 mountain ridges near Honolulu. 



Family Betiiylidae, 



Sierola nwlol-aiensls Ashm. — Reared from the sngar cane 

 bud-moth, Ereiinefis flavistriafa AValsm. In one lot of cocoons 

 collected, it was found that one-third of the larvae had l)een 

 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 found 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- 

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

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



Sierola dichroma Perk. — Reared from a larva of Kacoleia 

 scotaea Hamps. 



Sierola flavocollaris Ashm. and Sierola sp. — Reared from 

 Aristotelia elegantior Walsm., a Gelechiid occurring in the fruits 

 of Gouldia coriacea. 



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

 ureraella, a leaf-miner in Urera sa7ulwicensis. 



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

 eral species of Sierola from Archips capucimis (Walsm.), Capua 

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

 Elaphoglossum, Philodoria splendida Walsm. and Gracilaria 

 mabaella Sw. 



Scleroderma sp. — Reared from cocoons found in dead wood 

 near the dried remains of larvae of Hyposmocoma 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 GelecJiia gossypiella 

 (Sandrs.) by Mr. Fnllaway. 



Cephalonomia sp. — Reared from Epli-estia elutella Hb. 

 (Ehrhorn).
