DESCRIPTIONS OF TRANSVAAL MICRO-LEPIDOPTERA.

II. 
A further instalment of interesting material is here described, partly 
as before, from the collection of Mr. A. J. T. Janse, partly from specimens 
in the Transvaal Museum collected by Mr. C. J. Swierstra. There is a 
marked generic relationship between this fauna and that of Southern 
Europe, whence it was probably mainly derived. 
Pterophoridae. 
Trichoptilus congrualis, Walk. 
Haenertsburg in December (Swierstra). 
Oxyptilus secutor , n. sp. 
Male, 19 mm. Head and thorax fuscous, apex of patagia whitish. 
Palpi two and a quarter, obliquely ascending, fuscous, basal joint whitish, 
second joint with two whorls of whitish- tipped scales, terminal joint whitish 
along posterior edge. Abdomen fuscous, mixed with whitish. Forewings 
cleft from middle, segments slender, first acute, second rather dilated 
posteriorly, with apex produced, termen very obliquely concave ; fuscous, 
in disk and towards base of dorsum partially suffused with light greyish- 
ochreous, along costa suffused with dark fuscous and sprinkled with whitish ; 
a blackish dot beneath costa near base, one in disk at one-third, surrounded, 
except above, with whitish suffusion, and one at lower angle of cleft ; a 
whitish spot on lower margin of first segment at base ; narrow whitish 
fasciae crossing both segments at one-third and two-thirds of length, 
apical area of both segments suffused with pale ochreous ; some black 
scales along lower part of termen of second segment ; cilia grey, on costa 
white barred with dark fuscous, elsewhere irregularly mixed with white 
and black scales, with white bars at tornus and apex of both segments. 
Hind wings dark grey ; cilia purplish-rosy-grey, on dorsum with scattered 
white and a few black scales, with a rather broad black scale-projection 
about three-quarters. 
Pretoria, in December (Janse) ; one specimen. 
Platyptilia molopias, Meyr. 
Haenertsburg and Woodbush Village, in December (Swierstra). In 
African specimens there are usually more scattered black scales on pos- 
terior half of dorsum of hind wings ; in Indian and Ceylon examples black 
scales in this position are scanty at best, whilst in African examples they 
are sometimes rather numerous ; on the anterior half of dorsum they are, 
of course, numerous in both forms. From the larger and more conspicuously 
marked direptalis the species may be distinguished by the different position 
of the dorsal scale-projection of hind wings, which in molopias is truly 
central (being also less triangular), i.e. placed so that its centre coincides 
with the centre of dorsum, whilst in direptalis it is post-median, being so 
placed that its anterior edge is in centre of dorsum.
