slightly longer and with a more decided yellowish tinge. A 

 specimen from Gerald ton (which appears to be immature) probably 

 belongs to this species; it has the elytra the colour of dried blood, 

 with the margins and epipleuras and part of the abdomen 

 reddish-testaceous. 



Novius BELLUS, Blackb. 



This species is by no means constant as regards its markings. 

 The (J (I have several pairs which were taken in cop.) is usually 

 smaller and darker, the red sutural marking is frequently abbrevi- 

 ated, and sometimes divided into two portions; in the 9 it is 

 often shaped like a New Guinea fish-hook. I have specimens 

 from New South Wales, South and West Australia. Western 

 specimens are usually much darker than eastern ones I have 

 one specimen in which each elytron is supplied with but three 

 (rather small) distinct spots : one close to scutellum, one close to 

 suture just before middle, and one humeral. 



NOVIUS KOEBELEI (Olliff MS.). 



This species was never described by the late Mr. A. Sidney 

 Olliff, but as it is well known in the United States (where several 

 coloured figures of it have been published) Mr. Olliff's name 

 (unless indeed the species should prove to be synonymous with 

 sanguinolentus) will probably stand. I have specimens from the 

 Richmond River.

Rhizobius TRICOLOR, n.sp. 



Elongate, subelliptic. Head, prothorax, sterna, legs (tarsi and 

 knees excepted) black; elytra blue (in places and from some 

 directions with a greenish or coppery gloss); antennae, palpi and 

 abdomen blood-red. Rather densely clothed with white pubes- 

 cence which is waved on the elytra.
