CALLOSUNE.

In Callosune^ the wings are broader and shorter than in 

 Euchloe^ the hind-wings are frequently bordered or spotted with 

 black on the hind-margin above, but are not tesselated with 

 green beneath, being generally uniformly coloured, with but 

 little pattern. They are white or yellow, sometimes merely 

 with an orange apical spot on the fore- wings, narrowly bordered 

 outside with black, but more frequently, the apical region is 

 black, with more or less of its centre filled up or spotted with 

 red, orange, violet, blue, or (in the females sometimes) white. 

 Some species are more or less heavily marked with black at the 

 junction of the wings, and are also barred with black on the 

 hind-wings, and one or two of the females have extensive dusky 

 markings, leaving very little of the white ground-colour visible. 

 Thus C. achine (Cramer), the type of Wallengren's genus 

 Anthopsyche^'^' is one of these orange-tipped species, with dark 

 markings towards the junction of the wings, and a black 

 bar on the hind-wings in both sexes, broadest in the female. 

 The under side is white, with an orange streak on the hind- 

 wings. It is common and widely distributed throughout a 

 large part of Eastern and Southern Africa. A dwarf form, 

 sometimes measuring as little as i^ inches across the wings, 

 has been taken by Mr. Trimen in the Knysna district, and it 

 is interesting to note that the females, which otherwise vary m 

 this species more than the males, are likewise most variable in 

 size. According to Mr. Trimen's measurements, he has met with 

 females both smaller and larger than any males, though the 

 average size seems to be about the same. These observations 

 may be compared with our remarks on Euchloe carda/iii?ies 

 (a?ifea, p. 187). 



The Indian species are far less numerous and varied than 

 the African ones, and have all red or orange tips. One of 



* This group is closely allied to, if not identical with, Abccis,
