ON SOME PSEUDOSCORPIONS FROM JAPAN. U 



Colour. Sclerites pale greyish brown, céphalothorax, man- 

 dibles and palps pale reddish yellow, legs and interstitial parts 

 whitish. 



Céphalothorax longer than it is wide, nearly parallel-sided 

 up to the eyes, the latei'ai margins, however, being slightly 

 convex, a little narrower in front of the eyes, the front margin 

 from the middle slightly oblique, with a large tooth in the mid- 

 dle. The surface smooth and glossy with scattered, long, pointed 

 hairs. 



Abdomen. Tergites and sternites glossy, slightly striped, 

 with rows of long, pointed hairs along, the hinder margins. 



Palps about as long as the body, slender. Coxa smooth 

 and glossy. The other joints of the palps are more or less gra-

 the fingers, the femur being most granulated. The palps are 

 densely clothed with long, pointed hairs, somewhat longer on 

 the inner than on the outer side. — Trochanter stalked, consi-

 Femur slender, with a distinct stalk, the inner side neaily straight, 

 though slightly sinuated towards the extremity, the outer side 

 passing gradually from the stalk and nearly straight, the whole 

 slightly increasing in width towards the extremity. Tibia with 

 a rather long stalk, the inner side regularly convex, the proximal 

 part of the outer side nearly straight, somewhat convex towards 

 the extremity, in all scarcely narrowing at the extremity. Hand 

 with a short stalk, with the base obliquely rounded, the outer 

 side nearly straight, the inner side very convex, gradually pas- 

 sing into the fingers. Fingers slender, slightly curved, consi- 

 derably longer than tlie hand, with a dense row of low, obliquely 

 truncated teeth, on the inner margins. 



Mandibles. The fingers slender, long, crossing each other

 the outer side of the moveable finger; the moveable finger of
