lescent ; epistenica quadrate, punctulate. Ventral segments : 

 three basal punctate (2nd and 3rd closely and finely), punctura- 

 tion obsolescent on three apical segments. 



9. Differing b}^ elytral interstices more depressed and opaque. 

 Length ll-b-l2-'d, breadth 4-44-6 mm. 



Ilab. — Neighbourhood of Sydney (Como; Froggatt). 



Very closely allied to S. monarensis, SL, but I think entitled 

 to rank as a distinct species; the differences from ^S'. ynoiiarensis 

 that I note are the elytra bluish, more convex in ^, more rounded 

 on sides; the interstices in ^ less convex, especially on apical 

 declivity; tarsi with onychium spinulose beneath. From *S'. civilis, 

 Germ., it differs by colour; smaller size; eyes more prominent; 

 elytra with interstices less convex near apex; metasternal episterna 

 shorter; three apical ventral segments without perceptible punc- 

 turation. 



Genus Pseudocexeus. 



Tschitscherine, Hor. Soc. Ent. Ross., xxv, 1891 : Leptopodtis, 

 Chaudoir and others. 



When M. Tschitscherine founded the genus Pseudoceneus, he 

 did not diagnose it, but merely indicated its position in his table 

 of Oceanic genera. According to his table the following will be 

 the characters assigned to Pseudoceneus : — 



Tooth of mentum emarginate; palpi more or less cylindrical; 

 pro thorax with one rather weak impression on each side of base; 

 elj'tra margined at base, 3rd inte^rstice 3-punctate; prosternal 

 episterna l?evigate; ventral segments not transversely sulcate. I 

 would add— winged; elytra with a striole at base of 1st interstice? 

 two anterior punctures of 3rd interstice near 3rd stria, posterior 

 puncture near 2nd stria. 



M. Tschitscherine says the type of Pseudoceneus is Argutor 

 holomelanus, Germ.; but with this I cannot agree. It seems that 

 European coleopterists have ascribed the name Argutor holonie- 

 lanus to some species other than that which Germar described 

 under this name; for Chaudoir referred A. holomelanus to his 

 genus Leptopodus, to which he also r-eferred Feronia (Poecilus)
