in Trans. Ent, Soc. Lend.. 1871. p. L69 : PI. VII, fig. 7, as 

 Ixias venatus. The male of this form was unknown until 

 1902, when Mr. Loat captured one at Grondokoro; this 

 was described in Trans. Ent. Soc. Loud., 1903. p. 152. 

 The male type and a female from Shambi on the White 

 Nile were well figured by Dr. LongstafT.* P. simana, as 

 already stated, was described by Hopft'er from Mozambique. 

 Both sexes are figured by Peters.f The name venata is 

 not inappropriate to Butler's type, which is somewhat 

 heavily marked, and has the veins accentuated with black. 

 In many other female specimens (probably of the dry 

 season), and in all the males with which I am acquainted, 

 the black veining is absent from the upper surface. In 

 P. simana, on the other hand, although the females vary 

 in this respect, probably, like those of P. venata, according

to season, the males appear always to have the veins 

 on the upper surface more or less marked out with black. 

 On these and other grounds presently to be mentioned, 

 1 think that simana and venata, though no doubt closely 

 allied, are separable as subspecies. 



It may then be said, at least provisionally, that there 

 are four, or perhaps five, subspecies which can be ranked 

 under the head of Pinacopteryx charina. It will be of 

 interest to see what light can he thrown on the mutual 

 relations of these forms by an examination of structural 

 details. 



(1) The Male Genitalia. — As already remarked, the 

 clasper in all these tonus ends posteriorly in a single 

 spinous projection. This in a specimen of P. liliana from 

 Mombasa is long and slender (tig. •'!). In an example of
