Leffg {^) iitout ; femora having scattered hair.s over their sur- 

 face ; anterior thick, not channelled l^elow ; anterior tibiae strongly 

 notched on inner side , tarsi short ; a few hairs on upper surface ; 

 anterior lightly dilatate, not squamulose below, fourth joint small, 

 transverse, hai-dly emarginate ; ungues finely serrate ; posterior 

 coxfe divided. 



The species on which this genus is founded might perhaps he 

 more correctly placed among the Lebiini ; but it has altogether 

 the appearance of a Helluonide and seems to me, although the 

 labium is coriaceous, to be more in its natural position as placefl 

 above. It is such a distinct species in many ways that it can 

 hardly be confused with any of the previously described Australian 

 Truncatipenn''s. 



Lestiaxthus sculpturatus, n.sp. 



Small, robust ; elytra depressed ; head, prothorax and elytra 

 punctate and bearing numerous scattered long hairs ; head con- 

 stricted posteriorly to a short neck ; prothorax with a strong 

 acute projection on ej^ch side a little before the base ; elytra 

 striate. 



Uppersurface of a very dark l)lue colour, hardly metallic (elytra 

 dark violet) ; undersurface black, shining ; mesosternum, meta- 

 sternum and coxa? piceous ; femora, tarsi and antennie darker than 

 coxfe ; tibia? testaceous, with base and apex piceous. Head large, 

 punctate ; occiput smooth ; front obsoletely bi-impressed ; eyes 

 deeply set in orbits, not prominent ; orbits swollen behind eyes ; 

 the post-ocular processes as large as the eyes but less prominent, 

 covered with long hairs. Mandibles short, projecting but little 

 beyond labrum. Prothorax convex, punctate, a little broader 

 than long (1 x 1-3 mm.), widest before the middle ; sides lightly 

 I'ounded anteriorly, strongly sinuate posteriorly to form the strong 

 angular projection on each side in front of the base, not oblique 

 behind these projections and meeting the base at right angles ; 

 anterior margin lightly and widely emarginate ; anterior angles 

 obtusely advanced ; base truncate ; lateral margin wide ; lateral
