with a conspicuous but rather shallow median line becoming 

 deeper at base ; with punctures of moderate size, and rather 

 sparse about middle, but more numerous towards sides. Elytra 

 rather more dilated posteriorly than usual;- punctures of 

 moderate size and comparatively sparse; geminate-striae well- 

 defined. Front tibiae strongly tridentate ; basal joint of hind 

 tarsi much shorter than second. Length, 6-8 mm. 



Hab. — Western Australia: Lake Austin (H. "W. Brown). 

 Type, I. 7841. 



The pronotum is conspicuously frilled on all its margins, 

 and on some specimens there are a few long hairs on the 

 middle of the disc; as the basal joint of the hind tarsi is 

 distinctly shorter than the second, the species should evidently 

 be referred to Group 2, but its small size and conspicuously 

 squamose hind parts cause it to look very out of place there ; 

 if not to Group 2, it might be referred to Group 3, and there 

 associated with angulatus, which has the clypeus of the male 

 much more angular, hind parts not squamose, etc. The 

 punctures of the hind parts are normally mostly concealed, 

 but appear to be fairly numerous; parts of the upper-surface 

 are rather brightly iridescent. The female is larger than the 

 male, with margins of clypeus less elevated, front more 

 rounded, and legs somewhat shorter. On all the specimens 

 (eight) before me the elytra are without a membranous fringa 



LlPARETRUS TRICHOSTERNUS, n. Sp. 



PI. xxxvii., fig. 120. 



d • Black ; elytra (base infuscated) and antennae (club 

 black) of a more or less dingy-castaneous. Clothed with 

 long, whitish hair (but becoming dark on pronotum), part of 

 pronotum and elytra (except at base and sides) glabrous, hind 

 parts (in addition to the long hair) with rather dense, 

 depressed, white scales. 



Head with crowded and confluent punctures, becoming 

 somewhat larger and much sparser on clypeus; the latter 

 with ^strongly elevated sides and front, sides oblique and 

 curved, front distinctly emarginate, antennae nine-jointed. 

 Prothorax with sides rather strongly rounded, hind angles 

 widely rounded off, front ones produced and acute, median 

 line rather shallow but distinct at base; punctures of uneven 

 sizes and unevenly distributed. Elytra with fairly large 

 punctures about base, becoming much smaller posteriorly; 

 geminate-striae distinct. Front tibiae tridentate; basal joint 

 of hind tarsi shorter than second. Length, 6J-6J mm. 



9 • Differs in having wider elytra, clypeus with less 

 elevated sides and front, the latter not emarginate and legs 

 shorter, with front tibiae more acutely tridentate.
