minated by three claws; the two superior ones are curved and pectinated, 
and the inferior one is inflected near its base. The palpi have a small, 
curved, pectinated claw at their extremity. Abdomen oviform, thickly 
covered with hairs, convex above, projecting over the base of the cephalo- 
thorax; upper part dark brown, with three minute tufts of yellowish 
hairs before; under part hoary, or pale yellowish brown. Sexual organs 
glossy, of a very dark brown colour, faintly tinged with red; connected 
with their anterior part is a large, straight process directed backwards ; 
it occupies a groove in the medial line, and is enlarged and depressed at 
its posterior extremity. 
The male, though rather smaller than the female, resembles her in the 
relative length of its legs, and in colour. Third and fourth joints of the 
palpi short, the latter being the larger ; fifth joint oval, convex and hairy 
externally, concave within, except at the extremity, which is compact 
and pointed, comprising the palpal organs; they are highly developed, 
complicated in structure, having a strong, pointed spine near the middle, 
directed downwards and outwards, and a fine, black, curved spine ori- 
ginating on the inner side, and passing obliquely under the former ; their 
colour is reddish brown. 
In the month of August, females of this species may bé seen among short 
grass and heath in pastures and on commons in Denbighshire and Caernar- 
vonshire, with their cocoons attached to their spinners. The cocoon is lenti- 
cular, measuring 3th of an inch in diameter, and is composed of pale brown, 
or dull greenish brown silk, of a compact texture, surrounded by a narrow 
whitish zone of a lighter texture; it contains about 25 spherical, yellow eggs, 
which are not agglutinated together. The young, when they quit the cocoon, 
mount on the back of the mother. 
On the 12th of September, 1838, a minute Ichneumon came out of a cocoon 
belonging to this species, which I had placed in a phial.
