Type, S. silvicola Simon. 



M. Simon has constituted the genus Stenygrocercus, with a 

 New Caledonian species as type, in which the lip is rather 

 square, both that and the maxillse free from spines. The superior 

 mammillse have the first and second joints of about equal length, 

 the last joint being not longer than middle, and the whole slim, the 

 first two joints about four times as long as wide. In many cases, 

 if not always, the second joint of the superior mammillae all through 

 this family is certainly retractile, and its comparative length there- 

 fore difficult to estabHsh unless fully extended. Apart from this, 

 however, the great diff'erence between the unbespined lip and maxillae 

 in this genus, and the profuse bespining of both in the two genera 

 Macrotliele and PorrJiotJiele, is a good generic characteristic. There 

 is no obvious thickening of the first pair of legs as in PorrJiothele. 



The front middle eyes are much smaller than the side, thus 

 greatly differing from those of Porrliotliele. 



Stentgeoceecits beoomi, n. sp. (Text-fig. 38, p. 271.) 



Cephalothorax, mandibles, sternum, and coxae deep chocolate- 

 brown ; eye-space and mandibular fangs black. Legs and palpi, 

 lip and maxillse rather lighter, edges of the latter paler and ruddier. 

 Eront median eyes greenish, remainder bright yellow. Hairs on 

 cephalothorax yellowish, on legs, palpi, and sternum dark brown. 

 Abdomen dark grey ground, with small paler yellow-brown pit- 

 marks over the upper surface. 



The cephalothorax is Ij mm. longer than broad, only slightly 

 narrowing in front and rear. A deep round fovea and four well.- 

 marked depressions on either side.
