distinguished by the difference in the white band on the primaries 

 and the bright carmine colour of the secondaries. Specimens are also 

 in the British Museum from the above locality and Old Calabar. 



Fam. NvCTEMERIDiE. 



AiiETis, Hiibn. 

 Alexis cunaxa, n. sp. (Plate LV. fig. 9, $ .) 



Male. Primaries hlack, with the basal half dark yellowish brown, 

 the brown on the outer side sloping off from the end of the cell to near 

 the anal angle on the inner margin, two white spots near the apex. 

 Secondaries dark yellowish brown, the outer margin broadly banded 

 with black from the apex to the anal angle, and much dentated in the 

 middle, a black streak from the base along the inner margin to the 

 anal angle. Underside orange, with all the black margins much 

 narrower and more broken ; four white spots on the primaries, the 

 first three close to the apex, the fourth at the anal angle, and five 

 on the outer margin of the secondaries, three near the apex and two 

 quite small, close to the anal angle. Head, antennae, thorax, and 

 upperside of the abdomen black, the sides of the abdomen with each 

 segment bordered with white, the underside dusky yellow ; the tegulse 

 black, spotted with white ; legs black. The female is rather larger 

 than the male and much paler in colour, and the black margins to the 

 wings are not so wide, and it also has a small black spot below the 

 end of the cell on the secondaries, like A. postica, Walk ; on the 

 underside it is almost identical with that of the male, the white spots 

 being slightly larger. 



Expanse, S I4 inch, 2 If inch. 



Eab. West Africa : Congo {Huson-3Iore). 



Terina, Walk.
