of the tegumen longer than the right one. The left valva 
narrow, with a rounded tip ; the right valva broad, with 
an irregularly curved upper edge, an acute tip and a very 
undulate lower edge; processus basales as in pfeifferae, 
but the right one dilated at the base and the left one 
narrower.

This species, relegated by Hampson (1898) to the syn- 
onymy of pfeifferae, was recognized by Van Eecke (1929) 
as independent, although this latter author did not pub- 
lish any argument supporting his point of view. The fol- 
lowing notes are based on an examination of the male 
holotype of acuminata. 
The figure published by Snellen (1881) is excellent. The 
thorax of acuminata is not spotted by orange at the mid- 
dle as in pfeifferae, the forewing has no supradorsal orange 
streak, and the spot m 3 is narrower and pointed above. 
In the hind wing there is only a broad basal spot with 
an external tooth joined to it (= rudiment of a distal spot), 
but not two spots. Abdomen with six yellow abdominal 
girdles; Snellen described the female as having five such 
girdles. 
Male genitalia (fig. 3) : Uncus broad at the base, nar- 
rowed at the tip. The lateral appendages of the tegumen 
rather long, longer and narrower than in pfeifferae. The
