turionana, Hb. J. W. M. 



Valva very similar to posticana, but much larger. Uncus 

 with a tendency to become double pointed, rudimentary 

 hairy; socii long, drooping, irregularly edged. JEdneagus 

 cardinate; cornuti deciduous. 13-15. 



The female organs are very similar to posticana. 



VIII. EPHIPPIPHORIDII. 



A rather mixed group from a male genitalic point of view, 

 but closely connected in the female, which has the two 

 signa corniform. In the general plan of the male organs 

 the valvae are somewhat long and narrow, indent beyond 

 the 3acculus, often there are ninth segment coremata 

 beautifully developed. The cornuti are broad, flattened and 

 deciduous. 



Genus 1. Rhopobota, Led. type naevana, Hb. 



Under the genus Steganoptycha, Stainton appears to have 

 soon the close relationship of the members of this little genus, 

 which subsequent writers have seen fit to divide. There is 

 nothing in the genitalia of either male or female to place 

 it here, nor in fact in any other existing group of 

 British Tortrices, although the general characters are not 

 such as to exclude it from this group. The highly developed 

 iabides find parallel in some of the Geometrid genera. 

 Unfortunately, the genitalia do not confirm the distinctive- 

 ness of two of the species ycminana and naevana. 



Rhopobota ustomaculana, Curt. 1—1 



Valva long, curved, emarginnte on the eosta; sacculus 

 terminating in n long point which reaches across the valva. 

 Uncus absent; socii cygnate; Iabides long, tapered, hairy. 

 yTCdceagus short; cornuti deciduous, eight. 



Ovipositor flattened. Ostium constricted behind: 

 ductus bursa- short, thickened; bursa strongly thickened 

 before the neck; signa two, small, curved, scobinule,
