the tarsi have the fifth joint glabrous beneath. My specimen has 

 been many years in my possession, with the locality " Rockhamp- 

 ton District" attached to it; but I do not know the authority 

 for this. It is in all probability S. rockhamptonensis, for I do not 

 think S. vhesulus extends to Queensland, and therefore can not 

 follow Chaudoir in placing it under S. ohesulus. It is very closely 

 allied to S. monarensis. 



Sarticus sulcatus, Macleay. 



Coronocanthus sulcatus, Macl., Proc. Linn. Soc. N.S.W. 1878, 

 ii. p. 216: Feronia (Sarticus) quadrisulcatus, Chaud., Bull. Mosc. 

 1878, liii. p. 67. 



I am not prepared to accept Macleay's genus Coronoca7ithus 

 as distinct from Sarticus, and therefore support Chaudoir's refer- 

 ence of the species to Sarticus. 



Attention may be drawn to — the abnormal sculpture of the 

 elytra; the border along the apex of pronotum obsolete in middle; 

 prosternum not bordered along anterior margin; ventral segments 

 not punctate; basal segment impunctate, and with a wide raised 

 border behind metasternal epimera and posterior coxoa. 



The basal ventral segment requires studj'' in Notonomus, Sarticus 

 and allied genera. It varies by being punctate or impunctate; 

 the lateral border of the ventral segments sometimes curving 

 across the segment behind the metasternal epimera, sometimes 

 not, rarely it is the second segment which has the anterior margin 

 bordered; these variations seem constant, and are therefore useful 

 as a help in differentiating species. 



Sarticus blackburni, Sloane. 



Pte7^ostichus blackburni, SI., Proc. Linn. Soc. N.S.W. 1894 (2), 

 ix, p. 426. 



This species may, at least provisionally, be referred to Sarticus. 

 It has the prothorax with basal angles marked, anterior margin 

 not bordered in middle; prosternum with apex not bordered; 

 ventral segments lajvigate, the basal segment impunctate and 

 without a raised border behind metasternal epimeron.
