1919, and 1 male (paratype) reared from the same host, 

 Kaimiiki, Oahu, Feb. 2, 1919 (Timherhike). This is un- 

 doubtedly an immigrant species, and was presumably intro- 

 duced with the host years ago from some part of the Orient. 

 It belongs to what appears to be a distinctly Oriental and 

 Australian group of Ana{jyru.s.

Before the descriptions of the four new species of A'aiilh- 

 oencyrtus published in Part I of this paper'^ had a])pear(Ml 

 in ])rint, three more were discovered on Oalni and Maui 

 mainly through the efforts of ^Mr. Bridv.-ell. it is becoming 

 evident, therefore, that ])rol)al)ly only a small beginning has 

 been made in elucidating our Hawaiian species, as there is 

 no apparent reason why each island of the group should not 

 be represented by one or more species. I"]) to the present 

 tiuie they have found only on Laysan. Oahu and .\l;iui. 

 although the introduced species, fullawayi. occurs on Hawaii. 



Our endemic species have been found chiefly if not 

 entirely in the tussocks of Errir/)-ofifi<t rariahllis. a coarse grass 

 which grows in great profusion on the steep sides of the bar- 

 ren foothills, and less luxuriantly in similar rocky places with- 

 in the native forests, as well as in regions at lower elevations 

 that have much Icvss rainfall. This grass is often infested with 

 a species of mealybug, I'rloni/niHs insnJaris Ehi'horn, which 

 serves as the host to these little parasites. Although apterKS 

 is the only species that luis been actually reared, there seems 

 to be no doubt that the othei's ;ilso parasitize this same mealvbiu;
