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 protliorax is sli;;htly more 

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

 hardly sufBcient to consider it as another species.
