from Pseudococcus rirgatus (Cockerell), collected in Xovein- 

 hew 1918, on the gronnds of the Sugar Planter.s' Expevinient 

 Station. The species has thus become established from mate- 

 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 distribu- 

 tion is becoming cosmopolitan. Mr. J. E. Horton has in- 

 formed me by word of mouth that the species occurred in 

 Louisiana before its introduction into California (the deter- 

 mination, I believe, being by Mr. Girault), and I have pre- 

 viously recorded the species from Okitsu, Japan. It is now 

 my good fortune to be able to add Brisbane, Queensland, to 

 its known distribution, from specimens collected by the late 

 E. J. Vosler. On the whole, therefore, I am inclined to he- 

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

 South European. 



Encyrtus infelix (Embleton) is now known to be widely 

 distributed over the world and probably has followed its host. 

 Saissetiahemisphaerica (Targioni Tozzetti), into most regions 

 where the latter has penetrated. It AA^ould be impossible now 

 to point out the original home of either the parasite or its 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- 

 ber of our Proceedings from which I have seen this species, 

 I have identified the species since from Rewa, Fiji (F. Muir) ; 

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

 center of island (H. C. Kellers) ; and Manila, Philippine 

 Islands (Geo. Compere). 



A second species of Encyrtus^ very closely allied to E. hi- 

 colm- (Howard) but distinct in its much darker coloration 

 and longer beard on the cheeks, has been present in the local 

 collections for several years. This species, which may be 

 known as Encyrtus harhatus Timberlake was collected in Hono- 

 lulu by Alexander Craw in March, 1905, his specimens having 

 been reared from Sais-'<eiia hemisphaerica on ferns, and more
