with irregular, confused punctures of the same size as those in the 

 series. Sternum, especially the prosternum, very coarsely punc- 

 tate, abdomen less coarsely punctate. Front femora enlarged but 

 not dentate, tibiae widely dilated at the apical two-thirds. 



^. Without tlie (clypeal) tubercles, the frontal horns replaced 

 by two wide conical tubercles, the antennal club smaller, the tibia? 

 only slightly dilated at apex. 



Dimensions^ 16 x 5(vix) mm. 



i?ab.— Lynndoch, S.A. (Tepper) ; Young, N.S.W. (Sloane) : 

 Teralga, N.S.W, and South Australia (British Museum). 



Eight specimens (5 (J, 3 9) examined; three from the South 

 Australian Museum, two from the British Museum, three from the 

 Melbourne Museum, labelled from the above localities. It is easily 

 distinguished by its greater size, the form of the male horns, its 

 different elytral puncturation, and the curiously widened tibiae of 

 the male. Types in the South Australian Museum. 



TOXICUM QUINQUE-CORNUTUM, n.sp. 



Elongate, parallel, opaque-black above, nitid-black beneath; 

 antennae and tarsi piceous, the apical joints of the former red. 



Head densely and strongly punctate, clypeus three-horned, the 

 middle one largest and widely triangular, obliquely pointing up- 

 wards, its base occupying the whole front of clypeus, with two 

 shorter triangular elevations forming a dentate extension, forwards 

 and upwards, of the canthi; the frontal horns flattened, widest 

 when seen laterally, sharply curved inwards at base, twisted back- 

 wards at apex, with a very small tuft of yellow tomentum on the 

 outside of apex; club of antennae moderately wide and four-joint- 

 ed, joints 9 and 10 largest, and rounded. Prothorax 3 x 2-6 mm., 

 bisinuate at apex and feebly so at base, slightly widest at apex, 

 anterior angles rather squarely rounded and depressed, sides nearly 

 straight and slightly narrowed to base, posterior angles obtuse; 

 disc very finely and densely punctate, with a faint indication of a 

 smooth middle line. Scutellum triangular. Elytra wider than pro- 

 thorax at base, and twdce and one-half as long; striate-punctate, 

 the punctures in the striae regular; of the same size, but more dis- 

 tant than in T. hrevicorne Pasc. Underside sparsely punctate, the
