above it appears to be feebly incurved to the middle, and 

 from behind (seen just above the head) it is scarcely per- 

 ceptibly trilobed. There was no locality label on the type, but 

 it was probably from Queensland or the Northern Territory. 



LlPARETRUS MIMICUS, n. sp. 



Black; elytra, hind parts, and parts of legs dark piceous- 

 brown, tarsi, front tibiae, antennae (club excepted) and palpi 

 paler. Sterna with rather dense long pale hair, becoming 

 sparser and more setose in character on abdomen; upper- 

 surface and hind parts glabrous, except for a fringe of dark 

 hair on each side of pronotum. 



Head with small dense non-confluent punctures; clypeal 

 suture unusually deep; clypeus short, with somewhat larger 

 but not much sparser punctures than between eyes, sides 

 strongly oblique and gently rounded, front truncated, with 

 angles rounded off. Antennae eight- jointed. Prothorax with 

 sides strongly rounded posteriorly ; hind angles widely rounded 

 off, the front ones produced and acute ; median line vague ; 

 punctures rather small and sparse. Elytra with moderately 

 large but not very dense punctures; geminate-striae well- 

 defined. Hind parts with dense punctures, rather larger 

 than on pronotum, the propygidium with a rather large but 

 obtuse median tubercle. Front tibiae tridentate, but the 

 tooth nearest the base very small (the others large) ; two basal 

 joints of hind tarsi equal or subequal. Length, 6 mm. 



Hab. — South Australia: Mount Lofty (S. H. Curnow). 

 Type (unique), I. 7858. 



The type does not fit well into any of Blackburn's 

 divisions of Group 16, as its elytra, although dark, are not 

 black, but regarding them as black it would be associated with 

 erythrojrygus, from which it differs in many respects (size, 

 colour, punctures, etc.). When the full length of the two 

 basal joints of the hind tarsi is visible, the first is seen to be 

 a trifle longer than the second (certainly not "much" 

 longer) (1& ), but from some directions it appears to be a trifle 

 shorter; it is the only member of Group 16 (except falla-x, 

 which extends as far south as Oodnadatta) known from South 

 Australia. In general appearance it is strikingly close to 

 rotundipennis (of Group 13), to some of gracilipes (of Group 

 7), and to some of picipennis (of Group 4). I have satisfied 

 myself by careful examination of the antennae from different 

 positions and in good lights that they are but eight- jointed ; 



(18) Group 17, the group with the basal joint much longer 

 than the second, consists of but one species (criniger), very 

 unlike the present one.
