NEW SOUTH AFIUL'AN ARACHNIDA. 295' 



CryphoeceEe mainly on account of the dentition of the 

 clielicei-Ee; probably the separation of the two groups is 

 artificial. Whether this genus can be regarded as a direct 

 derivative of the South i\^frican terrestrial fauna, or whether, 

 like Desis, its allies are widespread over the shores of the 

 southern hemisphere, cannot be stated at present ; it does 

 not seem to be closely related to the various known littoral 

 species recorded by Mr. H. R. Hogg.^ 



Fam. ARGIOPID.^.

Genus Erigonopsis gen. nov. 



This generic name is proposed for the reception of the 

 species hereafter described, which combines the characters of 

 various members included in Simon's world-wide group 

 Erigonea3, but does not agree entirely with any one of them, 

 and in some respects approaches the group Liny phi a\ The 

 characters of the male palp will probably prove sufficient to 

 differentiate this from any other known genus. Other 

 characters are : carapace of male siinple, precisely like that of 

 the female ; no trace of fovea or median sulcus on carapace ; 

 length of quadrilateral formed by the four median eyes 

 slightly greater than its hind width ; posterior median eyes 

 very slightly nearer to each other than to the posterior 

 laterals ; sternum with a rather broad posterior prolongation, 

 separating the bases of the foui'th legs from each other, 

 followed, posteriorly to the coxas, by a small flat quadrangular 

 piece ; abdomen without scute or indurated area ; female 

 epigyne comparatively simple ; female palp without tarsal 

 claws, the maxillge not very broad even in the male (more or less 

 intermediate between Erigone and Liny phi a) ; chelicerje 

 with four teeth on the anterior margin of the fang-groove and 

 thi'ee on the posterior margin in both sexes ; tarsus of first leg
