be merely sexual, I. dispar being, as indicated above, very 
closely allied to, and superficially very like, several previously- 
described species, whereas the present one, in respect of its 
general appearance, is one of the most distinct species of the 
genus, and its structural characters are very different from those 
of M. dispar. 
N.S. Wales ; taken about the Tweed R. (Tamworth, &c.) by 
Mr. Lea. 
M. quadraticollis, sp. nov. Fem. Sat angusta, postice latior ; 
picea, antennaruin scapo et pedibus (genubus tarsisque 
exceptis) rufis, elytris (basi excepta) rufescentibus ; squamis 
piliformibus albidis disperse vestita ; rostro quam prothorax 
paullo longiori, arcuato, nitido, apicem versus (a latere viso) 
subacuminato; antennis pone rostri medium insertis; funiculi 
articulo basali quam sequentes 3 conjuncti paullo breviori ; 
prothorace leviter transverso, subquadrato, antice parum 
angustato, pone marginem anticum transversim leviter 
impresso, sat grosse punctulato ; elytris sat fortiter punctu- 
lato-striatis ; prosterno ante coxas modice elongato, parum 
emarginato. Long. (rostr. inel.), 14 1.; lat., 2 1. 
Nearest to M. submetallica, Blackb., but without any metallic 
scales and with the prothorax very much less narrowed towards 
the front. The elytra also (in the unique example before me) are 
very differently colored, being pitchy black at the base, and 
becoming a little reddish in the posterior two-thirds of their 
length. 
S. Australia ; near Quorn. 
BAGOUS. 
B. clarenciensis, sp.nov. Rufus, vertice rostri basi corpore subtus 
et tarsis piceis ; rostro quam prothorax (maris vix feminze 
sat manifeste) longiori ; prothorace pone apicem sat fortiter 
constricto ; elytris striatis, interstitiis leviter convexis. 
Long. (rostr. incl.), 1 1. (vix) ; lat., 2 1. (vix). 
Easily recognisable among its described congeners by its very 
small size and the bright brick-red color of its whole upper 
surface except the head and the extreme base of the rostrum. 
N.S. Wales ; taken at the Clarence River by Mr. Lea.

£. bispinosus, Boisd. I have an example of this species from 
tropical Queensland. I think it has not been previously recorded 
as occurring in Australia.
