I have compared the type specimens of C. kevigatum and C. 

 frontale in the Macleay Museum, and consider them to be the 

 same species. 



Carenum murrumbidgense, Macl. 



C. punctulatum, Macl., Trans. Ent. Soc. N.S.W. 1865, i. p. 143; 

 C. murrumhidgensf, Macl., I.e. p. 183. 



After comparing the type specimens of C. punctulatitin and C. 

 murrumhidgeyise in the Macleay Museum I have no doubt they 

 are synonymous. The rows of fine punctures on the elytra from 

 which C. puncfiilatum derives its name are certainly a post mortem 

 effect caused by submersion in alcohol ; therefore, though this 

 name has a priority of about twelve months over C. murrtim- 

 hidyense, 1 think it should be discarded. It is probable that C . 

 iinirrumbidgense is not actually a species distinct from C. Icevi- 

 yntum, but I hesitate to unite them on the evidence in my posses- 

 sion, though I do not know any characters that difl:erentiate 



them. 



Carenum puncticolle, Macl. 



This species is very close to C. hevigatum. 



Carenum kingi, Macl.; and C. propinquum, Macl. 



It is doubtful if there is any actual difference between these 

 species, which are very closely allied to C. m,urrumbidgense. I 

 have not examined the types carefullj', but have noted that the 

 single type specimen of each in the Macleay Collection is without 

 supraorbital punctures on the sides of the head. 



Carenum convexum, Chaudoir. 



I have not satisfactorily identified this species; it is evidently 

 very closely allied to C. ia7ithinum, Macl., and indeed seems to 

 me not unlikely to be that species. 



Carenum ianthinum, Macl. 



I regard a species sent to me by the late Mr. G. Barnard from 

 Duaringa, Queensland, as this species. It is allied to C. Icevi-
