Family Excyrtidak. 



Etipehnus di/sombrias Perk. — Reared from Phli/ctaeiiia o)n- 

 niafias Meyr. by Fullaway. 



Eupehnus spp. — I have reared three midetermined species 

 of this genus from pupae of three different hosts respectively: 

 Avisiotelia elegantior Walsm., Aristotelia niendax Walsm., Aris- 

 foteVtd u.sp. in galls on Gouldia, Heterocrossa subumbrata 

 Walsm,, Batrachedra sophroniella Walsm., 8-emnoprepia sp. 

 There is a large nimiber of native species of theis genus. Among 

 them different species have hosts among several different or- 

 ders, and there is no doubt but what several more species will 

 be found to parasitize Lepidoptera when their habits are studied. 



Family Eulophidae. 



Ompliale metalUcus Ashm. — Reared from Aristotelia n.sp., 

 a leaf-miner in Kadua; Heterocrossa subumbrata Walsm. : 

 Heterocrossa inscripta Walsm. ; Heterocrossa sp. in fruit of 

 Suttonia; Gracilaria epibathra Walsm., leaf -miner in Dubau- 

 tia; Gracitaria mabaella Sw., leaf-miner in Maba; Gracilaria 

 marginestrigata Walsm., the leaf-miner in Sida; Cryptophlebia 

 vulp-cs Walsm. in koa pods (Terry) ; Bedelia orchilella Walsm., 

 the sweet potato leaf-miner (Fullaway) ; Hyposmocoma litu- 

 rata Walsm. (Fullaway). The larva of this parasite feeds 

 singly, externally on the host larva and pupates by the remains 

 of the latter. It and other species of the genus kill an enormous 

 number of leaf-miners and other ]\Iicros. I have reared a num- 

 ber of close-related parasites from leaf-miners and other Micro 

 larvae. 



Oinplude sp. — Reared from the larval case of Hyposmocoma 

 liturata Walsm. 



j\[eIittot)ia Itawaiiensis Perk. — This minute insect is nor- 

 mally a parasite on Aculeate Hymenoptera, having been found 

 parasitizing Sceliphron caementarium (Drury), Pison hospes 

 Smith, M-egachile palmarum P., and Odynerus nigripennis 

 (Holm.). I have also found it breeding on the larvae of the 

 sugar cane bud-moth, Ereunetis flavistriata Walsm. In a lot 

 of 50 cocoons of this moth collected in cane at the Experiment 

 Station, H. S. P. A., 12% were parasitized by this insect. At 

 another time, of 27 cocoons there was a parasitization of 77%. 

 The eggs are laid externally on the host larva after it has made 

 its cocoon. They soon hatch, and become full-grown in about
