i8. Urodinychus janetii, Berl. 66,67. 



With Formica rjifa and F. fusca. Rather dingy 



looking. 

 Lancashire, Yorkshire (J.W.H.H.) 



19. Urodinychus campomolendimis, Berl. 



Ireland ("commonly under bark" — Halbert). 



20. Urodinychns pttnctatissimus, Halb. 



Ireland (Achill Island, one $ in moss, Halbert). 



21. Urodinychus roseus, sp. nov. 67. 



Length 500/x. Form of body and dorsal scuta as in 

 janetii, but cuticle quite smooth and rathe*r glossy, 

 and the punctures are finer and farther apart. 

 Median scutum with three series of fine longish 

 hairs on each side. Genital valve of $ a broad 

 ellipse truncate behind, very broadly rounded in 

 front : this and the whole ventral scutum punctured 

 like the dorsum. 



Ninebanks, 2 females : note of habitat lost, but 

 almost certainl}' from manure. 



22. Urodinychus ovalis. Koch. 67. 



Claret brown. 



West Allendale, usually in manure, but once or twice 

 on damp boards laid out as traps. 



23. Urodinychus thorianus, Berl. 66, 67. 



Like the preceding in form, size, and colour, and 

 described by Berlese as a variety of it. The habitat 

 is quite different so far as my observations go. 



Under bark of standing trees, Ninebanks, Birtley; 

 also in moss occasionally. 



Ireland, under bark. 



24. Urodinychus minusculus, Hull. 



Grange-over-Sands, in a mole's nest (R. S. B). Not 

 very happy in this company, but cannot be 

 included in Tracliyuropoda (which it resembles 

 very closely).
