South African Pselaphidce. B83 



arcuate in the middle, one-half wider than the apex ; disk evenly 

 convex anteriorly; basal impression large and deep. Elytra at 

 base slightly wider than the prothorax ; sides more strongly 

 arcuate near the apex ; disk depressed, distinctly longer than the 

 head and prothorax together. Abdomen slightly shorter than the 

 elytra, equal to the latter in width. Length, 1*5 mm. 



Wellington, South Africa. 



The structure of the vertex is somewhat peculiar, the 

 median tubercle being connected with the anterior 

 margin of the clypeus by a corneous band, which 

 appears at first sight to be a strongly elevated carina, 

 but which is in reality entirely detached from the vertex, 

 except at its point of origin on the tubercle and clypeus. 

 The type is a female, the apex of the abdomen beneath 

 being unmodified ; it is the only representative which I 

 have seen.
