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

 rounded keel before the orifice. 



Ductus bursae short; signum long, piriform. 



We are unable to detect any difference between the 

 female of this species and chrysantheana. 



Cnephasia communana, H-S. 21 



Mansbridye (ThurnaH's Specimen), and J. W. M. 

 We confirm Barrett's opinion, Lep. B. 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. 

 2Edoeagus with dentate ridge. 



Ostium triangular; ductus burs.T bulbed at either 

 side; signum piriform. 



. Cnephasia virgaureana, Tr. 62 



Richards and Gardner. 



Valva with edges parallel, margin squared; sacculus 

 extended the length of the valva. ^Edoeagns stout, stumpy, 

 with serrate rounded keel before the apex. 



Ductus bursjp very weak; signum evenly piriform. 



Cnephasia genital ana, Pierce and Metcalf. 3^3 

 R Adkin and J. W. M. 



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

 extending beyond the valva, much curved. ZEdoeagus 

 slender, pointed; vesica evenly scobinate. 



Ductus bursfe geniculate, narrowed; signum long, 

 double row of teeth. 



GENUS 2. Nephodesme, ffb. TYPE penziana, Thunberg. 

 The distinct modification of the uncal parts; the absence of 

 gnathos; the spined transtilla, warrant a separate genus 

 for this group.
