Scutellum normal or al must extending caudad over propodeum only. 

 Antenna? 12-jointed. 



Club 3-jointed. Nonmetallic. 



One ring-joint. 



Axilla? a little separated; scutellum long'; abdomen globular, large; 

 hind tibial spur single. 

 Marginal, postmarginal and stigmal veins more or less equal, 

 not very long . . 



Perilampoides Girault (Type: P. hicolor Girault). 

 Marginal vein shorter than postmarginal and stigmal . . 



Melaxosomella Girault (Type: M. flavipes Girault). 

 No ring-joint. 



Axilla3 rather widely separated. Club not well differentiated; post- 

 marginal vein very short . . 



Epichrysomalla Girault (Type: E. atrieorpus Girault). 

 Club 2-joiuted; metallic 



One ring-joint. Postmarginal vein twice the length of the stigmal, sub- 

 equal to the marginal. Flagellum submoniliform. Scutellum 

 flat. Axilla? widely separated 



Parachrysomalla Girault (Type: P. aereifemur Girault). 

 Antennae 13-jointed. 



One ring-joint. Thorax densely punctate, the body strongly metallic. 



Antenna? normal, subelavate; abdomen short, strongly mflexed, from 

 caudal aspect triangular; body short and stout. Scutellum 

 convex, normal . . . . . . . . Perilampus Latreille. 



Two ring-joints. Thorax not densely punctate, the body nonmetallic. 



Marginal vein thickened, about twice longer than wide, more or less 

 equal to the stigmal and postmarginal. 

 Axillae barely separated 



Epiperilampus Girault (Type: E. xanthocephalus Girault). 

 Axilla? widely separated . . 



Neoperilampus Girault and Dodd (Type: N. niger Girault). 

 Marginal vein linear, distinctly more than twice longer than wide. 

 Axilla? barely separated 



Ccelocybelloides Girault (Type: C. aureus Girault). 

 Axilla- distinctly separated 



Perilampella Girault and Dodd (Type: P. flammeithorax Girault). 

 Three ring-joints. 



Marginal vein about twice longer than the stigmal; axilla? a little 

 separated . . Ccelocybella Girault (Type: C. variegata Girault). 

 Abdomen distinctly petiolate. 



Antenna? 11-jointed with one ring-joint, the club solid. Like Ferilnmpus but not coarsely 

 punctate. My interpretation of the genus . . . . . . Elatus Walker. 



The gall-milking genera I had placed into four distinct families before their position 

 was known. Once in the Pteromalida' with the Brachyscelidiphagini ; once in the Eurytomida? 

 as a new tribe; twice in the Cleonymidse, with which the forms are certainly closely allied; 

 and finally in the Perilampida?. The caudal tibia- should have two spurs in all the genera, but one 

 only is recorded for Perilampoides. Some of the genera, therefore, may have to be removed to 

 the Pteromalida?, yet they seem a natural group.
