and regular (PL Gr, fig. 11, which, however, is not on 

 a sufficiently large scale to show the corrugations). 



The adults of this genus are found chiefly in moss 

 and lichen, many species being almost confined to the 

 latter, but some species are to be found in various 

 materials. 



The larvEe and nymphs of many species have a con- 

 siderable resemblance to the adults and might prob- 

 ably be supposed to be the immature stages(^. serrata) ; 

 others are not unlike, although wanting in the minute 

 details which distinguish the species of the adults. 

 Finally there are larvae and nymphs which are very 

 difi'erent from the imagos {N. bi]jiliSi N. laciistris, 

 N. ohlonga). 



The genus is probably most nearly allied to Damaus ; 

 in some species as N. monilipes^ N. sjjlendens, the 

 clavate or moniliform shape of the joints of the legs, 

 so characteristic of the last-named genus, is very 

 marked. In some species the projecting antero-lateral 

 corners of the abdomen seem like the rudiments of 

 pteromorphse ; thus the resemblance of N. tibialis to 

 Oribata Lucasii is striking. 



N. bipilis and N. monilipes must be considered as 

 extreme species at the difi'erent ends of a series. A 

 great number of the minute monodactyle species appear 

 at first hopelessly alike, but a little practice will 

 enable the student to distinguish them without diffi- 

 culty, when he can see them clearly under a sufficient 

 amplification, say 150 to 200 diameters.
