Ernestia.

Geographical distribution: — Northern and middle Europe 

 down into Styria; towards the north to southern Sweden. 



Remarks: My specimens are determined in accordance with 

 specimens named by Dr. Villeneuve ; I am in doiibt with regard to 

 Brauer's statements 1. c. as they seem to me not well answering to 

 the present species, f. inst. as regards the breadth of the frons and 

 fifth sternite in the male; there is no doubt that the species described 

 here is distinct from radiciim.
