not iu tlio least tliickt'iicd ; elytra with llie lines between each double 

 row ot'punetures more raised, the punctures (more nearly equal in size) 

 and the lines themselves gradually disappiMiring towards the shoulder; 

 colour a didl black, without any tingo of brown. 



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

 tlie members of a genus so closely allied as they ai'c in Melambia, 

 this cannot be assumed until we obtain intermediate forms. 



Brontes [Cucujidtcj. 

 Fabricius, Syat. Eleuth. ii. p. 07. 



Brontes lucivs. 



B. ferrugineus, setulosus; prothorace lateribus denticulatis, dente antieo 

 incrassato ; elytris striato-punctatis, marginibus infuscatis. 



Hab. Sydney. 



Ferruginous brown, covered with short, dark, setulose hairs ; head 

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

 antennae 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 triangidar 

 tooth ; scutellum transversely pentagonal ; elytra clo.sely punctate- 

 striate, becoming gi'adually darker towards the sides ; legs pale fen-u- 

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

 lines. 



Brontes nigricans. 



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

 elytris striato-punctatis, nigricantibus. 



Hab. 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 four next together; prothorax 

 broadly elongate, rugose, slightly punctated, the sides equally denticu- 

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

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

 dark brown ; legs feiTuginous ; body beneath dull ferruginous, closely 

 punctured. Length 4 lines. 



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 miJitari.^, Er., 

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

 differently punctured, &c.
