418 BRITISH ORIBATID^. 



coxse of tlie first two pairs are very small, and the 

 femora of these legs are turned almost at a right angle 

 at their proximal insertion. The coxge of the two 

 hinder pairs are much larger, curved, and clavate. 

 There are two large curved hairs on each coxa of the 

 third pair ; one on the thin proximal part, and two 

 whorls on the distal part of each femur of the first 

 two pairs, and one whorl on each other joint of each 

 leg except the coxse ; all these hairs are sUghthj ser- 

 rated or imhricated ; there are also some fine straight 

 hairs on the tarsi. The tactile hairs are not strongly 

 developed. 



Abdomen, as seen from the dorsal aspect, appears 

 almost globular ; the progaster is rounded, forming an 

 unbroken curve with the rest of the periphery. The 

 notogaster is without markings ; it bears a row of 

 about eight strong, curved, black hairs on each side, 

 rather nearer the lateral edge than the median line; 

 there is also a pair of similar hairs on the hind margin. 

 All these hairs are slightly imbricated. There is a 

 small blunt projection in front of the insertion of each 

 third coxa, and a larger one to the anterior angle of 

 which this coxa is articulated. When the creature has 

 lately emerged it sometimes carries the cast skins in a 

 small shrunken lump on the notogaster. 



Nym]ph. 



This is a pretty and distinct creature, more clearly 

 different from the immature stages of other species of 

 the genus except D. te^mipes, than the adult is from 

 some of the other images. The nymph has a certain 

 resemblance to that of Notaspis hipilis. 



Colour very light flaxen, or yellow-brown ; rostrum 

 and legs pinkish. 



Texture highly polished, semi-transparent. 



Shape longish-pyriform, with a bifid, posterior, 

 central point. 



Cephalothorax. — Rostrum small, the point slightly
