and minute scratches on the elytra as in that species. C. subcos- 

 totuni shows a faint trace of the longitudinal ridge of the sub- 

 orbital channels, but has only two marginal punctures on each 

 side of the prothorax. The four apical punctures of the elytra in 

 C. opacicol/e are a remarkable character for a Carenum.

Since publishing my previous note on the synonymy of Carenum 

 interruptum, Macl.,* I have examined the type specimen of C_ 

 obscurum in the Macleay Museum, and found it conspecific with 

 C interruptitm. 



Carenum scaritiodes.

 Macl., I.e. p. 178.t 



A comparison of specimens in my possession with the types of 

 Macleay's species given above has convinced me that these are 

 only synonyms of C. scaritiodes, Westw.; I also regard C. inter- 

 mediuni, Westw., as founded on the same species. The punctura- 

 tion of the elytra in C. striato-punclulataiii is certainly a post 

 mortevi effect.

 so uamed in the Macleay Museum; it is identical with C -scar it hides.
