TRIFID.E. 373 



In Wales it is recorded from Llangollen, and also in Flint- 

 shire, and in South Wales a single specimen was taken 

 about 1862 in the neighbourhood of Saundersfoot, Pem-

 Abroad it is found throughout Central Europe, and in South 

 Sweden, Denmark, Northern Italy, and Corsica.

 parallel duplicate, a line of clear ground colour lying between ; 

 the second line is an interspace or stripe of ground colour, 

 edging on its inner side a broad, cloudy, purple-brown 

 irregular band, which occupies much of the middle area of
