the disco-cellular spot, and in tlie liind-wings without the usual enclosed 
spot. This $ was accompanied by a ^ of large size, exhibiting the 
Jgripinna character above described (see note, p. 70). 
Dr. Felder, from whom I received a Bogos $ of JBoguensis, ex- 
pressed the opinion (op. cit., p. 174) that this form was very probably 
but a local variety of Severma. I have since, however, taken a ^ near 
Grahamstown and received a $ and two $ s from D'Urban, Natal. The 
marked feature of the costal bar of the fore-wings imparts to it some- 
thing of the aspect of Mescntina ; and it is noteworthy that in the ordi- 
nary $ 3 of Severina (especially on the under side), a fragmentary, or 
rarely complete, narroiv costal bar is present. 
It is very doubtful whether Severina is entitled to be held a distinct 
species from Creona, Cram. (ojJ. cit., i. t. xcv. If. c, d [J], e, f [$]). 
This Tropical- African form is, however, constantly smaller, and presents 
in both sexes proportionately wider borders (that of the hind-wings in 
the $ s having all the spots it contains on the upper side obsolete except 
the apical one), and on the under side unclouded neuration in the 
hind-wings, as well as broader and brighter longitudinal orange-yellow 
streaks. The $ has the disco-cellular spot of the fore-wing better 
developed, but the Vv^hite spots in the border much reduced ; the $ has 
a rather wide basal fuscous suffusion in both wings (much as in the $ 
Gidica, Godt.). 
The figures and description of Fieris Misa, Yollenhoven (Pollen 
and Van Dam's BechercJies sur la Faune de Madagascar, &c.. Part v. p. 
12, pi. 2, fF. 3, 1877), respectively so defective and insufficient, 
that I am unable with certainty to make out whether the Mayotte 
specimens represented and described are actually referable to Severina 
or not ; but I think that they most probably are so referable, the figure 
marked "3 ^ " being apparently a J of the slight variation above 
referred to as Agrippina, Felder, and that marked " 3 $ " to all 
appearance a J of the variety Boguensis, Feld.^ 
Colonel Bowker has sent me four pairs of this butterfly captured 
by him in copuld, viz., in 1873 a pair from Fort Warden, on the Kei 
River; in 1879 a pair, and in November 1881 two pairs from 
D'Urban, Natal. In the ^ s of the Kei River pair the clouded neura- 
tion of the under side of the hind-wings is marked only near base and 
hind-marginal border; in that of the D'Urban pair, 1879, it is almost 
obsolete ; and in those of the D'Urban pairs of I 88 i it is well developed 
except on the middle of the disc. The g of the Kei River pair is of 
average size, very yellow on the upper side, and has the central part of 
the under side of the hind-wings whitish streaked with yellow, — the 
dark neuration being very strongly marked ; that of the D'Urban pair 
of 1879 is small, whitish on the upper side, and with the neuration 
It is remarkable that, next to Creona, Cram., the nearest known ally of Severina is the 
Australian Teutonia, Fab., which is considerably larger, and with much broader upper-side 
borders in the S , and a costal bar (like that of Var. Boguensis) in the fore-wings of the $ ; 
while the neuration of the hind-wings on the under side is very strongly black-clouded.
