 This family very closely resembles tlie family Pteromalidse,, and the two are sep- 

 arated with difficulty, the only reliable character to separate them being the num- 

 ber of apical spurs on the hind tibiae. In this family the hind tibise have two apical 

 spurs, while in the Fteromalidx. there is but one apical spur. It is a good character 

 but not easily seen in the smaller species, and the greatest care and caution must 

 be exercised in examining specimens before they can be placed in their proper fam- 

 ilies. A very strong lens is required to see the spurs and sometimes it will be found
