STIGMONOTIDAi—DICHRORAMPHA. 255 



On the wiug in June and July. 



Larva apparently undescribed. Mr. A. Thurnall has 

 reared this species from the roots of yarrow (^Achillea mille- 

 folium) dug up in April. Mr. G. Elisha reared it with other 

 species from roots of tansy {Tanacetum vulgare) dug up in 

 the winter. 



The moth is specially attached to the common yarrow, 

 sitting among it and flying about it with great constancy in 

 those places in which it is allowed to grow and spread into 

 large clamps, as, for instance, in some of the cemeteries i\\ 

 the suburbs of London, and on railway banks. In such 

 spots it is often to be found in abundance. It is easily dis- 

 turbed, flying away to another patch of the same plant in the 

 sunshine, but late in the afternoon flies of its own accord. 

 Rather a local species, yet to be found in all the English 

 southern counties to Oxfordshire and Herts ; also in the 

 eastern counties to Norfolk, and in Herefordshire, Gloucester- 

 shire, and Leicestershire. In Wales I have found it in 

 Pembrokeshire ; but this is, so far as I know, the extent of 

 its distribution in these islands. Abroad it is found in 

 Germany, Austria, and Hungary.
