rugged as on the head ; abdomen smooth, shining, the basal segments 

 almost glabrous, and with a few minute blisters on the surface. Head 

 and pleurae densely covered with a grey pile ; mesonotum slightly 

 pilose, as is also the apical segments of the abdomen. $ and <.

Readily distinguished from the two preceding 

 species by the colour of the femora and cerci. D. 

 vestigialis agrees with it in having reddish femora ; 

 but the eyes are oblong, cerci black, while it has also 

 white markings on the abdomen. 



Rare, appearing end of May and early in June in 

 Clydesdale. 



Sweden is the only continental country from which 

 it has been recorded.
