120 REVISIONAL NOTES ON AUSTRALIAN CARABID.r., II., 



species. C. anthracinum, Macl., C. inter r upturn, Macl., and C. 

 Icf.vigatum, Macl., are species which var}'^ in colour, some speci- 

 mens being wholly black, while others have the sides brightly 

 flushed with purple. 



Carenum subporcatulum, Macleay. 



Trans. Ent. Soc. N. S. Wales, 1865, i. p. 184; C. mridimar- 

 ginatum, Macl., I.e. 1871, ii. p. 97: C. politulum, Macl., I.e. p.98. 



I have already published the identity of C. politulum, Macl., 

 with C. subporcatulum, Macl. (these Proceedings, xxv., 1890, Pt.3, 

 p.379); I have since carefully examined the types of C. viridi- 

 marginatum, Macl., in the Australian Museum, and have no 

 hesitation in placing that species as a synonym of C. subjyorca- 

 tulum. 



Hah. — S. Q. : Gayndah (Masters), Ipswich {jide, Macleay), 

 Finche's Creek (-40 miles S.W. from Dalby; Sloane). 



Carenum kixgi, Macleay. 



Trans. Ent. Soc. N. S. Wales, 1869, ii. p. 64; C. propinquum, 

 Macl., Ic. 



Formerly I expressed doubt as to the specific difference of C. 

 kingi and C. propinqiuun (these Proceedings, 1897, xxii., p. 205). 

 I have since compared the types of these species in the Macleay 

 Museum and could find no reason for keeping them separate. 



Carenum cyanipenne, Macleay. 



Trans. Ent. Soc. N. S. Wales, 1869, ii. p. 62; C. nitescens, 

 Macl., I.e. p. 6 4. 



I have hitherto been unable to indicate the position of C. 

 nitescens, Macl., in the genus Carenum,* but having recently 

 carefully examined the type-specimen of C. nitescens in com- 

 parison with the type of C. cyanipenne (both in the Macleay 

 Museum), I am compelled to consider these one species, C. 

 7iitescens being a specimen in which the two posthumeral dis- 

 coidal punctures of the elytra are wanting, as sometimes happens 

 in other Carenums with 4-punctate elytra.
