272 EEVISION OF THE GENUS ^^OTOXOML^S, 



like iV. variicollis, Chaud., and N. excisipennis, SI. ; from iV. 

 variicollis it is at once distinguished by the basal angles of the 

 prothorax not marked, and the posterior marginal puncture not 

 placed at the basal angle. N. excisipennis is thoroughly differen- 

 tiated from F. arthuri by its unusually narrow ninth elytral 

 interstice. 



NOTONOMUS MUELLERI, n.sp. 



Oval, robust. Head large ; prothorax subquadrate, lightly 

 narrowed to base; basal angles marked; posterior marginal punc- 

 ture at extremity of lateral channel just before basal angle; 

 elytra striate; interstices depressed, third 3-punctate on apical 

 two-thirds; humeral angles rounded. Black, nitid; legs piceous- 

 red. 



Head large [4 mm. {^) to 4*3 mm. (9) across eyes], convex; 

 frontal impressions weak; eyes with orbits reniform, convex, 

 much more prominent in $ than in 9. Prothorax broader than 

 long (4'5 X 5-6 mm.), depressed towards base, very little narrower 

 at base (4 mm.) than at apex (4-2 mm.); sides lightly rounded, 

 obliquel}' (not roundly) narrowed to base without sinuosity; base 

 widely truncate; basal angles well marked, obtuse; bordernarrow, 

 terminating at basal angles ; median line light ; lateral basal 

 impressions wide, shallow, straight and parallel at bottom. 

 Elytra truncate-oval (11-5 x 6*7 mm.), depressed; base wide; lateral 

 apical sinuosities well developed, wide ; basal border joining 

 lateral border without any interruption; tenth interstice feebly 

 developed. Intercoxal declivity of prosternum rounded; of meso- 

 sternum lightly concave; metasternum not channelled to apex. 

 Length 17-21, breadth 6-7-8 mm. 



Hah. — N.S. W. : Mount Kosciusko (specimens from Mr. W. W. 

 Froggatt). 



A distinct species; in facies it resembles N. i^eroni, Casteln., 

 but differs by colour, prothorax not sinuate on sides near base 

 and with basal angles obtuse; ^ with three basal joints of anterior 

 tarsi broadly dilatate and squamulose beneath, tfec. Its affinity 

 seems towards N. gippsiensis, Casteln.
