* Meteorus angustipennis. Mr. Ashmead identified a number of species for me, 

 the names of which are followed by his authority, but of which I can trace no 

 published record. I enter these with some hesitation, crediting them to " Ashm. 

 MS." I have written both to Mr. Ashmead and Mr. Howard to gain information 

 about them. Mr. Howard writes that he cannot tell whether they are published, 

 as Mr. Ashmead has published so many short descriptive papers. Mr. Ashmead 

 does not remember about them, and has not time to look them up. The Hy- 

 menoptera will be getting into a rather chaotic state, if authors cannot them- 

 selves tell what they have described, It is time for a supplementary catalogue.
