Hah. : Queensland (given to me by Mr. C. French as coming 

 from Budgery Mountain, S. Queensland). 



This handsome species is allied to H. superbuin, Casteln., which 

 it resembles in facies; but diifers from it by its larger size, the 

 bright metallic colour of head and prothorax, prothorax with 

 basal angles roundly obtuse, elytra with basal border dentate at 

 humeral angles, etc. 



Genus P T E R o s T I c n u s. 



PtEROSTICHUS PIIYLARCHUS, n.sp. 



(J. Upper surface jeneous, j^rothorax more nitid and metallic 

 than elytra; under surface, legs, labrum and mandibles shining 

 black. 



Robust, elongate-oval. Head convex; front wide, lightly and 

 shortly biimpressed, swollen behind and below eyes ; mentum 

 with sides of sinus pai'allel. Prothoi'ax truncate-cordate 

 (7 X 9 '2 mm.), lateral impressions of base strongly impressed, 

 elongate, wide. Elytra oval (19 x 12 mm.), convex; deeply sti'iate; 

 humeral angles rounded ; interstices convex, third with five 

 punctures along its course, fifth and seventh with three similar 

 punctures, ninth seriate-punctate. Anterior tarsi with three 

 basal joints dilatate and squamulose beneath. Length 34, breadth 

 12 mm. 



Hab.: N.8. Wales— Bellinger River (Mr. J. H. Maiden). 



Closely allied to Feronia regalis, Casteln., from which it differs 

 by colour, more robust shape, eyes moi-e prominent, elytra with 

 basal border joining lateral border at humeral angle with hardly 

 any projection, femora thick and more dilatate in middle. This 

 species and Feronia regalis cannot properly be placed in the sub- 

 genus A^otonomus on account of the shape of the sinus of the 

 mentum for one reason; their place is evidently between Homa- 

 losoma and Notonoraiis and there seems no reason to separate- 

 tbem from Pterostichus.
