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

 them different species have hosts among several different or- 

 ders, an<l there is no doubt but what several more species will 

 be found to ]iarasitize Lepidoptera when their habits are studied.

Oiiiplidlc incf alliens Ashm. — Reared from AristoteJ'ia u.sp., 

 a leaf-miner in Kadua; Ileterocrossa subumhrafd Walsm. ; 

 Heterocrossii inscripta Walsm. ; Heterocrossa sp. in fruit of 

 Suttonia ; Gracilaria /'pibathra Walsm,, leaf-miner in Dubau-

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

 vulp^s Walsm. in koa pods (Terry) ; Bedelia orchilella Walsm., 

 the sweet ])otato leaf-miner (Fullaway) ; Hyposmocoma litii- 

 rafa 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 Micros. I have reared a num- 

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

 larvae. 



Omphalc sp. — Reared from the larval case of Hyposmocoma 

 JHuraia Walsm. 



MeJiitobia liairaiiensls Perk. — This minute insect is nor- 

 mally a parasite on Aculeate Hymenoptera, having been found 

 parasitizing Seclipliron caementarium (Drury), Pison hospes 

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

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

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

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

 Station, H. S. P. A., 12% w^ere 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. Thev soon hatch, and become fuU-ii'rown in about
