84 LEPIDOPTERA. 



Buckler found a good distinctive character in the black bristles 

 of this larva, those of Gorydon being light brown. 



Perhaps our most lovely butterfly. Extremely local ; 

 frequenting sheltered hollows and slopes of hills, of chalk or 

 allied formations, in Kent, Surrey, Sussex, Isle of Wight, and 

 near Winchester ; Dorset, abundant at Corfe Castle ; Glou- 

 cestershire, Wootton-under-Bdge, and near Bristol ; and in 

 Devonshire near Torquay, Sidmouth, and Seaton. Said to 

 ' have been formerly found on the downs at Newmarket ; if 

 so, it is there probably extinct. 



Plentiful in Central and Southern Europe, North Africa, 

 and Western Asia. 



[P. Dorylas, Hill. — In the Zoologist for 1863 the late 

 Mr. Henry Doubleday wrote as follows : — " In Lewin's 

 ''Papiliosof Great Britain," published in 1795, figures are 

 given of a Ljicccna, under the name of Hyacinthus, which 

 Lewin states he took in two successive years by the side of a 

 chalk hill near Dartford, in Kent. Ochsenheimer refers 

 these figures to L. Dorylas, S.V. The late J. F. Stephens, in 

 his " Illustrations," doubtingly gives Lewin's insect as distinct 

 from Adonis, and in his latest publication, the " Museum Cata- 

 logue," it stands as ' variety a ' of that species. I do not know 

 whether any of Lewin's specimens are now in existence, but 

 his figures most certainly represent the sexes of Lycccna 

 Dorylas, which is distinguished from Adonic by its paler 

 blue colour, slightly tinged with green, immaculate cilia, and 

 the absence of the two transverse ocelli at the base of the 

 superior wings beneath. Mr. Cooke, of Oxford Street, re- 

 cently detected two specimens of this species among a 

 number of ^lr?o)u.3 taken in England, which he had purchased. 

 One of these I have seen, and it is certainly L. Dorylas. and 

 now that attention has been drawn to it, the insect will 

 probably be met with in the coming summer." 



Mr. Doubleday's expectation was not realised. No further 

 specimens have been forthcoming, and there is little doubt
