140 EHOPALOCEEA. 



Adult males representing the species of each of these genera may readily be distin- 

 guished as follows : — 



A. Terminal joint of palpi very short in both sexes. 



a. Base of inner margin of primaries furnished with long hairs, a patch of 



densely felted scales above the subcostal nervure of secondaries . . . Catopsilia. 



b. Base of inner margin of primaries simple. > 



a 1 . A patch of densely felted scales between the costal and subcostal 

 nervures of secondaries above and a corresponding patch between 

 the median and submedian of the primaries beneath Callidryas. 



V. A pencil of hairs below the subcostal nervure of secondaries and a 



patch of densely felted scales above the subcostal Rhabdodryas. 



c'. A pencil of hairs below the subcostal nervure of secondaries, but no 



patches of felted scales on either wings Phcebis. 



B. Terminal joint of palpi in female much longer than in the male Aphrissa. 



The first of these takes the whole of the Old-World species, with which we do not 

 deal in the present work. 



The divisions in the second set of genera are all more or less borne out by the secondary 

 male characters, except that Phcebis and Callidryas seem more closely connected with 

 each other than they are to either Rhabdodryas or Aphrissa. The wing-neuration in all 

 these genera is very uniform, and affords no tangible generic characters. The subcostal 

 nervure emits three branches ; two before the end of the cell and one a little beyond it. 

 There is no upper discocellular, the upper radial meeting the subcostal beyond the cell. 

 The terminal joint of the palpi, except in the female of Aphrissa, is very short, the second 

 joint subelliptical and about half the length of the basal joint. The harpagones in 



C. philea have the ventral edge produced into a long rod, and the dorsal edge bears in 

 the middle a strongly recurved slightly dentate process ; attached to the inner surface 

 is a strong lobe, expanded towards its distal end and set with long strong spines. In 

 C. eubule the harpagones are very similar, but the ventral edge is not so prolonged ; 

 moreover, the patches of densely packed scales in the wings of the latter species are 

 not nearly so well defined as they are in C. philea.
