1910.] FROM NORTHERN RHODESIA. 71 



c? . Upperside. — Primaries dull black with a slight appearance 

 of iridescence toward margins, due to the presence of a few pale 

 blue scales ; three small hyaline spots below costa between cell- 

 end and apex ; a minute hyaline spot in area 3 below cell-end, 

 and below it in area 2 a narrow hyaline streak. 



Secondaries. Ground-colour as primaries, immaculate. 



Underside as upperside but paler ; in primaries a well-marked 

 rufous streak passes through cell-end ; in some individuals a 

 faint trace of same in secondaries.

 dusky. 



Type S in Hope Coll., Oxford : Petauke, Luangwa valley, 

 16.ii.05. Also two, Luangwa valley, ii. and vi. 



Sarangesa perpaupera Holl. 



Not rare in high plateau country of Northern Rhodesia and 

 in Katanga. 



Sarangesa hollandi Butler. 



This species, which seems exceedingly rare in collections and 

 very doubtfully referable to this genus, was by no means rare 

 in the valleys of the Lofu and Kalungwisi rivers, vii.-ix. It 

 frequents the outskirts of patches of dense forest. 



CEL^NORRHINUS INTERMIX! US. 



Celcenorrhinus intermixtus Auriv. Ent. Tidskr. xvii. p. 280 

 (1896). 



Celcenorrhinus opalinus Butler. 



Two individuals captured in forest on the high plateau south 

 of Lake Tanganyika, viii. 



Celcenorrhinus galenus Fabr. 

 A ubiquitous forest species. 



Abantis venosa Trim. 



A common species everywhere. Extreme dry specimens are of 

 a. golden-brown colour, losing all the white discal area and black 

 margin of the hind wing underside. 



A. plerotica Karsch * appears to represent an extreme wet 

 phase of this species. 



Abantis zambesiaca Westw. 



This species is ubiquitous and on the wing at all seasons. It 

 may often be taken in large numbers at damp mud. 



Abantis paradisea Butler. 



A common species in the wet season in the Luangwa valley 

 but rare on the plateau. It has much the same habits as the 

 preceding.
