the club is considerably darker than the rest of the antennae, 

 but is far from being black; the upper-surface has a vague 

 iridescence. The elytra of the type appear to have remnants 

 of a very short membrane. 



Group 17. 



LlPARETRUS FLAVICORNIS, n. sp. 



Black ; eltyra (base, suture, and margins excepted) and 

 legs more or less castaneous, antennae and palpi flavous. 

 Under-surface with dense pale hair, pronotum rather densely 

 and almost uniformly clothed with brownish hair, becoming 

 shorter, denser, and paler on head between eyes (clypeus 

 glabrous), elytra with rather long sparse clothing at base and 

 sides, becoming sparser and shorter towards middle, and 

 absent posteriorly; hind parts with moderately dense, and 

 mostly depressed, pale clothing. 



Head with small dense subasperate punctures; clypeus 

 short, with sparser punctures than between eyes, its suture 

 marked by a conspicuous, transverse, subgranular elevation, 

 sides rounded, front truncated, but angles widely rounded off. 

 Antennae eight-jointed. Prothorax with sides strongly 

 produced outwards, hind angles widely rounded off, the front 

 ones subrectangular; median line vague; with fairly dense 

 but rather small .punctures. Elytra with not very dense and 

 rather small punctures, becoming smaller on sides and 

 posteriorly; geminate-striae scarcely traceable. Hind parts 

 with dense, small, shallow punctures. Front tibiae strongly 

 tridentate (the front tooth unusually thin and curved) ; basal 

 joint of hind tarsi much longer than second. Length, 6 mm. 

 Hab. — South Australia : Ooldea. Type (unique), I. 7832. 

 Belongs to Group 17, hitherto consisting of but one 

 known species fcriniger), from which this species differs in 

 being much smaller and differently clothed, sides of prothorax 

 angularly produced, etc. As viewed from the side the base 

 of the clypeus appears to be traversed by a prominent ridge; 

 the elytra of the type are without an apical membrane. 



LlPARETRUS NIGRICLAVUS, 11. sp. 



Black; elytra (base, suture, and margins narrowly 

 infuscated), hind parts and legs (coxae and hind femora 

 black) more or less reddish-castaneous, antennae (club black) 

 and palpi flavous. Sterna moderately, abdomen (including 

 hind parts) more sparsely clothed; upper-surface glabrous 

 except for a fringe of dark hairs on each, side, and one across 

 apex of pronotum.
