Genus 2. Bracta, Steph. type lanceolana, Hb. 



A difficult genus to place, having only two species to 

 consider. The valva and scobinate signum show a close 

 connection with the previous genera, but the very highly 

 developed uncus seems to suggest a further removal. 



Bracta lanceolana, Hb. W. Mansbridge. 10—3 



Valva short, spined on the outer margin; sacculus angular, 

 with deep depression set with fine hairs and containing a 

 small patch of strong spines. Uncus produced, tapered, set 

 at either side with a regular row of short blunt spines; socii 

 rounded, drooping. iEdceagus short, curved, simple. 



Ovipositor flattened. Ostium simple, with lip; signum 

 round, scobinate. 



Although specimens of this species vary considerably in 

 size, there is no appreciable difference in size of the 

 genitalia. 



Bracta fur Fur ana, Haw. 2—1 



Valva short, thinly spined on the outer margin; sacculus 

 rounded, with deep depression clothed with short, fine spines 

 containing a patch of strong spines. Uncus produced, set 

 at either side with a comb of short, blunt spines. 



Ovipositor flattened Ostium small, simple. Signum 

 rounded, scobinate. 



Genus 3. Apotomis, Hb. type corticana, Hb. 



The apparently natural group of species usually included in 

 the genus Argyroploce divides up into genera by the 

 genitalia, not quite in accordance with the wing markings; 

 and what have hitherto been considered close affinities in 

 the genus Argyroploce are by no means so closely related 

 and are found to divide into quite separate genera. 

 Valva long, almost clavate; sacculus extended in a round 

 lobe set with strong spines. Uncus flattened, weakly set
