female). They difter in Iiaving tlie yellow colouring less vivid 

 and confined to the mouth organs, legs (even these iDeing in some 

 examples clouded with brown), and (in occasional examples) the 

 extremities of the anterior margin of the prothorax. The anterior 

 prolongation of tlie metasternum appears to be a little wider than 

 in the type, and on this account there is a possibility of their 

 being a distinct species. 



The following forms appear to me to be merely varieties or 

 local races of S. fiavifrons : —

 Apparently not a variable insect ; rather narrow and parallel.. 

 The puncturation of the upper surface smoother finer and less 

 close, that of the underside very much more sparing, than in 

 ;S'. ^fiavifrons ; the middle of the metasternum without visible 

 punctures. The elytra has a mottled (yellow and reddish) appear- 

 ance difficult to describe in detail, but in all the examples I have 

 seen there is on each elytron a golden yellow vitta (very con- 

 spicuous in certain lights), which runs from immediately below 

 the shoulder obliquely to just in front of the middle of the suture, 

 which, however, it does not quite touch — the vitta? of the two 

 elytra thus forming a V (the two arms, however, not quite 

 meeting at the angle). On each elytron the darkest colouring 

 (in some examples deep pitchy) forms a margin on both sides of 

 the vitta. The suture between the first and second ventral seg- 

 ments is tine but distinct. 



AVidely distributed in South Australia, but apparently not 

 very common. I have it from Kapunda, Petersburg, and Lake 

 Torrens.
