GREASY OR MARSH FRITILLART. 137 



Li may be characterised negatively as not having the 

 rows of black spots found on both surfaces of Cinxia. 

 though its colouring is very similar -fulvous (or orange* 

 brown) and black above ; straw-coloured, fulvous, and 

 black beneath. 



The caterpillar is black, with rust-coloured spines; 

 and feeds on various species of plantain. 



The butterfly is out from May to July, and is met 

 with (if at all) on heaths, clearings in woods, &c. 

 Localities, in some of which it is very plentiful, are, 

 Caen Wood ; Coombe "Wood ; Epping ; Halton, Bucks ; 

 Bedford ; Aspley Wood, Beds ; Plymouth, Teignmouth, 

 Stowniarket, Dartmoor, Devonshire ; Oxford ; Wilt- 

 shire; Colchester; St. Osyth; Tenterden; Eaversham; 

 Deal; Canterbury. Very rare in north of England.

 distinct shades, some with pale lawny yellow, others with 

 orange brown. This latter tint forms a band parallel
