58 Dr. A. G. Butler on 
Species new to the Museum and others poorly represented 
in our cabinets are in this collection, also a remarkable series 
of Charaxes epijasius which we had previously received from 
Senegal, Abyssinia, and the White Nile; both wet and dry 
phases of Prects antilope occur. 
Five examples of Zeritis amine are in the collection; with 
regard to this species, which Prof. Aurivillius assumes to be 
the Z. neriene of Boisduval, one must note what the Professor 
himself says :—‘‘ In Boisduval’s figure of Zeritis neriene the 
neuration, as usually in the figures of this author, is quite 
incorrectly figured, and the hind wings drawn from an 
example in whick the tails were broken off.’ To this note 
may be added that the Z. nervene of Boisduval is not 
described, the upper surface of the wings is not figured, the 
under surface (if intended to represent what I described as 
Z. amine) is quite incorrect in pattern, the anal lobe is 
omitted, and, lastly, the locality is uncertain, though Bois- 
duval thought it might be Guinea. In short, we have no 
evidence whatever that Boisduval’s insect was intended for 
‘‘ Z. amine,” beyond a general similarity in the pattern of the 
under surface. His insect may have been generically distinct, 
the upper surface may have been entirely dissimilar, the 
locality may have been anywhere in the Hthiopian Region. 
Without evidence no species should be sunk into the rank of 
a synonym, nor should an acknowledged utterly incorrect 
and partial illustration of an undescribed insect be ranked as 
of any scientific value ; if proved to be fictitious, it should be 
treated exactly in the same way as Petiver’s figure of Papilio 
ecclipsis, and ignored. 
Two other Lycenide of interest were obtained—Cato- 
chrysops cyclopteris and Chilades alberta; the first an 
Abyssinian form, the second an insect occurring in Equa- 
torial Africa. Inthe Pierine the Hastern Teracolus opalescens 
occurs, whereas I should have expected that either 7. matmuna 
or Z. eris would have been the representative form of 
Northern Nigeria. However, to anyone with an eye for form 
and pattern it is impossible to mistake one insect for the 
other, the outline of the white area in the primaries of the 
males being most characteristic: the apical spots, however, 
are rather characteristic of the Western than the Kastern 
form; and if this peculiarity of Nigerian examples should 
prove to be constant, it might become necessary to regard 
them as representing another subspecies of the 7’. ers group. 
Two males of Caprona adelica were obtained, corresponding 
in all respects with Karsch’s figure of the female; it therefore 
seems probable that M. Mabille confounded two species under
