descent; under surface piceous-brown; tibise, tarsi and antennae 

 ferruginous. 



Prothorax transverse (1-5x2 mm.), widest about middle, hardly 

 narrowed to base, gently but decidedly narrowed to apex; sides 

 lightly rounded; apex strongly emarginate; anterior angles promi- 

 nent, obtuse; base truncate-emarginate; basal angles obtuse; base 

 longitudinally impressed on each side of peduncle; external basal 

 impression wide, feebly marked. Elytra oval, hardly wider than 

 prothorax (3"5 x ■2'1 mm.), lightly convex; sides very lightly 

 rour.ded, hardly narrowed to shoulders; strise well marked; inter- 

 stices depressed on disc, those on sides convex towards apex, 

 second and fourth wide, third much narrower, hardly wider than 

 first; basal striole of second interstice not long; punctures of third 

 interstice strongly impressed; basal border arcuate on posterior 

 margin, with external angles lightly marked. 



Length 5-8-6-5, breadth 2-1-2-5 mm. 



Hab. — Bridgetown, Donnybrook (Lea). 



In facies almost exactly resembling the small specimens of S. 

 anstralis, Dej., from Swan River, but differing by the narrow 

 third interstice of the elytra with its subfoveiform punctures; the 

 fifth interstice, though wider on the disc than the third, becomes 

 equally narrow at the base ; it is a marked character of this 

 species that the third and fifth interstices are much narrower at 

 the base than the fourth and sixth.
