 it broad, with pale ochreons edges and darker centres, partially filled up with 

 brown ; snbmarginal line wavy, whitish, followed by blackish markings ; the apex 

 and anal angle more or less tinged with brown ; all the lines blackish along costa. 



Hi luhvi iiys : with the marginal half tinged witli brown ; the outer edge of 

 central fascia black. 



Underside dingy ochreons ; the markings blackish ; no l)rown snftasion.

One (J from Pinetown, Natal. 



The only example is not in a good condition, and the description is necessarily 

 somewhat imperfect : but it may be recognised by the brown patches. 



Subfamily HYDRIOMENINAE. 



Ausorgia gen. nov. 



Allied to Cataclysme Hiib.; but veins 8, 9, 10, 11 are all stalked together from 

 before end of cell ; 6 and 7 together from the upper angle or very shortly stalked. 

 T3-pe : Ansorgia divergent sp. nov. 



31. Ansorgia divergens sp. nov. 



Foreioings : pale greyish white with a slight ochreons tinge ; basal patch 

 formed of three or four dark grey lines, strongly angled in cell, followed by a whitish

One f? from Port Alice, Uganda, (type) February 1897; two cJcJ from Lugula, 

 Usoga, December 1896 ; one S from Kiorbezi, Unyoro, January 1898 ; and three 

 S 6 from Masindi, November and December 1897 (Dr. Ansorge). 



In two examples veins and 7 of forewings are not stalked, but 7 rises close 

 before the upper angle of cell : in all cases the other 4 subcostals are stalked together, 

 and there is no areole.
