I8S8.] LEPIDOPTERA FROM KILIMA-NJARO. 97 



but after examination of a good series of specimens I have come to 

 the conclusion that these characters are constant. 



Mr. Jackson obtained three species of Papilio, — P. philonoe and 

 P. constantinus of Ward and P. ophidicephalus of Oberthiir : the last 

 mentioned does not differ from the southern type. 



Hesperiid^. 



Hesperia keithloa and H. bixce were obtained ; also Chcetocneme 

 cerymica, one or two obscure little species which have probably been 

 named by Monsieur Mabille or Herr Plotz, and the following : — 



10. Plesioneura biseriata. 



Nearest to P. galenus, a little larger ; primaries with the same 

 pattern, but the spot on basal area smaller ; secondaries with two 

 distinct sinuous series of orange spots, the inner series consisting of 

 seven spots, of which the second is large and diamond-shaped ; the 

 third and seventh reduced to mere points ; outer series consisting 

 of five decreasing spots, the first and largest bifid and touching 

 the outer margin ; fringe orange, divided by black lines at the 

 extremities of the veins ; discoidal spot indistinct ; secondaries below 

 paler than above, but similar in pattern ; in other respects this species 

 agrees with P. galenus. Expanse of wings 43 millim. 



Kilima-njaro {F. J. Jackson). 



HETEROCERA. 



Aellopus hirundo appears to be the common Hawk-moth ; Mr. 

 Jackson brought home six or seven specimens, but unfortunately 

 these and many others of his moths got more or less broken, owing 

 to some beetles getting loose and rattling about amongst them : 

 the following, however, fortunately came to hand in splendid 

 condition. 



ARCTIIDiE. 



Charidein^. 



11. Pompostola smaragdina, sp. n. 



Wings blue-black, the basal fifth and the costal border to the 

 end of the cell mottled with brilliant metallic emerald-green spots 

 and dashes ; two cuneiform spots, confluent behind, within the cell, 

 the inner one metallic green, the outer one hyaline white, richly 

 glossed with emerald-green ; a quadrate green-glossed hyaline spot 

 immediately beyond the cell ; a long oblique tapering green-glossed 

 hyaline streak from the median vein just below the double discoidal 

 spot almost to the external angle ; in some specimens, however, 

 this streak is widely interrupted in the middle, leaving only two 

 small spots ; a subcostal metallic green streak, from the centre of 

 which a transverse irregular green-glossed hyaline band runs almost 

 to outer margin at about apical fourth ; costal border of secondaries 

 rufous brown ; a small hyaline white subcostal spot, followed by a
