By Thomas G. Sloane. 



EURYSCAPHUS EBENINUS, n.Sp. 



Black, shining. Head subquaclrate (7 x 9 mm.) ; frontal sulci 

 parallel towards the front then curving sharply out towards 

 the base of the mandibles, a curved impression connecting them 

 behind ; the space between the sulci and antennae slightly rugu- 

 lose ; eyes not prominent, a short blunt process projecting 

 forward below each ; a single supra-orbital puncture on each side. 

 Prothorax transverse (8 x 13 mm.), not convex, widest behind the 

 middle ; sides slightly rounded, and a little narrowed to the 

 front ; anterior angles obtuse, strongly produced, posterior angles 

 rounded, not marked ; anterior margin sinuate ; base distinctly 

 lobate ; lateral border strongly reflexed, wider on each side 

 behind, narrow on the basal lobe ; median line distinct, 

 ending behind in a strong transverse impression defining the basal 

 part ; two marginal punctures on each side as usual in the genus. 

 Elytra subcircular (17 x 16 mm.), convex, smooth (some faint 

 traces of stride towards the apex), broadest before the middle, 

 rounded on the sides ; humeral angles rounded, with the margin 

 very strongly reflexed ; lateral margins broad, not reflexed behind 

 but strongly so in front ; a single puncture on the apical third of 

 each elytron. Anterior tibise with two strong teeth externally, 

 and above these three small projections. 



Length 34, breadth 16 mm. 



Hab. — Yilgarn, West Australia, 200 miles north-east of York, 

 W.A. 



I am indebted to Mr. C. French, Government Entomologist of 

 Victoria for my single specimen of this fine species.
