nish a basis for further research in this line. The systematic 

 arrangement used in the Fanna has been foHowed. It is to be 

 regretted that a nnmber of species have not been specifically 

 determined, and those that are new species are yet nndescribed. 

 The greater nnmber of these records of rearing of parasites are 

 from the island of Oahn, and chiefly from ITonolnln and the 

 monntain ridges near ITonolnln. 



Family Betiiylidae. 



Sierola molol-aiensis Ashni. — Reared from the sngar cane 

 bnd-moth, Ereunetis flavistriata Walsm. In one lot of cocoons 

 collected, it was found that one-third of the larvae had been 

 parasitized. The female Sierola stings the host larva and depos- 

 its one to several eggs on it, which soon hatch. In one instance 

 ■9 larvae were fonnd on one host caterpillar. The larvae obtain 

 their growth in a few days, feeding externally on the host ; they 

 then make their cocoons close together, often connected and with- 

 'ont distinct form. Probably the habits of other species are sim- 

 ilar, tho I have not had definite observations on any of them. 



Sierola dicliroma Perk. — Reared from a larva of Nacoleia 

 scotaea Hamps. 



Sierola flavocollaris Ashni. -and Sierola sp.— Reared from 

 Aristoteliaelegantior Walsm., a Gelechiid occnrring in the frnits 

 of Gouldia coriacea. 



Sierola n.sp. — Reared abundantly from mines of Gracilaria 

 ureraella, a leaf-miner in Urera sandwicensis. 



Sierola sp. — I have reared undetermined specimens of sev- 

 eral species of Sierola from Arcliips ca/)wcmi/5,( Walsm.), Capua 

 cassia Sw., Epagoge infaustana Walsm., Batrachedra n.sp. on 

 Elaplioglossum, Philodoria splendida Walsm. and Gracilaria 

 mahaella Sw. 



Scleroderma sp. — Reared from cocoons fonnd in dead wood 

 near the dried remains of larvae of Hyposniocoma chilonella 

 Walsm., which is a dead-wood feeder. I presume that the lar- 

 vae feed externally on their host the same as those of Sierola do, 

 tho I have not actually seen them. The cocoons are similar to 

 those of Sierola. 



Parasierola sp. — Reared from Gelechia gossgpiella 

 (Sandrs.) by Mr. Fullaway. 



Cepludonornia sp. — Reared from Eph-estia elufella lib. 

 (Ehrhorn).
