Conn) (Ixxxiv, lxxxv 
Mr, 8. A. Neve exhibited a number of Lepidoptera selected 
from the collection made by him in N.-E. Rhodesia, in 1904 
and 1905, comprising the following rare and remarkable 
species :— 
Melanitis ibya, Distant ; Liptena homeyeri, Dewitz; Pentila 
peucetia, Hew. ; Catochrysops gigantea, Trim. ; Crenis pechueli, 
Dewitz, and Crenis rosa, Hew., which are evidently two distinct 
species ; and Crenidomimas concordia, Hopff., the mimic of 
the last two species. Also two remarkable species of the 
genus Aphnxus—including a female, so rarely taken in this 
genus—Acrexa natalica, Boisd., and Acrxa anemosa, Hew., with 
two remarkable moths showing a close mimetic resemblance 
to them. 
The exhibitor further stated that his collection would, he 
thought, prove exceedingly interesting as regards seasonal 
forms especially in the Acreinze and Pierinz, of which he 
showed examples. 
(a) Acrxa acrita, Hew.—Dry, intermediate and wet phases 
of both sexes ; the wet-season specimens were highly remark- 
able, being, especially in the females, nearly black. 
(6) Acrxa cheribula, Oberth., taken in the height of the dry 
season ; remarking that :— 
“Dr. Butler * has suggested that cheribula with its heavy 
black apex may be the wet-season form of aervéa. The speci- 
mens shown seemed to demonstrate fairly certainly that this 
is not the case. At the same time, an examination of the 
series in the British Museum left it doubtful whether the 
specimens there recorded by him under that name are the 
true cheribula of Oberthiir. They appear to be only varia- 
tions of acrita which, apart from its seasonal phases, is 
undoubtedly a highly variable species.” 
(c) Acrea natalica, Boisd.—Dry and wet phases of both sexes ; 
the dry specimens being characterized by their smaller size 
and slightly brighter colour.
