A subopaque dingy species, close to the preceding one on a greatly reduce;d 

 scale, but apart from size, differs in being paler, head slightly longer, eyes 

 smaller, and third joint of antennae as well as the following ones to tenth 

 transverse. The comb on each front femur is rather looser than on that species, 

 and the three on each front tibia are composed of slightly longer teeth, which 

 on the first and second, touch, or slightly, overlap, the base of the second and 

 third. D. australiae and D. torrensensis are also much larger species, although 

 much smaller than the preceding one. The punctures are as I have described 

 them in the preceding species, but the insect being very much smaller, they are 

 less clearly visible under a lens ; the front part of the prosternum is also finely 

 transversely strigose. The general appearance of the insect is strikingly close 

 to Scopaeus flavocastaneiis (of which both sexes are known), but the front 

 legs are at once distinctive, the antennae are also stouter, with most of the joints 

 transverse.

Lathrobium australicuM, Sol. 



Blackburn referred this species to Dicax,^^^ but I think it should remain in 

 Lathrobium; its head is almost exactly as in L. ferreum, not as in the species 

 of Dicax. 



Lathrobium gratellum, Fvl. 



Dolicaon elongatulus, Macl. 



Specimens that were compared and agree with the type of Dolicaon 

 elongatulus, agree perfectly with the description of L. gratelluni, except that 

 they are somewhat larger, 5-5.75 mm. Fauvel appeared to have doubts as to 

 gratellum really being distinct, but thought the description of the prothorax 

 of elongatulus did not fit it. Macleay described it as "considerably longer than 

 the breadth"; Fauvel as "tertia parte longiore quam latiore." Although Macleay's 

 name was published before Fauvel's, the latter's name must stand, as elongatulum 

 was used by Kraatz for a species of Lathrobium in 1858. 



Lathrobium angusticeps, Fvl. 



L. semifumatum, Lea, var. 



Two specimens from Stewart River (Queensland), and one from Sydney, 

 agree with the description of angusticeps ; they are structurally identical with
