1896. ] FROM NYASA-LAND, 115 
As an example of the inconsistency of those lepidopterists who 
have been styled “ Lumpers,” Hewitson’s separation of two 
palpable forms of the present species is noteworthy. 
30. ACR#A EXCELSIOR. 
A Acrea excelsior, E. M. Sharpe, P. Z. 8. 1891, p. 192, pl. xvii. 
g. 3. 
3 3, Kondowi, Lower Nyika, W. of Lake Nyasa, April 4th and 
6th; 2 2, Nyankowa Mt., 6500 feet alt., April 9th; ¢, Lumpi R. 
valley, Lower Nyika, April 21st, 1895. 
“ Deep-bordered orange and black Fritillary ” (R. C.). 
This rare species is one of the most beautiful in the genus. 
31. ACREA VENTURA, 
Acrea ventura, Hewitson, Ent. Month. Mag. xiv. p. 51 (1877). 
3, Lumpi R., Lower Nyika; W. of Lake N yasa, Feb. 2nd; 
2, Nyankowa Mt., 5575 feet alt., Nyika, April 10th, 1895. 
“ Orange and black Fritillary.” 
32. ACR#A SERENA, yar. BUXTONI. 
Acrea buatoni, Butler, Ann. & Mag. Nat. Hist. ser. 4, vol. xvi. 
p. 395 (1875). 
3d, Deep Bay, W. coast of Lake Nyasa, Feb. 14th, and 
Ngerenge Plains, W. coast of Lake Nyasa, Feb. 24th, 1895. 
“ Small orange and black Fritillary ” (2. C.). 
Whether this is a race or a sectional form of A. serena can only 
be decided by breeding it ; but with our present extensive series 
I find it impossible to regard the following as distinct species :— 
A, serena=eponina=janisca = rougetii = manjaca= buatoni = per- 
rupta=balina. Probably the Linnean name terpsichore should 
stand over <A. serena, but there is so much doubt connected with 
the identification of that species that the better-known name 
seems preferable at present. 
33. ACRHA LYCIA, var. SGANZINI, 
Acrea sganzini, Boisduval, Faune Madag. p. 34, pl. vi. figs. 6, 7 
(1833). 
3, Mrali, W. coast of Lake Nyasa, March 2nd, 1895. 
“‘ Lesser speckled brown and white Fritillary ” (R. C.). 
A. lycia separates roughly into three forms, which are linked 
together by numerous intergrades ; they are— 
1. Acrea sganzint, vaguely resembling Limnas chrysippus. 
2. Acrea daira=usagare, like 1, but wanting black at apex. 
3. Acrwa lycia=braunei, pattern of 1, ground-colour white. 
Every link between these varieties is now represented in the 
Museum collection. A. daira appears to be an Eastern and 
Central-African sport of the species, occurring together with the 
two normal forms; it is completely linked to the A. syanzini 
type by intergrades, and therefore cannot be regarded as a race of
