Mr. F. P. Pascoe on some new Australian Longicornia. 243 
the larger ones confluent, no smooth spaces; scutellum subscutiform, 
slightly pointed behind, nearly impunctate, an irregularly impressed 
line near the margins on each side; elytra with numerous coarse but 
very shallow punctures; body beneath covered with golden-brown 
hairs, especially on the abdomen, where they are long and very dense, 
the antepectus nearly glabrous, except around the prosternum; legs 
glossy brown, glabrous, with a few distinct punctures ; tibiz unarmed. 
Length 24 lines. 
A fine and very distinct species, which it is quite unnecessary at 
present to compare with any other. 
Mallodon jejunum. 
M, parallelum ; prothorace transverso, antice incurvo, lateribus vix cre- 
natis, marginibus angustissimis, disco eroso-punctato, spatiis duabus 
glabris triangularibus exceptis ; antennis vage punctatis, scapo triquetro. 
Hab. Richmond River. 
Narrow and, including the prothorax, nearly parallel, chestnut-brown, 
the elytra testaceous brown; head narrower than the prothorax, coarsely 
punctured, punctures mostly confluent ; mandibles short and thick, with 
large remote punctures; antenne about half the length of the body, very 
slender, except the scape, smooth, slightly and remotely punctured, the 
scape short and triquetrous, and rather closely punctured ; prothorax 
transverse, the anterior margin incurved, the side with a very narrow 
border, which is only very slightly crenate, a sharp spine nearly parallel 
with the side at the posterior angle, which is opposed to another poste- 
riorly nearly at a right angle to it, the disk with a small smooth trian- 
gular space on each side anteriorly ; scutellum finely punctured, some- 
what triangular, its apex rounded ; elytra with crowded punctures, with 
several often confluent together; body beneath nearly glabrous, the 
metasternum only covered with long silly hairs; legs rather short, 
glabrous, the intermediate as well as the anterior tibize spined. Length 
14 lines. 
The narrow parallel outline, slender antenne with a triquetrous 
scape, armature of the prothorax, &c., are sufficiently distinctive of — 
this species at present. 
Differing from Mallodon in the greater length of the third antennal 
joint, which considerably exceeds the scape, and in this respect agree- 
ing with Macrotoma, but with the head in the male nearly as broad as 
the prothorax, is a species for which I think a new generic name will 
be necessary. This I have provisionally named Catypnes ; but at pre- 
sent I shall not attempt to characterize itfurther. If Chiasmus and 
Archetypus are to be retained, still more genera will have to be formed 
out of the old Mallodon. I received my specimens from W. Macleay, 
Esq., M.L.A., of Sydney. °
