warm brown tinge. Underside pale sepia ochreoiis somewhat dark 

 on f.-w. apex, and h.-w. base and margin. 

 5 . Like the ^ . 



A. rogersi lambortii, subsp. n. PL VI, f. 2 (larva), f. 16 (pupa). 



Long series of this form have lately been bred by 

 Mr. W. A. Lamborn near Lagos and presented by him to 

 the Oxford Museum. 



The cJ has the f.-w. sooty black, rather paler in the central 

 area. H.-w. base and marginal border sooty black with a broad 

 discal band of dusky cream colour. The spot near base of 3 

 usually absent. Underside f.-w. apical area to end of nervule 2 

 sepia grey with darker internervular rays, remainder pale greenish 

 grey. H.-w. pale creamy grey with a yellowish tinge, and a faint 

 pinkish tint at base of Ic, lb, and la. 



Head and thorax black with some whitish spots. Abdomen, 

 basal half black with whitish segmental lines and lateral spots 

 remainder pale creamy grey. 



$ resembles the (J. 



The larva of A. rogersi lamborni is dark brown somewhat 

 blacker on the dorsal area, with a few irregular rather paler 

 dorsal transverse markings, and has the usual spines which are 

 all black and arise from black-brown tubercles. The base of the 

 legs and prolegs is yellowish, remainder black. Head black 

 with a white central line bifurcated ventrally, and a posterior 

 white line where it joins segment 2. 



The pupa differs from other Acraea pupae which I have 

 examined. It is light brown in colour, and the usual black 

 lines are wanting, except those outlining the antennae, and a 

 trace of some of the nervular lines. There are two dorsal and 

 two lateral rows of small black markings consisting of minute 

 dots and short fine transverse streaks, and a ventral row of 

 dots and streaks, the latter longitudinal. On the head ai'e two 

 short, blunt, widely separated, outwardly curved processes giving 

 the pupa a " horned " appearance. There are very slightly 

 raised dorsal abdominal tubercles visible only with a lens. 



The species is not uncommon and is easily distinguished 

 from other Acraeas by the large round black spots in 

 li.-vv. 



There is one ^ example in the Staudinger collection 

 labelled German E. Africa, but the occurrence of the species 

 in that region is extremely doubtful.
