266 EEVISION OF THE GENUS NOTONOMUS, 



description is applicable to it, while it does not at all suit the 

 species {N. angustihasis, SI.) to which Chaudoir has applied it. 

 The habitat given by Motschulsky lends support to this view, 

 viz., neighbourhood of Port Phillip, which is the habitat of N. 

 accedens, but not of N. anyicstibasis. 



^OTONOMUS POLiTULUS, Chaudoir.

9. Oval, depressed. Black, shining. Head moderate (3-1 mm. 

 across eyes), smooth, convex; eyes prominent, almost hemispheri- 

 cal. Prothorax broader than long (3-8 x 4*7 mm.), wider across 

 base (3-7 mm.) than apex (3-3 mm.), widest about middle, sub- 

 depressed, lightly declivous to sides, depressed towards middle of 

 base; sides lightly rounded; apex lightly emarginate; anterior 

 angles obtuse, not close to head ; base widely emarginate in 

 middle; basal angles obtuse; posterior marginal puncture a little 

 before basal angles on the explanate margin, not on border; 

 median line lightly impressed; lateral basal impressions rather 

 wide, long, shallow, lateral basal spaces slightly convex. Elytra 

 ovate (10-3 X 6 3 mm.), subdepressed ; lateral apical sinuosities 

 almost obsolete; humeral angles rounded; basal border joining- 

 lateral border without interruption ; striae strongly impressed, 

 seventh light, ninth distinct; interstices depressed, not convex on 

 apical declivity, third 2-punctate (sometimes 3-punctate), tenth 

 moderately developed towards apex. Intercoxal declivity of 

 prosternum rounded; of mesosternum concave. Length 17, 

 breadth 6*3 mm. 



Hah. — Tasmania. 



Though N. politulus seems to have the third interstice of the 

 elytra more often with two than with three punctures, I have 

 thought it more allied to y. kosciusklanus, SI., and kindred 

 species than to N". king I, Chaud., and other typical species of the 

 group characterised by their bipunctate third elytral interstice.
