 Hesperia ilias, Ploetz, S. E. Z. vol. xl. p. 355 (1879). 

 Hab. Q-uinea {Ploetz) ; Gaboon. 



What I take to be the Hesperia ilias of Ploetz — forming iny 

 conclusion from the description of the species given by the author 

 and from a copy of his unpublished drawng of the same — is the 

 insect figured on the Plate, It comes nearer meeting the require- 

 ments alike of description and of figure than any other West- 

 African species known to me in nature. 



225. B. XYLOS, Mab. (Plate II. fig. 13.) 



Pamphila xylos, Mab. Ann. Soc. Ent. Prance, (6) vol. x. p. 31, 

 pi. iii. fig. 8 (1890). 



ffal. Gaboon, Cameroons, Sierra Leone. 



Mons. Mabille (I. c.) states that he has sufficiently characterized 

 this species in the ' Bulletin ' of the preceding year, and contents 

 himself therefore with a figure. By reference to the ' Bulletin ' 

 for 1889, I discover that his memory was at fa,ult. He did not 

 describe P. xylos in the ' Bulletin ' of the year before. Our only 

 knowledge of the species, therefore, must be derived from the 

 figure given in the plate, which, fortunately, is quite recognizable. 

 It represents a damaged male of a species which is quite common 

 on the tropical western coast of Africa. I have a long series of 

 specimens in which, singularly enough, the females are more 

 numerous than the males. The figure given by Mons. Mabille is 

 that of a male minus the abdomen. The female which is repre- 

 sented in <the plate does not differ materially in the location and 

 style of the marking from the male, but is generally much larger. 

 I discovered that Mons. Mabille had mingled with this species, in 

 his collection and that of Dr. Staudinger, specimens of the 

 following species, which is abundantly distinct, though presenting 

 a superficial likeness. 



226. B. ALBBETi, sp. uov. (Plate 11. fig. 21.) 



cT . Body and appendages black. Abdomen produced beyond 

 the anal angle of the secondaries. The wings on the upperside 

 are black, with whitish fringes, those of the primaries checkered 

 with blaclc at the ends of the nervules. There are no spots on 

 the secondaries. The primaries are ornamented with three small 

 subapical spots in the usual position, by two large and conspicuous 

 subquadrate spots, one on either side of vein 3 at its origin, the : 

 upper one being the smaller of the two. In many specimens 

 there is also a small and faint spot on cell 1, just below the large 

 subquadrate spot on cell 2. On the underside, the wings are 

 marked precisely as on the upperside, save that the inner margin 

 of the primaries is pale, and in some specimens there are traces of 

 an obsolete series of pale submarginal markings on the secondaries. 



2 . The female is marked like the male, save that on the under-
