some remarkable Varieties of Sterrha sacraria. 457 
and they are remarkably constant, save that two females from 
South Africa pertain to the form known as sanguinaria. Zeller 
(“ Isis,” 1847, p. 491) gives the fullest information on this point; 
he indicates seven forms (including the type), chiefly differing in 
the presence or absence of a discal point, in the colour of the 
transverse fascia, and (slightly) in the ground-colour, 
The great amount of variation exhibited in these English bred 
examples opens up the question of the right that the so-called 
species of Sterrha, allied to S. sacraria, have to be considered as 
distinct. S. sanguinaria, Esper, has already been disposed of as 
a variety of sacraria. There then remain— 
(1.) 8. Labdaria, Cramer (Papil. Exot. pl. 181, p.), from Surinam ; 
now known only from the figure, which extremely resembles S. 
sacraria ; the only instance, supposing the locality to be correct, of 
a Slerrha occurring on the American continent. 
(2.) S. anthophilaria, Hiibner, from South Russia; with the 
. anterior wings of the typical sacraria, and with the posterior 
wings blackish, with a central pale band. 
(3.) S. rosearia, Treitschke (Schmett. von Europa, vol. vi. pt. 2, 
p- 298), from the Ionian Islands and South Russia, figured by 
Duponchel (pl. 178, fig. 8), and by Herrich-Schaffer (antho- 
philaria, fig. 29); differing from the typical sacraria slightly in the 
form of the wings, with the colour of the anterior entirely rosy- 
grey, and with the posterior wings of anthophilaria (much re- 
sembling the hereinbefore described No. 1); given by Evers- 
mann as a variety of sacraria, and by Staudinger (‘Catalog 
Lepidopteren Europas,” p. 76) as perhaps a variety of the female 
of anthophilaria. : 
(4.) S. plectraria, Guenée (Phalénites, t. ti. p. 176, pl. viii. fig. 7), 
from Abyssinia; differing from sacraria by its larger size, more 
triangular wings, and different coloration, 
(5.) S. participata, Walker (Brit. Mus. Cat. Lep. pt. xxi. p. 
1060, 7), from Namaqua Land; with reddish anterior wings, and 
a dark purplish-red broad oblique band, white discal spot, and 
pinkish-purple apical cilia. 
(6.) S. peculiata, Walker (loc. cit. 8), from Natal; with red- 
dish-ochreous anterior wings, and a pale discal spot. 
S. florilegaria, Zeller, Guenée, from Caffraria, I put out of the 
question, because Guenée states that, despite its resemblance to 8, 
sacraria, he is uncertain if it really pertains to the genus. 
After examining the six English specimens, bred from the same 
brood of eggs, I can come to no other conclusion than that all
