Mr. F. P. Pascoe on some new Australian Longicornia. 235 
I have received whilst these sheets were passing through the press, 
I propose to describe and figure hereafter) is a still narrower form, 
with slender, scattered, erect hairs, not stiff and decumbent as in 
the above-mentioned genera, and differing from them essentially in 
the greater size and length of the basal joint of the antennxe, which 
is nearly twice as long as the third, instead of being shorter, or at 
most only equal to it. This species I have named Bebius filiformis. 
‘The following species is a true Jsalium. 
Tsalium Odewahnii. 
I. testaceo-brunneum ; prothorace lateribus rotundato ; elytris nigro-sub- 
bifasciatis, apice intus truncatis, sutura spina brevi producta. 
Hab. South Australia (Ji. Odewahn.) 
Testaceous brown, with sparse white setulose hairs; head coarsely 
impressed, dark chestnut, the hairs more closely set between the eyes, 
so as to form a white spot; prothorax broader than the head, rounded 
at the sides, with confluent coarsely impressed punctures, each having 
a stiff hair arising from its base, the disk with six white spots, formed 
by closely crowded hairs, two on each side, one at the apex and another 
at the base; scutellum covered with white hairs; elytra much broader 
than the prothorax, coarsely punctured, each puncture with a white 
hair, the apex of each truncate internally, the suture produced into a 
short spine, at the shoulder and extending obliquely backwards an 
nregular black band, behind the middle a second band, but transverse 
and very irregular; body beneath brownish testaceous, with spots of 
white hairs on the abdomen; legs and antennz pale brownish, the tips 
of the femora black. Length 11 lines. 
This species resembles J. thoracicum, Pasc., but differs in the 
rounded, not straight, sides of the prothorax, and in the truncate 
apex of each elytron, not rounded as in that species. J. scutellatum, 
Hope, has the apex of each elytron rounded andentire. J. cretiferum 
of the same author (constituting his genus Coptopterus) has the apex 
of each elytron emarginate. 
OpsIpoTa. 
Caput antice brevissimum, tuberis antenniferis basi approximatis. Oculi 
perampli, valde emarginati. Antenne corpore longiores, scapo subcur- 
yato obconico, articulo tertio paulo breviore, quarto fere sequali, cieteris 
longioribus et subequalibus, omnibus, primo et secundo exceptis, uni- 
lateraliter dilatatis. Palpi breves, incrassati. Prothorax sequalis, late- 
ribus rotundatis. Hlytra subbrevia, parallela, depressa, apice integra. 
Pedes mediocres ; femora compressa. Pro- et meso-sterna simplicia. 
In its very short face this genus agrees with Didymocantha, Newm.
