96 FAUNA HAWAIIENSIS 



This species exhibits a great deal of variation in the form and proportions of the 

 prothorax, epistome, mandibles, etc. and there may possibly be more than one form in 

 the islands. The material before me is not sufficient to decide as to this, owing to the 

 development of the individual being subject to much variation ; but the varieties appear 

 to be to some extent located in different islands.

This species is common in the larval state, in wet or dry, decayed wood, and is 

 also found in trees that are not entirely dead. The imago is rare, being nocturnal, 

 and only occasionally attracted by light.

Hab. Oahu ; Honolulu (Perkins). No doubt recently introduced. The species 

 is widely distributed outside the islands, and its occurrence in Honolulu has no special 

 interest.

This was no doubt introduced, and it is doubtful whether it has become naturalized 

 or has died out. It was not met with by Mr Perkins. The species is widely dis- 

 tributed, having been found in Siam, Fiji, and the Philippine Islands as well as in 

 Tahiti. Mr Gahan considers Gelonaetha Thorns, to be the same genus as Astrhmis 

 Sharp. I was formerly of the opinion that Stromatium hirtum was a different species, 

 but I now accept Mr Gahan's identification of the two.
