piceous ; legs black, with the knees, and the extremity of all the 
joints of the tarsi, rufescent. 
Abdomen punctured, with the first segment having on each 
side towards the margin a triangular spot, and the second and 
third a transverse mark of a bright yellow, the margin of the 
fourth and of the fifth piceous. 
The ¢$ differs in having the last joint of the antenne inserted 
rather obliquely in the preceding one, and being narrower; the 
face and clypeus covered with a silvery down; the collar, 
tubercles, and scutellum, wanting the yellow marks, and the 
fourth segment having on each side a small yellow transverse 
line. 
In the Cabinets of Mr. Westwood, Mr. 
F. Smith, and in my own. 
+4+ I expect the yellow markings of the thorax are 
variable, for I have a specimen of a ¢ with a central spot 
on the collar; but this can only be determined by a multi- 
tude of specimens, and it is a rather rare species; it is very 
distinct from the preceding in form, and is besides smaller. 
The only place where I take it is Highgate, upon the leaves 
of brambles, where it alights for a moment, turns itself 
briskly round, and flies off again. On the wing it is easily 
taken, but when settling it is rather difficult to be secured, 
as like Hedychrum, Anobium, and other insects, it mimics 
death upon the least alarm, and falls down amongst the 
foliage.
