 In my tabulation of the species of Mcechidius (loc. ctt.) 

 this species must be placed beside M. caviceps, Blackb., from 

 which it differs by, inter alia, its clypeus considerably less 

 deeply excised with the lobes of the excision rounded (not 

 externally angulate) in front, and by its elytral sculpture 

 [which in cavicepF;, Blackb. consists of about 18 striae, — the la- 

 teral ones scarcely defined, — the interstices scarcely and inter 

 se subequally convex and obscurely seriate-granulate ; while in 

 relictufi the elytra cannot be called distinctly striate the sculp- 

 ture consisting of rows of punctures (some of them moderately, 

 others very, large) among which are about 5 irregular dis- 

 tinctly elevated intervals having their sides strongly crenulate 

 by the adjacent punctures]. In my original description of 

 M . caviceps I did not mention the granulation of the elytral 

 interstices. The granules are small and inconspicuous (less so 

 on the sides and apical parts of the insect) and were concealed 

 by a thin indumentum which I find was present on the typi- 

 cal specimen in the S.A. Museum: but inspection of the ely- 

 tral interstices of a second example recently acquired by me 

 shows the presence of fine granules.

In my tabulation of the species of Ma^chidins (Joe. eif.J 

 this species must be placed beside 31. rugosipes, Blackb., from 

 which it differs by infer alia its clypeus truncate in front and 

 its prothorax scarcely transverse. Its short robust posterior 

 tibiae with their external face transversely carinate at about 

 the middle of their length so that the outline appears strongly
