PSEUDOSCORPIONS FROM FORMOSA. I. 127 



stemlets, which often cohere in pairs; sometimes the two inner 

 stemlets, sometimes the three lateral ones are coherent. It looks 

 as if the galea could be unfolded or folded up like a fan, or 

 in other words that it might be somewhat movable in the arti- 

 culation at the base. 



Legs with pointed hairs; the femora of the two posterior 

 pairs of legs rather broad. The outer corner of the coxa of 

 the I. pair of legs with a small protuberance. The coxae of 

 the IV. pair broadly concuri'enl. Claws simple. 



There is no essential difference between the two sexes. 



Length 2 mm., width 0,72 mm. 



Measurements. Céphalothorax: long. 0,57; lat. 0,54. Man- 

 dibles: long. 0,26. Femur: long. 0,50; lat. 0,17. Tibia: long. 

 0,31; lat. 0,20. Hand: long. 0,40; lat. 0,27. Fingers: long. 

 0,36 mm. 



Habitat. Formosa: Koroton (Hans Sauter 1907). Hundreds 

 of specimens were exammed. 



The new species closely resembles Ideohisium quadrispi- 

 nosum Tullgren from Natal in South Africa, and I should have 

 been inclined to refer the Formosan specimens to this species, 

 if Mr. Tullgren who has kindly examined some of my speci- 

 mens and compared them with the African form, had not found 

 sufficient characters for distinguishing them. These characters are 

 the following: the African form has the céphalothorax broader 

 than long, the Formosan as long as wide; the African species 

 has the galea longer and divided into 4 parts, apparently from 

 the very base or at any rate nearly from the base; in the For- 

 mosan species the galea is smaller and of a different shape, as 

 will be seen from the description, but it may vary a good deal.
