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. stenobcea = lig>(s is only a bright-coloured and more opaque 

 phase of A. ccecilia.

" Orange and black, crimson and pink underwinged Fritillary. 

 Have only seen this one specimen " (E. (7.). 



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 Lycsenida3 of the collection contain a nice series of the new 

 genus Uranothauma and several other forms of interest.

Marbled white Skipper (E. <?.). 



These specimens are interesting, three of them being white- 

 banded as in typical A. nyassce, 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.
