SERIC ORID.-E— SE RICO JUS. 6 1 



large cloudy triangular blotch lies across the apex and is 

 preceded by some geminated white costal dots ; cilia 

 brownish-white. Hind wings pale smoky brown ; cilia paler. 

 Female a little smaller and with narrower fore wing-s. 



Underside of the fore wings smoky brown, with obscurely 

 paler costal dots. Hind wings smoky white. 



Excessively variable and in permanent local forms. On the 

 slopes of sandy cliffs, and old sand-hills facing the sea, it 

 abounds in sheltered spots where the ground is covered 

 with moss, thyme, and other close herbage, appearing then 

 of various shades of rich red-brown with deeper markings ; 

 on hills of limestone and trap of a similar colour mixed 

 with specimens in which the red-brown has become suf- 

 fused and the dark markings scarcely visible ; on the other 

 hand in more level chalky and sandy places all shades of 

 olive brown and grey-brown with dull markings. 



On the wing in June, July and August. 



Larva apparently undescribed. Mr. W. H, B. Fletcher 

 obtained eggs and fed the resulting larva3 before hybernation 

 upon thyme (Thj/nius serpjjllum), but they do not appear to 

 have survived. I have on the other hand reared specimens 

 from larvae collected in the spring along with those of 

 Ettdcmis littoralis, on Staticc armeria, but these larvas were 

 unfortunately not noticed. Mr. A. Thurnall has also reared 

 it from a pupa spun up upon Teucrium scorodonia. Probably 

 it frequents various low-growing plants. 



Also an exceedingly lively species, starting up from among 

 herbage in its favourite localities in multitudes in the after- 

 noon, but less swift in its movements than the last species, and 

 less brilliant in its appearance. Flying naturally for some 

 time before sunset. Excessively abundant on the " Breck "' 

 sands of the Eastern Counties to Norfolk, on coast sands 

 elsewhere, and all over the chalk-hills, downs, and rough 

 fields in chalky districts throughout the South of England to
