 it differs mainly by this, that mesosternum in middle — line has a 

 very fine carina, that first joint of hind-tarsi is elongated, as 

 long as the following three joints together, where that of Tachinus 



is short, and that - (Page 3C3) — the three first joints 



of cfare not dilated. Abdominal sides and tip with robust, outstand- 

 ing bristle-hair. 



To this 1, widely distributed European species, which is also

In connection with the above mentioned, most outstanding generic 

 characters particularly identifiable by the color of elytra. 



Black, shining; sides of pronotum rather broadly, its fore- and

 is often less predominating than the black. 



Head and pronotum are without punctation, but the surface with 

 extremely fine transverse-aciculati ons, as well as elytra naked. The 

 heaa is broad; antennae slender, their third joint longer than the 

 second, the fourth and the following densely pubescent, the middle-
