15. Notaspis clavipectinata var. calva, n. var. 



In size and details of structure apparently precisely like N. clavipectinata except 

 that the clavate pseudostigmatic organs are destitute of the hairs present on those of 

 the type. 



Moss, Silhouette. 



16. Notaspis impolita, n. sp. (PL 18, fig. 12). 

 Length about "4 mm. 



Dark, piriform, texture rough. Cephalothorax long, rather bluntly pointed. Lamellae 

 ridge-like extending from pseudostigmata to near the anterior border. Pseudostigmatic 

 organs of medium length, curved, the thickened terminal portion roughened. Abdomen 

 with four rather conspicuous hairs on dorsum and six very short clavate hairs at posterior 

 end. Legs with nearly circular femora in lateral aspect. Tridactyle, heterodactyle. 



Moss, Silhouette. 



17. Notaspis reticulata, n. sp. (PI. 18, fig. 13). 

 Length about '5 mm. 



Colour dark, the whole surface reticulate, the cells of the reticulation largest in the 

 median region of the abdomen. Cephalothorax rather broad and blunt anteriorly. 

 Lamellae narrow blades on edge. Pseudostigmatic organs fairly long, thick, clavate, 

 roughened and darker coloured at the end. Palps well visible dorsally. Abdomen flat 

 dorsally, fringed posteriorly with detachable material held by strongly-curved clavate 

 hairs. Legs short, stout, with similar fringing material held by clavate hairs, but easily 

 removed. Tridactyle. 



Moss, Silhouette. 



18. Notaspis lamellicornis, n. sp. (PI. 18, fig. 14). 

 Length about "52 mm. 



Cephalothorax long and pointed. In size and general appearance the mite closely 

 resembles N. maculosa (Warburton and Pearce, Proc. Zool. Soc, 1905, ii. p. 5()7) but the 

 lamellae are short and converging, and the general texture is less roughened. The abdomen 

 possesses numerous hairs. Legs monodactyle. The pseudostigmatic organs are long and 

 pectinate, recalling the antennae of a lamellicorn beetle. 



Moss, Silhouette. 



19. Notaspis Jlagellata, n. sp. (PI. 17, fig. 9). 

 Length about "55 mm. 



Cephalothorax long and pointed, without lamellae; the hinder portion extremely 

 gibbous. Pseudostigmatic organs characteristic, being at first straight and clavate, but 

 produced beyond the oval club-head into a whip-like process of somewhat greater length. 

 Abdomen sub-circular, bearing a few very short hairs. Legs long and slender; monodactyle. 



This mite bears a general resemblance to the very Notaspis-Yike Damceus nitens, but 

 it undoubtedly belongs to the genus Notaspis. 



Moss, Palm Valley, Praslin.
