144 Notes on Australian Coleoptera. 
From the Darling River. Named in honour of the cele- 
brated Australian explorer. 
Scarites Bostocki: length 10’; elongated, subcylindrical, 
of a shiny black ; head rather corrugated in front, with two 
longitudinal grooves between the eyes; these grooves diverge 
in front towards the anterior angles of the head ; thorax 
transverse, marginated, rounded at the posterior angles, 
bilobed behind, with a longitudinal sulcate in the middle ; 
a transverse impression in front, and two very faint longitu- 
dinal ones behind ; elytra rather depressed, with very faint 
longitudinal lines on their surface, and two punctiform 
impressions behind, these are situated one behind the other ; 
anterior tibiz armed with three teeth, the upper of which 
is the smallest. 
Received from the Rev. Mr. Bostock. It comes from 
Nickol Bay, on the north-western coast of Australia. 
Scarites Ruficornis: length 104’; of a very brilliant 
black ; head with its front part and labrum dentated ; the 
longitudinal grooves are rather short, and as usual diverge 
in front towards the anterior angles of the head ; thorax 
broader than wide, with the posterior angles rounded ; it 
has a longitudinal sulcate in the middle and an impression 
at each angle, the anterior being transverse ; elytra rather 
short for the genus, smooth (with a strong magnifying 
power a few faint strize are seen, particularly on the posterior 
part), with two punctures on the posterior part of each 
elytra ; anterior tibiz tridentated, the upper tooth smaller 
than the others; antenne hirsute and of a brownish red ; 
tarsi of the same colour. 
This insect seems to have an extensive habitat. I have 
specimens from the Manning River, and Mr. Howitt found 
it near Cooper's Creek. In some immature specimens the 
legs are of a brownish red. 
Scariies Bypunctatus: length 9’; rather subcylindrical, of 
a glossy black ; head with longitudinal striole in front, and 
having between the eyes two strong longitudinal impres- 
sions, the breadth of which increases in front so as to give 
them a triangular form ; thorax rather transverse, with the 
sides almost parallel ; the posterior angles rounded ; on the 
centre is a longitudinal sulcate, in front a slight transverse 
impression, and on the posterior part two punctiform, 
rounded and deep impressions ; elytra rather long, parallel, 
verv feebly striato-punctated, with a transverse impression
