Phanerotoma sp. — Two or three specimens were reared from 

 Myelois ceratoniae Zell., infesting the pods of Acacia farnesi- 

 ana,' 



Microdus Jiaicaiicola Ashm. — I have reared it from TJiijro- 

 copa sapindieUa Sw., Stoeberhinus testaceous Butl., Batrachedra 

 rileyl Walsm., Er-eunetis flavistrlata Walsm., and GelecJiia gos- 

 sypieUa; and Dr. Perkins reared it from Ereimetis simidans 

 (ButL), and Hyposmocoma sp. The larva of this species 

 emerges from its host when the latter has spnn its cocoon to pu- 

 pate, finishes eating the caterpillar, then makes its o^^m white 

 ohlong cylindrical cocoon within the cocoon of the host. The 

 adnlt emerges in abont two weeks. 



Apanteles sp. — A species that first appeared in Honolnln 

 in 1910, and has now become abundant. I have reared it only 

 from Opogona aurisquamosa (Butl.), but it probably attacks 

 other Micros whose larvae feed in decaying vegetation on the 

 ground. Mr. Fullaway has also reared it from the same host as 

 above. I have not ascertained the feeding habits of the larva of 

 this parasite, but probably there is but one per host. Its white 

 oblong cylindrical cocoon is made in the cocoon of the host. 



Protapanteles hawaiiensis Ashm.— T have reared this only 

 from cocoons in the larval cases of Oecia maculata Walsm., 

 which it often parasitizes quite heavily. Of 33 larval cases 

 collected at one time, T0% contained parasite cocoons. There 

 is one parasite per host. 



Bracon omiodivorum (Terry). — This was introduced from 

 Japan by Mr. Koebele probably in 1895, to parasitize the plam 

 leaf-roller and the cane leaf-roller, Nacoleia hlacl'hurni and i\^. 

 acce^pta. I have also reared it from Hymenia recurvalis, and 

 once from either Archips postvittanus or Amorhia emigrateUa. 

 It mostly attacks the cane leaf-roller, however. Often as high 

 as 75 9f of the caterpillars in a bad outbreak of the cane leaf- 

 roller will be found parasitized by this Braconid. It is tlie 

 most important parasite on this pest. The parasite stings the 

 caterpillar so that it is paralyzed and remains so. The eggs 

 are laid on the exterior of the caterpillar, from 1 to 3, tho 0-8 

 are about the usual number. The eggs hatch in a day or two, 

 and the young larvae feed externally on the caterpillar, grow- 

 ing rapidly and becoming full-grown in about 3-4 days. The 

 cocoons are flattish and made on the leaf near the dried remains 

 of the caterpillar, more or less connected or in a mass. The
