1 492 FURTHER NOTES ON AUSTRALIAN COLEOPTERA, 
lobed backward all across ; the testaceous margin on either side is 
wider than the black central portion ; under a powerful lens the 
surface is seen to be lightly and sparingly punctulate and to 
bear on either side near the margin an oblicjue furrow running 
forward from the base, the portion outside this furrow Vjeing tumid. 
The scutellum is minute and strongly transverse. The elytra are 
at their widest in front of the middle where they are a third again 
as wide as the prothorax, of which they are about four times the 
length ; they are l ather attenuate towards the apex and are very 
strongly and sinuately contracted externally from a little behind 
the shoulder (apparently in order to accommodate the enormously 
developed hind femora). Their puncturation resembles that of 
the prothorax but with the addition here and there (especially 
towards the sides) of some rather stronger punctures. The anterior 
coxae are strongly prominent, and almost contiguous, with their 
cavities closed behind.* The hind femora are as largely developed 
as in Arsipoda, and are unarmed 3 the hind tibiae are somewhat 
flexuous, and are strongly channelled and denticulate on their 
external margin, and mucronate at their apex ; their tarsi are 
inserted slightly above the apex (feebly after the manner of 
Psylliodes) and have the basal joint equal in length to the remaining 
three together 3 the claws are appendiculate. The basal ventral 
segment is very strongly sulcate down the middle (this latter 
character probably sexual). 
This remarkable little Ilalticid seems to be certainly very close 
to the East Indian Ampliimela (of which I have never seen a type) 
though probably different enough to justify generic separation. 
Its agreement with Ampliimela in the extraordinary position of its 
antennte renders it convenient to refer it for the present to that 
genus which M. Chapuis (its author) regards as constituting a 
distinct “ groupe ” of the Ilalticides. 
A single specimen sent by F. M. Bailey, Esq., and taken by him 
near Brisbane. 
* I feel practically certain that this is the case, although I have not been 
able to dissect a specimen ; the example described is in a fairly satisfactory 
condition for examination.
