discovered that the parasite came from the puparium of a dip 

 terous insect occurring therein. He did not succeed in breed

 in Washington, four being males and the rest females. They 

 were observed in copulation, and both sexes appeared to be very 

 active. 



I append a tabulated list showing the host- relations of the 

 different species.

In the discussion Mr. Ashmead stated also that the question 

 of priority was of course settled if Newport published his de 

 scription in the Gardeners' Chronicle before Westwood. 



There followed a paper, read by Mr. Howard, recording the 

 conjoint observations of Messrs. Howard, Chittenden and 

 Marlatt. The communication in substance was as follows :
