vlndis (Green). It has been reared at Honolulu from several 

 Coccids as a parasite of ScuteUisfa cyanea Mot;>!chulskv aud 

 Tomocera calif ornica Howard. 



Among our immigrant Encyrtids are two species of Aphij- 

 cus which have escaped being recorded hithertofore. The most 

 common species is Aphycus alberti Howard, which wa? de- 

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

 recorded from Southern California. As it is parasitic iu the 

 widely distributed Coccus hesperidum Linne, and in closely 

 allied species, it presumably has a much wider distribution 

 than is kno^AH 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 w^ell as into these Islands and California. 

 Alberti has been found here only recently, as apparently the 

 first specimen was reared by Mr. Swezey from Coccus longulus 

 (Douglas) on velvet bean from the Experiment Station 

 grounds in October, 1914. The other species is Aphycus cJavi- 

 ger Timberlake, described from Auckland, Xew Zealand, 

 l^othing is known of the habits of this species but as it is a 

 close ally of alberti it may have similar habits. The local 

 record is based on a pair of specimens collected by the writer 

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

 Oahu, on September 3, 1916. Three specimens were seen 

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

 of which leaped away before it could be captured. The Kadua 

 twig and surrounding shrubbery w^ere carefully examined for 

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

 discovered. 



Microterys I'otinshyi (Fullaway) and M. flavus (Howard) 

 are species of almost certain Oriental origin. Kotinshyi is very 

 closely allied to flavus which has been recorded from Ceylon 

 and which I have seen also from Japan, as well as other spe- 

 cies nearly identical from Fiji and the Philippine Islands.
