pressions wide, parallel ; a marginal channel extending from 

 posterior extremity of basal impressions and curving round the 

 basal angles at a little distance from the border. Elytra truncate- 

 oval (lO'O X 6'6 mm.), widest behind middle, a little narrowed to 

 base, feebly striate; striae obsolete towards sides (excepting eighth 

 and ninth;; third interstice 2-punctate on posterior half, ninth 

 seriate-punctate; basal border lightly arcuate on posterior margin, 

 not dentate at humeral angles; lateral border reflexed, lightly 

 carinate near base. Intercoxal declivity of presternum rounded; 

 of mesosternum concave. Length 17-21, breadth 5-7-7 "5 mm.

Chaudoir is the authorit}^ for placing Feronia hipunctata^ 

 Casteln., under N. ehalybeus, Dej., as a synonym, but I have never 

 seen any specimen so small as 13 mm., which Chaudoir gives as 

 the size of Dejean's type specimen. Judging from Newman's 

 description, I consider Feronia biptmctata, Casteln., to be con- 

 specific with Feronia philipjn, Newm. 



Var. (?) otwaijensis. Specimens from the Otway Forest have 

 the elytra a beautiful golden green, and the stride quite obsolete 

 on the disc. It seems a variety that requires a name. 



Hab. — Depths of the Otway Forest, between Cape Otway and 

 the mouth of the Gellibrand River (Sloane).
