Either this insect is one of a series of very closely allied species 

 (most of them as yet nndescribed) or it is extremely widely 

 distributed in S. Australia and variable to the last degree. I 

 believe the latter to be the case, as, with a considei-able series 

 before me, I find that although specimens may be selected which 

 on a casual glance it is scarcely possible to believe conspecific 

 with each other, yet no definite character appears to distinguish 

 them, and, moreover, they are connected by intermediate forms 

 in the most puzzling manner. 



The following characters are common to all the specimens I am 

 considering : — prothorax with the sides well rounded (that of the 

 male more elongate and with less strongly rounded sides than 

 that of the female), elytra clothed with rather long erect sette, 

 conjointly narrowly rounded at the apex, and having their shoul- 

 ders rounded. 



The size varies from long. '2^ to long. -4 lines, and it is ditiicult 

 to find two S})ecimens in which the scales form an identical pattern. 

 The most constant marking (which seldom varies much except by 

 abrasion) is a narrow tlexuous line of whitish scales on each side 

 of the prothorax. In one form the prevalent scales of the upper 

 surface are dark fuscous and the lighter scales are quite silvery- 

 white, forming (besides the prothoracic lines mentioned above) on 

 each elytron a narrow sutural vitta, a spot near the scutellum, 

 and a wide lateral vitta (suddenly dilated about the middle of its
