Lougicornia of Austraha and Tasmania. 183 
fourth or fifth of the elytra; a short and narrow margi- 
nal band is also present; the under side is of a fine 
lustrous dark green or bluish colour; the legs and 
antenne black. A form similar to this in the pattern of 
the dorsal vitta, but with the head, thorax, legs, and 
antenne of a dull testaceous colour, is represented in 
the Brit. Mus. collection by specimens taken at King 
George’s Sound. 
A further very distinct variety embraces some of the 
examples taken by Mr. Walker at both Hobart and 
Launceston in Tasmania. In these the head, thorax, 
and legs are testaceous, the antenne are somewhat 
darker; while the antenne are entirely of a rather pale 
fulvous colour. This variety is not to be distinguished 
by any structural characters from those referred to 
above; it occurs also in South Australia, one or two 
specimens from which locality exhibit a small dark spot 
at the tip of the elytra, and have the thorax and pos- 
terior part of the head of a brownish testaceous colour. 
Without having seen the type of Pterostenus quietus, 
Newm., I can only suggest that this species may also 
be a variety of P. sutwralis. Such characters given for 
the species as do not relate to colour apply equally as 
well to suturalis. 
It is strange that in the references to the genus Ptero- 
stenus, Lac. (= Stenoderus, Latr.), no mention seems to 
have been made of a curious character presented by the 
head. This consists of a small, somewhat oblong, de- 
pression placed on each side just anterior to the cheek, 
and guarded in front by a flat blade-like process which 
extends along its middle and projects freely above. A 
similar depression and process are present on each side 
of the front of the head in the genus Syllitus. 
Stenoderus maculicornis, Saund., does not possess this 
character, and in other respects also differs from the 
remaining species of the genus. It would be better 
placed in Aphiorrhyncus.
