TERRESTRIAL ACARI OF 'JIIE TYNE PROVINCE 73 



Linked with the two preceding by the uniform shape 

 and distribution of the dorsal setae ; except the 

 frontal pair which are slenderly clavate, all are 

 acute and spinous, curved and appressed, three 

 series on each side of the dorsal scutum and one 

 marginal on the nude body — all of the same size 

 except one on each shoulder which is larger. 

 Process of epistome with lamellar base as in 

 marginahts. Genital and ventral scuta contiguous. 



120. Macrocheles longispinosus, Kr. 66, 67. 



Similar to the next following species in the sub- 

 circular form of the body and finer texture of the 

 dorsal scutum. Marginal setae very slightly 

 clavate, longer and more patent than in lougulus. 



Yorkshire North Wales (Flintshire and Moel 

 Siabod — Jackson). Ireland. It is probably quite

Body oval, dorsal scutum oblong, with two lateral 

 rows of clavate setae on either side and four fine 

 bristles in a trapesium on the disk ; one curved 

 clavate scapular setae on each side and three sub- 

 scapular; vertical setae contiguous. Dorsal scutum 

 yellow brown, very finely pitted. Genital shield 

 without hyaline border, large co-terminous with the 

 ventro-anal shield on a transverse line ; the rest of 

 the outline of the posterior scutum circular, widest 

 near the middle.
