240 Mr. F. P. Pascoe on some new Australian Longicornia. 
gular; scutellum scutiform ; elytra rather broader than the prothorax, 
finely punctured, with two raised lines at the base, the apex rounded 
externally, but with a short tooth internally at the suture, a broad 
yellow band occupying, except just across the scutellum, rather less 
than the basal third; the pectus black, hairy; abdomen steel-blue; legs 
black, except the distal portions of the femora and proximal of the tibize 
of the anterior and intermediate pairs, which are bright yellow. Length 
8 lines. 
Akiptera was founded some years ago by Mr. W. Wilson Saunders 
for a very rare insect; indeed I believe only one specimen is known, 
which is now in the Melley Collection at Geneva. The species de- 
scribed above differs from Mr. Saunders’s specimen in the form of the 
prothorax and in certain discrepancies in colour. I have drawn up 
the following diagnosis of the genus that its characters may be con- 
trasted with those of allied genera, the nearest of which appears to 
be Bimia, the antenne, however, very nearly resembling Hesthesis. 
Another species (if it be one, as it only differs in the elytra being 
altogether black) was taken, for the first time, just before Christmas 
last by Mrs. Kruesler at Gawler.
