The differences are partly sexual and varietal, but partly also the effect of an 
interesting dimorphism between the carmine and yellow colouring which is 
worthy of study and perhaps due to slight chemical action, the forms being 
taken together in equally fresh condition. It ought not to be difficult to find 
the larva and breed the species freely. Information is also required as to how 
the imago holds its hind legs in repose. 
GLYPHIPTERYGIDAE 
Brent hia leucatoma n.sp. 
$ 7 mm. Head and thorax bronzy-fuscous. Palpi whitish-fuscous, second 
and terminal joints each with two darker rings. Abdomen dark fuscous. 
Forewings moderate, posteriorly dilated, costa slightly arched, apex rounded-

scales whitish, forming a very fine transverse striation ; an irregular angulated 
whitish transverse line about J ; indistinct whitish dots on costa beyond middle 
and at f , on dorsum at § and before tornus, and in disc at f ; a faint transverse- 
oval whitish ring in disc at §; a minute silvery dot near costa towards apex; 
a slender black marginal streak, marked with two round white dots; a group 
of five or six golden-metallic dots arranged in a double series on lower half of 
termen, surrounded with dark fuscous : cilia yellow-whitish, towards tornus 
fuscous (imperfect). Hindwings dark fuscous, bases of scales pale; an oblique- 
oval whitish ring in middle of disc ; a transverse whitish mark towards termen 
in middle, and a short whitish line from tornus; a violet-metallic mark from 
costa near apex; an almost marginal violet-metallic line near termen from 
apex to below middle; cilia fuscous, with oblique whitish patches above and 
below middle of termen (imperfect). 
Natal, Durban, in August (Janse); one specimen. 
Glyphipteryx decachrysa n.sp.

anterior half infuscated ; a white somewhat oblique bar from dorsum before ^ , 
reaching fold ; five costal and two dorsal coppery-golden-metallic slender 
slightly oblique streaks rising from white marginal dots, first costal just before 
middle, reaching ^ across wing, next two longer, last two shorter, dorsal 
reaching half across wing, first at f ; a short coppery-golden-metallic streak 
along tornus, a small discal spot above this (both these partly edged with 
black) , and a short mark on termen beneath a small black apical spot : cilia 
whitish, suffused with bronze within a dark bronzy-fuscous postmedian shade, 
ndented%with white above middle of termen, on tornus with a dark fuscous 
patch. Hindwings elongate-trapezoidal, blackish-grey; cilia dark grey.
