ON BRITISH SPECIES OF EUPCECILIA. 91 



fully set off by the bright yellow fringe. As a rule it is the 

 larger species, though I have seen small examples in Mr. 

 Bond's collection. 



Centaurea grows commonly where the insect occurs, and 

 it is possible that tlie larva may feed on the seeds. 



Sp. 20. Degreyana, n. sp. 



E, cHiellw valde offinis, sed alls anticis paullo 

 angustioribus, colore plus rosaceo, ad apicem 

 minus saturate suffusoy Jimhria aurantiaca, 

 minus rufescente, posticis pallidioribus, capite 

 thoraceque pallidioribus mox distinguenda. 

 This insect is very closely allied to ciliellajand is of about 

 the same size, but seems to be sufficiently distinct. The 

 head and thorax are decidedly paler and clearer white ; the 

 anterior wings more elongate and narrower ; the dark central 

 fascia much narrower ; the ground colour with a rosy tinge, 

 which is wanting in ciliella, and generally paler, with- 

 out much evidence of the fuscous suffusion in the apical 

 portion so conspicuous in that species ; the fringes less red- 

 dish: the hind-wings decidedly paler. 



Taken by the Hon. T. De Grey, M.P., at Thetford, 

 Norfolk (and also at Wicken Fen), in a locality where no 

 species of Primula occurs. Examples sent to Herr Heine- 

 mann were returned as unknown, if it were not a variety 

 of ciliellay which, taking into consideration the differences 

 above noted, and the absence of the food plant of that insect 

 in the locality where they were found, I consider is little 

 likely to be the case, and I have consequently ventured to 

 apply to it the name of its captor. 



It is worthy of remark that one of Herrich-Schaffer's 

 three figures of dipsaceana (roseana) much resembles 

 Degreyana.
