amongst bananas on the bunch. It no doubt parasitizes this 

 species to some sHght extent. 1 have also reared it from Batra- 

 chedra rilcyi on a few occasions ; and from a Gelechiid (Stocber- 

 /liiiiis testaceous) which is very common, tlie larva feeding 

 amongst dead leaves at base of E'ernKuda grass and probably 

 other grasses. Dr. Perkins informs me that he has bred thi.s 

 Bracon from many Tineids, especially Erciiiictis siiniilaiis. 



The larva of this parasite emerges from the host caterpillai: 

 after the latter has spun its cocoon and is about readv to pupate ;. 

 then finishes eating the caterpillar and makes its own white silken 

 cocoon inside the cocoon of its host. The adult parasite emerges 

 in about two weeks. 



I once reared several of these parasites from larvae of Bafra- 

 chcdra rilcyi found stored in the nest of a wasp ( Odyiicnis uion-' 

 taiiiis). The wasp had collected parasitized larvae and stored 

 them up without injuring the parasitic larva inside while stinging 

 to paralyze the Batrachcdra larva. These parasite larvae then 

 emerged from the latter, after I had examined the wasp's nest ; 

 spun their cocoons and developed to maturity. 



ANTS. 



P/icidoJc incgarcpliala Fab. 



This species of ant is the common medium sized red ant. It 

 is always abundant in cane, often having its nests beneath the leaf- 

 sheaths. It destroys more or less of the young bud worms, also 

 larvae of the other moths which are treated of here. 



WASPS. 



Odyncnis Species. 



There are over one hundred species of native wasps of this 

 genus. They all prey upon the larvae of Lepidoptera, storing 

 them in their nests for the young wasps to feed on. Several 

 species have been observed in cane fields hunting for bud worms 

 and other Tineid larvae. On Kauai. 0. blackhunii: on Oahu,
