Francis Walker j)lace(l this family with the Kiirhar'nhi; with which it is unqiies- 

 tionahly closely allied. It is, however, easily separated from the Eiicharidx hy 

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

 family. It has some affinities allying it with the family 3Iiscof/asteridfe, the affinities 

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



Chrysolampus Spinola helongs to this family and not with the PteromalidR', 

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

 Sphigigasterinie into Chrysolampinse, is therefore unnecessary and unwarranted. 

 Chrysolampiis is identical with Laviprostylus Forster. 



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

 I have bred Perilampus sp. from Ghrysopa cocoons. 



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