Further Notes on British Orihatidse. By A. D. Michael. 13 



The legs of the first two pairs are set in deep clefts of the pro- 

 jecting lateral portions of the sternum ; they have a tendency to 

 set outward. The second and fourth are the principal joints, the 

 tarsi being short and thick. Each tibia bears a long tactile hair ; 

 the tarsi have numerous fine hairs, and the other joints, except 

 the coxae, mostly have a few longish, fine hairs, chiefly arranged in 

 whorls. 



The abdomen is a short ellipse, not far from a circle, and is very 

 slightly truncated posteriorly. This truncated portion bears 

 two pairs of short, fine hairs, the inner pair being the longest. 



I beheve I know the nymph of the species, but as I have not 

 actually bred it I refrain from describing it. 



The species is common and generally distributed.

The colour both of body and legs is dark brown, almost black ; 

 the whole dorsal surface is thickly sprinkled with raised dots. 

 These are irregular in shape, and in scattering on the cephalo- 

 thorax, but on the abdomen, which constitutes by far the larger 

 portion of the creature, they are more even in size and arrangement, 

 being closely packed, and more or less approaching round or 

 subsquare. Towards the lateral and hind margins of the abdomen 

 these dots form hues of dots radiating from the centre of the body, 

 along the front margin they are transverse in arrangement, and 

 in the centre they are irregular, or form labyrinthine lines. These 

 dots projecting make the edge, or any part seen against the light, 

 always appear rough. 



The shape of the creature is an elongated ellipse, being nearly 

 twice as long as broad. 



The cephalothorax is broad and rather large, but is greatly 

 overhung by the anterior margin of the abdomen, which hides a 

 large part of it. The extreme tip of the rostrum is small and 

 rounded, and bears a pair of hairs. From thence the cephalothorax 

 widens suddenly, and becomes much arched, and again widens 

 somewhat suddenly at the insertion of the first pair of legs. There 

 is a tectum very conspicuous, but short and narrow, and without 

 lateral wings, or rather the edges are thickened, slightly raised, 

 and then turned downward, giving an appearance of being 

 attached to the cephalothorax by their whole circumference.
