 Several authors appear to have confused this species with Ptyelus 

 spumarius, Lin., var. 1, to which it bears some slight external resem- 

 blance. The synonymy is therefore difficult, and many of the citations 

 commonly given must be viewed with caution. The insect is common 

 upon various trees, but especially affects the Alnus glutinosa, Lin. It 

 occurs throughout Europe, even in the south.

I have never taken this species, but some individuals are ia my 

 father's and Mr. Douglas's collections. It is found on the continent 

 upon willows, and is widely distributed, although nowhere common.

This grou]i is very limited in extent, and is characterized by having 

 the tibiae devoid of spines. The head is broader than the pronotum, and 

 the vertex, instead of being angularly produced, is rounded in front, 

 biconcave between the eyes, and faintly emarginate in the middle of its 

 antei'ior edge. Eyes very large, projecting on either side of the head. 

 Ocelli placed near the posterior edge of the vertex, and capable of being 

 covered by the pronotum. Pronotum transverse, medially carinated, 

 and with a semi-annular or horse-shoe-shaped depression on each side. 

 Hemelytra oval, longer than the abdomen, conchiform when closed, de- 

 pressed near the scutellum, and deflexed laterally ; the nervures coarse 

 and prominent, with large pentagonal punctures between. Wings 

 none. Abdomen short, pointed. Hinder legs scarcely longer than the 

 others. Our only species is —
