354 =Mr. F. P. Pascoe on some new Australian Longicornia. 
little greyish spots, coarsely and rather more remotely punctured com- 
pared with H. marginicollis, and more generally, especially at the sides, 
compared with H. Germari; body beneath and legs blackish, covered 
with a pale ashy pile ; the centre of the abdomen glabrous, glossy black. 
Length 5 lines. 
The triangular outline of the elytra and the longer antennx, more 
especially due to the greater length of the scape and third joint, 
will distinguish this species from the above and H. marginicollis. It 
may be noticed here that the prothorax of the latter appears to be 
always subquadrate, the lateral spine only slightly breaking the 
parallelism of the sides; while in the two species now described 
there is a very marked expansion of the sides from the anterior 
margin to the spine, which is more towards the base. Besides these, 
T have four more forms, each represented by a single specimen, which 
appear to be tolerably distinct ; but, with such materials, it would be 
hazardous to describe them*. 
AMEIPSIS. 
Caput antice quadratum, convexum, tuberibus antenniferis validis, elevatis, 
basi approximatis. Ocul: late emarginati. Antenne corpore longiores, 
scapo subcylindrico, basin versus attenuato, articulo secundo brevissimo, 
tertio parum longiore, tribus sequentibus longissimis sed gradatim de- 
crescentibus, czeteris multo brevioribus. Prothorax quadratus, in- 
wqualis, lateribus fortiter spinosis. Elytra brevia, lateraliter subito 
deflexa et carinata. Pedes eequales; tarsi breves, subdilatati; acetabula 
antica’ leviter angulata. Prosternum paulo elevatum, postice rotun- 
datum. Mesosternwm muticum. 
This genus is closely allied to Acanthocinus? plumula, Newm., 
since referred to Hebecerus, but recently separated by M. Thomson 
under the name of Probatodes. It will, however, be easily distin- 
guished by the shorter elytra bent down at a right angle at the 
sides, the angle forming a very marked and prominent carina. The 
shortness of the third joint of the antenne in both genera is very 
remarkable. 
Ameipsis marginicollis. 
A. nigra, subnitida, pube alba maculata; prothorace lateribus griseo 
vittatis. 
Hab. New South Wales? (Mr. Macleay). 
* A species long known in collections under the name of Hebecerus sparsus, 
Reiche, appears, as far as I can ascertain, to be undescribed. It may be known 
by the lateral spine of the prothorax being more central, the moderately elevated 
lines on the elytra, which are uniformly speckled with white, and the pubescence 
beneath generally diffused, with small glabrous spots at irregular intervals. It 
is from Western Australia.
