Apparently only those cocoons are stung in which the larvae 

 have not yet pupated; for in examination of quite a number 

 of cocoons, wherever larvae or pupae of Paraphelinus were 

 found, they were within a Haplogormto'pus larva, or its dried 

 up blackened remains. The length of period from oviposition to 

 emergence of adults is from 20 to 30 days. 



There are about the same number per host, whether it is 

 Haplogonatupus larva or Xiphidiurn egg. 12 or 13 is a com- 

 mon number per host. 



From parasitizing Locustid eggs which were hidden behind 

 leaf-sheaths of sugar cane, to parasitizing Dryinid larvae within 

 their cocoons on the cane leaves is quite a wide divergence of 

 habit. Apparently in this case, whichever happens to be most 

 convenient or accessible, or whichever the parasite first happens 

 to find, is what she deposits her eggs in. 



In discussion following this paper Dr. Perkins said that 

 although Mr. Koebele had collected Dryinids very extensively 

 throughout California, he had never bred a Proctotrupid from 

 them, which made Mr. Swezey's discovery all the more remark- 

 able. 



He also related that in course of correspondence with Dr. 

 Howard, the latter insisted that Giard's report of having bred 

 Aphelvriinae from eggs of Xiphidiurn v/as an error. It was 

 however, verified by Mr, Swezey when he bred an allied species 

 (Paraphelinus xiphidii) from Xiphidiurn eggs in Hawaii ; but 

 now Mr. Swezey's discovery that this Chalcid is also parasitic 

 on Haplogonatopus is still more remarkable. 



Mr. Kotinsky referred to what is already published in the 

 Proceedings of the Entomological Society of Washington rela- 

 tive to his breeding Syntomosphyruni esurus as a primary 

 parasite on Chilocoi'us sknilis pupae, though it had thitherto 

 been regarded as a secondary parasite.
