Upolu (Rechinger) : Apia, 2.iii. and x.1924 ; Vailima, 28.xii.1924. 

 " Samoa " (Swale). 



Originally described from material from Polynesia, this species appears to 

 be very widely distributed, tbough I liave seldom seen more than one or two 

 specimens from the same locality. My records include 

 India, Ceylon, Indo-China, Malay Peninsula, Sumatra, 

 Philippine Is., Cocos-Keeling Is., New Caledonia, EUice 

 Is., Marquesas Is., Tonga Is.. Tahiti, and Honolulu. 

 (Text-fig. 9.) 



As might be expected, an insect with such a wide 

 distribution exhibits considerable variation both in 

 colour and form. The types of the various authors 

 have been examined by me, and I find that specimens 

 from Polynesia are usually light browai, vdth sharply 

 rectangular hind angles to the prothorax, and the 



elytra distinctly striate and finely punctate. Indian Text-fig. 9.-Endyno7mna 

 and Malayan examples are generally darker, with pradieri rairmaire. 

 slightly obtuse hind angles to the prothorax, and the 



elytra less clearly striate and rather less finely punctate. In several cases I 

 have seen only single examples from the localities cited above, and where 

 there have been more, the characters are not constant, so that for the present 

 it seems best to regard them all as individiuals of one variable species.

Crossoglossa •politissima Chaudoir, Col. Nov., p. 20, 1883. 

 Upolu : Malololelei. 



Unfortunately I have not been able to see the type of this species, which 

 was obtained in New Caledonia. Except in one character, viz. the form of the 

 prothorax, the two Samoan specimens agree so well with the description that 

 I do not feel much doubt about the identification. It must be remembered too 

 that the author had no opportunity of revising his work, the descriptions of this 

 and of a few other species having been published posthumously. 



It was only shortly before completing the present paper that I was able 

 to examine the type of Parena bicolor Motchulsky, and to identify Phloeodromius 

 W. Macleay and Crossoglossa Chaudoir with Motchulsky's genus.
