132 Notes on Australian Coleoptera. 
impressions between the eyes ; these impressions expand 
considerably at their anterior part; the protuberances below 
the eyes not very considerable ; the thorax transverse, mar- 
ginated laterally, with the anterior angles rounded ; the pos- 
terior part much narrower, with the sides rather sinuous, 
which gives it a cordiform appearance ; it has a longitudinal 
strie in the centre, a transverse impression forward, and — 
another backward ; on the latter are two longitudinal im- 
pressions ; elytra oval, oblong; the lateral margin forming 
a sort of carina at the humeral angles ; a line of impressed 
points follow the margin in almost all its length ; the surface 
presents very faint longitudinal lines, rather elevated ; in 
some specimens fine isolated straight brown hair are dis- 
persed on the posterior part of the elytra; the anterior legs 
are tridentated ; the first of the teeth only rudimentary ; the 
other tibize having long brown hair; the intermediate pair 
with two teeth on their external side; they appear long, 
thick, and very acute ; the largest of the inner ones long, 
slender, and curved. 
This insect inhabits Swan River. 
The following sorts are real Scaraphites :— 
Scaraphites Gigas: length 23’; entirely black and rather 
glossy ; labrum and anterior part of the head covered with 
short longitudinal rugosities; a transverse impression in front 
of the eyes, and two longitudinal ones between them ; a | 
strong protuberance on each side of the head below those 
organs ; thorax transverse, emarginated in front ; the lateral 
sides marginated, narrowing in their posterior part, and pre- 
senting a strong sinuosity behind the posterior angles ; 
anterior angles advanced and rounded; the surface is covered 
with faint lines, which are longitudinal towards the anterior 
margin, but transverse and sinuous behind; these markings are 
stronger on the sides than towards the centre ; on the middle 
of the thorax extends a rather deep longitudinal sulcate ; 
elytra oblong, rather narrower than the thorax ; their 
humeral angles rounded, their sides almost parallel; they 
have a broad and deep margin on their anterior part, but 
which is very faint towards the posterior part of the elytra, 
and is bordered interiorly by a row of impressed points ; 
the entire surface is covered with rugosities, and marked 
with several feeble longitudinal punctated striz ; the under 
side is glossy, but covered with fine impressions; the 
anterior tibie have three very strong teeth on their exterior 
side.
