MEMBRA CiDJ$. 
two small tubercles like shining pearls are seen above the true eyes; the tegmina are 
long, hyaline, but greyer towards their bases; neuration brown and fine. 
Canon Fowler remarks, this species may be known by its large size, by the 
glabrous disc of the pronotum, and by the nearly straight spines of the posterior 
process. 
My figure is from a broken specimen from the Salle Collection, and it wants the 
abdomen and the legs. It does not, however, seem to be that noticed by Fowler, as 
the suprahumeral horns are intact, as shown in my drawing. It also somewhat 
differs from the brief description given by Fairmaire. It is allied to P. affinis. 
Size, 9x4 mm.

Pronotum compressed, sub-arcuate, posterior end acute; suprahumerals prolonged 
into horns more or less long. Tegmina transparent, with the areas rhomboidal in 
shape ; the last apical area stylate. 
A rather numerous group composed of forty or more species, some of which 
inhabit districts ranging from Nova Scotia to Buenos Ayres. 
Some species like Ceresa bubatus , attack the plants and crops of the agriculturalist 
and are said much to injure the potatoe.
