10. P. consohrina Zett : 1 have caught or seen this species from at 



least Hampshire (New Forest), Lancashire (Silverdale), and 

 Haddington (Aberlady). Walker says "common on the 

 sea-coast (E. S. I.)-" Why Becker failed to recognise this 

 species from Zctterstedt's description I cannot tell, as Walker 

 and E-addatz found no difficulty ; it is however obviously the 

 same species as Lichtwardt described in 1896 as P. discolor 

 Zett., which had previously been described from the female 

 only ; whether Zctterstedt's P. discolor is distinct from his 

 P. consohrina 1 cannot say. 



11. P. micans Meig. : this species is difficult to place in a dichotomic 



table, because it has almost a spine on the middle coxae, the 

 face is so narrow that its colour is difficult to determine, and 

 even when determined is black about the middle but whitish 

 above and below% while the silveriness of the abdomen is 

 easily overlooked ; it is however the only species of Porphy- 

 rops which has an approximation to an erect black bristle on 

 the front of the hind coxae. I have taken it near Boxhill in 

 Surrey at I believe the shingly sides of the Hiver Mole, and 

 I have also taken it at Mailing near Lewes and at Henfield 

 in Sussex. I have also seen a male in the late Dr. P. B. 

 Mason's collection under the name of P. /w/y?/?es. Failing 

 to recognise it in 1876 I unfortunately redescribed it as 

 new, under the name of P. simplex. 



12. P. nasuta Fall. : there was a male in the late Dr. P. B. Mason's 



collection which was probably taken at Deal, and with it 

 was a fragment of a probable female. 



13. P. riparia Meig. : better known as P-iyrcerosa Lw., but described 



by me in this Magazine for February, 1876, as P. tenuis. I 

 have taken it at Dovedale, Millersdale, Arran, Kannoch, and 

 Tongue. 



14. P. penicillata Lw. : a male in the late Dr. P. B. Mason's col- 



lection dated May 16th, 1868 ; probably taken at Deal.

ON THE SCENTS OF THE MALES OF SOME COMMON ENGLISH 



BUTTERFLIES. 



BY G. B. LONGSTAFP, M.D., P.E S. 



Following up the preliminary observations of 1903, mentioned, by 

 Dr. F. A. Dixey at a recent Meeting of the Entomological Society 

 (Proceedings, 1904, p. Iviii), I, during August, 1904, examined for
