440 DE. A. G k BTTTLEH'otf LEPIDOPTERA [May 17, 



Unfortunately only one slightly damaged example of this 

 beautiful species was obtained l . 



216. ARNIOCEBA CYANOXAKTHA. (Plate XXXIII. fig. 5.) 



$ . Zyymna cyanoxaniha, Mabille, Ann. Soc. Ent. Belg. 1893, 

 p. 57; Mabille and Vuillot, Novit. Lep. fasc. xii. p. 151, pi. xxi. fig. 6. 



Samburu, 10th November, 1896. 



One typical male differs from Mabille's figure in the loss of the 

 orange spot below the subapical one ; the other examples have all 

 the spots brilliant crimson instead of orange : the name for the 

 species is therefore not very characteristic. The specimens are not in 

 specially good condition, so I hope Mr. Betton will obtain others. 



217. AIIISTOCERA IMPEEIALIS, sp. n. (Plate XXXIII. fig. 6.) 



d . Primaries above shining Prussian green, changing to blue at 

 outer margin, five black-edged carmine spots (the two central ones 

 sometimes confluent, forming a transverse band) as in A. cyano- 

 xaniha, fringe purple flecked with copper : secondaries with the basi- 

 costal half bright rose-colour, tinged with orange at base ; outer half 

 bright Antwerp blue, changing to purple on the fringe ; an ill-defined 

 subapical cluster of rosy scales : thorax glittering steely green, 

 yellowish on centre of dorsum ; sides of face purple ; palpi carmine ; 

 sides of collar and inner border of patagia crimson ; metathorax 

 with sides and hind margin orange ; abdomen orange-vermilion, 

 tinted with carmine at the sides, basal segment greenish black. 

 Primaries below bright blue, spots as above, but more vermilion ; 

 base of cell varied with golden testaceous : secondaries rose-red, 

 with a basi-costal dash and a longitudinal costal streak blue ; a 

 squamose blackish streak from end of cell to extremity of vein 1 ; 

 fringe greyish coppery at apex : body below blue-black ; anterior 

 coxae orange-vermilion ; a golden line along inner edge of tibiae ; 

 middle tibiae carmine with black tips ; posterior tibiae with long 

 cream-whitish pencil of hairs. Expanse of wings 32 millim. 



Samburu, 10th November, 1896. 



Two tolerably good examples of this lovely moth were obtained. 



1 The following beautiful new species was presented to the Museum by 

 Dr. Edward A. Heath : 



ARNIOCERA ERICATA, sp. n. (Plate XXXIII. fig. 4.) 



Primaries glossy greenish black ; a broad irregular subbasal belt, a bilobed 

 oblique postmedian abbreviated band, and a large ovate oblique subapical patch 

 scarlet : secondaries with ochreous costal area, otherwise the basal halt' ver- 

 milion, with an irregular submedian basal blue-black patch ; external half 

 blue-black, throwing a long inner process up vein 1, enclosing a large scarlet 

 subapical spot, and slightly sprinkled with scarlet along outer margin: thorax 

 greenish black ; abdomen scarlet, transversely banded with indigo-blackish ; 

 antennas and palpi black ; anterior legs greenish black ; tibiae slightly testaceous 

 internally, tarsi with reddish short bristles ; middle legs with the femora 

 greenish black, slightly chestnut below (possibly owing to abrasion) ; tibiae 

 clothed with scarlet hair, with tip and spurs black ; tarsi brown ; hind legs a 

 good deal rubbed, but apparently similar to the middle pair : wings below 

 nearly as above, but the primaries broadly orange at the base. Expanse of 

 wings 34 millim.
