742 NOTES ON AUSTRALIAN COLEOPTERA, 



prothoracis angulis posticis vix rufescentibus ; capite prothorace 

 et elytris punctis majoribus seriatim (ut H. Te^yperi dispositis) 

 instructis, his capillos subtiles ferentibus ; mesosterni carina antice 

 baud abrupte declivi. [Long. 6-7, lat. 3-3J lines. 



Maris palporum maxillarium articulo 3° valde dilatato. 



Of the elytral stripes (which are of a dull pale green colour) the 

 first is close to the suture, the next 4 coincide with the rows of 

 larger punctures, the last is very near to the lateral margin. 

 Apart from colour this species differs from Tei^ijeri as follows, — it 

 is a broader insect with less parallel sides, the surface is a little 

 more conspicuously punctulate, the hind angles of the prothorax 

 are less rounded off, the penultimate joint of the maxillary palpi 

 in the male is very much more strongly dilated, and the meso- 

 sternal carina is much less abruptly declivous in front. This 

 latter character, inter alia, will distinguish the species from H. 

 Bovilli. 



I observe in the three species of this genus a character that had 

 escaped my attention when I described the generic characters ; — 

 the mesosternal keel is nicked by a little emargination close to its 

 anterior declivity, and this makes the extreme front appear as a 

 small conical tubercle. 



I have dedicated this insect to Mrs. Bovill, who has recently 

 given me three specimens of it from the N. Territory of S. 

 Australia, and whose explorations in that interesting region have 

 brought to light not a few new species.
