 the material gathered by the Rev. William A. Stanton, S. .1. Under 

 each species credit has been given to the collector. ]n the Philippine 

 Journal of Science" Father Brown has given a list of the species of 

 Hymenoptera found in the islands and has cited several names sent 

 him by the late Dr. W. II. Ashmead which are manuscript names.

 the names used by Doctor Ashmead have been adopted.
