triangular, and bordered by an infra-marginal 

 ridge as in Trachyuropoda. Dorsum smooth, con- 

 cave along the middle hne, with a ridge on either 

 side, smoothly rounded. Median strip outhned by 

 setae. Posterior setae close together, acute. They 

 overlooked a small detached scutellum, narrow- 

 transverse. Lateral margins beset with short 

 curved spines ; 3 or 4 nearest to the posterior margin 

 short, straight and farther apart than the rest. 

 Just within the posterior margin are the four 

 characteristic short foliate setae. 



Genital aperture of male circular, its fore margin 

 opposite the interval between coxae ii and coxae iii. 



Two males sent from Newton Moss, Penrith, by 

 J. C. Varty-Smith. 



43. Dinychus bisetis, sp. nov. 67. 



Very lil-ie inertnis and similarly pitted, closely and 

 deeply : but — the pseudo-capitulum is much larger 

 with two frontal setae and the marginal scutum is 

 not continued upon it ; the two posterior setae 

 correspond to the lateral two of tefraphylhis ; they 

 overlook a broad indentation in the marginal 

 scutum, but it does not include a definite scutellum 

 as in the preceding species. 



In manure heaps, not uncommon. West Allendale. 



44 Dinychus tetraphyllus, Berl. 66, G7. 



Fairly plentiful; usually on dead wood, or under 

 bark. 



Ireland, in moss. 



45. Dinychus fossor, sp. nov. 67. 



Much like teiraphyllus in general appearance, but 

 the four large setae are placed as in Cillibano 

 virgata. 



Moles' nests, West Allendale.
