Family (/iiaixididae. 



Clialcis ohsriirata Walk. — This parasite was introdneed from 

 Japan by INIr. Koebele in 1S1>5, to prey upon the palm leaf- 

 roller (Nacoleia hJaclxhurni Bntl.) and the sngar cane leaf-roller 

 (Nacolela accepta Bntl.). Besides these hosts it attacks qnite 

 a nnmber of moths. I have reared it from Plusia chalcites Esp., 

 Simplicia i-nlxistalis Gnen., Phhjrf (tenia dcftpecta (Bntl.), P. 

 nlf/resrens (Bntl.), P. stellata (Bntl.), Archips posfviftanus 

 (Walk.), Amorhia onir/ratella Bnsck., Crocidosema plehinna 

 ZelL. CrypiopliJ-ehia Ulepida (Bntl.), and Ereinietis siwidans 

 (Bntl.) ; and it has been reared from Nacoleia monogona jNIeyr, 

 by Fnllaway. The Tortricid Amorbia emigratella has of late 

 years been its favorite host. The adult parasite stings and ovi- 

 posits in the pnpa of its host, where the parasite grows to matur- 

 ity. It gnaws its way ont at maturity. It is found to vary 

 greatly in size, according to the size of its host. The species of 

 Kaeolein and Plusia furnish food enough for a normal-sized 

 adult, but such small hosts as Phh/efaenia despecta and Crocido- 

 sema pJehiana furnish hardly enough food, and the parasites 

 emerging from pupae of these species are often very small. 

 There is never more than one parasite per host pupa. It is occa- 

 sionally reared from the puparium of a Tachinid (Chaetogaedia 

 monficola Big.) in the pupa of Plusia. This may be called an 

 accidental hyperparasitism.* 



Clialcis polynesialis Cam. — Beared from pnpa of Homoeo- 

 soma Jium-eralis (Bntl.). Probably parasitic on other Phycitids 

 such as flour moths, as it has been collected under circumstances 

 which would lead one to infer this. 



Hocl-eria sp. — This is an accidentally introduced parasite 

 which has become abundant of late vears. I have reared it from 

 pupae of Eph-estia ehifella Hb. and Corcijra cephalonica Stn., 

 cereal moths; Pijralix inauritialis Boisd., the Pyralid feeding in 

 old Polistes nests; and Stoeherhitias iestaccous Bntl., a Gelech- 

 iid whose larva feeds in dead grass and other decaying vegeta- 

 tion. Mr. Fnllaway has reared it from Gelecliia gossypiella 

 (Sandrs.), the pink cotton boll-worm.
