546 IVAR TRAGARDH 



Hairs of the dorsal shields small and inconspicuous ; there 

 are II pairs of them on the anterior shield, placed as shown in 

 figure 38 ; only 3 pairs of hairs in the posterior half ; the ante- 

 rior one of thèse points obliquely forwards and outwards, and 

 is about 3 times as large as the others ; tins pair presumably 

 corresponds to the « pili scapulares » Berl., which are a pro- 

 minent f eature of both nymphae and adults of Parasitus, Perga- 

 masus, Eugamasus and others, but in G. armatus they are 

 placed considerably farther back. One pair of small vert ex 

 hairs, posterior shield with 11 pairs of small hairs. 



Gnathosoma. Epistoma large, triangular, with very 

 irregular edges (fig. 39). 



Mandibles (fig. 40) with narrow, pointed chela; lower jaw 

 shorter than the upper one (8:11), tapering gradually through- 

 out, with straight ventral edge ; terminal tooth small, with 

 one subterminal tooth of equal size ; besides thèse, in the dis- 

 tal half, 3 small, sharp teeth, directed backwards, the two 

 anterior ones of which are only half as far apart as the distance 

 between the médian and posterior one. 



Upper jaw sliaped difïerently to that of G. carabi G. et R. Can. 

 In the latter species it is easy to see from Canestrini's drawing 

 that the « calcar » is not fused with the jaw, but projects from 

 near the top of it ; the latter is of usual sliape, curved near the 

 top, and has about 8 small teeth. In G. armatus, on the other 

 hand, the calcar is so completely fused with the jaw that I 

 hâve been unable to trace any lines of démarcation between 

 them. The upper jaw (including the calcar) is narrow, lanceo- 

 late, and finely pointed at the top ; along the ventral margin, 

 interiorly, there is a tliin blade with convex edge. 



I hâve not been able to discern any pilus dentarius or 

 pilus basalis;to ail appearances they are reduced. The 

 so-called flagellum consists of a number of very short hairs. 



Palpi (fig. 41) with short joints, none of which is longer 

 than it is wide, and tapering successively towards the top ; 

 the two bristles of the médian side of joint III, which in
