M. formicarius, Li. (= formicalynz, Burm. et auct.) 
One example from Yokohama (Pryer), in Wormald’s 
collection. It is of large size (a 80 mm.), but 
differs in no way from European examples. The species 
is spread over the whole of Europe, and through Central 
and Northern Asia to Japan. I have it from East Siberia 
and North China.
