[Eeeeived December 6, 1887.] 

 (Plate LV.) 



The specimens from which these descriptions are taken are all in 

 my own collection. 



Fam. Agaristid^. 

 EusEMiA, Dalman. 



EUSEMIA PERDIX, U. Sp. 



Primaries black, witli all the markings orange-yellow ; the apical 

 spot smaller and narrower than in E. superba ; the two central and 

 tlie anal spots about the same as in that species ; the band 

 near the base crosses almost from the costal to the inner margin, 

 thus differing from E. superba ; the basal white spots are the same, 

 the bluish lines are very indistinct. Secondaries bright carmine, 

 with a yellowish shade on the costal margin ; the outer margin 

 broadly banded with black ; a red spot on the black band near the 

 anal angle. The fringe white at the apex of all the wings. Head 

 and thorax black, spotted with white as in E, superba ; abdomen 

 black, banded with yellow ; antennae black. Both sexes are 

 identical. 



Expanse, S and 2 2f inches. 



Hab. East Central Africa : Manboia (Last) ; Delagoa Bay 

 (3Irs. Monteiro). 



This fine species is allied to Eusemia superba, from which it is at 

 once distinguished by the basal band on the primaries and the red 

 spot on the black margin of the secondaries. I have four specimens 

 before m.e, two c? and two 5 . 



Eusemia pentelia, n. sp. 



Primaries deep black, Avith two bluish metallic streaks, the first 

 about the middle of the cell, the second at the end of the cell ; 

 the ochraceous spots and bands arranged much as in E. euphemia, 

 but the apical band is much wider and more curved, and almost 

 joining the small spot at the anal angle. Secondaries ochraceous, 

 shaded with carmine at the base and along the inner margin to the 

 anal angle ; the outer margin broadly banded with black, widest at the 

 apex and the anal angle. Underside as above, the secondaries being 

 rather more pink in colour. Head, thorax, palpi, and antennae black, 

 the thorax and tegulae spotted with white ; abdomen black, each 

 segment banded with yellow, the first three bands nearest the base 

 whitish on the upperside. 



Expanse 2 inches. 



Hab. East Africa : Delagoa Bay (Mrs. Monteiro).
