TWELFTH GROUP (a, BB, C, DD, OF TABULATION). 
Resembles the preceding group in respect of most of its 
characters, but has elytra glabrous, or with only a little pilo- 
sity near base. The following notes relate to members of this 
group. 
L. discoidalis, Macl. This and the next two species are 
very distinct, inter se, but with few distinctive characters 
that lend themselves readily to tabulation. Discoirlalis is re- 
presented in the Macleay Museum by two specimens (one of 
them presumably the type). Their elytra are remarkably 
coloured, there being only a very narrow black border, except 
at the apex, which is very widely of a deep black colour, so 
that to a casual glance they seem to have bright red el3^tra with 
a wide, apical black fascia. In one specimen the pronotum is 
p9,rtially red. The front tibige are distinctl}^ bidentate ex- 
ternally. 
L. occidentalis, Macl. Two specimens are pinned into 
the label bearing this name in the Macleay Museum. There 
is, however, a difficulty in accepting either of them as the true 
type, for Macleay says that the hind tarsi were wanting in 
the specimen described, which is not the case with either of 
those in the Museum. Nevertheless, as they are distinct from 
any other species that I can find to have been described, and 
agree with the brief description, they may fairly be regarded 
as correctly named. They resemble discij^ennis, Guer., in 
colouration, but differ from it widely by, inter alia, glabrous 
elytra and basal two joints of hind tarsi subequal. It is near 
discoidalis, Macl., undoubtedly, but with very much darker 
vestiture, and moreover the colouring of the elytra in the two 
examples of discoidalis is so conspicuous and unusual that 
there can be little doubt of its being a specific character. I 
think one of the specimens of this insect (as also of di.^coidahs) 
is a male. The apical ventral segment in both is not much 
different from that of male discipennis. 
L. luridipennis. A specimen bears this name in the Aus- 
tralian Museum, and agrees well with the description except 
in the pilosity of the pronotum being somewhat darker than 
''fulvo-villose" would lead one to expect. Its facies is very 
different from that of the preceding two species, the size being 
notably larger and the form more robust. The head is more 
massive, with the clypeus wide and subsemicircular (not un- 
like that of mfpennis, Macl.) — not at all of the discipennis 
L. lanattcolhs, Macl. The presumable type of this species 
is in the Macleay Museum. It is identical with my L. Pal- 
m.erstoni. Both names were proposed in P.L.S., N.S.W., 
1888. Macleay 's name is a month later than mine.
