of the male much more widely apart. Compared with &. major, 
Blackb., it is much more finely punctulate. 
Queensland ; taken near Port Mackay. 
R. gosfordensis, sp. nov. Elongato-ovalis ; sat convexus, elytris 
pone scutellum fere subgibbosis, sat nitidus ; pallide fulvo- 
pubescens et setis erectis sparsim vestitus; rufescens, pro- 
thorace (margine antico et laterali anguste dilutiori excepta) 
fere nigro, elytris femoribusque picescentibus ; capite pro- 
thoraceque minus fortiter subcrebre, elytris vix fortiter sat 
crebre, punctulatis; his in spatio communi paullo pone 
scutellum posito sublevibus; prosterno medio longitudina- 
liter depresso ; spatio depresso minus lato, antice sat angus- 
tato, utrinque subtiliter carinato. Long., 1,4 1.; lat., 125 1. 
(vix). 
This species is very near . speculifer, Blackb., beside which 
it must stand in my tabulation of the genus. It is a notably 
narrower and more elongate insect with its elytral puncturation 
distinctly less strong. 
N.S. Wales; taken by Mr. Koebele near Gosford. 
R. discipennis, sp. nov. Breviter late ovalis; valde convexus, 
elytris pone scutellum fere subgibbosis; sat nitidus ; pube 
albida suberecta et setis longioribus magis erectis vestitus ; 
niger vix subeneus (nonnullis exemplis rufescentibus) an- 
tennis palpis tibiis tarsis abdomineque dilutioribus (nonnul- 
lorum exemplorum pedibus totis, vel etiam corpore subtus 
toto, pallidis); capite crebre distincte, prothorace crebre 
sat aspere, elytris sparsius subfortiter, punctulatis ; his in 
spatio communi paullo pone scutellum levibus, hoc spatio 
utrinque puncturis fortiter impressis lineatim positis mar- 
ginato; prosterno medio longitudinaliter depresso; spatio 
depresso antice acuminato, utrinque subtiliter carinato, 
Kong 15 lat, 2 1. 
In my tabulation this species must stand with the preceding 
species /R. gosfordensis) and R. speculifer from which it is at 
once distinguishable by the common unpunctured space on its 
elytra being bordered on either side by a well-defined line con- 
sisting of some of the largest punctures on the elytra. 
N. Queensland ; taken by Mr. Koebele near Cairns. 
R. eminens, sp. nov. Sat late ovalis; fortiter convexus; sat 
nitidus ; setis subtilibus sat elongatis erectis vestitus ; rufus, 
elytris lete ceruleis, sterno medio subinfuscato ; capite sub- 
crebre sat fortiter, prothorace vix crebre sat fortiter, elytris 
sparsim fortiter, punctulatis ; his in spatio communi paullo 
pone scutellum levibus, hoc spatio utrinque puncturis 
lineatim positis marginato ; prosterno medio longitudinaliter
