Scarites Substriatus : length 11’; elongated, of a shiny 
black; head having between the eyes two longitudinal 
grooves, which unite together in front; thorax almost square, 
rather transverse ; the posterior angles are rounded ; there 
is a longitudinal sulcaté in the middle, a faint transverse 
impression in front, this is only well marked at its exte- 
mities, and two deep punctiform impressions on its posterior 
part, one behind each angle ; on its surface are seen very 
faint transverse striole; elytra rather depressed, with longi- 
tudinal ridges but no distinct strie ; on the posterior part 
of each striz are two punctiform impressions, situated one 
behind the other ; front tibize armed with three teeth, the 
first much smaller than the others. 
From the Darling River. 
Note.—This sort can only be taken for Subporcatus of 
Macleay, jun., but is very distinct by the markings of the 
head. 
Scarites Plicatulus: length 12’; of a brilliant black ; 
forehead with four longitudinal grooves between the eyes, 
the external extending to the back part of the head by a 
sinuous line, in frontvthey diverge towards the anterior 
angles of the head ; on the space extending between the 
grooves and the base of the mandibule is a series of longi- 
tudinal and deep striatule ; thorax almost square a little 
transverse, rounded behind, marginated all round, having 
a deep longitudinal sulcate in the middle and an impression 
at each angle; these at the anterior angles being oblique and 
at the posterior longitudinal ; elytra not very convex, almost 
smooth, with very faint longitudinal ridges, and two puncti- 
form impressions on the posterior part, one behind the other; 
eles legs tridentated, the upper tooth smaller than the 
others. 
This insect comes from Escape Cliff, in the Northern 
territory, and was given to me by Dr. Mueller.
