138 NOTES ON AUSTRALIAN COLEOPTERA, 



mitchelli Hope, *S. ocelligera C. & G., S. octospilota C. & G., «S'. 

 Thomsoui Saund. (with its var. dnlcis Blackb.), *S. virginea 

 Erichs., S. Wilsoni Saund. 



Four of the above, together with S. viridis (a Victorian variety 

 of S. cyanicollis Boisd., found also at King Island, Bass Strait) 

 are often so alike in size and colour (metallic green, rarely blue, 

 with or without yellow markings) that it may be useful to note 

 the distinguishing characters. 



S. virginea Erichs. — Each elytron with four carinate costav, 

 the yellow markings are a shoulder spot, two straggling, often 

 disjointed and thin fascise, the first median, the second ante- 

 apical, generally with one elongate spot between the first and 

 second cost;e opposite the shoulder spot, sometimes with an 

 irregular yellow line at apical sides. Pronotum irregularly, not 

 closely, punctate. Dimensions : 8- 1 3^ x 3-5£ mm. 



Hub. — Strahan, Waratah, West Coast. 



S. flavopicta Boisd. — The typical form has an oval shoulder 

 spot, a long, fiddle-shaped band from base to sides, and a latero- 

 apical band. The intervals are almost smooth, or very faintly 

 punctate: the pronotum is closely punctate. The prothorax is 

 very convex, with its sides widely and evenly rounded. Varieties 

 contain every possible variation of colour to be found by omitting 

 parts of the yellow markings, down to a concolorous metallic 

 green. Dimensions: 8-11x3-4 mm 



Ilab. — Hobart, Launceston, Strahan, &c. The commonest of 

 the Tasmanian species. 



S. ocelligera C. & G. — An elongate, orange shoulder spot, a 

 wide, subapical, orange fascia surrounding a green centre on each 

 elytron, intervals minutely punctate and wrinkled, pronotum 

 very closely punctate. Dimensions : 9-11 x 3^-4 mm. 



Hab. — Bellerive (Hobart). 



S. dimidiata Cart. —The typical form has a small shoulder 

 spot, a median fascia widely separated at the suture, a narrow, 

 arcuate, preapical fascia, joining a well-marked, latero-apical 

 band. The intervals closely and rather coarsely punctate, the 

 pronotum not closely punctate. 



Var. leai Cart., is without the median fascia. [N.B. — In the
