720 NEW SPECIES OF AUSTRALIAN COLEOPTERA, xiv., 



rather dense punctures, slightly larger on pygidiurn (where they 

 are as large as on pronotuni) than on propygidiuni. Front tibUn 

 strongly tridentate; basal joint of hind tarsi distinctly longer 

 than second. Length, 7 mm. 



Ilab. — Queensland : Cunnamulla (H. Hardcastlei; unique. 



Belongs to Group 8, of Blackburn's Table, but could hardly be 

 associated with L h-identaius, as tlie clypeal teeth are much less 

 acute and less produced: it differs from that species also in the 

 clothing of the pronotum being quite as dense at the base as in 

 front, and in the clothing of the pygidium; the punctures of the 

 pronotum are also sparser and considerably larger. The clothing 

 of the head and base of prothorax is much paler than on most 

 of the prothorax, where it is black or blackish (it is uniformly 

 coloured on Z. pa7'tn(i ens a.nd L. ohhisideiis)] irom L. parvideits h 

 differs also in having the clypeus more conspicuously tridentate 

 (both sexes of that species are before me), and from L. obtusidens 

 in having rather larger punctures (on the elytra as well as on 

 other parts). The antennae are paler than the other reddish 

 parts, but the outer parts of the club are lightly infuscated. The 

 elytra are terminated by an extremely short membrane. 



LiPARETRUS QUINQUELOBATUS, n.Sp. 



(J. Black; elytra, antennye and palpi bright flavo-castaneous, 

 legs of a darker red. Sterna with rather long pale hair, abdomen 

 sparsely clothed, clypeus with a few hairs, a pale fringe on each 

 side of pronotum. and extended on to sides of front margin, rest 

 of upper surface glabrous. 



Head with crowded and small, non-contluent punctures, an 

 irregular row of larger ones near clypeal suture; clypeus with 

 sparser and larger punctures than between eyes, sides strongly 

 narrowed and suddenly incurved near apex, which is strongly 

 and acutely tridentate. Antenn<v? nine-jointed. Prothorax with 

 sides strongly rounded, hind angles widely rounded off, the front 

 ones acute, median line shallow: with dense and sharply defined 

 but rather small punctures. Elytra with rather sparse punc- 

 tures of moderate size, becoming smaller and denser at the sides 

 and apex; geminate-stria? well-defined, apical membrane narrow
