INSECTS OF SAMOA. 



Is., New Caledonia, Mysol, etc., with one example labelled " Sandw. Is." (Fry 

 Coll.), no doubt in error for " Samoa Is." * Fairmaire records this insect as 



flying in the evening in the huts, and 

 as having once been taken on Hibiscus 

 flowers, but rare. 



35. Ananca bicolor Fairmaire. 



Op. cit., p. 456 (Nacerdes). 

 Samoa (Swale). 



Tutuila : Pago Pago, iv.1918 

 (Kellers). 



Specimens also from Tahiti, 

 Tonga, Ellice Is., and New Hebrides. 



Much resembles A. nigripennis 

 Fauv., of New Caledonia, but, in 

 addition to colour differences (the 

 head and antennae are flavous in the 

 latter, but black in A. bicolor), the 

 thorax in A. nigripennis, though very 

 similarly punctate has the space 

 between the punctures smooth and 

 shining ; in A. bicolor the general surface of the thorax is finely alutaceous. 



Text-fig. 8. — Ananca kanack Fairmaire. 



36. Ananca decolor Fairmaire. 

 Op. cit., p. 455 (Nacerdes). 



Upolu : Apia, v., vi.1924, 14.ix.1923 (Swezey and Wilder) ; Lalomanu, 

 xi.1924 ; Tafua Volcano, 1917 (Swale). 



Tutuila : Pago Pago, 12.viii.1924, 30.ix.1923 (Swezey and Wilder). 



The Samoan series of this species differs constantly in coloration from 

 those from Tahiti, the Ellice Is., and the Marquesas group, being darker 

 (brownish), but appears to agree with them in sculpture. Schenkling (loc. cit.) 

 considered S. decolor (probably incorrectly identified) to be practically 



See Uloma cavicollis (p. 76).
