ART. 14 THE CHALCID-FLY GENUS CALLIMOME HTJBER 9 



remembered, however, that the very nature of the habits of the par- 

 asites may considerably affect their size. It is not unusual to find 

 individuals of the same species two or more times as large as others. 

 The sculpture of the propodeum is also a very valuable character. 

 In many species color alone may be safely used, but in most instances 

 it should be supported by structural differences.
