568 Mr. Cameronotes on Hymenoptera, 
more shining, and the band on base of abdomen. much 
wider. The saw is very different. 
Not common. Mull, Rannoch. 
10. Tenthredopsis picticeps, n. 8. 
Black; labrum, clypeus, orbits of eyes, a line on 
pronotum and scutellar spots, white, the third to sixth 
segments of abdomen all round, and the legs, bright red ; 
coxe black, largely white behind; trochanters white ; 
posterior femora black at base ; posterior tarsi fuscous 
at apex. Antenne longish, pale beneath. Wings hyaline; 
stigma white at base. Length 5 lin. 
Allied to ornatus, but it has the incision in clypeus 
not so deep, the eyes are marked with yellow all round, 
the antenne are longer, with the third joint not so 
long in proportion to the fourth, and the pleure are 
scarcely punctured ; ornatus, too, has the clypeus black. 
Rare.

14. Tenthredopsis lividiventris, n.s. 
Black; labrum, clypeus, mandibles, the orbits of eyes 
broadly, edge of pronotum, tegule, and scutellar spots,

with livid white; trochanters pale; hinder femora for 
the greater part black above; apex of hinder tibie and 
tarsi fuscous. Wings hyaline; stigma pale at base;

livid abdomen, and by the pale testaceous splashes on 
pleure and sternum.
