not catch the eye) to be trilobed. Its intermediate tibiz are 
straight or nearly so. 
Hi. splendida, Oliv. I have not seen any insect at all likely to 
be this species; the description of it seems possibly consistent 
with its being a true Haltica. 
Hl. ferruginis, Blackb. I regard this insect as possibly repre- 
senting a gen. nov. near //altica. As far as I know the species 
that may be rightly regarded as typical members of Haltica, they 
are lnvariable in being of some dark (more or less metallic) color, 
and in having a prothoracic sulcus completely traversing the seg- 
ment in complete separation from its base. H. ferruginis however 
not only is of a nearly uniform brownish-testaceous color, but has 
its prothoracic sulcus less distinctly complete than in a typical 
Haltica inasmuch as near the lateral margins it seems to lose itself 
in a mere basal depression (there being in that part no elevated 
interval between it and the true basal margin). The combination 
of these two differences from a normal Haltica points to the 
likelihood of other species allied to it existing in N.W. Australia 
(which is its habitat). Its prothoracic sulcus is not much like 
that of either of the new genera (//yphaltica and Halticodes ) 
characterised above. As far as I can see its four anterior tibi 
are unarmed but the type is not in a condition to allow of my 
thoroughly investigating the question whether a very small mucro 
may be hidden among the apical sete. I cannot find any named 
genus other than //a/tica in which it might be placed, although 
it is very difficult to arrive at certainty regarding some of Baly’s 
genera owing to their author having merely enumerated their 
characters without mentioning what genera they are allied to. 
H. pagana, sp. nov. Ovalis, minus elongata; nitida; ccerulea 
vel purpurea, antennis tibiis tarsisque obscuris ; capite sub- 
leevi, inter oculos transversim sulcato, ante sulcum bituber- 
culato ; antennis quam corpus (maris haud multo, feminez 
paullo magis) brevioribus, sat robustis (articulo basali 
modico, 2° brevi, 3° quam 1" vix breviori, 4° quam 3" vix 
longiori) ; prothorace sat transverso, antice sat angustato, in 
disco levi, latera versus distincte punctulato, ante basin sat 
profunde sulcato, lateribus sat arcuatis; elytris sat crebre 
sat fortiter (quam H. pusilla, Duf., paullo minus crebre vix 
minus fortiter) punctulatis, ad latera obsolete sulcatis (sulco 
ante medium extus vix manifeste carinato). 
Maris tibiis intermediis sat rectis; segmento ventrali apicali 
in medio postice rotundato, nullo adspectu trilobato, mox 
ante apicem bituberculato. Long., 22 1.; lat., 14 1 
Much like H. australis, Blackb., but a more richly colored in- 
sect, with less close elytral puncturation, and the apical ventral
