 caudal aspect triangular; body short and stout. Seutellum 

 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. xantliocephalus Girault). 

 Axillae widely separated . . . . . . .... 



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

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

 Axillae barely separated . .

 Axillae distinctly separated 



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

 Three ring-joints. 



Marginal vein about twice longer than the stigmal; axillae a little 

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

 Abdomen distinctly petiolate. 



Antennae 11-jointed with one ring-joint, the club solid. Like Perilampus but not coarsely 

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



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

 was known. Once in the Pteromalidae with the Brachyscelidiphagini ; once in the Eurytomidae 

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

 and finally in the Perilampidae. The caudal tibiae 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 Pteromalidae, yet they seem a natural group.
