On a new Species of Charaxes from the Cameroons. 449 



included in the definition of the family Stylophovidse. 

 Systematic ichthyologists in America emphasize differences 

 rather than resemblances, but this may be carried too far, 

 and I think the important features in the anatomy of Styh- 

 phorus are those which establish its relationship to the 

 Taeniosomi, whilst its unique characters are of interest only 

 as showing the remarkable specialization which the Tseniosome 

 type is capable of attaining.

Charaxes acrceoides, sp. n.

 side above the eye; antennas black; collar, tegulaa, thorax, 

 and abdomen black ; a white spot on the thorax just behind 

 the collar and two yellow spots on each side of the thorax ; 

 palpi above black, the underside orange-yellow ; the under-

 black. Primaries black, crossed near the apex by a band of 

 four elongated cream-coloured spots, the inner margin streaked 

 with red, above which are five large red spots, the one nearest 

 the anal angle the largest : secondaries red, black at the 

 base and partly along the inner margin, the anal angle and 

 part of the inner margin cream-colour ; a black streak at the 

 end of the cell, with the black spots on the underside showing 

 through ; the outer margin from the apex to the anal angle 

 black, with a series of minute white dots in the middle of the 

 black margin. Underside : primaries, the apical part of the 

 wing pale yellowish brown, the veins and streaks between 

 the veins black ; the cream-coloured band as above, edged 

 on the inner side by a band of black spots which extend 

 along the outer margin to the anal angle ; the cell and the 

 central part of wing greenish grey ; the usual black marks in 

 the cell ; the wing below the cell to the inner margin orange- 

 red : secondaries orange-red, palest above the cell and above 

 the anal angle ; the outer margins and veins all black; four 

 large black spots on the costal margin, four in the cell, and a 

 row of rive partly round the outside of the cell; the black 

 outer margin is spotted with blue and greenish-grey dots. 



Expanse 4^ inches. 



Hub. Cameroons, Bitje, Ja River, 2000 feet ; wet season 

 (Mas. Druce). 



This very tine species reminds one at first sight of Pseud- 

 acrcea clarki, Butler, which also came in the collection.
