1896. ] ON LEPIDOPTERA FROM NYASA-LAND. 851 
6. On a Collection of Lepidoptera from Nyasa-land presented 
to the Museum by Sir Harry Johnston, K.C.B., and

From the few notes as to exact localities which occurred on the 
envelopes it would seem that the present collection was obtained 
partly, if not altogether, on the Songwe plain, N.W. Nyasa, in 
1895; but so very few of the specimens are accompanied by 
notes as to locality and date of capture, that I have not thought 
it advisable to burden the ‘ Proceedings’ by repeating references 
to descriptions and figures, most of which have already been given 
in other papers on Nyasa Lepidoptera published in the Society’s 
‘ Proceedings.’ 
The collection contains examples of five new species and of a new 
form of a known species ; but, in addition to these, there are several 
species of interest, such as the wet-season form of Ypthima gra- 
nulosa ; examples of the broad-bordered variety of Charawes saturnus, 
to which I gave the name of laticinctus; a somewhat worn female 
example of the rare Charawes violetta ; the white variety of Zuralia 
mima; additional examples of Metacrenis crawshayi; a curious 
variety of the female of Alena nyasse having the base of the pos- 
terior wings white; both wet- and dry-season forms of Teracolus 
opalescens ; the rare Teracolus hildebrandtii; a dry-season female 
of Teracolus subfasciatus, differing in its superior size, the larger 
apical orange patch on the primaries being without inner blackish 
limitation, and the under surface more strongly reticulated ; both 
seasonal forms of Teracolus emini; the male of Belenois diminuta, 
showing that the latter is the dry-season form of B. crawshayi; a 
good series of Papiho nivinow, consisting entirely of males (as the 
only example which we possess of P. taboranus is a female, it 
seems probable that the differences in pattern and colouring 
between these two forms of Papilio are due to sex, in which case 
the name of P. taboranus will have to stand for the species); 
an example in good condition of a rare Hesperiid (Cyclopides 
willemt), of which the Museum previously only possessed a broken 
example. 
Among the Moths, the most interesting additions, apart from 
the new species, are two male examples of Hibrildes norax. 
Respecting Hibrildes we know very little at present: if the female 
resembles the male, no examples have hitherto been received ; but 
it is possible that the sexes may be entirely dissimilar, and that 
my Hibrildes crawshayi may eventually prove to be the female
