INSECTS OF SAMOA. 



9. Pulvinaria psidii Mask.* 



Though. Doane and Ferris record this species from the islands, it was not 

 represented in the present collections except from New Hebrides, where it was 

 found on the leaves of lemon. 



10. Eucalymnatus tessellatus Sign.* 



This species was represented by its variety perforatus Newst. on cinnamon, 

 Malua, Upolu Island, ix.l924 ; and on Morinda citrifoUa, Apia, ix.l925. 



11. Lecanium psidii Grreen * 



Apia, V.1925, on Morinda citrifolia. The material was in bad condition, 

 but the characters which could be distinguished agree with specimens from 

 Ceylon. 



12. Coccus acuminatus (Sign.) 



Apia, 24.iii.1924, on pineapple ; Vila, New Hebrides, 24.vi.1925, on an 

 epiphytic fern. This species is very closely allied to C. diver sijpes Ckll., described 

 from material from the Philippine Islands, also from an epiphytic fern, and, 

 except for the strongly chitinised dorsum and rather more numerous pores the 

 latter could not be distinguished from C. acuminatus ; younger stages of C. 

 diversipes agree in every particular with C. acuminatus. At most, C. diversipes 

 should not rank as more than a variety of C. acuminatus (Sign.). 



13. Coccus frontalis (Green) * 

 On unidentified plant. 



14. Coccus hesperidus (L.) 

 Apia, 18.V.1924, on the leaves of Carica papaya. 



15. Coccus viridis (Green) * 



Apia, 28.iii., iv.l924, and Vailima, 600 feet up, 24.1.1924, in all cases 

 upon unidentified host plants.
