below median nervure to rather beyond origin of 3rd 

 nervule ; inner margin beyond middle tinged with 

 whitish-yellow in those specimens in which the marginal 

 spots are of that hue. Underside. — Hincl-ving, and costal 

 border and apical region oi fore-icing , n-hitish-yeJlou- ; the 

 extremities of all the nervures strongly defined with 

 black. Foye-wincj : spots as above ; more or less con- 

 spicuous fulvous internervular rays from hind-margin 

 stripe the yellow of apical region. Tlind-wing : spots as 

 above^ but larger, those of discal row often touching ; 

 below median nervure a black transverse stripe of three 

 contiguous spots extends to inner margin, and almost 

 touches the 8th and last spot of discal row ; base marked 

 with two rather large, black-edged pinh spots ; immedi- 

 ately before discal spots a row of pinh marks, indistinct 

 or obsolete near costa, but large and conspicuous towards 

 inner margin ; spots of hind-marginal border whitish- 

 yellow, and so much larger than above as to reduce the 

 black to a narrow edging ; before these spots are very 

 faint internervular fulvous rays. In both ■wings, the basal 

 black is wanting, but the costa is marked with a small, 

 distinct, black spot close to base. 



? . Semi-transparent grayish-ochreous ; an indistinct, 

 dusliy- whitish, costal bar outwardly bordering first three 

 spots of discal row ; black of hind-marginal borders 

 duller, rather broader. Fore-iving : an additional, elongate 

 spot, before middle, just below median nervure. Hind- 

 wiotg : a minute spot usually marking the 1st disco- cel- 

 lular nervule. Underside. — Yellowish colouring paler ; 

 internervular rays obsolete, or nearly so ; pink markings 

 of hind-wing duller, especially those on disk, which are 

 sometimes wanting. 



A $ specimen, taken in Kafi'raria by Mr. Bowker, has 

 the whitish-yellow costal scaling developed into a distinct 

 whitish bar like that of the $ ; and there is a similar, 

 but much smaller whitish marking on costa of hind- 

 wing.* 



This Aera^a is very distinct from all the described 

 species. It is intermediate between A. Bahira, Boisd. 

 (its nearest ally) and ^4. screna, Fab. Besides the bright 

 fulvous colouring of the $ , and the greater transparency 

 of the ? , A7iacreon may easily be distinguished from 



* It is remarkable that some examples of this Acnva, have the wings 

 much more elongated than those of the majority ; and in these the spots 

 and markings are more attenuated. This peculiarity is observable in 

 both sexes.
