New British Oribatidse. By A. D. Michael 395 



named bosses bear the pseudo-stigmata, which are very projecting 

 and nearly upright. Pseudo-stigniatic organs rod-hke. Kostral 

 hairs sharply curved, thick ; lamellar hairs similar, larger. Legs 

 long and thin, of the typical Bamseus form, but neither the 

 whole leg nor the peduncles of the individual joints are as long or 

 thin as in D. clavipes, D. tenuipes, &c. An irregular whorl of 

 thick, sharply- curved hairs on each joint except coxae and tarsi. 

 Each tarsus has a large spike near its proximal end, in the upper 

 median line. 



Abdomen globose, very finely punctured. Dorsal plate very 

 much bent down and under, so as to form part of the ventral sur- 

 face, especially posteriorly ; ventral plate consequently very small, 

 A small projection each side between the third and fourth legs, 

 and a row of brown spike-like hairs round the hind part of the 

 margin. 



This creature was discovered by Mr. E. Bostock at Stone, 

 Staffordshire. I have since found a single specimen at Keswick, 

 Cumberland.

A species marked by the form of the pseudo-stigmatic organs 

 and by the long legs. 



Colour brown, of medium depth, with a slight purple bloom. 

 Creature usually dusted with white powder. Texture of cephalo- 

 thorax roughish, of abdomen smooth, but not polished. 



Cephalothorax considerably narrower than abdomen ; rising to 

 broad elevations opposite the insertions of the first and second legs, 

 leaving a strong depression between. Central part of cephalo- 

 thorax raised and arched, there is a sharp depression before the 

 abdomen. Kostrum small, pyramidal. Two pairs of rostral 

 hairs. The elevation opposite the first leg has a small projection 

 to which the leg is articulated. There is a much larger projection 

 to the posterior edge of which the second leg is articulated ; it is 

 rounded and without any anterior point. There is a smaller pro- 

 jection with a curved anterior point behind the second leg. Pseudo- 

 stigmata much raised, near together. Pseudo-stigmatic organs 

 rather short, with rod-like peduncles of even thickness throughout, 

 heads suddenly increased in thickness and continuing of the 

 increased diameter until near the point ; so that the organs have
