LEHDOPTERA OF KARACHI AND ITS NEIGHBOURHOOD. 277 



I. ochreipennis, Butler, below both sexes with the three spots in 

 the fore wings as in /. vestalis; hind wings in both sexes flesh colour* 



t. peehts, Swinhoe, is like a yellow I. vestalis. 



I. dubia, Swinhoe, is like a very large I. vestalis, with all the black 

 markings much deeper above aud below, with a discal series of large 

 reddish brown spots in the hind wings below. 



I. protractus is marked like I. puelaris above and below, but is of 

 a deep salmon colour above. There are several other differences 

 between the various species, but by these alone they can be easily 

 separated, and these characteristics appear to be quite constant. 



52. Idmais dynamene. 



Pontia dynamene, Klug., Symb. Phys. pi. 6, f. 15, 16 (1829); 

 Teracolus carinfer, Butler, P. Z. S., 1876, p. 138, pi. 7, 8, 

 89. 

 Very common all the year round. 



53. Idmais Calais. 



Papilio calais, Cramer. Pap. Exot. i., pi. 53, f. C. D. (1 779), 

 One taken by Captain Becher at Karachi in June 1885, and is 

 identical with my Aden specimens identified by Mr. Butler. 



54. Callosune dulcis. 



Teracolus dulcis, Butler, P. Z. S., 1876, p. 157, pi. 7, f. 13 ; 



Teracolus dims, Butler, 1. c. f. 11 ; Teracolus eboreoides, 



Butler, 1. c. p. 1858, pi. 7, f. 12 : Teracolus immaculatus t 



Swinh., P. Z. S., 1884, p. 443. 



Common from April to August. 



Typical specimens of all the above can easily be separated, but 

 there are so many intermediates, it is impossible to separate thew 

 as distinct species. G. dulcis is the common form, the hind wings 

 below have a complete whorl of small discal brownish spots, and C. 

 immaculatus, C. eboreoides, and G. dims are larger butterflies. Below 

 on the fore wings are two black patches on the outer margin near the 

 hinder angle. In C. eboreoides, the discal spots on the hind wings are 

 double, prominent, complete, and very black; in G. dims these large 

 spots are only represented by two or thi'ee pairs from the costa 

 downwards, and in O. immaculatus they are entirely absent, there 

 being many only one pair of spots on the costa. 



55. Collosune subroseus. 



Teracolus subroseus, Swinhoe, P. Z, S,, 1884, p. 443, pi. 40, 

 f. 67. 

 July to November.
