A single specimen, ^, entirely differing from all the other 

 tufted species, with its strongly raised elytral costse more approx- 

 imate than in any of the costiform species, though nearest to H. 

 Macleayi Breme, in this respect. The yellow markings on the 

 margins may be individual and due to immaturity, but their 

 transparency is due to the thin structure of this part Type in 

 the author's collection. There are two specimens in the French 

 Collection, Melbourne Museum. 



Hel^us French!, n.sp. 



Elongate-ovate, black, very nitid and smooth, antennae and 

 legs piceous, the former with apical joints red. 



Head : labrum evident, epistoma truncate in front, with blunt 

 angles, sides a little raised towards the antennal orbits, limited 

 behind by a straight transverse ridge; behind this the front 

 triangularly raised, the triangle defined by raised impression 

 with apex between the eyes, its base formed by transverse ridge; 

 this triangle depressed in tlie middle. Eyes nearly contiguous, 

 large and oblique. Antennre at rest not reaching base of pro- 

 thorax, third joint less than fourth and fifth combined, 4-7 

 obconic, 8-10 round, eleventh ovoid. Prolhorax transverse 

 (6x8 mm.), circularly emarginate, disc rather flat except at the 

 strongly rai,sed central carina, sides angulately raised, so that 

 (viewed sideways) the outside margins are considerably higher 

 than the discal carina; widest at base (in ^ slightly in front 

 of base), then gradually arcuately narrowing (a little sinuate 

 anteriorly) to apex; anterior processes hollow, terminating in a 

 rounded point, just crossing (in 9 not quite meeting), posterior 

 angles acute, produced backwards into a blunt tooth (viewed 

 sideways, these denticulate angles, though deflexed at the apex,
