summit: apex rounded. Under surface with punctures trace- 
able. Leys moderately long ; femora thickened ; third tarsal 
joint bilobed, fourth shorter than three preceding combined. 
Length, 33; rostrum, 1; width, 14 mm. 
Hab.—Swan River. 
A small and very distinct species, possibly belonging to 
M edicasta, but I prefer to regard it as an Ethemaia. 
ETHEMAIA SELLATA, Pasc. 
An abundant and widely distributed species. I have taken 
specimens at Tamworth, Queanbeyan, Hay, and other places 
in N.S.W., Murray Bridge and Adelaide in S.A., Beverley 
and Pelsart Island in W.A., and Hobart, Franklin, and 
Launceston in Tasmania. 
The semilunar brown marking on the elytra mentioned by 
Mr. Pascoe is rarely present, the scales nearly always being 
of an uniform colour. The size (including rostrum) ranges 
from 5% to 91 mm. 
E. ANGUSTICOLLIS, Pasc. 
Hab.— Clarence River. 
HYPHÆRIA ASSIMILIS, Pasc. 
Hab.—Queanbeyan. 
A specimen from Wilcannia differs in having a spot of 
white scales on the apex of prothorax, the scutellum white 
and connected with the prothoracie spot by a feeble whitish 
median line; the elytral tubercles are also more densely 
crowned and with paler scales than on the rest of the sur- 
face. 
MEDICASTA LEPTOPSOIDES, n. Sp. 
Black; antenne, tibiæ, and tarsi obscure red. Densely 
clothed with muddy-brown or slaty-grey scales, paler on under 
than on upper surface. Legs with short, whitish sete. 
Head somewhat flattened. Rostrum about twice as wide 
as long, narrower than head, with traces of about five feeble 
ridges. Prothoras cylindrical, slightly longer than wide, 
base and apex equal, with large punctures almost concealed 
by clothing. | Elytra wider than  prothorax, shoulders 
rounded, sides feebly increasing to near apex; seriate-punc- 
tate, punctures large, round, almost concealed; third, fifth, 
and seventh interstices strongly raised, the third with a dis- 
tinct tubercle at summit of posterior declivity, fifth with a 
tubercle just before and another just below summit. Punc- 
tures of under surface entirely concealed. Tarsi with third 
joint deeply bilobed, fourth slightly shorter than three pre- 
ceding combined, subtriangularly dilated to apex. Length, 
3$ ; rostrum, 2; width, 14 mm. 
Hab.—W.A.: Pinjarrah.
