Some outline details of these species are given for 

 purposes of comparison. 



Group 1. 



LlPAEETRUS NIGER, n. Sp. 



PI. xxxvii., fig. 116. 



(3 . Black ; front tibiae, antennae (club excepted) and 

 palpi more or less reddish. Front of head, pronotum 

 (including disc) and elytra about base and near suture, with 

 erect, straggling hair, varying from dingy-whitish to dark- 

 brown; under-surface, hind parts ( 16 ) and legs with denser 

 and mostly whitish hair. 



Head with crowded and more pr less confluent punctures, 

 becoming sparser and larger on clypeus; sides and apex of 

 the latter rather strongly elevated, apex truncate, its sides 

 acute and produced. Antennae nine-jointed. Prothorax 

 with sides strongly rounded, hind angles rounded off, the 

 front ones acute; with numerous fairly large punctures, 

 mixed with smaller ones on disc, becoming crowded and more 

 uniform in size on sides. Elytra with rather large punctures, 

 becoming smaller towards side and apex, geminate-striae 

 irregular. Hind parts with punctures much as on disc of 

 pronotum. Front tibiae very obtusely tridentate; basal joint 

 of front tarsi narrow at base, inner edge then suddenly 

 dilated and keeled, front claws considerably thickened at 

 base, basal joint of hind tarsi distinctly shorter than second. 

 Length, 10 mm. 



Hob. — Western Australia: Kalgoorlie. Type (unique), 

 I. 7834. 



As the elytra are clothed beyond the base (although the 

 clothing there is not very dense) the species belongs to Group 

 1, and there it would be associated with ater, from the 

 description of which it differs in having the punctures of the 

 head not "minute," prothorax shining, with numerous fairly 

 large punctures and the geminate-striae of the elytra feeble; 

 Blackburn, in commenting upon ater, considered it possibly a 

 variety of phoenicopterus ; the type of thi6 differs from the 

 male of phoenicopterus in having the clypeus truncate in 

 front, and less produced at the sides, larger punctures, sparser 

 clothing, black elytra, and very obtuse teeth to front tibiae. 



(16) The propygidium and pygidium are the parts referred to 

 as hind parts.
