The specimen of this insect still preserved in the Banksian 

 collection, though in bad condition, is recognizable as a species

 example of the species, among the hundreds of specimens of

 remarkably elongate and parallel-sided, b\ lines long, with 

 the apices of the elytra produced and divaricate ; in colour it 

 resembles X. griseus.

The descriptions of Boisduval and Newman agree very well 

 with a common species, to which the ty^e of Fabricius belongs. 

 Mr. Lawson has sent it in great numbers from Auckland, and 

 I have also received it from Christchurch. It varies in size 

 from 3 to G lines ; and the apices of the elytra are singly
