H, Adelaide, sp. nov. Ovalis; sat elongata; sat nitida ; supra 
nigra; subtus picea, antennis pedibusque rufescentibus, 
femoribus (preesertim posticis) plus minusve infuscatis vel 
nigricantibus ; capite lato, in medio fere levi, inter oculos 
suleato; antennis sat robustis, quam corporis dimidium 
paullo longioribus, articulo 3° quam 4" multo longiori, hoc 
quam 2" subbreviori; prothorace fortiter transverso, 
antice vix angustato, distincte minus crebre punctulato, 
fortiter transversim  sulcato, lateribus leviter arcuatis, 
angulis minus acutis (anticis incrassatis extrorsum leviter 
directis) ; elytris crebre fortiter punctulatis ; tibiis inter- 
mediis breviter distincte mucronatis. Long., 1} 1.; lat., 41. 
(vix). 
A very distinct species on account of inter alia its entirely 
black upper surface.

HALTICA. 
This genus as restricted by Dr. Chapuis may be taken to be 
limited to species that M. Allard’s monograph would place in 
Graptodera. M. Allard suppresses Haltica altogether, but Dr. 
Chapuis’ plea for retainining the name seems to me quite con- 
clusive. The species are extremely variable and very difficult to 
determine. As regards the Australian species the best distinctive 
characters appear to me the sexual peculiarities of the males. 
H. corrusca, Er. I am not sure that I know this species 
(which was described from Tasmania). The only Tasmanian 
Haltica known to me differs in important respects from Erich- 
son’s description. But there is a species occurring plentifully, 
and widely distributed in Southern Australia (Victoria, N.S. 
Wales and 8. Australia, and probably in Tasmania), which agrees 
well with the description of //. corrusca in every respect except 
that (so far as regards the specimens I have seen) the violaceous 
coloring of the underside referred to by Erichson is wanting. It 
is an insect of brassy-zenous color (long., about 23 1.) with well 
defined fairly close and rather fine elytral puncturation, and the 
longitudinal post-humeral sulcus very faint. Its males (apart 
from the dilatation of the basal joint of the tarsi) are dis- 
tinguished by the sculpture of the apical ventral segment, which 
is devoid of tubercles and has its apical half (or thereabouts) 
flattened so as to be on a lower plane than the front part from 
which in certain lights it seems to be separated by a sulcus; the 
middle part of its apical margin (which must not be confused 
with the free edge of the pygidium seen beyond it) is rounded 
but owing to inzequalities on its surface immediately before the 
apex it appears (from a point of view whence the true apex does
