CVTIZiUS, Erichson.* 



This genus contains two or three species from Northern Asia, North 

 America, and Europe ; our single species is very widely distributed in the 

 northern and central parts of Europe, and in North America ; it closely 

 resembles a small Byrrhus, but may be known by its more or less 

 metallic appearance, the absence of ioveae on the first ventral segment of 

 hind body, and the free intermediate and posterior tarsi. 



* According to the catalogue of Heyden, Reitter, and Weise, this genus is synony- 

 mous with Cistela, Geotfroy.
