TENTHREDO RUFIVENTRIS. 81 



tibiae and tarsi, the anterior tibiae behind, and the joints of the tarsi in 



Sart black ; anterior tibiae and tarsi livid white in front. Wings short, 

 yaline; costa and stigma black. Vertex and abdomen shining; 

 mesonotum opaque, punctured ; vertex finely punctured, shortly pilose. 

 Mandibles brownish at apex. 



The 3 has the abdomen from the third segment red ; the whole of 

 the femora and the four anterior tibiae and tarsi are broadly lined with 

 black above. The antennae have all the apical joints black on the upper 

 side. 

 Length 4 5 lines. 



Ab. Nigro-lineata, Cam. All the femora and the four 

 anterior tibise and tarsi broadly lined on the upper 

 surface with black. 9 and 3 . 



The amount of black on the legs and of white on 

 the antennae varies a good deal. 



The black body, reddish legs, and single white spot 

 over the posterior coxae, will serve to distinguish this 

 species, which is tolerably common in Scotland, from 

 the south to Sutherlandshire, but seems not to be so 

 common in England, where, according to Stephens, it 

 has been taken in Birch Wood. 



The species does not apparently inhabit Scandinavia, 

 but is met with in Germany, Holland, Switzerland, 

 and Italy. 



Antennae short, fifth, sixth, and seventh joints more or less 

 white. Eyes and pronotum marked with white. No white mark 

 over posterior coxae. Pleurae finely tuberculated, pilose. Eyes 

 small, not touching clypeus. Legs red, femora lined with black. 

 Abdomen shining, bronzy, mostly reddish (Species 7 and 8).
