96 TENTHHEDO PUNCTULATA. 



black on the posterior tarsi being continuous, while 

 the other two species have the joints annulated. 



A very common species in the north, but does not 

 seem to occur farther south than the midland counties 

 of England. In Scotland I usually capture it on birch, 

 and have taken it at an elevation of upwards of 2000 

 feet. 



It is met with in the middle and south of Sweden, 

 in Silesia, Austria, and France. 



SECTION 2. Mesonotum smooth, unpunctured. Humeral 

 cellule in hind ivings appendiculated. . Cheeks distinct. 



Green, marked witli black. Antennae long, thin, lined with black 

 above. Clypeus deeply emarginated. Stigma green or pale. 

 Legs lined with black above. (Species 20 22).

Green; antenna on the upper side, the sutures on vertex; sutures 

 of the head behind ; sutures of mesonotum and pleurae ; a row of small 

 dots (two to each segment) along the edge of the abdomen above, the

 joints of the tarsi at their apices, as well as the apex of posterior tibiae

Length 4^ 5^ lines. 



Ab. Apical half of the abdomen blackish above. 



Easily known from viridis by the greenish abdomen 

 with the black lateral spots, the smaller black marks 

 on the head and mesonotum, less projecting front and 

 thinner antennae. 



The larva, according to Kaltenbach, is 8 10'" long,
