118 DR, A. G. BUTLER ON BUTTERFLIES [Jan. 14 
This species varies in tint, from semitransparent greyish bone- 
colour to almost opaque orange tawny ; the spots vary in number 
and size, and the apical border of primaries in width: it is this 
inconstancy in the present species which convinces me that 
A, stenobea=ligus is only a bright-coloured and more opaque 
phase of A. cecilia.

“ Orange and black, crimson and pink underwinged Fritillary. 
Have only seen this one specimen” (2. C.). 
This is a very variable species ; not only does it differ greatly in 
the width of the black border of secondaries (on which character 
I based my A. arcticincta), but in the size and number of the black 
spots on the primaries. One of our 31 examples, in addition 
to the basal black patch, the bar beyond the end of cell, and the 
apical patch, exhibits five well-defined discal black spots, all of 
which are absent in some specimens, it also shows a conspicuous 
black spot on the lower discocellular veinlet. 
The Lycenide of the collection contain a nice series of the new 
genus Uranothauma and several other forms of interest.

“ Marbled white Skipper ” (2. C.). 
These specimens are interesting, three of them being white- 
banded as in typical A. nyasse, but with the subapical white spot 
of var. ochracea; the fourth example has a white band across the 
primaries, but a buff band across the secondaries, thus proving that 
I was correct in not regarding A. ochracea as a distinct species.
