the black hastate markings across the disk thickened and 
elongated ; enclosed in diffused pale bluish oblong spots on 
the secondaries in place of the lilac and white belt of 7. munda ; 
these spots also do not extend inwards to the discal series of 
black lunules which bound the discal belt of 7. munda: on 
the under surface the black markings are arranged much as 
in 7’. munda, but the external area is suffused with lilacine, 
and the divisions of this area towards apex of primaries are 
largely pearly whitish, those of secondaries less so.

&. Nearly allied to 7. apsarasa; the white markings on 
the primaries more irrorated with brown; the blackish 
sagittate markings on all the wings shorter; the whole inner 
border of the discal belt of secondaries above the lunated line 
pearl-white: under surface more yellow in tint than in 7’. apsa- 
rasa, the basal area of primaries suffused with tawny; the 
spots enclosed by the double series of lunate markings pearly 
white on all the wings, as also are the diffused spots behind 
the sagittate markings.

The female is much more varied with white than that of

Tanaecia albifasciata, sp. n. 
g. Allied to 7. martigena; the primaries above with the 
inner bordering of the hastate markings almost wholly suffused 
with brown; the discal belt of secondaries not traversed by 
a grey-blue lunate line; the hastate black markings on the 
secondaries bounded externally by larger white or lilacine 
spots. On the under surface the differences are far more 
marked :—The basal area is more tawny, the markings upon 
it mostly ferruginous brown instead of black; the discal belt 
is continuous and pearly white, not interrupted by angular or 
lunate markings; the submarginal markings are more open 
(sagittate rather than hastate) and form the inner edges of a 
series of large pearl-white spots.

It is possible that this may prove to be only a form of 
T. Frihstorferi, but in outline of wing it is more like
