90 . INSECTS OF SAMOA. 



more than twice as long as wide. Cauda straight, moderately stout. Tibial and 

 tarsal combs much as in M. heller si m., but the middle tibial comb more inter- 

 mediate in length. 

 Length : 2^ mm. 



Upolu : Tuaefu, ix.1923 (Swezey and Wilder). 



Tutuila : iv., vi.1918 (Kellers). 



Savaii : Safune, v. 1924 (Bryan). 



(Paratypes in Bishop Museum and in Coll. F. Muir.) 



Resembling the foregoing species in antennal structure and in the comb 

 formula, but differing entirely in colour. 



Family : RHIPIPHORIDAE.

Upolu : Apia, i.1925 ; Vailima, vi.1925 ; Malololelei, vi.1924. 



Tutuila : Pago Pago, 14.xii.1925 ; Amauli Road, 5.ix.l923 (Swezey and 

 Wilder) ; iv.1918 (Kellers). 



A very variable series, alike in size as in colour. Fairmaire gives the 

 length as from 4|-6 mm., whereas the specimens forming the series before 

 me range from 2|— 5 mm. In colour, two of the examples from Tutuila 

 and one from Upolu are almost uniformly rufocastaneous, while the others are 

 more or less infuscate, in some cases with vague indications of striping on the 

 elytra. Further examples in the British Museum from Fiji, the Tonga Is., 

 and the Ellice Is. include uniformly rufocastaneous and striped forms, while 

 one female is entirely black with greyish sericeous pubescence and the- usual 

 faint striping on the elytra. Provisionally I regard all of these as forms of one 

 variable species, but when longer series become available this opinion may have 

 to be revised. 



Family: OEDEMER1DAE. 



Schenkling, Coleopt. Cat. Oedem. (Junk, pars 65), 1915. 



In point of numbers, both of individuals and of species, the family 

 Oedemeridae occupies a prominent position in the coleopterous fauna of
