Archipsidii : Signum a single smooth horn with bulbed

By means of our investigations we have had the pleasure 



of adding some new species to the British list, viz. : — 



Cnephasia genitalana, E.M.M. Vol. 51, 1915, p. 8. 



Eudemis pomedaxana, E.M.M , Vol. 51, 1915, p. 9. 



Lipoptycha aratana, E.M.M., Vol. 51, 1915, p. 10. 



dft®) ■** iq.-i-^HJ: Lipoptycha torrana, a species still awaiting description. 



^tk?>fLMfB^.Peronea fissurana, E.M.M., Vol. 51, 1915, p. 327. 



Astatia simiana, which has hitherto been considered 



merely a variety of A. solaudriana. 



Epiblema littoralana, E.M.M., Vol. 51, 1915, p. 327. 



On the other hand, we can find no difference from a 



genitalic point of view, between the following pairs of 



species : — 



Argyroplocc carbonana ?nd .1. nigricostana. 



Argrotoxa schallcriana and .!. pcrplexana. 



Celypa striana and C. pur pur ana. 



Spilonota ocellana and S. lariciana. 



Rhopobota ncrvana and R. geminana. 



In view however of the minute differences, which none 



the less when detected, are found to be constant, separating 



other pairs of species; and in the face ef the apparently 



great and constant differences in the wing markings of the 



above pairs, we do not feel able to pronounce positively 



upon their identity.
