Mr. F. P. Pascoe on some new Australian Longicornia. 237 
with a short, strongly impressed mesial line between the eyes, termina- 
ting above the epistome in a broad, transverse depression ; prothorax 
nearly as long as broad, the sides irregular, having rather behind the 
middle a short angular tooth, disk with scattered shallow punctures, 
its sides somewhat slightly corrugated ; scutellum triangular, obtuse at 
the apex; elytra much broader than the prothorax, rather short and 
depressed, the sides nearly parallel, coarsely punctured at the base, the 
punctures becoming nearly obsolete at the apex; pectus transversely 
corrugated; metasternum and abdomen glossy black, nearly impunc- 
tate; legs black ; tibize slightly ciliated internally; antenne black and 
opake, except the basal joint. Length 9 lines. 
Ceresium? modestum. 
C. rufo-testaceum, pube grisea sparse tectum ; prothorace breviter ovato, 
~ medio cicatricoso ; elytris oblongo-oyatis ; femoribus subclavatis, 
Hab. South Australia (Mr. Odewahn). 
Reddish testaceous, covered with short, greyish, scattered hairs; head 
without any mesial line, the eye occupying nearly the whole side; an- 
tenne scarcely two-thirds the length of the body; prothorax shortly 
ovate, a longitudinal scar-like line in the middle; scutellum subtrans- 
verse, rounded; elytra oblong-ovate, narrower in the male, rather 
closely punctured, each puncture with a grey hair arising from its base, 
the apex rounded ; body beneath reddish chestnut, sparsely pubescent ; 
legs rather short, the femora scarcely clavate. Length 4-5 lines. 
If Ceresium raripilum of Newman, the type of the genus, is to be 
strictly defined (which, however, Mr. Newman has not done), this 
species can only be considered as doubtfully congeneric. There are 
several undescribed species which it will be necessary to work up 
before the limits of Ceresiwm can be ascertained. 
Obrium dorsale. 
O. castaneum, nitidum; prothorace, antennis, pedibus elytrisque basi et 
medio luteis. 
Hab. South Australia (Mr. Waterhouse). 
Dark chestnut, shining, with short, scattered, erect hairs ; head roughly 
punctured ; antenne rather longer than the body, pale luteous; pro- 
thorax elongate, irregularly and coarsely punctured, nodose at the side, 
the disk with three rather obscurely defined, smooth prominences; scu- 
tellum triangular; elytra rather narrow, with large, deep, closely set 
punctures, the base and stripe down the suture for about two-thirds of 
its length pale luteous; body beneath glabrous, glossy luteous; legs 
luteous, shining, with long, erect, dispersed hairs. Length 5 lines. 
This species and the following are rather more robust than usual. 
The anterior coxe are also not at all exserted, and their acetabula 
have a long angular slit externally.
