by its larger, paler, less warmly-tinted apical patch ; total, or almost 
total, absence of black nervnles in botli wings ; want of copious black 
irroration in fore-wing, and presence of strongly-marked irroration 
stripe on costa of liind-wing : the under side is somewhat more 
yellowish.-^ The $ has a much larger apical ^^atch, 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 1871 he sent a second 
$ from Hope Town, on the Orange River, and, later in the same year, a ^ and 
four 9 s from the Yaal River. On the 6tli 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. P6ringuey, 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 
Localities of Teracolus Bowkeri.
