172 ELLIS: LANCASHIRE AND CHESHIRE LEPIDOPTERA. 



Polyommatus argiolus, L. Azure Blue. 



Local, but usually common where it does occur. 



Lane. — Grange, common (W.G. and E.S.) ; Silverdale 

 (J.C.M.) j Hale, taken by Mr. Nixon (C.S.G.). 



Ches. — Delamere (N.C.); Eastham and Hooton, taken by 

 Mr. T. Harris (C.S.G.). 

 Polyommatus corydon, Poda. Chalk-hill Blue. 



Recorded from Silverdale (J.B.H.), and from Grange by the 

 Rev. F. O. Morris in his 'British Butterflies.' 

 Polyommatus icarus, Rott. = alexis, W.V. Common Blue. 



Very abundant on the coast sandhills, as at Crosby, Wallasey, 

 &c. Common about Grange and Silverdale (J.B.H. and 

 J. CM.). Common throughout AVirral, and in Delamere Forest, 

 but scarce near Cheadle-Hulme, from whence Mr. Corbett 

 reports having seen only about five specimens in seventeen 

 years. 



I have taken the variety icarinus. Scrib., on the sandhills, 

 where it is probably not rare. It differs from the type in having 

 the space between the central spot on the under side of the 

 fore-wing, and the base quite devoid of spots. 



Mr. Mosley figures (Varieties, Lycaena, pi. iii., f. 5) a fine variety 

 taken by himself at Fleetwood, and Mr. Thorpe records (Ent. , 

 iv., 132) a gynandromorphous specimen from Middleton. 

 Polyommatus astrarche, Bergstr. = medon, Esp. agestis, Hiibn. 

 Brown Argus. 



Common at Silverdale (S.L.M. and J. CM.) ; Grange (J.B.H.); 

 Chat Moss, local (R. S. Edieston, Zool., i., 112). 

 Polyommatus aegon, W.V. Silver-studded Blue. 



Very local, but usually common where it occurs. Chat Moss 

 (J.B.H. and J.C) ; Barton Moss (J.C); Alderley, very rare 

 (W. W. Key worth) ; Bidston Hill, abundant, but local (J.W.E.) ; 

 Delamere, common (J. CM. and A.O.W).
