 wings, bordered with black on both sides ; the hind-wings 

 probably with a marginal row of black spots.

Under these names are included a number of African, 

 Arabian, and Indian Butterflies, which present no very salient 

 characters to distinguish them from Callosune^ except their 

 general colour and markings. Instead of " Orange Tips," we 

 have here moderate sized or rather small Butterflies, with more 

 delicate and rounded wings than in Eurymus, and of a paler 

 orange or yellow colour, generally with much slighter dark 

 borders. Several of Mr. Trimen's sections of Teracolus will 

 fall under this genus, which is used to include various dis- 

 cordant groups of species, differing almost as much from each 

 other as they do from Callosune. Those which most nearly 

 approach the latter genus are Pontia en's, Klug, and its allies. 

 This is a white species found in Africa and Arabia, with broad 

 black bands covering the junction of the wings, and coalescing 

 with the lower end of the black sub-marginal band, which is 

 spotted with pinkish-white towards the tips ; the female is 

 yellower, and the dark markings are much less extended. 



The type of Colotis is C. amata (Fabricius), a common Indian 

 Butterfly, measuring about an inch and a half across the wings. 

 This Butterfly is not unlike a small Eurymus above, being of 

 a. brick-red colour in the male, and yellow in the female, with
