convex, and near the apex of the lower edge is an impressed 

 bare area, above which are two very stout bifid spines and 

 some simple spines above them ; the other tibise have each 

 in the same position a row of three or four simple spines.

? . The scaling of the upper surface light grey-brown or 

 brownish grey, the markings that are so conspicuous in the 

 <^ being only faintly indicated owing to their being very 

 little lighter than the ground-colour. 



The only structural differences are that the prothorax is 

 proportionally broader, the apices of the elytra are jointly 

 produced downwards into a beak-like point, and the last 

 ventral segment is pointed at the apex and strongly com- 

 pressed at the sides so as to form a prominent median ridge. 

 In the $ this ventral segment is only slightly convex, 

 broadly rounded at the apex, and bears a small shallow 

 apical impression.

The male specimens were found on Acacia caffra and the 

 females on grass. 



This insect would have been referred by Faust to the 

 genus Embrithes, Schh., and is congeneric with his E. pla- 

 giatus and E. miser from East Africa. These insects are 

 unquestionably referable to Sphrigodes, Gerst., and it is 

 therefore probable that all the other tropical species of 

 Embrit/ies described by Faust should be assigned to that 

 genus. 



In the true Embrithes, which "are confined to the Cape 

 subregion, the scape does not extend beyond the front 

 margin of the prothorax ; the rostrum is short and broad, 

 being no longer than its basal width ; the surface of the 

 prothorax is uneven, and the upper edge of its basal margin 

 is not carinate. 



In Spltrigodes the scape extends well beyond the front 

 margin of the prothorax; the rostrum is much longer than 

 its basal width ; the surface of the prothorax is smooth, and 

 the upper edge of its basal margin is finely carinate.
