COCCID.E OF THE HAWAIIAN ISLANDS. 227 



5 T. ALBizzi^ (Maskell). — In the early nineties, terribly 

 destructive to all kinds of citrus, but wiped out by Crijptolcemus 

 montrouzieri. 



6. T. CALCEOLARiiE (Maskell). —Formerly causing consider- 

 able destruction to sugar-cane, but of little importance now, 

 being controlled by Cryptolcemus montrouzieri and Scymnus 

 deb His. 



7. T. ciTRi (Risso). — On orange and coffee, but of little im- 

 portance. 



8. T. FiLAMENTosus (Cockerell). — Introduced from Japan in 

 the early nineties on citrus, from which it soon spread to coffee 

 and other shrubs and trees. The citrus and coffee were so 

 infested by it that their destruction in the near future seemed 

 imminent ; nevertheless it has been practically exterminated by 

 Cryptolcemus montrouzieri. 



9. T. BROMELI.E (Bouche). — A consignment of pine-apples 

 was recently inspected, slightly infested with this, but was fumi- 

 gated and the mealy-bugs destroyed. It is possible, however, 

 that it may have been introduced before systematic inspection 

 was inaugurated. T. hroinelice is also known from India, South 

 Africa, and Massachusetts (under glass), on Hibiscus, Canna, 

 and mulberry, 



10. T. NiPiE (Maskell). — The cause of considerable destruc- 

 tion to alligator pears, guava, &c., but largely preyed upon by 

 Cryptolcemus montrouzieri. [10.] 



11. T. viRGATUs (Cockerell). — Leguminous trees were in some 

 instances entirely destroyed in former years, but the scale has 

 been rendered unimportant by Cryptolcemus.* 



12. AsTBROLECANiuM PUSTULANs (Cockerell). — This is the 

 Planchonia sp., formerly recorded by Prof. Koebele on Jacaranda 

 mimosifolia, Prosopis dnlcis, oleander, fig-tree, &c. It is con- 

 trolled by a Chalcid parasite. 



Sub-fam. Calymmatin^e (= Cogging). 



13. Chaetococgus bambus^ (Maskell). [=^ kermicus]. — On 

 bamboo. I have not seen it in the Islands. 



14. PuLviNARiA MAMMEiE, Maskell. — Controlled by Cryptolce- 

 mus montrouzieri, Vedalia cardinalis, and Hyperaspis sp. 



15. P. PsiDii (Maskell).— Prof. Koebele writes (5, pp. 107-8) : 

 " I myself must confess that nowhere have I ever seen a land- 

 scape so completely blackened by the fungoid growth, caused by 

 the honey exudation of the Pulvinaria scale in which this grows 

 [in the coffee districts] , as that of North Kona on my visit in 

 February, 1894. On my recent trip to the same place, all these 



'■' The last eight species are listed as Pseudococcus by Mrs. Fernald, and 

 were iornievly known sis Dactylopiiis ; both these names are synonj'mous, 

 and apply only to the cochineal inBect of Mexico {Ductijloxniis mexicamis, 

 Coccus cacti of many anthors).
