This and the following two species display a character 

 which distinguishes them sharply from all the rest of the 

 known Australian Heteronyces, in the clypeus being raised 

 in front into an erect narrow lamina, the height of which is 

 equal to about half the distance from its base to the clypeal 

 suture. The claws of all three are appendiculate, but more 

 or less (least in this species) of the subbifid type discussed 

 under the heading of Group IV. (Trans. Roy. Soc, S.A., 

 1909, p. 39). They belong to the 2nd subgroup of Group IV., 

 and their place in the tabulation of that subgroup is indi- 

 cated under the heading of H. pedarius, Blackb. The punc- 

 tures of the dorsal surface in this species are not numerous, but 

 owing to their large size they are tolerably close to one another.
