Hermannia arrecta,* Nic, PI. XLIII, figs. 8 — 15 ; 



PI. E, fig. 1; PL F, fig. 15. 



Hermannia arrecta, Nic. P. 470. 



Average length about '72 mm. 



Average breadth about *49 mm. 



Average length of legs (first pair) about "36 mm. 



Average length of legs (second pair) about '30 mm. 



Average length of legs (third pair) about '32 mm. 



Average length of legs (fourth pair) about "40 mm. 



This species is readily distinguished from all other 

 British species which I am acquainted with by the 

 lateral projections of the abdomen. 



Colour dull red-brown ; the adult often carries a very 

 thin nymphal cast skin, and then it appears whitish. 



Texture dull and rough. 



Cephalo thorax considerably narrower than the abdo- 

 men ; covered with scattered dots thickly but irregu- 

 larly placed : it is divided more or less into two parts 

 by a transverse depression not very far from the tip 

 of the rostrum. There is just an indication of a rough 

 longitudinal ridge at the very edge of the cephalo- 

 thorax. Rostrum very blunt. Rostral hairs rather 

 long, curved, and far apart. Pseudo-stigmata large, 

 projecting, cup-shaped. Pseudo-stigmatic organs long, 

 slightly and gradually thickened at the distal end, the 

 absolute termination being pointed, or almost so ; 

 the peduncles of the organs have a strong turn or 

 shoulder a little before they enter the pseudo-stigmata. 

 Interlamellar hairs very long and setiform ; there is 

 also a pair of similar hairs, not quite so large, on the 

 dorso-vertex, representing the lamellar hairs ; these 

 two pairs of hairs do not show suSiciently plainly in the 

 plate. There are not any tectopedia. Apodemata 

 very strong and joined to the sternum. 



Legs of moderate length, fourth pair passing the 



* Arrectus, erect, lifted up, steep.
