from the West, I feel no certainty of the specific identity of the 

 two insects. 



136. J^GOCERA TRICOLOR. 



JEgocera tricolor, Druce, Ent. Month. Mag. vol. xx. p. 155 

 (1883). 



Samburu, 10th & 15th November, 1896 ; between Voi and Ndi, 

 22nd May, 1897. 



The last example obtained is of interest on account of the 

 distortion of the subapical patch across the right primary. It 

 seems to me not at all unlikely that this may prove to be only a 

 form of &. leucomelas with orange secondaries ; a similar variation 

 in colouring occurs in the very closely related 2E. trimeni and in 

 ^E. triplagiata. 



137. EUPLEXIA OPPOSITA. 



Mamestra opposite Walker, Cat. Lep. Het. xxxii. p. 667 (1865).

Amyna selenampTia, Guenee, Noct. i. p. 406 (1852). 

 Samburu, 28th October, 1896. 



One rather rubbed example of this abundant species was 

 obtained.

 January, 1897.

General pattern of both sexes similar to that of T. tropica ;

 and transversely banded with plumbeous grey, varied with 

 olivaceous ; a black spot at end of cell, but none in the cell, the 

 pale area terminating beyond the cell in the usual pale-edged 

 blackish olivaceous 3~ sna P e d character impinging upon the ex- 

 ternal third, which is glistening sepia-brown ; the external border 

 faintly indicated excepting at the extremity of the median areoles 

 and at the external angle, where it becomes whitish ; the two 

 patches connected internally by a zigzag whitish line ; a marginal 

 series of black dots, barely visible excepting upon the pale patches : 

 secondaries silky smoke-brown, a little darker on outer border and
