Rhopobota naevana, Hb. 14 -22 



11'. Man8bridge. 



Valva no! curved emarginate on coata and outer edge; 

 sacculus weak, point nut reaching across the valva. Uncus 



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

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

 20-21 



Ovipositor flattened. Ostium weak; ductus bursa?, 

 short, thickened; bursa strongly thickened before the neck. 

 Siffna two. scobinate, one wider. 



Rhopobota geminana, St. 11'. Mansbridge. 5—2 



We can see no difference between this species and naevaun. 



Rhopobota iractifasciana, 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. .Edu-agus short, 



dentate. 



Ovipositor flattened. Ostium ovate; bursa thickened 

 before the neck. Signa corniform, scobinate. 



Rhopobota vacciniana, Z. 1 — 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. .Edeoagus 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.
