HYPOCTHONIUS BREVIS. 539 



Nymph. 



Is practically similar to tlie adult, but is much paler 

 in colour. 



Distribution. — I have found this species at the roots 

 of ground mosses in Bpping Forest ; I have not found 

 it often. It has been recorded in Germany. 



Hypocthonius BREVIS,* sp. nov. Plate XLIX, fig. 14. 



Average length about "18 mm. 

 Average breadth about "11 mm.

 Average length of legs (second and third pairs) about 

 •07 mm. 



Average length of legs (fourth pair) about '09 mm. 



An extremely minute, but thick- set species ; the 

 body is less mobile than those of other members of 

 the genus. 



Colour almost yellow, but shading off from yellow- 

 brown to nearly gamboge-yellow, the variation being 

 chiefly dependent on light and shadow. 



Texture dull and rather rough, but not distinctly 

 pitted as H. lanatus is. 



Shape approaching a short oblong, much less pointed 

 anteriorly and posteriorly than other British species of 

 the genus, except H. lanatus. 



Gephalothorax larger in proportion to the total size 

 than is usual in Hypocthonius. Rostrum rounded ; 

 rostral hairs large and slightly serrated. Palpi long, 

 they show distinctly for almost their whole length 

 from the dorsal aspect. Pseudo-stigmata dorsal. 

 Pseudo-stigmatic organs shortish, white, directed 

 nearly horizontally backward and slightly outward, 



* Brevis, short.
