 Hab. All the islands (Blackburn, Perkins).

Mr Perkins' collection contains two specimens of a Psamniodiiis, one smaller and 

 lighter coloured than the other. To what species they belong is not certain, but 

 comparison with a number of species in the British Museum has shown them to be 

 at any rate closely allied to a species found in Guatemala, P. micros Bates (Biologia 

 Centrali-Americana, Coleoptera, 11. 2, p. 103). 



Hab. Oahu (Perkins). 



Adoketus Castelnau. 

 Adorctus Castelnau, Hist. Nat. 11. 1840, p. 142. 



(i) Adorctus tenuimaculatus Waterhouse. 



Adoretus tenuvnaculattis 'WaX&r]\ou'~,e, Tr. ent. Soc. London, 1875, p. 112. 



A. vitiensis Nonfried, Deutsche ent. Zeitschr. 1891, p. 268: Ohaus, Stettin, ent. 

 Zeit. 1904, p. 255. 



Nonfried gives only the Fiji islands as locality for this species, but Ohaus mentions 

 its occurrence at Honolulu, where the species is now abundant though apparently 

 only recently introduced. The species is evidently diffused by commercial operations. 

 Ohaus was not acquainted with the fact of the species being the tenuimaculatus 

 described long previously by Waterhouse from Japan. The form is perhaps not distinct 

 from A. compressus Weber. Ohaus records also A, viticusis from St Helena. The 

 only Adorctiis which I have seen from there is however A. z'crsutus Wollaston, which 

 is a very different species. 



Whether the geographical statements summarised in the above lines be really 

 correct is doubtful. Mr Perkins, who has now a considerable acquaintance with the 

 entomology of the Fijian islands, informs me that he has never met with Fijian 

 examples of A. tenuimaculatus. A species of Adorctus is \-ery abundant there, but it 

 is very different from A. tenuimaculatus. 



Hab. All the islands : introduced about 1896 (Perkins). Also in a large number 

 of other islands, as well as Ports and other localities, including St Helena, Hongkong, 

 Ceylon.
