Description: Length — 1 mm. Color — White. Antennae — 

 Short, slightly longer than head ; I shortest, II pear shaped and 

 longer than III, IV as long as II and III. Ocelli — Wanting. 

 Claws — Two ; superior armed, two teeth on inner margin, the 

 basal one being the longest; inferior runs out in two diverging 

 ])oints ; one simple tenent hair on the tibia. Furcula — Dentes 

 longer than manubrium and twice the length of the mucrones; 

 mucrones with two teeth and a short basal spine. 



Variation: Those I have found here do not vary among 

 themselves but ditfer in some instances from those described by 

 other authors. Lie-Pettersen gives the size of those he de- 

 scribed as 1.5 mm. and those of Guthrie correspond to this. I 

 didn't find any that were quite that large. Lie-Pettersen seems 

 to have overlooked the smaller tooth on the superior claw and 

 Collinge the same, for it does not appear in either of the 

 descriptions. 



Hahitat: Claremont, under a rock. This was the only place 

 that I found them. Nicolet says that they "inhabit worm- 

 eaten trunks" and Collinge found his in ants' nests, while 

 Guthrie found them very common among damp decaying leaves
