in the handwriting of the late W. S. Macleay, is in the Mac- 
leay Museum. In Masters' catalogue it appears as a manu- 
script synonym of tribulus, but it is neither. It was de- 
scribed in King's Survey II., 1827, app. p. 445. The speci- 
men is a female. Compared with a female of tribulus it 
differs in having the median ргобһогасіс excavation much 
wider and larger, and also with rather strong lateral excava- 
tions, somewhat as in acerbus, but more pronounced; the 
tubercles on the elytra at a glance resemble those of tribulus, 
but differ essentially in the absence of a conjoined pair at the 
summit of the posterior declivity, the tubercles at the apex 
of the first row (on the third interstice) are large, and appear 
to be sutural, but a brief look is sufficient to truly locate them.

ETHEMAIA APICALIS, n. Sp. 
Black; antennæ and tarsi dull red. Densely clothed with 
muddy grey scales. Prothorax with blackish sete marking 
position of punctures; elytra with pale setze, sparse on alter- 
nate interstices, more numerous on posterior declivity, and 
rather dense on tubercles; legs with whitish setze. 
Head and rostrum slightly convex, the convexity appar- 
ently caused by two almost concealed ridges. Rostrum short, 
between antenne and eyes subquadrate, near mandibles vis- 
ibly punctate. JProthoraw subeylindrical, slightly narrower 
at apex than at base, feebly longitudinally impressed along 
middle and near sides; sides feebly transversely impressed 
about the middle; densely and coarsely punctate, punctures 
entirely concealed by scales. Elytra much wider than pro- 
thorax, sides subparallel to near apex; shoulders rounded, 
somewhat  thickened; seriate-punctate, punctures large, 
round, entirely concealed by scales; third, fifth, and seventh 
interstices distinctly raised, the third and fifth with a dis- 
tinct conical tubercle at summit of declivity, the fifth with 
an additional smaller tubercle before summit; a small but 
very distinct truncate tubercle on each side of apex. U nder 
surface with large concealed punctures. Tibie tipped with 
black setæ, third tarsal joint feebly bilobed above, entire be-
