Genera and Species of Coleoptera. 321 



not in the least thickened ; elytra with the lines between each double 

 row of punctures more raised, the punctures (more nearly equal in size) 

 and the liues themselves gi-adually disappearing towards the shoulder ; 

 colour a dull black, without any tinge of brown. 



It is quite possible that this may be only a local variety ; biit, with 

 the members of a genus so closely allied as they are in Melamhia, 

 this cannot be assumed until we obtain intermediate forms.

Hab. Sydney. 



Ferruginous brown, covered \vith short, dark, setulose hairs ; head 

 rather exserted, the vertex somewhat depressed; eyes dark brown; 

 antenupe longer than the body, with a shght greyish pubescence, the 

 first joint nearly as long as the four next together; prothorax rather 

 broadly elongate, covered with numerous large shallow punctures, the 

 sides denticulate, the anterior angle occupied by a strong triangular 

 tooth ; scutellmn transversely pentagonal ; elytra closely pimctate- 

 striate, becoming gradually darker towards the sides ; legs pale ferru- 

 ginous ; body beneath dull ferruginous, closely puuctm-ed. Length 4

Brontes nigricatis. 



B. fuscus; prothorace lateribus denticulatis, dente antico incrassato; 

 eljiiris striato-punctatis, nigi-icantibus. 



Hah. Queensland (Moreton Bay). 



Dark ferruginous brown, covered with short, black, setulose hairs ; 

 head slightly exserted ; eyes dark brown ; antennae longer than the 

 body, the first joint shorter than the fom- next together; prothorax 

 broadly elongate, nigose, slightly pimctated, the sides equally denticu- 

 late, the anterior angle occupied by a moderately thickened tooth ; 

 scutellmn transversely pentagonal ; elytra pimctate-striate, of a uniform

From Brontes denticulatus, F. Smith (also from Australia), the 

 two species described above differ in the comparatively elongate, not 

 transverse, prothorax and other characters. Brontes militaris, Er., 

 is smaller and less robust, narrower prothorax, differently coloured, 

 differently punctured, &c.
