Rhopobota naevana, Hb. 1422 



W. Mansbridye. 



Vulva not curved, emarginate on costa and outer edge; 

 sacculus weak, point not reaching across the valva. Uncus 

 absent; socii in the form of an arum lily; labides long, 

 clavate, hairy. ^Edoeagus short; cornuti many, about 

 20-24 



Ovipositor flattened. Ostium weak; ductus bursse, 

 short, thickened; bursa strongly thickened before the neck. 

 Signa two, scobinate, one wider. 



Rhopobota geminana, St. IF. Mansbridge. 6 2 

 We can see no difference between this species and naevana. 



Rhopobota fractifasciana, Haw. 1 1 



Valva curved, emarginate on the costa; sacculus angulate, 

 not produced, deeply emarginate before cucullus. Uncus 

 absent; socii delicate, a pair of long arms set with a few 

 spines, labides long, rounded, curved. /Edceagus short, 

 dentate. 



Ovipositor flattened. Ostium ovate; bursa thickened 

 before the neck. Signa corniform, scobinate. 



Rhopobota vacciniana, Z. I 1 



Valva with sides parallel, geniculate on costa near base; 

 sacculus terminating in a point, centrally. Uncus absent; 

 socii delicate, a pair of long arms finely spined; labides 

 broad hairy. ^Edoeagus short. 



Ovipositor flattened. Ostium simple, ovate; bursa 

 thickened before the neck; signa two corniform, scobinate. 

 The genera containing the following species do not form a 

 natural group. It is quite possible they are not closely 

 connected and may prove to be off-shoots of other genera; 

 at the same time, the strong apical spine of the valva, 

 coupled with the form of the ostium place and the shape 

 of the signa suggest a natural affinity to the preceding 

 genera, so we include them here.
