markably strong ; saving a fringe of rather close-set hairs run- 
ning round the external margins, it is almost glabrous.

A. occidentalis,sp. nov. Pallide piceo-rufus; sat nitidus; vix pube- 
scens ; capite crebre sat fortiter punctulato inter oculos vix 
depresso ; antennis valde dilatatis, articulis 2°, 3°, 4° que ex 
ordine paullo latioribus, ceteris 4° latitudine eequalibus quam 
longioribus circiter quater latioribus, ultimo praecedentibus 2 
conjunctis sat quali ad apicem late rotundato ; prothorace 
quam longiori circiter quarta parte latiori, fortius sat crebre 
punctulato, late leviter canaliculato, latitudine majori longe 
ante medium posita, lateribus antice modice arcuatis postice 
vix sinuatis, angulis posticis rotundato-rectis vix explanatis ; 
elytris crebre subtilius punctulatis, utrinque ad angulos 
suturales apicales fovea magna obscura obsolete impressis, 
apice late membranaceo postice obsolete tridentato ; pygidio 
crebre subfortiter punctulato ; tibiis sat fortiter dilatatis, 
anticarum apice triangulariter inciso (incisure angulis 
utrisque valde acutis), posterioribus 4 ad angulum apicalem 
externum breviter oblique truncatis. Long., 5 1; lat., 14 1. 
The pubescence is much like that of the preceding species, but 
the lateral fringes are less distinct. The membranaceous apex of 
the elytra is almost truncate, but when closely examined it is seen 
to be feebly prominent in an angular fashion at the middle and 
on either side.

C. Melbournense, sp. nov. Ovale; sat nitidum ; fulvo-pubescens ; 
piceum, elytris basin versus rufescentibus, antennis basi 
apiceque et pedibus testaceis; prothorace transverso dis- 
tincte punctulato, angulis posticis obtusis; elytris ut pro- 
thorax punctulatis, stria suturali distincta; femoribus 
posticis (maris) late distincte dentatis. Long., 11. 
The antennz are about as long as the prothorax, joints 7-10 
infuscate, the rest testaceous; joints 1-3 about equal in length, 
1 and 2 stouter than 3, 4 shorter than 3, not quite so wide as 
long obconic; 5 slightly wider, not longer than wide; 6 strongly 
transverse, 7 very strongly transverse (about three times as wide 
as long), scarcely so long as 6; 8-10 not differing much nter se 
(evidently wider than and about twice as long as 7), 11 conic, 
evidently longer than 10. The mesosternum is strongly carinate. 
Compared with the European C. brunneum, Latr., this species 
is more oval and less closely punctulate. 
Victoria; near Melbourne.
