262 LEPIDOP TEN A . 



clown the middle of the face ; dorsal and anal plates very 

 pale yellow, hardly distinguishable. 



February till April, and a second generation in July, on 

 Chrysanthcmnm leucanthemum (ox-eye daisy), feeding in the 

 lower, thick portion of the stem, burrowing passages under 

 the skin, and finally eating into the pith in the middle. 

 Assuming the pupa state in the burrow. 



This pretty little species is of rather quiet secluded habits, 

 and is most noticed in the second generation, probably 

 because so few species are then out ; it seems almost re- 

 stricted to chalk, limestone, and green-sand districts, and is 

 not in these very conspicuous ; the male flies a little in the 

 late afternoon sunshine, but the female keeps much con- 

 cealed among the food plant. Recorded in all the southern 

 counties from Kent to Cornwall, Somerset and Gloucester- 

 shire ; also in Essex, Cambs, Herts, Oxfordshire, Hunts, 

 Herefordshire, North Lancashire and Durham ; and in 

 Wales very abundant in Pembrokeshire. In Scotland in 

 East Lothian, Fife, Ayr, Renfrew, and Argyle with Arrau. 

 In Ireland at Howth, Athlone, Sligo and Connemara. 

 Abroad in Central Europe, Italy, Sweden, Finland, Livonia, 

 and in Asia Minor.
