570 NOTES ON AUSTRALIAN COLEOPTERA, 



can be traced to a little distance behind the middle. The lateral 

 gutter of the prothorax is wide and fairly defined and that of the 

 elytra is as in H. rotundata except in not being at all narrowed 

 behind, but rather the reverse owing to a little flattening out of 

 the apical part of the elytra. The elytra are very peculiar being 

 strongly convex towards the front both laterally and longitudinally 

 so that their greatest height (viewed from the side) is very near 

 the front ; they have a triangular depression behind the scutellum 

 as in Nyctozoilus and their surface is evidently (though widely 

 and feebly) prominent in three longitudinal lines on each side of 

 the suture which itself forms an additional and similar prominence ; 

 their sides are moderately rounded and are at their widest slightly 

 in front of the middle. The suture between the metasternum and 

 its episterna is nearly straight. In the example before me only 

 two joints of a front tarsus are extant ; these are both shorte'' 

 than is customary in specimens with tomentose hinder tibiae ; the 

 basal joint is channelled beneath like the 2nd than which it appears 

 above quite twice and below quite three times longer.
