I have only a single specimen of this species. I 

 unfortunately did not observe it during life ; I am 

 therefore forced, for the purpose of the plate and this 

 description, to rely upon the mounted specimen and 

 upon Berlese's figure and description. 



This species probably approaches more nearly to the 

 genus Herinannia, and especially to H. bistriata, than 

 any other Nothrus does : see the remarks on that sub- 

 ject in the description of the genus Hermannia (p. 439) 

 and in the description of H. histriata (p. 462). 



Colour dark-yellow, or reddish-yellow-brown ; Ber- 

 lese calls it " terreo-castaneits " (earthy chestnut). 



Texture. — Cephalothorax irregularly pitted, pits 

 about as wide as the intervening ridges. Abdomen 

 smooth but not polished. 



Cephalothorax. — Rostrum conical, tip truncated and 

 slightly rounded. Rostral hairs stout, curved, rough. 

 Behind the lamellar hairs the cephalothorax suddenly 

 widens in consequence of the presence of a large, 

 chitinous, mammilliform projection on each side; behind 

 this projection the first pair of legs are set, so that the 

 body appears deeply excavated for their reception ; 

 the homologue of the second tectopedium forms a 

 large, slightly bifid, lateral projection on each side 

 between the first and second leg. Placed between 

 these last-named projections are a second pair of
