despccta (Butl.) by Perkins and Fnllaway, and from Xacoleia 

 continuatalis (Wall.) by Fnllaway. The larvae live singly in 

 the host larvae. The latter spins np for pnpation bnt fails to 

 pnpate, as about that time it has been nearly consumed by the 

 parasite within, which soon breaks out of the remains of the 

 host, finishes eating it except the skin, and makes its cylindric- 

 oval cocoon within the cocoon made by the host. The adult 

 emerges therefrom in about ten days. The habits of the related 

 genera: Cremastus, Pristomerus, are similar to this. 



Pristomerus hawaiiensis Ashm. — Reared from Nacoleia ac- 

 cepta (Butl.), Phlyctaenia chytropa Meyr. and Hetevocrossa sp. 

 in Olea seeds. Mr. Fnllaway has reared it from Omphisa anas- 

 tamosalis Guen. and Gelechia gossypiella. I have seen the males 

 of this species in swarms in the air like one often sees gnats. 



Lathrostizus insularis Ashm. — Breeds in the larvae of Plo- 

 dia interpundella Flub., Ephestia eluiella Hub., and probably 

 other flour moths. The adult parasite emerges from the pupa 

 of the host. 



Family Beacoxidae. 



Chelonus hlackhurni Cam. — This species has quite a num- 

 ber of hosts: Hymenia recurvalis Fab., Lineodes orhrca 

 Walsm., Homoeosoma humeralis (Butl.), Phthorimaea opercu- 

 lella (Zell.), Batrachedra cuniculator Busck., Phlyctaenia des- 

 •pecta (bred by Perkins), Gelechia gossypiella (bred by Perkins 

 and Fnllaway), Petrochroa dimorpha Busck (Perkins). The 

 larva of this parasite lives singly in the host larva. It emerges 

 from it after the latter has made its cocoon for pupation, and 

 makes its own white oblong cylindrical cocoon wdthin that of 

 its host. I do not know whether oviposition takes place the 

 same with this species as with Chelonus te.ranus as reported by 

 W. D. Pierce and T. E. Holloway in Journal of Economic Ento- 

 mology, Vol. 5, pp. 426-428, 1912. According to their obser- 

 vations C. texanus oviposits in the egg of the host, but does not 

 prevent the hatching of the egg. The host larva grows with the 

 parasite in it, and later is killed, and the parasite larva emerges 

 and makes its cocoon as our species does. 



Phanerotoma hawaiiensis Ashm. — Reared from StoeherJii- 

 nus testaceous Butl. Its white oblong cylindrical cocoon was 

 wdtliin the cocoon of the host. It probably parasitizes other 

 related Micros.
