Francis Walker placed this family with the Eucharidas, with which it is unques- 

 tionably closely allied. It is, however, easily separated from the Eucharidx by 

 many salient differences, and I agree with Dr. Forster in considering it a distinct 

 family. It has some affinities allying it with the fannly Miscogasteridse, the affinities 

 existing also in the Eucliaridx and particularly through Cameron's genus Orasema. 



Cho'ysolampus Spinola belongs to this family and not with the Pteromalidas, 

 where Dr. Von Dalla Ton-e has placed it. His changing the well-known subfamily 

 Sphigigasterinse into Chrysolampinss, is therefore unnecessary and unwarranted. 

 Chrysolampus is identical with Lamprostylus Forster. 



The group attacks principally Lepidoptera, but will also attack other insects, as 

 I have bred Perilampus sp. from Chrysopa cocoons. 



The genera are not numerous and are characterized in the following table :
