Pierine Butterflies oj the Genus Delias. 163 



secondaries ; in some examples from Burma it almost fills 

 the area included between the first and second median 

 branches, leaving only four diffused spots between it and the 

 costa; in others it is limited by the first median branch, 

 leaving five diffused spots j but all kinds of links between the 

 two types also occur. 



79. Delias parthenope. 



Thyca parthenope, Wallace, Trans. Ent. Soc. ser. 3, vol. iv. p. 347 



(1867). 

 Thyca ninus, Wallace, 1. c. pi. vii. fig. 1. 



Elephant Island, Malacca, Borneo. B. M. Sumatra 

 (G. & S. coll.). 



The type from Malacca is in the Hewitson collection mixed 

 with the preceding species. 



80. Delias pandecta. 

 Delias pandecta, Staudinger, Iris, 1889, p. 23. 



Two males and one female, Palawan. Four examples 

 (Godman and Salvin coll.). 



We have a female from Nias which resembles this species 

 in colouring, but differs above in having the greyish- white 

 macular belt on the upper surface of the primaries across the 

 end of the cell, so that it touches the white spot. This may 

 possibly be nearer to D. aglaia, but without the male it is 

 impossible to decide.
