137. LEPIOSOMA APICALE. 



Nyciemeraapicalis, Walker, Cat. Lep. Het. ii. p. 395 (1854). 

 2 $ , Deep Bay, May 16th, 1895. 

 " Light yellow "ova" (E. C\). 



138. SPILOSOMA AURICINCTUM, sp. n. (Plate XLII. fig. 6.) 



Nearest to S. purum (Alpenus purus\ but easily distinguishable 

 from the fact that the head and the collar are bordered at the back 

 with bright ochreous ; the primaries are more produced, the costal 

 margin being longer and the black dots are few, small, and confined 

 to the base and costal area; the secondaries only show three 

 conspicuous black spots in the form of a triangle, the apex of which 

 is represented by a spot at the end of the cell and the base by two 

 submarginal spots ; primaries below immaculate, but secondaries 

 as above. Expanse of wings 44 millim. 



$ , Euleriva hills, 2000 feet alt., Deep Bay, March 5th, 1896. 



This species and S. purum are strikingly unlike the other Ermine 

 Moths from the fact that both extremities of the bright golden- 

 ochreous black-dotted abdomen are snow-white. Our examples of 

 S. purum from British East Africa show no trace of the dorsal 

 black dots, but otherwise are typical. 



139. AROA TERMINALIS. 



Aroa terminal, Walker, Cat. Lep. Het. iv. p. 794 (1854). 

 <?, Kondowi, 4000 feet alt., Nyika, Feb. 21st, 1896. 



Walker's description, having been based upon a badly rubbed 

 and barely recognizable specimen, is utterly useless for the iden- 

 tification of the species ; I therefore redescribe the insect from 

 Mr. Crawshay's beautiful male example : Primaries above deep 

 yellowish testaceous or bright mustard-yellow ; a paler central 

 band with widely bisinuated outer edge, expanding within the 

 cell to enclose a conspicuous rounded blocd-red spot ; a pale 

 band crossing the disc near the outer margin, its inner edge bi- 

 sinuated, its outer edge correspondingly biundulated ; fringe very 

 slightly paler than the ground-colour ; secondaries deep orange- 

 ochreous with bright golden yellow fringe ; antenna? yellow, with 

 vinaceous brown pectinations ; body ochreous, deepest on the 

 abdomen : under surface bright saffron-yellow, the primaries 

 irrorated with smoky brown scales towards apex forming two short 

 divergent streaks; legs hairy, lemon-yellow. Expanse of wings 

 33 millim. 



Kondowi, 4000 feet alt., Nyika, Feb. 21st, 1896. 



I believe the specimen noted (P. Z. S. 1896, p. 135) as Lopera 

 crocata var.? is probably a very badly discoloured and faded example 

 of this species. 



140. AROA BISTIGMIGERA, sp. n. (Plate XLII. fig. 7.) 



d . Nearest to A. clam : upper surface dead golden, or dull 

 ochraceous, suffused with vinaceous greyish ; fringe deep grey ;
