This large, pilose species is at once recognised among the Danish 

 species. It bears some resemblance to L. flava L. which is not found 

 in Denmark, but this species has the abdomen densely reddish yeliow 

 haired. 



L. ephippiiim is not common in Denmark but has yet been taken 

 in several localities; Tyvekrogen, at Hørsholm and Ringsted; in Jut- 

 land at Vejle, Skanderborg, Frijsenborg, Gjessø near Silkeborg, Silke- 

 borg and Skjørping. My dates are ^le—'^^h. It occurs in woods, 

 especially in districts with pine-trees, and is generally found sitting on 

 the stems. 



Geographical distribution: — Northern and middle Europe down 

 into France; towards the north to middle Scandinavia; it is not found 

 in Britain. In middle Europe it goes high up in the mountains.
