by its larger, paler, less warmly-tinted apical patch ; total, or almost 

 total, absence of black nei-ynles in both wings ; want of copious black 

 irroration in fore-wing, and presence of strongly-marked irroration 

 stripe on costa of hind-wing : the under side is somewhat more 

 yellowish.^ The $ has a much larger apical patch, owing to the 

 breadth and extension inferiorly of the fuscous-brown on its inner 

 border ; but wants the disco-cellular terminal spot presented by Agoye 

 $ in both wings : the under side is duller in tint, and wants both the 

 disco-cellular spots and the tinge of pale yellow at the base of the 

 fore-wing. 



As above noted, I referred the first example seen of this form to Agoye, 

 Wallengr., but the subsequent receipt of individuals of both sexes has shown 

 me that it is quite distinct. Colonel Bowker, after whom I have named the 

 butterfly, captured the first specimen in Basutoland. In 187 1 he sent a second 

 $ from Hope Town, on the Orange River, and, later in the same year, a <^ and 

 four 9 s from the A^aal River. On the 6th September 1872 I took a single (J 

 at Kolberg, in Griqualand West, on the flowers of a fine species of Cineraria 

 growing on a rocky hill. This example flew rather slowly.^ Mrs. Barber also 

 forwarded, in 1879, a (^ from the Vaal River. Mr. L. P^ringuey, who dis- 

 covered the Variety A. above noted, informs me that he met with it only at Spec- 

 takel ; the specimens taken were flying not rapidly about a rocky " kopje" of 

 some elevation, in company with some other congeners, on the nth November

- Mr. H. L. Langley Feltham, from whom I have lately received a 9 with unusually 

 dark and well-developed apical marking (taken at Kimberley on 20th November 1887), 

 informs me that this butterfly has in his experience occurred but very sparingly in and about 

 Kimberley. He gives the following dates, viz. : 1884 — May 4th, ? ; December 14th, $ ;
