TWO NEW SPECIES OF CHARAXES. 171 



general appearance of the living insect is yellowish-green and 

 brown with crimson hind femora : immature specimens are often 

 almost entirely rosy red. 



Unfortunately there has been considerable confusion in the 

 nomenclature of this species. Several specimens are in the 

 British Museum Collection, in the Hope Museum at Oxford, and 

 in the Dublin Natural History Museum, in each place labelled 

 flavipes. This is due no doubt to Donovan, who gives a good 

 figure of the species (Don. Nat. Hist. Brit. Ins. xii. p. 87, tab. 391), 

 but applies to it Gmelin's name flavipes. Mr. H. N. Eidley's 

 Kerry specimen was recorded as Pachytylus cinerascens, Fab., 

 which error probably arose through his finding, either in 

 Fisher's ' Orthoptera Europsea ' or in Brunner's ' Prodromus der 

 europaischen Orthopteren,' Locusta flavipes given as synonymous 

 with Pachytylus cinerascens — a mistake of both authors, the 

 second probably being due to the former (vide Eland Shaw, 

 Entom. Mo. Mag. 1889, p. 412 ; 1893, p. 20).

TWO NEW SPECIES OF CHAR AXES. 

 By the Hon. Walter Kothschild, Ph.D. 



1. Charaxes northcotti, sp. nov. 



$ . Allied to C. kheili, Staud. Fore wing on the upper side with 

 a series of heavy marginal pale blue patches ; a post-discal series of 

 spots, of which the upper four are small and more or less white, the 

 others larger and pale blue ; a discal series of five spots down to lower 

 median vein, the upper two white shaded at edges with blue, the 

 posterior three pale blue, the second and third the smallest, the third 

 closer to the cell than the others ; two dots at apex of cell, separated 

 from one another by the disco-cellular vein. On the hind wing there 

 is a large discal pale blue patch from upper radial vein to near anal 

 angle, about 6 mm. wide anteriorly, extending basad to near base of 

 upper median branch, with a small spot in front, its outer edge 

 somewhat concave between veins ; white submarginal spots small, 

 linear, much shaded with blue ; admarginal spots large, pale blue. 

 All the blue markings metallic. The under side does not present any 

 obvious differences from that of C. kheili. 



The series of discal spots on the fore wing and the large 

 patch on the hind wing distinguish this species from all the 

 allied ones. 



Hab. Gambaga, northern territories of the Gold Coast, one 

 male captured August 28th, 1898, by Major Northcott, to whom 

 I have the pleasure of dedicating this line species.
