INSECTS OF SAMOA. 



20. Oopsis albopicta, sp. n. 



Ab 0. nutatore F., cui proxime affinis dift'ert statura minore, pube grisea 

 multo tenuiore ; capite, lateribus pectoris, vittis pronoti (antice saepe abbre- 

 viates) guttisque elytrorum (saepissime elongatis) albo-tomentosis. 



Long, corporis 6-7 mm. 



Ten specimens. Upolu : Apia, iii., vi.1924, ii. 1925 ; Malololelei, 

 14-30. vi. 1924 ; Lalomanu, xi.1924 (Buxton and Hopkins). Tutuila : Pago 

 Pago, 24.ix.1923 ; Amauli, 6.ix.l923 (Swezey and Wilder). Manua Is. : Tail, 

 20.ii.1926 (Judd). 



This form is probably the same as that which Fairmaire (Ami. Soc. Ent. 

 Fr. (6), 1, p. 478, 1881) regards as a variety of 0. nutator, or (Revue Zool. (2), 2, 

 p. 117, 1850, as its male. Further investigations in the field are necessary to 

 decide the matter. 



0. albopicta is somewhat intermediate between 0. nutator and 0. brunneo- 

 caudata Fairm. 



21. Oopsis striatella Fairm. (?). 



Oopsis striatellus Fairmaire, Pet. Nouv. Ent., 2, p. 289, 1879 ; Ann. Soc. Ent. Fr. (6), 1, 



p. 477, 1881. 



Two specimens, Upolu : Aleipata, 10.iv.1924. 

 Also one specimen, Tonga : Vavau, 9.iii.l925. 



The examples before me appear to agree well with Fairmaire's descriptions. 



22. Oopsis oblongipennis Fairm. (?). 



Oopsis oblongipennis Fairmaire, Rev. Zool. (2), 2, p. 118, 1850. 



Nine specimens, Upolu : Apia, 24.i.l924 ; Malololelei, 2000 ft., 25.ii.1924 

 (Buxton and Hopkins). Tutuila : Amauli, 5-6.ix.1923 (Swezey and Wilder), 

 xii.1918 (Kellers). Manua : Tau, 20.ii.1926 (Judd). 



Also two specimens, Tonga : Vavau. 



Individuals with the apex of the elytra obliquely truncate, and the outer 

 angle of the truncature somewhat produced have been referred to the present 

 species, and specimens with transversely truncate apex of the elytra to 0. 

 striatella. All other distinctions between the two species seem to be variable.
