hrunneus anrl ohldiujus^ inttr uiiu, by its head not being 
granulate. It is also quite distinct from all the other AnUo- 
chri known to nie by the extraordinary thickening of the 
hinder part of the lateral margin of its elytra. Among the 
remaining eleven specimens before me there are clearly at 
least four species, but as 1 am unable to point out any defi- 
nite character in them as reliably specific — as one of them is 
certainly variable in respect of sculpture — and as any one of 
them might be .1. aherr(nii<, Fairm., I must leave the determi- 
nation of the species of this genus for future study and in- 
creased material. 
LAMELLICORNES PLEUROSTICTI. 
The Tro<jidt6, which end, as far as known Australian 
species are concerned, with Antiochrus (vide sypru), form, in 
the Lacordairean system of classification, the sixth tribe of 
the first subfamily, or "legion," ( Lamellicor)ie.< luparosficti) 
of the family Laniellicornes. The seventh tribe of that sub- 
family, the GUi'phyrides, has no known representative in Aus- 
tralia. One Australian genus (PlKfMoynatJia), through its 
alliance with a non- Australian genus ( Ado pus), which Erich- 
son referred to the Ghiphyj-ules, has been placed by some 
authors in the same tribe ; but Lacordaire (Gen. Col., iii. ; p 
160 ; note 4) has shown that Erichson was wrong in referring 
Aclopus as he did, and that the proper place for it is in the 
second subfamily of LanieUicornes. That this is the case with 
Ph(enognat]ia is obvious to any one who examines a specimen 
of that genus. These remarks seem desirable because Phce- 
no(/natha stands in Masters' catalogue as a Glapliynd. 
The LaiveJ] irornes j)Ie/(rosficfi are distinguished from 
the first subfamily by the position of their abdominal stig- 
mata, the hinder three of them being placed (not on the con- 
nective membrane of the dorsal and ventral surfaces, but) on 
the ventral surface of its segment, so that the last of them is 
ordinarily visible when the elytra are closed, as well as when 
they are set open to expose the abdomen fully. 
These two subfamilies (or 'legions," a.3 Lacordaire calls 
them) comprise on the Lacordairean system of classification 
the whole of the LameUicornes. The second subfamily, with 
which I liope to deal, in respect of its Australian species, in 
this and some following memoirs, is divided into four '"tribes," 
eacli of which is extensively subdivided into grouj^s, sub- 
groups, sub-sub-gioups, and so on. The four main groups 
or "tribes" are the Melolont hides, Rutelides, Dynastides, 
and Cetoniides. The first of these differs from the others in the 
hinder three of the abdominal stigmata being only slightly 
distant from the connective membrane, with the consequence
