Only three species have been recorded from South Africa so far, which may 
be distinguished as follows : 
1 a. Fore wing with a rust-brown fascia below lower median reaching till 
near termen below vein 6; areole long and narrow, vein 6 from 
areole at base ....... rubrifascia 
b. No rust-brown fascia in fore wing, areole short or absent ... 2 
2 a. Areole absent; 7, 8, 9, 10 stalked; fore wing yellowish-brown; hind 
wing irrorated with fuscous ..... rubritincta 
b. Areole short; 10 from beyond areole; fore wing ochreous-white ; hind 
wing white with some brown irroration in and just beyond the 
cell flavida 
Pydna Rubrifascia. 
(PI. XI, fig. 3.) 
Pydna rubrifascia Hmpsn. A.M.N.H. 8. v. p. 486 (1910). 
The branches of the antennae of this, species are longer than in rubritincta, 
nearly four times. 
I have seen one $ specimen in the collection of the South African Museum, 
collected at Salisbury by Dr M. Melle. 
Pydna Rubritincta. 
(PI. XI, figs. 2, 4-8.) 
Pydna rubritincta Hmpsn. A.M.N.H. 8. v. p. 485 (1910). 
Of this species I have seen a specimen in Mr Clark’s collection, which is a 
duplicate of the specimen sent to Sir George Hampson and identified by him as 
such. This specimen and my own agree very well with the description except 
that the postmedian spots go beyond vein 6, right up to the costa; my speci- 
mens are only 41 mm., not 44 mm. They come from Zululand (Eshowe, 
Nkwaleni) ; Natal (Sarnia) and Transvaal (Barberton) ; all collected by myself 
in Dec. and Jan. 
The markings of the $ are like those of the the sexes only differ in 
the antennae. 
Spec. auct. : Pydna flavida Hmpsn. A.M.N.H. 8. v. p. 485 (1910). 
I have not seen specimens of this species, which is recorded from Durban 
and Charlestown (Natal). 
Genus POLELASSOTHYS nov. 
(PI. XII, figs. 2-8.) 
Type plumitarsus. 
$. Proboscis very much reduced, almost absent; palpi porrect, short, 
hardly reaching frons, consisting of two joints only; first joint short, covered 
with rather long scales and hairs at sides and at front; second joint of about the 
same length, joined with a neck-like part to the first joint, sub-globular, 
ending in a sharp point and covered with long scales, mixed with hairs; eyes 
naked, large, round; frons fiat, covered with scales and hairs; antennae of 
short, less than half of costa, basal f rd curved downwards, apical third upwards ; 
bipectinated from fth, pecten about 6 times shaft; first joint of shaft with a tuft 
of hairs and scales in front; in $ the shaft is still shorter, pectinations till frd 
and about four times shaft; thorax covered with scales mainly, forming a
