414 BRITISH ORIBATIDJ;. 



the progaster, and there are two longitudinal rows of 

 moderately large, curved, flexible hairs on the noto- 

 gaster. Genital and anal plates rather large, close 

 together in the central part of the ventral plate ; they 

 are nearly square, and the genital are slightly the 

 larger. 



This so closely resembles the adult that it is only 

 necessary to notice the differences ; it is usually either 

 entirely covered with white or grey powder, or has the 

 powder plentifully scattered over it. 



Colour dirty yellowish-white, rostrum and legs light 

 pinkish-red. 



Texture soft, dull in appearance ; it is really finely 

 reticulated ; this is best seen on the larval cast skin. 



Legs not quite so long nor so strongly moniliform 

 as those of the adult, otherwise very similar. 



Abdomen a trifle longer in shape than that of the 

 adult ; hairs on the notogaster longer and black. Geni- 

 tal and anal plates much smaller and more oval than 

 those of adult. 



Distribution. — Generally distributed, but not very 

 abundant. The small, very powdery specimens I have 

 chiefly found in Epping Forest. The species has been 

 recorded in France ( ? in Germany also), 



Canestrini and Berlese have described a species 

 which they call Belpa glohi'pes, it only differs from the 

 present species in having the hairs on the notogaster 

 larger and thicker ; I have myself seen such specimens 

 from Switzerland, it is difiicult to say whether it is 

 more than a local variety.
