memoir on Liparetriis neglected to verify this determination 
of Macleay, and, assuming that hasalis, Blanch.,' was rightly 
identified by Macleay, redescribed the true hamJh as Macleayi. 
The synonymy which I believe to be correct, then, stands 
thus : — 
L. xylvirola, Fab., Burm. ( iicc, Macl), fem. 
salehrosus, Macl., fem. 
bamlis, Blanch, f nee, Macl.), mas. 
Marleayi, Blackb., mas. 
I do not think that any one comparing Macleay's description 
of salebrosus with Burnieister's of sylvicola can doubt that 
they refer to the same insect, which is a remarkably isolated 
species, and very common in southern Australia. As to 
Macleay's "bffsalis, Blanch," it is an Aufoinolus, and is found 
in Victoria and Tasmania. Unfortunately, Blanchard's des- 
cription of basalis is an exceptionally meagre one, and it was 
perhajDS not unnatural that Macleay should have referred it 
to the insect he did if he had not the genuine basalis before 
him. In fact, it is chiefly a matter of colourng and sculpture 
(although the two inseets differ very widely in respect of im- 
portant characters that Blanchard does not refer to). Both 
occur in Tasmania commonly. Blanchard says of basalis, 
"elytris fusco-rubris, basi late nigris," which exactly fits the 
male of sylvicola, Burm. Macleay says of the species that 
he regards as basalis, "elytra brownish-red, the base black- 
ish," which aptly describes his basalis, but not the male of 
sylvidola, the former having a mere blackish infuscation across 
the base of the elytra, the other a wide basal fascia, well 
defined, and of deep black colour. As to sculpture, Blanchard 
says of basalis, "prothorace scabroso x x eiytris punctato- 
scabrosis x x pygidio scabroso," which very correctly indicates 
the vermiculate-rugulose sculpture of sylvicola (as character- 
ised by Burmeister, who calls it "rugoso-varioloso"), and of 
salebrosus, Macl., which its author describes as "coarsely vario- 
lose-punctate." No other Liparetrvs known to me in nature 
or description has any such sculpture. L. basalis, Macl. 
(nee, Blanch.), is quite differently sculptured. Macleay calls 
it ''rugosely punctate," a term which he applies (correctly 
enough) to the sculjoture of numerous other JAj)aretri, corres- 
ponding to the "rugoso-punctatus" which Blanchard applies 
to the sculpture of various Liparetri. 
As to the identity of L. sylvicola (Fab.), Burm., and 
basalis, Blanch. (Macleayi, Blackb.), as sexes of one species, I 
can state that T have taken them paired in Tasmania subse- 
quently to my describing Macleayi. 
It is, perhaps, best to add that nothing short of Bur- 
meister's strong implication that his description of sylvicola
