often very difficult to say to -which of these species certain specimens should 
be referred. With regard to var. insidaris described above, Dr. Staudinger 
agrees vnih me that it is a form of L. argus, and informs me that he has 
never previously seen such pale specimens.

Only one specimen of this species appears to be known ; this was in 
Mr. Fenton's collection, and is figured in 'Aid.' As I have not seen the type 
I am unable to say anything postively about its being a valid species or not, 
but the figui'e seems to represent an insect specifically distinct from either 
L. argus or L. oegon. In the description of this species the fringes are stated 
to be snow-white, but in the figure the fringes are chequered with black and 
white on the upper surface, but are entirely omitted in the drawing of the 
under surface.
