margin. Beyond this there is a disconnected spot with an 

 angular frontal projection. 



On the female the prothoracic markings are generally- 

 smaller than on the male. On the elytra they are sometimes 

 similar, but the oblique vitta on each elytron is frequently 

 broken up into two spots, of which the postmedian one appears 

 (with its fellow on the other elytron) as a more or less zig-zag 

 fascia, but sometimes the apical portion appears as a small 

 disconnected spot of irregular shape. The markings on the 

 pygidium also vary considerably in size.

PI. x.. fig. 69; pi. xiii., fig. 186. 



All the specimens that I have seen of this species have 



two black spots on the prothorax and three on each elytron; 



as on the type. The spots are always in the same positions 



and vary but slightly in size.

 PI. ix., figs. 65 to 68. 



On this species there is a more or less M-shaped blotch 

 on the prothorax, that is but seldom broken up into spots. 

 On each elytron there are usually four spots : one on shoulder,, 

 one touching the hind margin of the scutellum, one (usually 

 transverse) just beyond the middle, and the fourth close to 

 apex. The' third spot is sometimes joined to the suture, but 

 is usually free. On a specimen in the National Museum, 

 Melbourne (fig. 65), it is joined to the second spot. One small 

 male (fig. 68) is without the humeral spot. 



Three of the specimens before me have the derm shining ; 

 but this was probably caused by improper treatment.

d ■ Flavous ; head (except for a subtriangular space in 

 front of the clypeus), a large irregular somewhat M-shaped 

 blotch on prothorax (connected in two places with the base), 

 margins of scutellum, suture, sides, and some markings on 

 elytra, base, apex, and some spots on pygidium and under- 

 surface (except some spots at the sides and the mesosternal 

 process) black. 



Head with rather small, irregularly-distributed punc- 

 tures. Clypeus ridged towards each side, but the sides them- 

 selves rounded, apex moderately notched ; punctures more 

 distinct than on head ; club about as long as the space be- 

 tween eyes. Prothorax with sides rather strongly diminishing 

 in width from base, hind angles strongly rounded ; medio-basal
