Symphoristis ptychospila n.sp. 
$ $ q — io mm. Head white. Palpi and thorax white with a few dark 
fuscous specks. Abdomen light grey. Forewings elongate-lanceolate; pale 
grey more or less mixed with white and irregularly sprinkled with dark fuscous ; 
area of fold broadly and very irregularly suffused with white; an oval dark 
fuscous spot in this representing plical stigma, and one rather smaller and less 
distinct representing second discal: cilia white speckled with dark fuscous, 
towards tornus pale greyish. Hindwings grey; cilia pale greyish. 
Transvaal, Pretoria, in February and March (Swierstra) ; three specimens. 
Proterochyta n.g. 
Head with appressed hairs; ocelli posterior; tongue long. Antennae f, 
in d' ciliated, basal joint elongate, rather swollen, with strong pecten. Labial 
palpi moderate, slender, smooth, porrected, terminal joint as long as second, 
pointed. Maxillary palpi rudimentary. Posterior tibiae clothed with long 
fine hairs above. Forewings with 2 from f , 3 from angle, 4 absent, 7 and 8 
stalked, 7 to costa, 11 from middle. Hindwings nearly 1, lanceolate, cilia i|-; 
3 from angle, 4 absent, 5 rather approximated, 6 and 7 parallel. 
Type epicoena Meyr., erroneously referred hitherto to Elachista ; it is rather 
a puzzling form, but may perhaps be regarded as a primitive form of this 
family; the hindwings approach the Oecopborid type. 
HYPONOMEUTIDAE 
Prays citri Mill. 
Transvaal, Pretoria, in January (Swierstra); two specimens. A widely 
distributed pest of cultivated Citrus, not hitherto recorded from South Africa.

apex beneath. Antennae over 1, ochreous-whitish. Thorax whitish -ochreous,

metallic more or less edged laterally with coarse scattered dark fuscous 
scales, viz. small spots on costa at and near base, a quadrate spot in disc at 
its anterior angle connected with dorsum, an oblong spot in disc before 
middle and an elongate spot on dorsum beneath it, and rather large sub- 
quadrate spots in disc at f and f : cilia ochreous-yellowish. Hindwings whitish- 
ochreous; a small bronzy-ochreous spot on middle of costa, a spot crossing
