Dp. 20s 19S: 
This species is a widely spread one; it is known from 
Spain, France, Italy, Austria, Hungary, Saxony, Dalmatia, 
South Russia, Turkey, Turkestan and Japan. 
I have seen specimens from Central Europe, Caucasus 
and Japan. I consider Formicaleo nigricans Okamoto 
(Wiener Entom. Zeitung, p. 288, 1910), of which species 
I possess a specimen from Japan, to be identical with 
tetragrammicus. In a great number of specimens the dark 
spots along the R in the forewing are wanting.
