ininated by tliree claws ; the two superior ones are curved and pectinated, 

 and tlie 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 céphalo- 

 thorax ; up])er part dark brown, with three minute tufts of yellowish 

 haiis 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 tiie 

 relative length of its legs, and in colour. Third and fourth joints of the 

 palpi sliort, 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, 

 complicate;! 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 be seen among short 

 grass and heath in pastures and on commons in Denbighshire and Caernar- 

 vonshire, with tlicir cocoons attached to their spinners. The cocoon is lenti- 

 cular, measuring ytli of an inch in diameter, and is composed of pale brown, 

 or dull greenisli brown silk, of a compact texture, surrounded by a narrow- 

 whitish zone of a ligliter texture ; it contains about 25 spherical, yellow eggs, 

 which are not agglutinated together. The young, when they quit tiie cocoon, 

 mount on the back of the mother. 



On the I'ith of September, 1838, a minute Ichneumon came out of a cocoon 

 belonging to this species, which I had placed in a phial.
