The black colour, slender legs, and peculiar form of the 

 thorax are quite sufficient characters to distinguish this little 

 species. 



This insect was sent from Auckland by Mr. Lawson ; and 

 I have recently received an individual taken at Tairua, and 

 with Xo. 40 attached, from Captaiu Broun.

 colour being all somewhat similar.
