372 BRITISH ORIBATID^. 



Average length of legs (third pah') about '36 mm. 

 Average length of legs (fourth pair) about '42 mm. 



This is a particularly active species. 



Colour rather yellowish-brown of a medium shade, 

 almost even over the whole creature. 



Texture pohshed^ but finely punctured ; punctures 

 about 120 to the millimetre. 



Cephalothorax conical, with a shghtly rounded and 

 trifid rostrum ; the central portion of the cephalothorax 

 is considerably arched, leaving a depressed lateral 

 shelf at the hinder part which supports the first pair 

 of legs. The raised portion of the cephalothorax is 

 slightly constricted where it joins the abdomen, and in 

 the central part of the juncture are about five very 

 short radiating lines ; there are not any other mark- 

 ings on the cephalothorax. Rostral hairs thick ; the 

 palpi show slightly at the side of the rostrum and are 

 well provided with hairs. Pseudo-stigmata at the very 

 base of the cephalothorax, almost under the edge of 

 the abdomen. Pseudo-stigmatic organs very shorty 

 with obtusely 'pyriform clubs on short and slender 

 j^edimcles. Interlamellar hairs long and setiform, much 

 longer than the pseudo-stigmatic organs, slightly ser- 

 rated. Tectopedia large; first apodemata not joined 

 to sternum. Lamella very short, slightly raised, nearly 

 straight blades, nearer together at their distal than at 

 their proximal ends. Lamellar hairs longish, slightly 

 Serrated. 



Legs longish ; femora powerful, tibiae and tarsi fine 

 and attenuated; the fourth pair of legs project con- 

 siderably behind the body when stretched out. The 

 tactile hair is present on each tibia, and is very long 

 on the first leg ; the other joints, except the coxa and 

 tarsus, bear whorls of fine curved hairs, mostly set 

 rather nearer the proximal than the distal end. The 

 tarsi, as usual, are thickly set with fine hairs. Claivs 

 tridactyle almost homodactyle. 

 Abdomen elongated, oval; with rounded, and very
