1865.] MR. A.G. BUTLER ON THE SPECIES OF CHARAXES. 637 
margin of the front wings, where it becomes very indistinct ; on the 
hind wings distinct, close to the common lunulate line. Front wings, 
apex with a silver dash ; a silver streak at the anal angle. Hind 
wings, a marginal ferruginous line and asubmarginal row of greenish 
ocelli, the pupils black, at the outer edge of each ocellus. 
Hab. Celebes. B.M. 
Closely allied to C. baya, and only differs from it above in the 
absence of a ferruginous spot on the black near the anal angle 
of the front wing: on the underside the black lines are very differ- 
ently placed, the continuous submarginal lunulate line is more re- 
gular and very close to the outer margin, and none of the lines are 
so angular. We have two specimens in the Museum Collection ; and 
I have carefully compared them with all the other allied species, and 
find none that agree with them; and all these species resemble one 
another so closely in the coloration of the underside that, if the 
linear markings, which are locally constant (as far as I have been 
able to judge), are not taken into account, nothing is left to distin- 
guish the species but the depth of the black margin of the upperside. 
Note.—C. psaphon and C. baya exactly agree in the marking of 
the underside. We have a variety of C. baya that resembles C. 
marmax on the upperside. I think it very doubtful whether any 
of the species included in the present subdivision are more than 
varieties of one form; and Mr. William Atkinson, who has studied 
these insects in their native country and has compared numbers of 
specimens, assures me that they are all of one species.
