vlndls (Green). It has been reared at Ilonohihi from several 

 Coecids as a parasite of ScufeUisia cijnnea ^lotseiinlskv an<l 

 Tomocera caJifontica Howard. 



Among- our innnig-rant Eneyrtids are two species of Aphij- 

 cus which have escaped being recorded hithertofore. The most 

 common species is Aphycus alherti Howard, whicli was de- 

 scribed from Sydney, Xew South Wales, and has since been 

 recorded from Southern California. As it is parasitic in the 

 widely distributed Coccus hesperidum Linne, and in closely 

 allied species, it presumably has a much wider distribution 

 than is known at present, and its place of origin will hardly 

 ever be determined exactly. Without much question, however, 

 it originated somewhere in the warmer regions of the Old 

 World and not necessarily in Australia, whither it may have 

 been introduced as well as into these Islands and Califoruia. 

 Alherti has been found here only recently, as apparently the 

 first specimen was reared by ]\Ir. Swezey from Coccus loiu/ulus 

 (Douglas) on velvet bean from the Experiment Station 

 grounds in October, 1914. The other species is Aplrycus chiri- 

 ger Timberlake, described from Auckland, Xew Zealand. 

 Xothing is known of the habits of this species but as it i- a 

 close ally of alberti it may have similar habits. The hx-al 

 record is based on a pair of specimens collected by the wi-iter 

 on a side spur of the main ridge leading up to Mt. Lanihidi. 

 Oahu, on Septeud:)er •'>, 191 (i. Thre(> s])ecini('iis were seen 

 nnming about on a slender withe of a species of Kadua, one 

 of which leaped away before it could be captured. The K<uhtii 

 twig and surrounding shrubbery were carefully eramiiud for 

 the host of these parasites, but no coecids of any kind were 

 discovered. 



Microterys kotinskyl (Fullaway) and M. flavus (Howard) 

 are species of almost certain Oriental origin. Kotinslxyi is very 

 closely alliiMl to fhirus wliich has been recorded from ("eylon 

 and which I have seen also from Japan, as well as other s])e- 

 cies nearly identical from Fiji and the Philippine Islands.
