Of this species we only possess Walker's rather imperfect type 

 from Natal ; it is, therefore, a welcome addition. 



The genus Lexis is allied to Sozuza, although the pattern of 

 L. bi^mnctigera 5 reminds one rather forcibly of that of (Eonistis 

 quadra $ (to which it is certainly not closely related). It is 

 characterized as distinct from Sozuza by the absence of the post- 

 discoidal areole (or false cell) in the primaries, by the much greater 

 length of the costal vein, with which the first subcostal branch 

 anastomoses ; the third and fourth branches emitted as in Sozuza, 

 but the fifth branch emitted from the fourth instead of from 

 before the emission of the third. In the secondaries the so-called 

 second and third median branches (now recognized as the second 

 median and lower radial) form a much shoi'ter furca than in 

 Sozuza.

We only have a single female of this species in the Museum 

 collection ; the present male does not seem to differ more from it 

 than the sex would account for ; but, as the type of L. fallax \\a,s,
