certain types which appear to appertain to local races; these 

 "local races" may pei'haps in reality be valid species. Living 

 specimens have the disc of the elytra suffused with metallic 

 colouring of a more or less brilliant green tint and present in a 

 high degree the pseudo-sulcate appearance referred to above in 

 the general remarks on this subgroup. Dried specimens are of 

 uniform brown or testaceous colour on the upper surface, except 

 some dark colouring present (at any rate on most specimens) on 

 the back of the head but only visible when the head is considerably 

 extruded, and some dark colouring always (as far as my obser- 

 vations go) on some at least of the ely tral series, which latter dark 

 colouring is in rare examples vaguely extended to the interstices. 

 The following notes indicate the special characteristics of some local 

 forms, as I believe them to be. 



The type (assuming Dr. Chapuis' identification to be correct, I 

 have an example named by that learned author) occurs in N.S. 

 Wales, but in my experience is rare. Its special characters con- 

 sist in the under surface, legs and antennte being entirely of 

 pale brown colour, the dark colouring of the elytral series limited 

 to the 1st and 10th series, the convexity of form in the ^ at its 

 maximum, and the closeness of puncturation on the prothorax and 

 in the elytral series at its minimum. 



Another race occurring in N.S. Wales has the under surface, 

 the femora and the outer joints of the antennse more or less black 

 or infuscate, other elytral series (besides the 1st and 10th) tend- 

 ing to be of dark colour, the form (especially of the male) tending 

 to be less convex than in the type, the puncturation of the pro. 

 thorax evidently closer than in the type and slightly asperate, 

 and the punctures of the elytral series (especially in the male) 

 somewhat more closely disposed. 



In Victoria (as far as I have observed only in the mountainous 

 regions) occurs a form coloured like the last mentioned except that 

 the dark colouring of the elytral series tends to be faintly suffused 

 over the interstices. In this race the convexity of form is at its 

 minimum (especially in the male) and the closeness and asperity 

 of the prothoracic puncturation is at its maximum.
