the disco-cellular spot, and iu the hind-wings without the usual enclosed 

 spot. This $ was accompanied by a ^ of largo size, exhibiting the 

 Jgrippina character above described (see note, p. 70). 



Dr. Felder, from whom I received a Bogos $ of Bocjucnsis, ex- 

 pressed the opinion (op. cit., p. 174) that this form was very probably 

 but a local variety of Sevcrina. 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 Mesentina ; and it is noteworthy that in the ordi- 

 nary $ s of Severina (especially on the under side), a fragmentary, or 

 rarely complete, narrow costal bar is present. 



It is very doubtful whether Severina is entitled to be held a distinct 

 species from Creona, Cram. (oj). cit., i. t. xcv. ff. c, o [$], e, f [g]). 

 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 Avhite 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 Picris Elisa, Yollenhoven (Pollen 

 and Van Dam's Becherches sur la Faune de Madagascar, &c.. Part v. p. 

 12, pi. 2, fF. 3, 1877), are respectively so defective and insufiicient, 

 that I am unable with certainty to make out whether the iMayotte 

 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 ^ of the slight variation above 

 referred to as Agrippina, Felder, and that marked " 3 ? " to all 

 appearance a ^ of the variety Bogucnsis, Feld.^ 



Colonel Bowker has sent me four pairs of this butterfly captured 

 by him in copidd, viz., in 1873 a pair from Fort Warden, on the Kei 

 Eiver ; 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 1881 it is well developed 

 except on the middle of the disc. The $ 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 



1 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. Bofjuensis) in the fore-wings of the ? ; 

 while the neuration of the hind-wings on the under side is very strongly black-clouded.
