AUSTRALIAN SCARITIDA. 85 
the pronotum and elytra, the margins of which are more elevated with a bright golden green 
hue. The head has two deeply-impressed lines on the crown forked in front ; the right man- 
dible has two teeth in the middle, the lower one being very large, and composed of three united 
together ; the left mandible has two teeth within, between which is a very small one. The 
anteune are as long as the pronotum and half of the head, slender and not compressed, with 
the second joint a litle shorter than the third. The pronotum is very broad and short, 
with the sides straighter than in any of the preceding species, and more strongly margined, the 
hind margin almost forming a regular curve. The elytra are ovate, with the humeral angles 
rounded, but with a small elevated obtuse tooth-like angle; within the lateral margin is a 
series of punctures. The legs are black, the anterior tibie with three teeth on the ontside.

The above additions to the original Fabrician description (which is inclosed in inverted 
commas) are supplied, together with the accompanying figure, from the original unique specimen 
still in the possession of the Linnawan Society. The species described by Bonelli, and sup- 
posed by him to be identical with the present species, being quite distinct, I have applied to 
it the name of C. Bonellii; and in order to avoid any further confusion between the two 
species which have received the same specific name, I have also designated the present species 
with the name of its original describer. 
Species VII.—Carenum Spencii (Pl. 21, fig. 6, C.) Nigrum, subopacum, tibiis anticis 
extus tridentatis, elytris excavationibus numerosis rotundatis, triplice serie in singulo 
elytro ordinatis, spatiis intermediis clevatis. Long. corp. lin. 9. Mus, Melly. cum 
hoc nomine inscriptum. Inhabits New Holland. 
Syn.—Carenum Spencii, Westw. in Taylor’s Annals of Nat. Hist. Oct. 1841, p. 123. 
The head in this very distinct species has two impressed lines on the crown, the pronotum 
has the posterior angles rather strongly emarginate, the dise with a deep impressed line, and 
near the fore margin is a row of fine longitudinal strige. The elytra have an indistinct row 
of punctures on each side of the suture, succeeded by three rows of large deeply excavated 
round but irregular impressions, the space between the rows being elevated; the sides are 
margined, and within the margin is a row of deep small punctures. The fore tibie are very 
strongly palmate, having three teeth on the outside. 
Srecrrs VIII.— Carenum gemmatum, Hope, MSS. (Plate 21, fig. 7,7 a, 7 b, and 7 c.) 
C. viride, elytris cupreo-tinctis, punctis magnis distantibus triplice serie in singulo elytro 
ordinatis, tibiis anticis dentibus duobus magnis alteroque minuto externis. Long. corp, 
lin. 43; lat. elyir. lin. 13. Mus. Hope. Inhabits Port Essington. 
This beautiful little insect is most nearly allied to C. Spencii, but is, however, quite dis- 
tinct. The head is black in front but green behind; it has two deep impressed lines 
diverging behind, united with a slightly-waved impressed line which runs across the head 
behind the eyes; behind the labrum the two lines are strongly angulated with a small 
puncture near the angle; the labrum is horizontal, with the middle emargination rather deep 
(7 a, front of head; 7 b, maxilla; 7 c, labium). ‘he right mandible has three nearly equal 
teeth in the middle; the left one has also three, but the middle one is very small. The 
antenne are very short, with the terminal joints broad and compressed; the second and third 
joints are very nearly equal in length. The thorax has the Jateral margins not much rounded, 
and the hind margin nearly forms a regular curve; the dise has a central impressed line, and 
there is an oblique impression near the posterior angles ; the elytra are more oblong thau in 
the preceding species; the suture is deeply impressed, and each elytron bas three rows of 
deep round impressions placed at unequal distances apart; the two rows next the suture 
having four, and the one next the sides only two impressions : the fore tibiw have tivo large 
and one very minute teeth on the outside.
