326 RHOPALOCERAAFRICJE ATJSTRALIS. 



This Asiatic Genus seems strictly intermediate between 

 Anthocaris and Eronia ; it follows Idmais (vide p. 62) in the 

 classification I have adopted. The few species known are 

 from India and the Eastern Archipelago. I include the 

 Genus as South African on the authority of "Wallengren, 

 who records a new species, closely allied to the well-known 

 T. Marianne, Cram., taken by Wahlberg.

White, very widely glancous at bases ; a reddish-fulvous, 

 black-bordered patch in fore-wing at apex. Fore-wing : 

 glancous at base so wide that the white ground only appears 

 as a fascia ; costa and hind-margin very narrowly black- 

 edged ; fulvous patch triangular, occupying whole of apical 

 region, separated from white by a broad straight, black 

 fascia, and divided by nervules into eight elongate, out- 

 wardly slightly-rounded spots ; black fascia extending from 

 costa to hind-margin above sub-median nervure, and thence 

 to inner-margin, so that anal angle is broadly black. 

 Hind-wing : a broad black hind-marginal border, inwardly 

 dentate on nervules. UNDER-SIDE. White: a rounded 

 disco-cellular blackish-fulvous spot in fore-wing, a lunate 

 fulvous-centred one in hind-wing ; a common transverse, 

 discal row of fuscous or fuscous-ferruginous spots (not 

 ocellate), in fore-wing angulated on second discoidal nervule 

 and traversing apical fulvous (which is less than above and 

 ill-defined) ; extremities of nervules black. Fore-wing : 

 apex widely white, very faintly tinged with yellowish ; 

 basal glancous outwardly edged by an angulated fuscous 

 fascia ; ends of three nervules next anal angle marked with 

 rather large black spots. Hind-wing : basal glaucous fades 

 gradually into ground-colour ; costa at base yellow. 



Translated from the description of Wallengren, who distinguishes the 

 species from Marianne, Cram., by the straight inner-border of the apical 

 patch, the narrowness of the costal and hind-marginal border, and the 

 pale hue and markings of the under-side.
