from tlie Stockholm Museum by Mr. Chr. Aurivillius, agrees with Wal- 
lengren' s description {loc. cit.), and with a $ from Delagoa Bay and 
another from Transvaal, in wanting altogether the white inter-nervular 
streaks usually marking the confluent discal ray and hind-marginal 
border of the hind-wings, so that a very broad uniform black border 
covers the lower two-thirds of the outer part of those wings. Mr. 
J. L. Fry has sent me a $ similarly marked from Tati. 
I am unable to distinguish Boisduval's Uio7ie from his FIdegetonia, 
the only characters noted in his descriptions being the smaller size and 
greyish-yellowish under side of the former, — features highly variable, 
and presenting every gradation. 
Mr. Butler (loc. cit., pp. 143—144) identifies Plilegetonia, Boisd., with 
Antigone, Boisd. {Sp. Gen., p. 572), but the description of the latter 
(only the $ is described) as having on the upper side " la hase et la 
commissure legerement saupoudrees de gris," and as regards the hind- 
wings, simply " une hordure noire crencUe'' indicates a different insect 
from the heavily black banded and bordered Phlegetonia ; although it 
must be admitted (as stated under T. Antigone) that the darkest 
examples do nearly approach Phlegetoiiia in marking. 
This is one of the most striking of the smaller species of Teracolus, the 
relatively large size of the orange patch and the depth and extent of the black 
markings rendering it very conspicuous. I found it very seldom during my 
stay in Natal, but abundantly in the scrub bush at Uitenhage, Cape Colony. 
It is an active insect, but not swift, and flies close to the ground, appearing in 
the height of summer (January to March). Near Grahamstown I also met with 
the species, and on the 12th February 1870 captured the united sexes. In 
this pair neither sex had the black markings at their highest development, and 
the well-marked apical orange of the $ partly penetrated the upper part of its 
broad inner blackish border. In another pair, taken in copula by Colonel 
Bowker near the Upper Tugela on 2d April 1880, the $ has heavy dark mark- 
ings, but the $ is scarcely more heavily marked than the darkest 9 s of Antigone, 
and has the apical orange superiorly almost as in the $ , the usual dark inner 
border being reduced to a series of dusky nervular marks well within the orange. ^

^ A very fine 9 , sent from Weeaen County in Natal by Mr. J. M. Hutchinson, consider- 
ably surpasses that here noticed as regards the width of the apical orange and the faintness 
of the traces of the inner dark border of the orange, but presents, on the contrary, all the 
great black markings in their highest development on both wings.
