One curious example, in which the hyaline spots on the primaries 

 have either disappeared or been greatly reduced in size.

 p. 344, footnote. 



Neither the figure nor the description of Westwood's insect 

 correspond with this species, nor is there the slightest reason for 

 Mr. Trimen's supposition that the sides of the abdomen had 

 " probably become discoloured." The following comparison will, I 

 think, show that this view of the case will not account for the 

 differences between the two types : 



Oxynetra zambesiaca, "Westwood (not Abantis zambezina). 



" The fore wings are chalybeous black. 



"The head and body are black, the head with a large white 

 frontal spot, and two small ones between the eyes. The tippets 

 of the collar or prothorax are clothed with scarlet hairs, the tegulae 

 or wing-scales, together with a pair of dots in front of them, and 

 a second pair behind them at the sides of the disc, as well as the 

 narrow hind margin of the scutellum, white : the latter is followed 

 by a curved band of scarlet, the extremity of the abdomen being 

 of the same colour : the four middle segments of the abdomen are 

 luteous, \\ ith a narrow dark longitudinal line down the centre." 



Sapcea trimeni, Butler (Abantis zambezina, Trimen). 



The fore wings are peacock-green, black in the centre ; the 

 hyaline spots rather smaller than in "Westwood's species, and there 

 is usually a small extra one on inferno-median area. 



The hind wiDgs have the external area almost wholly metallic 

 Prussian blue (not chalybeous black). 



The palpi are almost wholly snow-white, like the frontal patch ; 

 there is a central transverse white line on the vertex, as well as 

 the two dots at the base of the antennae ; the pterygodes are 

 purplish black at base, with a large patch of white before the 

 terminal fringe, which is dull black ; there is also a double white 

 spot at the base of the front wings. 



As with Westwood's species there are two convergent tufts of 



carmine hairs, forming what he calls " a curved band of scarlet " at 



the back of the thorax, and the abdomen terminates in a tuft of 



the same colour, but here the resemblance ceases : the upper
