Colour lightish chestnut-brown. 



Texture highl}^ polished, entirely without markings. 



Shape inversely oval, i. e. the larger end forward ; the anterior 

 margin projects very slightly above the rostrum, but this projection 

 is rounded. The hinder part of the body is much more attenuated 

 than the front part. , The female is considerably wider in pro- 

 portion than the male, but still diminishes to a rounded point 

 behind. Dorsal surface considerably arched, particularly the an- 

 terior and central portions. 



Mandibles of male (fig. 4 a) have the fixed arm of the chela 

 greatly curved near the end, which forms a strong tooth ; there is 

 another large tooth close behind, and a much smaller one further 

 back ; the movable arm also ends in a strong curved tooth, just 

 opposite that of the fixed arm, and has one other strongish tooth. 

 Attached to the side of this arm is a large appendage, which is as 

 thick as the arm and projects beyond it ; it is of about equal breadth 

 until near the distal end, then it suddenly diminishes and has a very 

 small bifid termination. Epistorae (fig. 4 b) almost five-sided, the 

 median side very short, with a small point at each end directed for- 

 ward ; the whole anterior portion of the epistome is edged with very 

 fine points or teeth. There are a few extremely fine and small 

 white hairs on the dorsal surface, too small to be depicted in a 

 drawing on the scale of the figure ; one pair, however, near the 

 posterior end are considerably larger, although still small. 



The under surface of the female has the plates arranged in a 

 manner similar to that figured in Lcelaps cuneifer. 



Legs in both sexes without apophyses ; all legs terminated by 

 claws and caruncles. 



Hab. Found commonly in the nests of Aphanogaster testaeeo- 

 pitosa, Luc, near Ajaccio, in Corsica.
