78 O E D E R—C O L E O P T E R A . S ECTION—P ENTAMERA,
Two other Australian species of this suh-genus, AHhroptenis MacLeaijii Donov., and Artkropiens Hopii
Westw., are figured in my Arcana Entomologiea, vol. ii. pi. L, figs. 4 and 5.
Five other species of the suh-genus, from Gayndah, Australia, are described by William MacLcay, Esq.,
in the Transactions of the Entomological Society of New South Wales, vol. ii. part ii, 1871, the characters of
which are subjoined, in order to make the present article complete up to the present time. Without actual
comparison with typical specimens, I am afraid to pronounce on the possible identity of some of them with some
of the species above described.
A E T HK O P T E E U S WESTWOODI I .
' Piccous brown, subnitid, and finely punctured. Antenna; short, with the first joint transverse, obtusely
angled, and trimcate; the second to the ninth inclusive more than four times broader than the length, and the
tenth more than twice the length of the preceding. Head slightly concave between the eyes, truncate behind,
and attached to the thorax by a thick neck, with the posterior angles prominent, obtuse, and clothed with stifii'
hairs. Thorax scarcely longer than the breadth, rounded at the anterior angles, slightly narrow-ed behind,
truncate at the base, margined and ciliated on the sides, and broadly impressed on" the median hnc, more
especially towards the base. Elytra rounded at the apes, with a small sinuation at the external angle. ' Le g s
and under side of the body thinly punctured, anterior tibi® with the external apical angle subacute, and the
apes deeply emarginate. Intermediate and posterior tibia; with the external apical angle very broadly roimded
and ciliated, and with the apex emarginate.
'Length, 5 J lines.'
A E THROP T E R U S MAS T ERS I I .
' Piceous black, subnitid, and finely punctured. Antenna; with the first joint square, obtusely angled and
truncate, the second to the ninth inclusive three times broader than the length, and the last more than twice
the length of the others. Head slightly concave between the eyes, truncate behind, and attached to the thorax
by a thick neck with the posterior angles obtuse. Thorax much longer than the breadth, and very slightly
narrowed behind, with the median line deeply impressed in the mi idle, but not extending to the apical and
basal margins, and with an indistinct fovea near the basal part of the lateral margin. Elytra tiimcate at the
apes, and slightly notched at the external angles. Legs and under side of the body closely punctured. The
tour anterior tibia; have the external apical angle acute and the apes deeply emarginate; the posterior are rather
more obtusely angled.
' Length, 6 i Hnes.'
A E T HR O P T E R U S ANGTJ STICORNI S .
' Of a piceous brown colour and nitid. Antenna; narrow; the first joint square with the angles obtuse,
the second to the ninth inclusive twice as broad as the length, the last equal in length to the two preceding
united. Head depressed ou the vertes and coarsely punctured, with a prominent cihated tubercle at the
posterior angles, and the base truncate. Thorax subcordiform, coarsely and transversely punctured, and with
the median line lightly impressed in the middle. Elytra thinly and finely punctured, and truncate at the apex,
with tw-o small notches at each external angle. Body beneath, and legs, thinly punctured. All the tibia; have
the external apical angle very acute.
'Length, 5} lines.
'This species seems to approach the A. pamllelocerus of Westwood.'
A E THEOP T E R U S KILIGI I .
' This species diff'ers from A. angustkonu in being of a pitchy red colour, in having no depression on the
top of the head, in the tubercle at the posterior angles of the head being much smaller, in the thorax being
more ciliated on the sides and having the median line more marked, in the external apical angles of the tibia;
being less acute, and in the narrower form of the whole body. The antenna; are of the same character as those
of^. anr/usiicornis.
'Length, 5 i lines.'

A R THE O P T E E U S E LONG A T U L U S .
' Long, narrow, of a reddish colour, subnitid, and punctate. Antennie rather short, the first joint nearly
square and \vith the angles obtuse, the second to the ninth inclusive three times broader than the length, and
the last more than twice the length of the preceding one. Head not depressed in front, and with the posterior
angles rounded. Thorax much longer than the width, very little narrowed behind, and not rounded on the
sides, with the mechan line obsoletely carinated, and broadly depressed near- the base. Elytra a little wider
than the thorax, and with the apex tri-emarginate in nearly equal lengths, and produced into acute points
between the emarginations. Apex of the abdomen nearly black. The external apical angle of the fore tibia; is
acute, that of the intermediate and posterior tibia; is rather obtuse with the apex subtruneate.
'Length, 4 lines.'
I have obtained a specimen of this distinct species during the progress of this sheet through the press.

OBS.—On a careful comparison I can detect no other characters to separate the somewhat larger Port
Natal specimens from the tyqjical specimen of F. Faussoieks, formerly in my Collection, and now in the Hopeian
Museum.
Prom the observations also of Herr Dohrn (Proc. Ent. Soc. Lond. Sept. 1, 1851), it is evident that the
Pentaplatarth-us Naialeusis of the Beriin Musemn, and F. iF-maculaius Buquet MS , are mere varieties of Fent.
Faximides Westw., more or less distinctly banded with black on the elytra.
