12 



one-half, but less than three-quarters. iEdoeagus with small 

 rounded keel before the orifice. 



Ductus bursa 1 short; signum long, piriform. 



We are unable to detect any difference between the 

 female of this species and chrysantheana. 



Cnephasia communana, H-S. 2—1 



Mansbridge {Thurnall's Specimen), and J. W. M. 

 We confirm Barrett's opinion, Lep. J>. Isles, Vol. x., 

 p. 264, that these specimens are a distinct species, but 

 whether they are the communana of H.S. or not, we have 

 no means of ascertaining. 



Valva straight, bluntly rounded indent before sacculus; 

 sacculus almost three-quarters. Uncus minutely spined 

 narrows more quickly than preceding two species. 

 /Edoeagus with dentate ridge. 



Ostium triangular; ductus bursa 1 bulbed at either 

 side; signum piriform. 



Cnephasia virgaureana, Tr. 6—2 



Richards and Gardner. 



Valva with edges parallel, margin squared; sacculus 

 extended the length of the valva. /Edooagns stout, stumpy, 

 with serrate rounded keel before the apex. 



Ductus bursas very weak: signum evenly ph'iform. 



Cnephasia genital ana, Pierce and Metcalfe 3—3 

 R Adkin and J. W. M. 



Valva short, obtusely pointed; sacculus very long, strong, 

 extending beyond the valva, much curved. iEdceagus 

 slender, pointed; vesica evenly scobinate. 



Ductus bursa) geniculate, narrowed; signum long, 

 double row of teeth. 



Genus 2. Nephodesme, W>. type penziana, Thunberg. 

 The distinct modification of the uncal parts; the absence of 

 gnathos; the spined transtilla, warrant a separate genus 

 lor this group.
