LlPARETRUS BIMACULATUS, 11. Sp. 



PL xxxvii., fig. 130. 



Black, with a bright bluish iridescence; elytra with a 

 large flavous spot on each side near base, front legs, antennae 

 (part of club excepted), and palpi flavo-castaneous. Elytra 

 and clypeus glabrous, but elsewhere with rather long white 

 or whitish hair; abdomen in addition with white pubescence 

 in transverse series. 



Head with rather crowded, small, and moderately large 

 punctures ; clypeus highly polished and with sparse punctures, 

 sides strongly rounded, apex very feebly incurved at middle. 

 Antennae nine-jointed. Prothorax with strongly rounded 

 sides, hind angles widely rounded off, the front ones feebly 

 produced and subacute; with small and comparatively sparse 

 punctures, and a few larger ones scattered about; median 

 line absent. Elytra with sparse and rather small punctures; 

 geminate- striae well-defined ; without apical membrane. Hind 

 parts with rather dense small punctures, and a few of larger 

 size. Front tibiae strongly bidentate ; first joint of hind tarsi 

 just perceptibly longer than second. Length, 5 J mm. 



Hab. — Northern Territory: Darwin (W. K. Hunt). 

 Type (unique), I. 7847. 



In Blackburn's table would be associated with discoidalis, 

 from which it differs in being brilliantly iridescent, prothorax 

 with sparser clothing, punctures distinct and surface not 

 opaque, pale portions of elytra considerably smaller in extent 

 (each spot is close to the base and about the size of the head), 

 and basal joint of hind tarsi shorter. The erect hairs on the 

 disc of the pronotum are not dense, but are almost evenly 

 distributed; on the propygidium there are three transverse 

 series of white pubescence (in addition to the long hair), the 

 first basal (this would probably be concealed on some speci- 

 mens), the second median, and the third apical; at the tip 

 of each elytron there are two long rigid white setae, and on 

 the sides a few shorter ones. 



LlPARETRUS LONGIDENS, 11. sp. 



PI. xxxvii., fig. 131. 



Black and flavo-castaneous. Elytra glabrous, elsewhere 

 more or less densely clothed. 



iZead with crowded but sharply defined punctures in 

 front, becoming sparser posteriorly; clypeus very short, with 

 rather dense punctures, margins lightly elevated, sides very 

 strongly narrowed to apex, which is truncated (but without 

 lateral angles). Antennae nine-jointed. Prothorax with sides 

 rather strongly produced, hind angles widely rounded off.
