TRÄGÅRDH, SPLLEORCHESTES, A SALTATORIAL TROMBIDIIDE 11 



Three pairs of flumose hairs, tlie median orie of which 

 is the shortest, as in the other species; they are placed as 

 in the other species. 



The eyes are small but very prominent; behind the eyes 

 the cephalothorax widens to two low cushion-shaped projec- 

 tions which are much more distinctly set of than in the 

 other species. These structures resemble very much those 

 I have found in Alichus rostraius Tgdh and seem to be some 

 kind of sense organs. 



The mouthparts. 



I have not been able to find any projecting between 

 the mandibles, as was the case with the other species. This

may however depend on that its is shorter and bent down- 

 wards, so as to become difficult to see. 



The mandibles (Fig. 10) are comparatively longer than 

 in S. formicarum, with straighter lateral side. Along the 

 median side, at the base, there is detached a low pear-sha- 

 ped portion detached, as in the other species. The shape 

 of the chela is extremely difficult to make out. In textfig. 

 10. both mandibles are delinested, in ^/i side view. We no- 

 tice at the base of the upper jaw a short unipectinated 

 hair. The upper jaw itself seems to be shaped as an oval, 

 very thin blade, the ventral edge of which is not visible on 

 account of the chela being closed.
