XVIII.—Descriptions of some New Australian Longicornia. 
By Francis P. Pascoz, F.L.S. 
Some months ago I described, in the Transactions of the Entomo- 
logical Society, sixty new species of Australian Longicornia. Through 
the kindness of Fred. Geo. Waterhouse, Esq. of Adelaide, of Mrs. 
Kruesler, and Mr. Johannes Odewahn, of Gawler, South Australia, I 
am now enabled to make an addition of forty more. This brings the 
number of Australian Longicornia up to above 400 species. There 
are still remaining several others in my collection, belonging princi- 
cipally to the genera Macrotoma, Hesthesis, and Mallodon, which pre- 
sent certain difficulties that can only be cleared up by the examina- 
tion of more numerous specimens than I have yet been able to 
obtain. In Mallodon, for instance, there are some examples related 
to M. figuratum differing from each other in size, and to a certain 
extent in outline (as indeed individuals even of the same species may 
be expected to do among this portion of the Prionid), in punctura- 
tion, and in various particulars connected with the head and pro- 
thorax. Whether any of these are sufficiently constant in their 
characters to deserve specific distinction remains to be seen. There 
are three, however, belonging to this genus which are so decidedly 
dissimilar to every other species and to each other, that I have no 
hesitation in adding them to the list. I hope eventually to have 
sufficient materials to work out the genus and its ally Macrotoma, 
so far as the Australian species are concerned, in a more satisfactory 
manner. In the meantime [ shall be glad if these remarks elicit 
attention from those who may be able to assist me.
