AUSTRALIAN SCARITIDA. 87 
margins being margined, with two or three setigerous punctures wide apart within the margin. 
The disc of the pronotum is marked by a slender impressed line. The meso-thoracic 
peduncle is slender and narrowed behind; the elytra are as broad as the widest part of the 
head; they are smooth and shiny, with the suture slightly impressed, the anterior and 
posterior angles being equally and gradually rounded off; each elytron is marked with a deep 
puncture near the tip, and is margined with a beautiful blue tinge ; the margin itself is raised, 
and within it is a series of small setigerous punctures. The legs are short, and the auterior 
tibia have two very strong teeth on the outside.

This fine species entirely recedes from the ordinary form of the genus in its broad outline 
and circular elytra. It is black and shining. The head is broad, and produced into an angle 
outside the eyes. It has a round impression on the crown, with an oval fovea on each side 
extending nearly to the base of the mandibles, terminating ina pointon the crown. There are 
also two smaller impressions in the front of the clypeus; the right mandible is 3-dentate, 
the inner tooth almost obliterated; the left mandible is 4-dentate, the inner tooth large ; the 
pronotum is broad, and margined with a rather deep central longitudinal sulcus, terminating 
in a cordate impression, and with an oblique impression at each hinder angle. The elytra are 
circular subconvex, with the suture impressed ; each is marked with six almost obsolete simple 
strie ; within the raised lateral margins is a numerous series of small punctures, and at a small 
distance from the sides, another row of six punctures placed wide apart ; and there are three 
other punctures forming an oblique line towards the extremity of the suture. The anterior 
tibie are externally 3-dentate, and the middle tibiw are furnished on the outside near the tip 
with a strong sharp slightly-curved spur, above which the limb is finely serrated on the 
outside.

This species is much smaller and narrower than the preceding ; the head is angulated outside 
the eyes, between which are two oval impressed fovex, which, as well as the front of the head, 
are strongly crenulated. The right mandible has two compound teeth, the front one formed of 
two projections, and the hind one of three, of which the middle one is very small. The left 
mandible has three teeth, the middle one small, and has a small projection in front of the large 
anterior tooth. The pronotum has a longitudinal sulcus transversely crenulated, and has a 
small impression on each side towards the anterior angles, and an oblique fovea at each of the 
hinder ones. The elytra are obovate, each having seven slightly punctated striw; there is 
also a numerous series of punctures within the lateral margin, at a short distance from which 
is another row of six punctures at unequal distances apart, and with three other punctures form- 
ing a nearly straight line towards the extremity of the suture on each side. The anterior tibiz 
are tridentate, and the middle tibize are armed near the tip on the outside with a thick curved 
spur obliquely truncate at the tip.

This species is closely allied to the last, but differs from it in the strong but acute tooth on 
the outside of the middle tibise, and in the want of crenulations on the forehead, pronotum, 
the punctures of the elytra, &c. It is black and shining, the head not angulated beyond the 
outline of the eyes. The crown of thé head in front has two deep oblique oval impressions 
extending nearly to the base of the mandibles, and two punctures close to the fore margin 
of the clypeus, and one on each side near the hind angles of the eyes. The pronotum has a 
central sulcus terminating at a short distance in front of the hind margin, and the hind anzles 
are scarcely foveated. The elytra are broad and obovate, with the rudiments of three or four 
very slight striz on each, which are lost ata distance from the apex of the elytra. Close to
