INSECTS OF SAMOA. 



Chariotheca, Amarygmus among the Tenebrionidae, Pelecotomoides in the Rhipi- 

 phoridae, Callirhipis, etc., appears to support the inference that the fauna of 

 our region is a development of a branch originating in the Indo-Malay region 

 and running eastward through Melanesia to Polynesia. So far as it is possible 

 to judge from the limited fauna here considered, there seems little evidence 

 of any important contribution having been received from Australia, no genera 

 peculiar to that fauna, or their derivatives, being represented ; such features 

 as they have in common, e.g. Carphurus, would appear to be due to a common 

 origin in the Papuan region, rather than to an independent origin in Australia. 



Collections of greater or less extent from the Samoan Group have been 

 received at the British Museum from the Rev. S. J. Whitmee, 1875, 1876, 1890, 

 and 1897 ; Dr. H. Swale, 1917, 1918, 1920 ; Dr. F. W. O'Connor, 1920 ; while 

 for the purposes of this present work further collections have been kindly lent 

 by the authorities of the Bishop Museum, Honolulu (Coll. Swezey and Wilder, 

 E. H. Bryan, Jr., A. F. Judd), and by Mr. F. Muir of Honolulu (Coll. H. C. 

 Kellers). 



For bibliography, the reader is referred to the respective parts of Junk's 

 Coleopterorum Catalogus where published, only the original citation, with a 

 reference to a figure, and to papers subsequent to Junk's work being given in 

 the present paper. 



The types of new species, except when otherwise stated, are in the British 

 Museum. 



The following table shows the distribution, so far as it is known, of the 

 Samoan fauna among the Samoan Is., and in other parts of the Pacific.
