127. Cyrtolaelaps herculaneus, Berl. 66, 67. 



The largest species, which with kochii and transisalae 

 ascends to the sphagnum of the fells in West 

 Allendale. Probably of wide distribution, but 

 there are no records. 



128. Cyrtolaelaps nemorensis, K. 66, 67, 68. 



A small species common among grass and in moss 

 of woods. 



Cheshire, Yorkshire, Lancashire, Cumberland, Flint- 

 shire, Ireland. 



129. Cyrtolaelaps humilis, sp. nov. 67. 



Similar in form and size to nemorensis of which it 

 may possibly prove to be a variety though I have 

 no reason for believinir that it is.
