492 BRITISH ORIBATIDiE. 



elevations of the posterior part of the cephalothorax ; 

 the pseudo-stigmata are situated on these elevations. 

 Between the two is a longitudinal sulcation extending 

 from the base of the cephalothorax to the commence- 

 ment of the sloping portion of the rostrum. Pseudo- 

 stigmata rather near together and rather small. 

 Pseudo-stigmatic organs long, curved (either back- 

 ward or forward), filiform, rather thick. Interlamel- 

 lar hairs much shorter, and rather thicker than, but 

 otherwise resembling, the pseudo-stigmatic organs. 

 Two smaller hairs of the same nature represent the 

 lamellar hairs [these are omitted in the plate]. E^ostral 

 hairs short and curved. Apodemata joined to the 

 sternum. 



Legs of medium length, stout ; the fourth pair pas- 

 sing the hind margin by about one half of the length 

 of the tarsi. Coxse of the two hind pairs of legs large 

 and globose, all the femora turned almost at right 

 angles before insertion into the coxae. The coxae of 

 the third and fourth pairs of legs are inserted into 

 almost tubular projections of the sternal plate. Each 

 joint, except the coxse and tarsi, bears a whorl of 

 short, curved, thick white hairs. The tarsi have the 

 usual fine hairs. Claws monodactyle. 



Abdomen almost a parallelogram, but the margins 

 are slightly curved. The lateral margins are formed 

 by broad raised bands, which stand at an angle of about 

 forty-five degrees near the progaster, but become 

 flatter near the posterior margin, where they widen 

 out and become almost merged in the general body 

 surface. These lateral bands are finely reticulated 

 (reticulation about the same as that of the cephalo- 

 thorax). The progaster is formed by a smaller raised 

 band similar to the lateral but narrower. Inside the 

 lateral bands the notogaster is arched, but it does not 

 attain any level higher than the outer edges of the 

 lateral bands. This central portion is much more 

 coarsely and irregularly reticulated than the bands ; 

 reticulations about sixty to the millimetre, pits four to
