The following species are assumed to have come from the 

 Oriental, Polynesian or Australian regions, judging from their 

 kno"\\ii distribution, the range of their closest allies, or the dis- 

 tribution of their hosts or food-plants of the hosts. Blepyrus 

 mexicanus Howard, although described originally from llexico, 

 Texas and the Hawaiian Islands, I have seen from Manila, 

 Philippine Islands, and Mr. P. Van der Goot has informed 

 me that it also occurs in Java. Its host, Pseudococcus virgatus 

 (Cockerell) is known from Mauritius, Ceylon, India and the 

 Philippine Islands and undoubtedly has a wide range through- 

 out the Orient, whence it was probably introduced together 

 with its parasite into the Hawaiian Islands as well as into the 

 warmer parts of America. 



Pauridia peregrina Timberlake, a somewhat close ally of 

 Blepyrus, is the species recorded by Mr. Fullaway under the 

 names of Anagyrus species and Encyrtus species parasitic on 

 "Pseudococcus citri." I have studied specimens of this species 

 collected at Amoy, China, by Mr. C. P. Clausen, in Fiji by 

 Mr. Muir, in California by Mr. H. S. Smith, and have also 

 seen the characteristic wing mounted on a slide with another 

 Encyrtid from Manila, Philippine Islands. Its host, Pseudo- 

 coccus I'rauhniae (Kuwana)^ was described from Japan and is 

 presumably of Oriental origin. This parasite may have been 

 brought in with its host from the Orient years ago, or possibly 

 it was introduced from China by Compere in about 1908. 



Tnuaomastix ahnormis (Girault) was first introduced and 

 liberated in large numbers about Honolulu during the winter 

 of 1915-1916, and additional colonies were turned out later. 

 Its establishment was considered doubtful for a time because of 

 the usual scarcity of its regular host, Pseudococcus hrauhniae 

 (Kuwana). Recently, however, it has shown its adaptability 

 to local conditions, as Mr. Rosa has reared a few specimens 



s This is the species referred to in the hterature on Hawaiian Cocci- 

 dae as Pseudococcus citri. hut I have recently discovered that our species 

 is really P. krauhniac (Kuwana), in accordance with the distinctions 

 brought out by Ferris (The California Species of Mealy Bugs, Stanford 

 University Publications, University Series, 1918, p. 37, 45, pi. i, fig. 8).
