OF NEW ZEALAND. 643 



Rather narrower than T. a-fiea, and the elytra more cuneate. The 

 nearly aUied Australian genus Thallis, Er., has filiform palpi. I have 

 named this interesting species after Captain Broun, whose numerous 

 discoveries are adding so much to our knowledge of the insect fauna of 

 New Zealand.
