iiotum, but it has these very much larger, oceupyiug nearly the whole 

 surface, the mark ou the sternum is much larger, the pleurre beneath 

 the wings are marked with black, the thorax generally is not so deeply 

 ])uuctured, the incision in the clypeus is not so deep, the mouth is 

 dirty, not clear, white, the stigma is broadly black at the base, and the 

 3rd sub-marginal cellule is very much shorter, more so indeed than in any 

 species in the grou]), while the 2nd recurrent nervure is farther 

 removed from the 3rd sub-marginal : the nervui'es are darker, and the 

 legs not pale at the base. 



The antenniB are not much longer than the abdomen and meta- 

 thorax, the 3rd and 4th joints are of nearly equal length ; the last is 

 pale brown beneath. On the head, the orbits of the eyes, and the face 

 below the antennae are reddish-luteous, the clypeus sordid white ; the 

 mandibles dark piceous. Cenchri and blotch large, pale white. There 

 are two small dots ou the apex of the abdomen above, and two larger 

 ones on the 5th segment beneath. In the form of the abdomen, &c., 

 it agrees with the other species. 



I captured the above either on alder or birch, at the foot of Ben 

 Clibrick, Sutherlandshire, at the end of last month (June). The four 

 other species of this section were also met with in Sutherlandshire.
