The following species have much in common but are 

 divisable into several genera. The common characteristics 

 are the divided saccus; the strong spine of the cornutus; 

 the absence of uncus; the flying socii, that is where the 

 socii terminate in a pair of chitinised, curved, slender hooks; 

 the generally well-developed sacculus; the bursa much 

 thickened often in folds and spined. 



GENUS 5. TYPE 



Valva long, narrow; sacculus rounded; transtilla produced 

 in long, fused arm; uncus absent; socii weak, broad, curved 

 inwardly. ^Edoeagus stout, orifice pointed; cornutus a 

 stout spine. 



Ovipositor narrow. Ductus bursao short; bursa spined. 



affinitana, Dgls. 22 



F. G. Whittle A. E. Atmore. 



Sacculus rounded, but produced outwards. Cornutus with 

 email bulb. 



Spines of bursa form a central star. 



manniana, F.v.R. 11

 udana female Gn. 



J. Gardner, A. E. Atmore. 



Sacculus evenly rounded; transtilla arms longer than in 

 affinitana. Cornutus strong, with large bulb. 

 Bursa irregularly spined. 



GENUS 6. TYPE 



atricapitana, Stphj. W. M. 4-2 



The development is too pronounced to be included in the 

 other genera. 



Valva pointed; sacculus broad, produced in a long brush 

 of spines; transtilla a central arm, tip curved; socii reduced 

 to two weakly chitinised lobes set with fine hairs. ^Edoeagus 

 geniculate; cornuti a band of short, thick spines.
