wings lanceolate ; ochreous-white ; plical and second discal stigmata 
small, black, plical at about middle of wing, first discal represented in female 
by a single black scale obliquely before plical and near costa ; cilia ochreous- 
white. Hind wings and cilia ocbreous-white, cilia in male yellowish tinged 
towards base. 
Beynspoort (near Pretoria) and Pretoria, in December and January 
(Janse) ; two specimens. Very near the European triatomea, but dis- 
tinguished by ochreous- white hind wings. 
Mendesia aganopa, n. sp. 
Male, 11 mm. Head, palpi, antennae, and thorax white. Abdomen 
ochreous- whitish. Fore wings rather broad-lanceolate, pointed ; white ; 
cilia white. Hind wings and cilia ochreous-whitish ; no additional branch 
of vein seven. 
Rietfontein No. 57 (N.E. Pretoria District), in February (Janse) ; one 
specimen . 
Gracilariadae. 
Lithocolletis encaeria , n. sp. 
Male, 6 mm. Head and thorax bronzy-ochreous, face white. Antennae 
and abdomen grey. Fore wings lanceolate ; golden-bronzy-ochreous, 
posteriorly slightly sprinkled with blackish points ; a very short slender white 
median streak from base ; a very slightly indicated slender whitish somewhat 
angulated fascia at one-quarter ; a slender white fascia at one-half, angulated 
above middle, margined anteriorly with a few black scales ; a white spot on 
costa at three-quarters, and one on dorsum opposite, irregularly margined 
with black scales, between these is a group of black scales in disc; a 
triangular white spot on costa hardly before apex, beneath which are some 
black scales along termen ; cilia pale ochreous, beyond a blackish median 
line ochreous-whitish. Hind wings grey; cilia pale grey. 
Pretoria, in October (Janse) ; two specimens. 
Epicephala pyrrhogastra, Meyr. 
From examination of further specimens the ochreous-reddish colour 
of abdomen appears to be that of the chitinous substance, the scales being 
grey and white as described ; the same peculiar reddish colour is apparent 
in other parts of the body and head if denuded. 
Epicephala barbitias, Meyr. 
A second female and what is probably male of same species, 
sent by Mr. Janse, taken at Pretoria in February and March ; 
female quite like type-example ; abdomen (broken in type) 
whitish-grey ; male differs in having dorsal white streak less 
marked, tending to break up into oblique streaks, with small blackish 
spots above it before and beyond middle, markings towards apex 
forming four pairs of fine oblique light fuscous strigulae from costa and 
termen meeting at acute angle and somewhat marked with whitish, 
separated with dark fuscous, apical black dot limited anteriorly by a 
hardly curved white line (instead of having a V-shaped line within it) 
abdomen with large whitish-ochreous claspers and anal tuft ; this might 
possibly be a distinct species, but in other respects the similarity is such 
as to suggest that the specimens are sexes of the same species.
