HERMANNIA NANUS. 457 



the liind margin ; flattened, and gradually diminislied 

 in width toward the distal ends. Coxge of the two 

 front pairs turned almost at right angles to the femora. 

 Tarsi blunt-ended. There are thick, rod-like, curved 

 hairs arranged in whorls on the three central joints of 

 most legs, two similar largish hairs on the outside of 

 each coxa of the third pair, and two extra hairs of the 

 like nature on the outside of each femur of the second 

 pair of legs. There are the usual hairs on the tarsi, 

 which also bear some short thick hairs on the actual 

 end, which often appear like side-claws, and there are 

 some short laurel-leaf-shaped spines underneath this 

 joint, and one or two above. A high power is required 

 to see their form. 



Abdomen long, almost sac-shaped, having the 

 appearance at first of being nearly parallel-sided ; but 

 this is soon seen not to be so, although this shape is 

 approached much more closely than is usual in the 

 family. Sides almost vertical ; back very much arched 

 and raised. Progaster nearly straight, with rounded 

 corners. Hind margin rounded. Notogaster and 

 under- surface deeply and coarsely pitted, the spaces 

 between the pits usually rather wider than the diameter 

 of the pits ; the sizes of both, however, vary consider- 

 ably, the pits average about 75 or '80 to the millimetre. 

 The genital plates are almost round, and in the usual 

 place. The anal plates are very large, long-shaped, 

 but surrounded by an almost circular ring, and they 

 extend on to the actual hind margin. The notogaster 

 bears eight rather irregular rows of thick, white, rod- 

 like hairs, dii'ected backward ; and there are a few 

 round the hind margin.

This is so similar to the imago that it is not neces- 

 sary to describe it separately ; it could scarcely be 

 mistaken ; it is, however, rather less long in shape ; the
