Genus Charaxes Ochsenheimer. 



For a number of years there has been in our collection of African 

 Charaxes a female specimen, which I have hesitated to describe, 

 thinking that perhaps it might be the female of a species, the male of 

 which has already been named. As students well know, there is in 

 certain of the species of this interesting genus great dissimilarity 

 between the two sexes, though there is generally some clue to relation- 

 ship furnished by the markings of the under side of the wings. Having 

 recently had occasion to go over the material in our possession, in 

 which almost all the known species of the genus are represented, I 

 am led to conclude that I am dealing with an insect which has not 

 been as yet named, and I venture therefore to describe it as new. 



I take pleasure in naming this insect in honor of Mrs. Lydia Good, 

 the noble woman who shared with my friend, the late Rev. Dr. A. C. 

 Good, the trials and joys of those years in which he so successfully 

 labored as a missionary and man of science in Africa, where she bore 

 to him the son, who with distinction has taken his father's place.

The antenna? are black. The palpi are black above, brilliant white 

 below. The front and head are black, with a minute white spot be- 

 fore and behind the insertion of each antenna. The upper side of 

 the thorax is clothed with whitish gray hairs, the upper side of the 

 abdomen is whitish, with the hind edges of the six posterior segments 

 marked with black. The pectus and lower side of the abdomen are 

 white. The legs are white below, black above. Upper side of wings: 

 The fore wing at the base is densely clothed with glaucous gray 

 scales as far as the middle of the cell, but through this vestiture the 

 dark markings at the base of the cell on the lower side faintly appear. 

 The end of the cell is deep black, but with a small trapezoidal white 

 spot intervening between the black area and the glaucous gray area 

 at the base. A broad white triangular area, extends upward from 

 the inner three-fourths of the margin to the origin of vein 3, but 

 does not reach the outer angle. The remainder of the wing above 

 and beyond this white area is black, ornamented with conspicuous 

 white spots. At the outer angle is a triangular white spot. Above 

 this spot, between the extremities of veins 2 and 3, there is a lanceolate
