78 RHOPALOCERA AFRICA AUSTRALIS. 



ence in its width, and joining the very broad apical and hind- 

 marginal band rather abruptly. Hind-wing : powdered with 

 black at base ; black band on hind-margin nearly as broad as 

 that of fore-wing (very much broader then in T. Rahel), 

 diminishing to a point at anal angle. UNDER-SIDE. "Yellow ; 

 with a marginal series of little black dots. Fore-wing : three 

 very small black dots in the discoidal cell; three or four brown 

 dots along costa. Hind-wing : very finely powdered with 

 blackish ; two or three waved striae of blackish-grey more or 

 less clearly defined." 



? . " Sulphur -yellow ; powdered with blackish, especially 

 near base. Fore-wing : the marginal band not continued 

 along costa. Hind-wing : the marginal band often scarcely 

 indicated." Boisd. F. E. de Mad., $c. 9 pp. 20, 21. 



I think that three specimens of a Terias in the collection of the South 

 African Museum may be considered as females of this species.* They 

 expand from 1 in. 4 lin 1 in. 6 lin. M. Boisduval's description of 

 the $ is so very brief that it is impossible to speak positively on the subject. 

 In the specimens referred to, the band on fore-wing is dull-blackish, and 

 commences on costa before the middle ; it is interrupted on hind-margin just 

 above anal angle, but there is a blackish mark at anal angle. The band on 

 hind-wing, though present in all three specimens, and rather broad, only 

 extends as far as extremity of second median nervule its inner edge is 

 irregularly dentate. The under-side is closely and finely irrorated with 

 blackish, particularly the hind-wing, whicb presents the waved blackish 

 bands mentioned in the description of the $ by M. Boisduval. When 

 engaged in making descriptions of the South African Rhopalocera in the 

 British Museum, I did not notice this species as one found within the limits 

 of the region South of the Tropic. Mr. E. Doubleday, however, in the 

 Appendix to his List of Lepidoptera in the British Museum notes a specimen 

 of Pulchella from Port Natal; and Drege, in his "Price List " of South 

 African Insects, mentions Xanthidia pulchella as one of those he had col- 

 lected. The description of the upper-side of the $ , given above, is from 

 the figure in plate 2 of the "Faune de Madagascar, &c.," Boisduval's 

 description being too general to be of any service without the figure. I 

 think it probable that T. Pulchella will prove to be a variety of T. Rahel.

* An examination of Mr. D'Urban's specimens has since shown me that 

 these three ? examples are T. Rahel, not T. pulchella.
