HERMANNIA NODOSA. 453 



pseudo-stigmatic organs. Tectopedia almost obsolete. 

 Apodemata strong and joined to the sternum ; those 

 in front of the fourth legs show a trace of the double 

 structure united by tabs described in H. jncea. 



Legs rough, rather thick and heavy, particularly the 

 two front pairs. The two hind pairs are set on pro- 

 jections of the ventral and lateral surfaces of the body, 

 which, however, are not so large as the same parts in 

 H. picea, and the legs are longer than in that species. 

 The joints diminish in thickness from the femur 

 onward. The genuals are longer than usual. The 

 tibiae of the two front pairs of legs scarcely, if at all, 

 longer than the genuals, those of the two hinder pairs 

 about half as long again. Tarsi long, the two front 

 pairs with a very slight elevation about one quarter 

 the distance from the anterior ends, carrying a secon- 

 dary tactile-hair. Claws very strong. Tactile hairs 

 on the first pair of legs moderately long, on the other 

 pairs very short or obsolete. There is a whorl of 

 spatulate hairs on each of the three central joints of 

 each leg, the inner hairs of the whorl being absent on 

 the third and fourth legs, a similar hair on each coxa 

 of the third pair, and a strong, curved, similar hair 

 near the proximal end of each femur of the first two 

 pairs. These various hairs are very spatulate when 

 seen from the side with a high power. 



Abdomen sharply divided from the cephalothorax 

 and elevated above it ; it is elliptical, longer in form 

 than that of H. picea, or perhaps I should say than the 

 ordinary specimens of that species ; it is much arched, 

 and is covered with irregularly- scattered raised dots, 

 the distance between which and their whole arrange- 

 ment varies so much that it is not possible to give any 

 estimate of distance between them ; they are generally 

 probably a trifle smaller than those of H. picea, and 

 are often simply scattered in the same manner. A 

 specimen of this nature was selected for the plate in 

 order that it might not be supposed that it could be dis- 

 tinguished from H. picea by the arrangement of these
