124 EDV. ELLINGSEN. 



long as broad, the inner side slightly convex, abruptly and 

 strongly widened posteriorly from the stalk, in most of the cen- 

 tral part somewhat concave, at the extremity a little convex; 

 femur tapering slightly throughout towards the tip. Tibia with 

 a short stalk, a little shorter and a little broader than femur, 

 the outer side regularly convex, the inner side somewhat swollen 

 in the central part, a little concave towards the extremity; tibia 

 on the whole rather tapering towards the tip. Hand with a 

 short stalk and with an obliquely rounded base, almost trian- 

 gular (the fingers included), on both sides slightly convex, passing 

 quite gradually into the fingers. Fingers robust, gradually ta- 

 pering distally, somewhat curved, as long as the hand, with 

 several long, fine, tactile hairs. — The palps of this species 

 highly resemble the figure which Tullgren gives of Ch. suh- 

 tropicum, with the exception of the hairs, which in this species 

 are simple and pointed. 



Mandibles. Galea simple, without teeth. 



Legs. The legs, including the coxae, are very similar to 

 those of Ch. suhtropicum, the posterior pairs are, however, 

 somewhat more slender; the coxae of the IV. pair are concave 

 posteriorly, and lacking the apical protuberance indicated by 

 Tullgren for his species. Claws simple. 



Length 1,09 mm.; width 0,72 mm. 



Measurements. Céphalothorax: long. 0,33; lat. posteriorly 

 0,43; front margin lat. 0,10. Femur: long. 0,29; lat. 0,09. 

 Tibia: long. 0,20; lat. 0,11. Hand: long. 0,18; lat. 0,15. Fingers: 

 long. 0,18 mn). 



Habitat. Formosa: Takao (leg. Hans Sauter, 28. VIII. 

 1907). 1 cf. 



The new species, as indicated above, is nearly related to 

 Cheiridium suhtropicum Tullgren, from Zululand, and has 

 especially, in common with that species, the above-mentioned 

 teeth of the posterior margins of the céphalothorax and the an- 

 terior five tergites; by which character these two species differ
