recently Mr. Fullawav has reared a series from Saissetla nigra 

 (Xietner) on ferns at Honolulu. Barhatus has been collected 

 also by Mr. Muir at Pekalongan, Java, and on Larat, and by 

 Compere at Manila, so that it presumably was brought here 

 from some part of the Oriental or Indo-Malayan region. 



In the collection of the Board of Agriculture and Forestry 

 there is a single specimen of Homalotylus flaminius (Dalman) 

 collected years ago on the Island of Oahu by Koebele. In a 

 revision of the species of Homalotylus, which I hope will be 

 published soon in the Proceedings of the U. S. National Mu- 

 seum, I have referred all forms of the flaminius type from 

 Europe, Africa, Asia, and Australia to one species, to which 

 our local specimen belongs rather than to the Xorth American 

 species. It is therefore likely that the species was an acci- 

 dental introduction from the Orient or Australia, and as it has 

 not been found in recent years it apparently failed to become 

 established. 



Quaylea alienu Timberlake is another species whicli I l)e- 

 lieve originated in the Old World and possibly in Australia. 

 It is very closely related to a species common in California 

 which has been described recently by Mr. Giranlt as Cercliysius 

 whittien and which is the type of my new genus Quaylea. 

 Quaylea ivhittieri is the same species, I am almost positive, 

 which Ashmead called Hcmoicytius crairii but did not de- 

 scribe, although it has been mentioned in the literature several 

 times under that name by Isaac, Berlese and Silvestri ; and 

 imder the name of Cerchysius species by Prof. H. J. Quayle 

 and myself. If, as I suppose, it is the Heniencyrtu.s crairii 

 mentioned by Berlese and other writers it was purposely intro- 

 duced into California from Australia as a parasite of the black 

 scale, Saissetia oleae (Bernard), although it has ;nnce proved 

 to be a hyperparasite. Our local species, being closely allied 

 and having the same habits, probably also came from Australia 

 or some part of the Orient. It was recorded by Fullaway in 

 1913 as Hemencyrtus species, and possibly also under the name 

 of E>icy)ius s])ecies on Saissetia licniispJiaerica and Coccus
