practically enclosed. Madagascar forms seem no more 

 constant than those from other localities. Of two % $ 

 before me one is like Mabille's figure (pi. 11, /. c), and the 

 other is similarly marked, but the f-w. is flushed with 

 yellow, and the h.-w. is ochreous. 



Thurau's ab. connexa has the cell spots of the h.-w. 

 beneath contiguous with those on the discocellulars. The 

 same author's ab. excentrica has the spots in 3 and 6 of 

 h.-w. drawn out to meet the black arches of the mar2;inal 

 border, whilst those in 4 and 5 are partially extended in 

 the same manner, 



Oberthiir's ab, melas is a melanic aberration of the ^. 

 Grose-Smith's suhserena is not separable from the present 

 species. It is a ^ in which the h,-w, spots are scarcely 

 visible above, and represented beneath by one spot in 7, Ic, 

 lb, and la, and a basal spot in cell. On the upperside the 

 hind margins of both wings are densely black with a few 

 pale spots on h.-w. margin, and the f,-w, discal black bar 

 is represented only by a spot at end of cell separated from 

 the costa by the ground-colour. 



Strand's intermediana is a curious form, the type of 

 which has large marginal spots on the black borders of 

 both wings. The subapical black bar is interrupted. The 

 spots of h.-w. underside are as in typical terpsichoir, but 

 between them is a considerable amount of red scaling. 

 There is also a curious dusting of brown scales on the 

 nervures in the middle of the wing. With the type in the 

 Berlin Museum are three co-types. These show very little 

 of the brown scaling and much less of the red. 



The form ventura has hitherto been regarded as a dis- 

 tinct species, and the remarkable difference in the pattern 

 of extreme examples would, in the absence of intermediate 

 forms, amply justify such a conclusion. The form may be 

 thus described : — 



A. terpsichore f. ventura. 



^. Expanse 42-58 mm. Wings deep orange tawny. F.-w. 

 brownish black along costa. Apex black 4-5 mm. wide and 

 a black hind-marginal band 2-3 mm. wide bearing elongated 

 internervular spots of the ground-colour. This marginal border 

 is widened at nervules 3 and 4 where it joins a transverse black 

 bar proceeding from costa just beyond end of cell, thus enclosing 

 a more or less ovate subapical patch of the ground-colour. This 

 patch is not always completely enclosed. A very slight blackish
