Melasina phaeocasis, n. sp. 
c S • 25-31 mm. Head, palpi light brownish-ochreous. Antennal 
pectinations 8. Thorax fuscous. Forewings moderately broad, 
rather dilated, termen rounded, rather oblique ; all veins separate ; 
greyish-ochreous strigulated dark fuscous irroration, small similar

dark fuscous suffusion beneath middle of disc and on end of cell:

Hindwings greyish ; cilia pale greyish-ochreous, a grey subbasal 
shade. 
Belgian Congo, Elisabethville, December, January ( C . Seyclel) ; 
8 ex. Allied to the preceding ; though distinguishable by the 
different tone of colouring, it seems possible that it might be a 
seasonal form, but it is probable that the larvae are subterranean, 
and that there is usually only one generation in the year.

Belgian Congo, Elisabethville, November, December { C . Seyclel) ; 
3 ex. (2 S , 1 ? ) (type Belg. Cong. Mus.). Nearly allied and very 
similar to hyacinthina Meyr., but that species has vein 9 of fore¬
