Phanerotoma sp. — Two or three specimens were reared from 

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

 ana. 



Microdus hairaiicola Ashm. — I have reared it from Tliijro- 

 copa sapindielJa Sw., Stoeberhinus testaceous BntL, Batrachedra 

 rileyi Walsm., Ereunetis flavistrlata Walsm., and Gelechia gos- 

 sypiella; and Dr. Perkins reared it from Ereunetis simulans 

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

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

 pate, finishes eating the caterpillar, then makes its o\ni white 

 oblong cylindrical cocoon .within the cocoon of the host. The 

 adnlt emerges in abont two weeks. 



Aponteles sp. — A species that first appeared in HonohiUi 

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

 from Opogona aurisquamosa (BntL), bnt it probably attacks 

 other Micros whose larvae feed in decaying vegetation on the 

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

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

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

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



Protapanteles hawaiiensis Ashm. — I have reared this only 

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

 which it often parasitizes qnite heavily. Of 33 larval cases 

 collected at one time, 70% contained parasite cocoons. There 

 is one parasite per host. 



Bracon omiodiroriim (Terry). — This was introduced from 

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

 leaf -roller and the cane leaf-roller, Nacoleia blachhurni and X. 

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

 once from either Archips postvittanus or Amorhia emigratelJn. 

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

 as 75 7f of the caterpillars in a bad outbreak of the cane leaf- 

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

 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 6-8 

 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
