9 • Differs in being smaller (7-8 mm.). Head smaller, 

 with denser and coarser punctures; mandibles short, stout, 

 narrowly keeled at outer edge, and cuspidate at middle of 

 inner edge, with coarse punctures and much sparser hairs. 

 Prothorax with coarser and denser punctures, margins nar- 

 rower but more strongly crenulated, and discal foveae feeble. 

 Elytra slightly wider, with stronger and denser punctures and 

 wrinkles ; and legs shorter and stouter. 



Hab. — New South Wales: Dorrigo (H. J. Carter, from 

 R. J. Tillyard and W. Heron). Type, I. 2729. 



The mandibles of the male vary greatly in size, on some 

 specimens they are longer than the head is wide, on others 

 they are scarcely longer than those of the female. Each may 

 be compared to a piece of thin metal that has been irregularly 

 shaped ; starting from the front of the head the base is some- 

 what rounded, then there is a wide curve extending to the 

 apex, with the outer wall almost vertical; from the apex it 

 is curved backwards for about one-fourth its length, where 

 there is a distinct tooth, behind this there is usually a feeble 

 one, and thence to the base it is feebly undulated. When 

 the pair are clenched the right one overlaps the left ; the 

 basal third of each almost touch, the apical two-thirds form 

 an elongate-elliptic opening. The elytra in the large males 

 are slightly narrower than the prothorax at its widest, but in 

 the small males they are quite as wide. The hind tibiae are 

 sometimes scarcely darker than the femora. The front of 

 the head is usually diluted with red.

Anoplogxathus concinnus, Blackb. 

 The type, and a co-type of this species, are simply small 

 specimens of ceneus from which the metallic-golden lustre has 

 been almost entirely removed; almost certainly through 

 immersion in formalin. I have seen specimens of master si in 

 exactly the same condition. Also specimens of Anoplostetkus 

 l<ztus from which it has been removed in spots. A few years 

 ago Mr. Hacker had many of his Northern Queensland speci- 

 mens injured in exactly the same manner through placing 

 them in formalin.
