COLEOPTERA 369 



This fine Insect is apparently not very rare near Honolulu, but scarcely increases 

 its range.

So far as we know, there is no Ischiodontiis in the Sandwich Islands. From infor- 

 mation received from Mr Gahan of the British Museum of Natural History, it appears 

 certain that the insects in the Fry Collection, which Candeze described as /. haivaii' 

 ensis, were wrongly labelled as coming from the Sandwich Islands, the real locality 

 being the Samoa Islands.]

This species has recently been introduced into the Hawaiian Islands. I have only 

 one individual before me, and it differs a little from the New Zealand type in sculpture, 

 and in the form of the sides of the thorax and of the apices of the elytra, but these 

 differences scarcely go beyond the limits of variation. M. exsnl is also. I believe, an 

 introduction in the fauna of New Zealand, its native country being perhaps Australia.
