SECTION III. (GROUPS IV. -VII.). 



The limits between this section and the preceding one are not 

 as clearly defined as I could wish, as there are a few species in 

 each section which I have placed there with more or less doubt. 

 However, since all the species whose head presents the appearance 

 of a "trilobed outline" belong to this section with the addition of 

 very few others, — it will be only in respect of a very small number 

 that doubt can arise ; — especially as in most or all of those placed 

 in this section and yet not showing indications of a " trilobed out- 

 line " of the head, — the labram rises vei'y markedly above the 

 clypeus. 



GROUP IV. 



Mr. T. G. Sloane has lately sent me two examples taken at 

 Mulwala, N.S.W., that appear to be identical with my H. sitb- 

 metallicus from Port Lincoln. 



GROUP V. 



H. DUBius, Blackb. 



I have recently received from Mr. McDougall (of Moonta) an 

 example which perhaps belongs to this species, though it is smaller 

 than the type (long. 4 lines) and of a much darker colour, — 

 except the antennae which are testaceous ; it differs from the type 

 also in being much more pubescent (the type is an old and pro- 

 bably abraded specimen) with the hind angles of the prothorax 

 appearing slightly more defined, the apical membrane of the elytra 

 a little more apparent and the external teeth of the front tibise a 

 little sharper. It was taken near Adelaide. 



H. NASUTUS, Blackb. 



In the original description of this species the hind claws were 

 called " appendiculate " without further remark, — but it would be 

 well to note that the claws have very much the appearance of 

 those which I have called " bifid," the inner apex of the basal
