or A-USTEALIAN PHYTOPHAGOUS BEETLES. 477 



rugulose and finely punctured. Tibiae stout, increasing in thickness 

 from base to apex, their outer surfaces broadly grooved, margins 

 of the groove in the four hinder tibise each armed just before the 

 apex vp^ith an acute tooth ; outer border of the groove on the 

 front pair armed witb a similar tootb ; hinder tibia equal in 

 length to the femur. 



Genua Aesipoda, JSrichs. 



Aesipoda piceipbs. Elongato-ovata, convexa, cuprea, nitida, 

 pedibus piceis ; antennis corporis dimidio vix brevioribus, ad 

 apicem incrassatis, nigris, basi piceis ; thorace crebre punctato, 

 basi utrinque sulco brevi perpendiculari im presso ; ely tris tenuiter 

 punctato-striatis, interspatiis plauis, tenuissime punctatis. Long. 

 2lin. 



Sab. Western Australia {JDuboulay). 



Head trigonate, rugose ; carina slightly raised, ill-defined, 

 acuminate at base and apex ; encarpse ill-defined, transverse, not 

 contiguous ; front impressed on either side Mdth a deep groove, 

 wbicli runs obliquely upwards along the inner border of the eye ; 

 antennae nearly half the length of the body, six outer joints 

 thickened and forming an indistinct elongated club ; six lower 

 joints piceous, the rest black. Thorax rather more than 

 twice as broad as long at the base ; sides straight and parallel 

 behind the middle, thence rounded and converging to the 

 apex, anterior angles oblique, thickened, obtuse ; basal margin 

 faintly sinuate on either side the median lobe, the latter scarcely 

 produced, broadly truncate ; upper surface rather strongly and 

 somewhat closely punctured ; base impressed on either side, at 

 some distance from the lateral margin, with a deep, slightly 

 curved, perpendicular groove ; in the middle between these grooves 

 is a faint indication of a transverse groove. Scutellum trigonate. 

 Elytra rather broader than the thorax, ovate, attenuated towards 

 the apex, convex, finely punctate- striate, the punctures rather 

 stronger on the basal half of the surface ; interspaces plane, 

 minutely but not closely punctured. Legs piceous ; hinder thighs 

 moderately curved, lower half of upper surface only slightly 

 grooved. 



Yery similar in form to A. consuta, Germ. : more robust and 

 less elongate than that insect, the antennae shorter and nnich 

 more incrassated towards their apices.
