towards the inner portion of the wings near the body. There is a 

 slight black tip to the forewing, which is continued as a narrow 

 border some way along the cos La or upper margin and also on the 

 outer margin, but here the black is rather disconnected. The thorax 

 is clothed with silky hairs, which are longer near the abdomen. 

 There are also some long silky hairs on the hindwing near the 

 body. On the inner margin of the forewing there is underneath a 

 kind of brush formed of the same kind of silky hairs, and on the 

 corresponding upper portion of the hindwing there is an oval patch 

 of scales closely pressed together and of a different structure to the 

 scales which form the colouring of the wings, for these appear under 

 the microscope to be hollow like bladders, whereas the ordinary 

 scales are flat and tile-like. The underside of the wings is always 

 marked with reddish streaks, and on the forewing (underside) there 

 is one silver-pupilled ocellus encircled with red, while on the 

 hindwing (underside) are two similar ocelli. The use of the peculiar 

 brush and patch of scales on the wings is not known, but all the 

 males of this genus possess them. In fresh specimens there is a 

 peculiar faint perfume something like primroses to be observed in 

 the male only. The female is of a deep rich yellow, the forewing 

 with a similar border as in the male, with the addition of a black 

 spot in the middle of the wing; underneath the mai-kings are more 

 decided and of a richer tint. In some specimens the ocelli are 

 surrounded by a richly coloured patch, in which pink, brown and lilac 

 are mingled. The antennse are pink. The flight cf all the butter- 

 flies of this genus is very vigorous, and they always settle with their 

 wings closed. 



93. Catopsilia crocale, Cramer. The male of this species is on the 

 upperside very much like that of the last, but is rather more 

 pervaded with yellow. It is not quite so large as a rule, and the 

 black tip and border to the forewing are slightly more perceptible. 

 The underside is almost unmarked and of a pure yellow, slightly 

 paler on the forewing, where it is covered by the hindwing when 

 the butterfly is at rest. The female has more black than any other 

 of the genus, as both wings are bordered with that colour, and there 

 is a sort of inner border formed by a series of dark marks, while the 

 base of the forewing in some specimens is suffused with black.
