puncturatiou resembles tliat o£ M. rotiondicollis, tlie punctures 

 in some specimens being like rather line transverse scratches 

 ^nd in others considerably coarser and not distinctly trans- 

 verse. 



I have taken an example o£ this species near Port Lincoln, 

 and there are two specimens in the South. Australian Museum, 

 of which the particulars o£ capture are not known. 



M. intricata, sp. nov. Oblongo-ovalis ; viridis aureo-micans, 

 prothorace elytrisque purpureo-notatis, anteunis tarsisque

"With a long series of specimens before me of this insect I 

 find mucli variety in respect of colour and size, but little in any 

 otber respect except that in some examples the thorax appears 

 -to be somewhat more strongly rounded laterally than in others. 

 A description in English will be desirable of the markings, as 

 it is difficult to describe them accurately in Latin, and I do not 

 find the slightest essential variableness in their shape, although 

 there is mucb in their color and intensity. They are as fol- 

 lows ! — On either side of the central line of the thorax a wide 

 longitudinal vitta touching the base, but not quite touching 

 the anterior margin and extending laterally nearly half way 

 to the margin (in specimens where the thorax is bluish this is 

 ■often very obscure, the ground colour being nearly the same as 

 that of the vitta) ; on the elytra an oblique vitta commencing 

 on the shoulder just within the base and running in the direc- 

 tion of the apex of the suture for about one-third the length 

 of the elytron where it becomes wider and turns transversely 

 towards the suture which it touches ; between it and the suture 

 there is another wider straight vitta which starts from the 

 base and joins the other vitta in its transverse portion ; the
