266 Dr. A. G. Butler on a new Species of Charaxes. 



XLIV. — Description of a new Species of the Butterfly Genus 

 Charaxes. Bj Arthur G. Butler, Ph.D., F.L.S., 

 F.Z.S., &c. 



For many years a species of the genus Charaxes has been 

 confounded with the well-known C. ethalion of Natal and 

 Delagoa Bay. As I have recently been through the whole 

 of the literature relating to the genus and have failed to 

 identify it, I now propose to describe it as 



Charaxes Hollandii^ sp. n. 



(J . Chiefly differs from C. ethalion ^ {ephyra, Godt.) in 

 the deeper excavation of the outer margin of the primaries 

 and the longer abdominal margin of the secondaries ; on the 

 under surface, however, the wings are much richer in 

 colouring, the black markings much more heavily delineated, 

 and the central belt washed with silvery glaucous ; the spots 

 beyond this belt are also darker and, on the primaries, more 

 numerous. 



Expanse of wings 72 millim. 



? . Above far more like a dwarfed female of C. imperialis 

 than like C. ethalion ; blue-black, the primaries with three 

 small lilacine spots in a triangle beyond the cell, the apex of 

 the triangle being directed obliquely downwards towards the 

 base of the third median branch ; below these two increasing 

 spots of the same colour in the median interspaces ; between 

 the latter and the inner margin a bright blue band, con- 

 stricted above the submedian vein ; nearer to the outer 

 margin a biangulated almost ^-shaped series of seven spots, 

 of which the upper six are lilacine wuth white centres and 

 the seventh bright blue ; central belt of secondaries bright 

 blue ; in other respects tolerably close to C. ethalion : below 

 the wings have a glaucous gloss, especially on the paler 

 bands, and in some respects the pattern more nearly resembles 

 that of C. etheocles. 



Expanse of wings 82 millim. 



Sierra Leone. 



I have named this pretty little species after my valued 

 friend Dr. Holland, of Pittsburg, whose many important 

 contributions to our knowledge of the Lepidopterous fauna of 

 West Africa are widely known.
