This beautiful genus has but slender claims to be 
admitted into our lists, but the three records of its capture 
are all well authenticated, so that it can scarcely be 
omitted. It may be known from all its allies by its scarlet 
and greenish-black colours, its smooth, highly-polished head 
and thorax, dull flat scutellum, largely incrassated front 
femora, denticulated beneath, and the angulately produced 
apices of the front tibiz ; tarsi three-jointed. 
P. guttula, fub.—Head, pronotum, scutellum, and 
abdomen greenish black, legs and elytra scarlet, antennz 
pitchy brown. Head and thorax highly polished, with long 
scattered hairs, the latter punctured and impressed near 
the base, longer than wide, sides slightly rounded, diverg- 
ing to the posterior angles; scutellum and elytra dull. 
Only the undeveloped form has been taken in this country, 
in which the elytra are truncate posteriorly, the membrane 
very short and transverse, not quite reaching to the apex 
of the second abdominal segment; abdomen punctured, 
In the developed form the elytra reach to the apex of the 
abdomen; the apex of the corium is black, the membrane 
greyish black, with a white spot on each side below the 
apex of the corium, 
L. 9 mm. 
One specimen taken at Chariton, Kent, by Mr. K. W. 
Janson, which is now in my collection; one recorded by 
Curtis, from the sandhills near Sandwich, taken by Mr. A. 
Kennedy, in September, 1837; and one taken in recent 
years by Mr. Sidebotham.
