wider at the top of the hind declivity than at the base, plainly tricostate on 

 each side, with the suture also raised as high as the dorsal costae, but the outer 

 margin, although nearly equally high, is sharper; the intervals have no traces 

 of costnles, and are finely granular; anterior tibia strongly bidentate outwardly, 

 simple at apex, without any apical vertical process underneath, and not serrate 

 inwardly. 



Length, 26 mm. ; width, 12J mm. 



Allied to A. sculpturatus Per. and to A. asidioides Oertz. It differs from 

 the former in the absence of a vertical process underneath the apex of the anterior 

 tibiae, and from the latter, the anterior tibia of which has the same shape, in 

 the sculpture of the prothorax. 



A NEW AFRICAN MELANITIS. 



By tile HON. WALTER ROTHSCHILD, Ph.D. 



Melanitis ansorgei spec. nov. 



S. Upperside of wings purplish violet, blackish towards the apex of the 

 forewing, without ocelli ; a white subapical band on forewing extending from 

 costal edge towards marginal projection of wiug : fringe of forewing more or less 

 dirty white from apex to middle, except at veins; hindwing (of c?) with a grey 

 elongate-ovate scent-organ in front of SM^ just beyond middle, the patch covered 

 by a fringe of long hairs projecting from SM' discad. Outline of wings somewhat 

 similar to that of lihi/a, but the distal margins more even, the jwsterior portion 

 of the distal margin of the hindwing much more slanting, being almost parallel 

 to the hinder margin of the forewing if this margin stands at right angles to 

 the body. 



Underside olive-bistre, irrorated with grey, the grey scaling forming patches, 

 being densest on forewing at apex, across middle of cell, and posteriorly on 

 disc, and on hindwing from near base to middle of cell, and along costal margin ; 

 a large anal area of hindwing extending as far as apex of cell washed with 

 purple-grey ; a series of vestigial submarginal ocelli on both wings ; a small white 

 stigma at apex of cell on fore- and hindwing, the stigma of the hindwing being 

 the larger. 



Length of forewing : 35 mm.
