The specimen of this insect still preserved in the Banksian 

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

 of Xylotoles, and doubtless a male ; but I have seen no second 

 example of the species, among the hundreds of specimens of 

 Xylotoles sent home by Mr. Lawson from Auckland and a

 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 type of Fabricius belongs. 

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

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

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