This species varies much in size and in colour, and in New Zealand 

 it frequently has a very dark hue. The specimen from the Sandwich Isles 

 is of small size and rather slender, and the prothorax is slightly more 

 elongated and angular than that of the typical form, but this difference is 

 hardly sufficient to consider it as another species.
