

 ochreous stria; in both wings, a short stria closing discoidal 

 cell, and two long ones beyond middle, of which the inner 

 is continuous and well defined, the outer sub-lunulate and 

 rather faintly marked; between these two stricB some lohite 

 suffusion, in forexcing only towards inner margin, but in 

 hindwing from costa to inner margin. Hindwing: before 

 middle, a third stria, irregular and angulated, well defined, 

 extending from_ precostal to sub-median nervure; first 

 stria beyond middle very irregular, almost meeting the 

 outer one between 1st median nervule and sub-median
