Head with rather small and comparatively sparse 

 punctures; clypeus more shining and with sparser punctures 

 than between eyes, its base somewhat elevated in middle, its 

 margins rather strongly raised and semicircular, except for a 

 flattening in front. Antennae nine-jointed. Prothorax with 

 evenly rounded sides, hind angles obtuse but not rounded off, 

 front ones acute and rather lightly produced ; punctures 

 slightly sparser, but otherwise much as on head. Elytra with 

 rather sparse but sharply defined punctures ; geminate-striae 

 conspicuous; with an extremely short apical membrane. Hind 

 parts with punctures much as on pronotum. Front tibiae 

 bidentate, the front tooth long and acute, the second obtuse; 

 basal joint of hind tarsi slightly shorter than second. Length, 

 5-6 mm. 



Hab. — Western Australia: Beverley (F. H. du Boulay). 

 Type I. 7846. 



In Blackburn's table would be associated with rotundi- 

 pennisy from which it differs in being considerabty narrower, 

 sides of prothorax more evenly rounded and base different, 

 clypeus different at base, etc. It is one of the few species of 

 the genus whose hind angles of prothorax (although obtuse) 

 are not completely rounded off; the pronotum is more convex 

 than usual, and except for a slight flattening near the base, 

 is without trace of a median line. When the full extent of 

 the basal joint of the hind tarsi is clearly visible, it is seen 

 to be almost exactly the length of the second (certainly not 

 longer); the sixth joint of the antennae is very small, and 

 so closely applied to the club that the antennae at first appear 

 to be but eight- jointed. Of the five specimens taken by Mr. 

 du Boulay three have the elytra distinctly paler than the 

 prothorax, but the other two have very dark elytra (scarcely 

 paler — to the naked eye — than the prothorax) ; one of the 

 former has the abdomen of a dingy-brown, but on the others 

 it is black or blackish ; the tarsi are usually paler than the 

 rest of the legs. 



LlPARETRUS SEMIFLAVUS, 11. sp. 



Flavous; some parts black or infuscated. Sterna with 

 moderately dense clothing, abdomen with a row of setae 

 across each segment, upper-surface and hind-parts glabrous, 

 except for a conspicuous fringe on each side of pronotum. 



Head with small and dense but (except in front) not 

 crowded punctures ; clypeus with considerably larger punctures 

 than between the eyes, margins rather stronglv elevated, sides 

 rounded and rather gently decreasing in width to apex, which 

 is lightly incurved to middle. Antennae nine-jointed.
