from Pseudococcus vlrrjatus (Cockerell), collccU'd in \c\cm- 

 Iter, 191S, on the grounds of" the Suiiai- Plantcr;s^ Exivi-iincnr 

 Station. The species has thus become established from male- 

 rial received from California, whither it was brought original- 

 ly from Sicily. It seems doubtful that the species is endemic 

 in southern Europe, however, for its present known distriliu- 

 tion is becoming cosmopolitan. Mr. J. R. Horton lia> in- 

 formed me bj word of mouth that the species (X'curred in 

 Louisiana before its introduction into California (th(> deter- 

 mination, I believe, being by Mr. Girault), and T have ])re- 

 viously recorded the species from Okitsu, Ja])an. It is now 

 niv good fortune to be able to add Brisbane, Queenshuid. to 

 its known distribution, from specimens collected by the late 

 E. fJ. Vosler. On the whole, therefore, I aui inclined to be- 

 lieve in its Oriental, or possibly Australian origin, instead of 

 South European. 



EncyHu.'^ infclix (Embleton) is now known to be widely 

 distributed over the world and probably has followed its host, 

 Saifisefia hemispliacrica (Targioni Tozzetti), into most regions 

 where the latter has penetrated. It Avould be im]iossiide now 

 to point out the original home of either the parasite or irs host 

 with exactitude, yet I believe this must have lain somewhere 

 in the tropics of the Old World and probably in the Asiatic 

 region. In addition to the localities recorded in the last num- 

 bei" of our Proceedings from which I have seen this species, 

 I have identified the species since from Rewa, Fiji (E. Muir ) : 

 Brisbane, (Queensland (E. J. Vosler) ; Tutuila, Samoa, near 

 center of island (H. C. Kellers) ; and Manila, Phili])])ine 

 Islands (Geo. Compere). 



A second species of Encyrtiis, very closely allied to K. hl- 

 colar (Howard) but distinct in its much darker coloratiou 

 and longer beard on the cheeks, has heen present in tli'' hx-al 

 collections for several years. I'his sjxH'ies, which may be 

 known as Encyvins harhatus Timberlake was collected in Hono- 

 lulu by Alexander Craw in ^Nlarch, 11)05, his specimens having 

 lieen reared from Sdisscfla liemispha/'rica on fern.-, and more
