the species of which (not greatly differing in size) it differs by 
its being devoid of iridescence, and having its pronofum sub- 
opaque and closely rugulose. 
L. Kreuslerce, Macl. Tne pronotuni of this species is 
stated by its author to be "free from hair except on the ateral 
margins." That, however, is a mistake. There are specimens 
in the Macleay Museum (bearing the name), no doubt in- 
cluding the type, and agreeing with the description in all 
other respects, but having the apical margin (as well as the 
lateral margins) of the pronotuni pilose. I have, therefore, 
no hesitation in correcting Sir W. Macleay's description ?u 
that respect. 
L. angulatus, Macl. Two specimens (male and femah'^ 
are pinntd into the label bearing this name in the Macleay 
Museum, and are doubtless the types. The species is one I 
have not seen elsewhere. It is near my L. fimhriatus, but 
differs from it mter alia by its strongly pruinose and iridescenf- 
elytra. 
FOURTH GROUP (a, B, C, DDD, OF TABULATION). 
This group is a somewhat heterogeneous assemblage of 
species, among which there is considerable variety of facies, 
etc. The characters that I have indicated as common to the 
group are well marked in all its species, with the exception 
that a few of them (notably the female of L. aridus, Blackb.), 
are somewhat intermediate between the fourth and seventh 
groups, owing to the basal joint of the hind tarsi being only 
a little shorter than the second joint. The use of this char- 
acter in the hind tarsi is too valuable in dealing with a long 
series of species to be discarded on account of these doubtful 
cases, but it seems necessary to furnish a note on each of the 
latter showing how the species differs (disregarding the hind 
tarsi) from its allies in the seventh group. 
L. aridus, Blackb. The entirely testaceous colour of this 
species prevents its confusion with any member of the seventh 
group except disfincfiis, Blackb. The basal joint of the hind 
tarsi in the latter is quite fully as long as the second joint, 
the general build is much more robust than in aridus^ the 
prothorax much more narrowed in front and much less finely 
punctulate on its upper surface, its colour a much less pallid 
testaceous, etc. ; also it has remarkable sexual characters on 
the abdomen which are wanting in aridiis. 
L. picipennis, Germ., can scarcely be confused with the 
seventh group, as the basal joint of its hinder tarsi is quite 
distinctly (though not very much) shorter than the second 
joint. It presents the unusual character of a row of erect 
hairs widely interrupted in the middle on the front margin
