shorter to place the species in my fourth group rather than 
the seventh. Apart from that character, its uniform pale 
colour (except on the head and sterna) distinguishes it readily 
from all the species placed in tlie seventh group. 
FIFTH GROUP (a, B, CC, D, OF TABULATION). 
This group differs from the second by the much greater 
length of the basal joint of the hind tarsi in comparison with 
the second joint. The following are notes on some of its 
species : — 
L. pruinosus , Burm. Macleay did not know this species. 
I have found in Mr. Griffith's collection two examples (from 
Tasmania, the original locality), which agree very well with 
Burmeister's description. There appears, on first thoughts, 
to be a serious discrepancy from Burmeister's description, 
which attributes to pruinosus hind tarsi having the basal 
joint longer than the second joint, whereas I have placed the 
insect in a group having those joints equal, or almost equal. 
The fact is, Burmeister did not separately describe the hind 
tarsi of each species, bu*^- made his primary division of the 
genus into species having Ca J the basal ; or fh J the second 
joint longer than the other, and recognised no intermediate 
group, and by placing prumosus in (a) he indicates the basal 
joint as tiie longer. If the basal joint of the species before 
me be examined (with care that the whole length of the joint 
be in sight) it is seen to be slightly longer than the second 
joint, so that in Burmeister's arrangement it would properly 
stand in (a), but the difference is so slight between the 
length of the joints that they must certainly be called sub- 
equal. In the Macleay Museum there is no Liparetrus 
ticketed "prutnosus," but two examples (from Tasmania), of 
the insect referred to above are ticketed "vestitus, Blanch.'^ 
I have no doubt of their being correctly named, and of resfi- 
tus and prtiinosiis being synonyms. In his monograph Mac- 
lea}'- places vest it us in his section with the "body squamose," 
but the specimens in the Macleay Museum (presumably those 
Macleay described) present no such character, nor does Blan- 
chard attribute squamosity to vestitus. Blanchard's figure 
in the "Voyage au Pole Sud," is evidently the figure of this 
insect, and the Jiahitat is given as "Tasmania," although in 
Blaiichard's "Cat. Coll. Ent." it is "Nouv. Roll." There are 
in my collection examples of a Li^Mretna^ from New South 
Wales that I cannot distinguish from the Tasmanian ex- 
amples of vestitvs except by their colouring, which is very 
variable. Unfortunately, all the Tasmanian specimens that 
I have seen are females, so I cannot be sure of their identity 
with those from New South Wales. In some females of the
