220 Mr. S. A. Neave: some bionomie 
punctatissima, Boisd. (150), is the model. Two species of 
Lyceenidze are associated with it, viz. :— 
Pentila petreia, Hew. (24). 
»  clarensis, Neave (10). 
Norr.—Prof. Poulton informs me that he discovered two specimens 
of P. amenaida, Hew., placed among the Acreas in the Hope 
Collection by Professor Westwood. 
Another synaposematic group among the Acrzeinz con- 
sists of the larger red and black species, viz. :— 
A. egina, Cram. (21). 
A, perenna, Dbl. and Hew. (42). 
A, zetes, Linn. (7). 
A, pharsalus, Ward (8). 
A. ovina f. orinata, Oberth. (6). 
These species belong to no less than three different sub- 
divisions of the Acrvine. 
These species—especially A. egina—are resembled closely 
by Papilio ridleyanus, White (4). 
Pseudacrxa boisduvali, Dbl., though not in the Wiggins 
or Harrison collection, was obtained by Mr. A. W. Hobley in 
the same district, and also closely mimics A. egina. 
Monura zingha, Cram, (1), is probably an outlying 
member of this red and black group. 
It is by no means improbable that the outlying gigantic 
mimic, Papilio antimachus, Drury, will also ultimately be 
found here. 
MIMICRY IN OTHER GROUPS. 
Atella phalantha (144), so common all over Africa, 
occurs plentifully in the collection, together with its mimic, 
Pseudargynnis hegemone, Godt. (35), from many of the 
same localities. Asis so often the case, the resemblance 
is closer in the § than in the ¢. 
Mimicry among the Prerine. 
Three very differently coloured species of Mylothris form 
the models of three well-marked groups. 
I. Mylothris jacksoni, K. M. Sharpe, with white fore wings 
and sulphur-yellow hind wings, is only represented by a
