578 IV AR TRÂGARDH 



The epistoma (fig. 90) is longer, and of the teeth at the 

 odge, of it, 3 to 4 terminal and subterminal ones are much 

 longer than the others, which are comparatively smaller than 

 in the typical form. 



Mandibles (fig. 91). Lower jaw with longer terminal tooth; 

 behind the posterior tooth the edge is perfectly straight. Upper 

 jaw with only one tooth behind pilus dentarius ; pilus 

 basalis submarginal. 



Ventral side (fig. 92). 



Sternal shield with the usual 3 pairs of sternal hairs ; one 

 pair at the anterior margin ; one laterally on a level behind the 

 middle of coxae II ; and one pair on a level between coxae II 

 and III. Metasternal shields either completely reduced, or 

 very small and fused with the endopodal shields, which 

 are narrow, and coalesced with the metapodal shields, 

 bearing one pair of hairs. 



Epigynial shield fused with ventral shield. The border 

 between the two is, however, demarcated by a pair of narrow 

 incisions at the sides, on a level behind coxae IV. Thèse inci- 

 sions are narrower than in the female delineated by Berlese, 

 and point obliquely forwards. The portion in front of them, 

 the epigynial shield, bears only one pair of hairs, submar- 

 ginaUy, on a level with the posterior side of coxae IV ; the rest, 

 the ventral shield, bears very numerous hairs. 



Inguin al shields of the typical shape, with net-like texture ; 

 no hairs. 



Stigmatanot placed so far back as in B's figure, but on a 

 level between coxae III and IV; peritrematic shields larger, 

 extending backwards on to a level with the posterior side of 

 coxae IV, so as to become contiguous to the inguinal shields. 

 Near the posterior margin there is another stigma or stigma 

 shaped dépression much smaller than the ordinary one. 



Legs. Legs II larger than the others.
