Note. Pteromaliis ater Ratzeburg is a syno- 

 nym of the type species C. cavigena T h о m s. Dr. W. H. 

 A s h ni e a d misunderstood the T h о m s о n 's description. 

 Therefore none of the american species described under 

 this generic name really belong to it, they are either Ha- 

 brocytiis Thorns, or Zatropis Crawford. 



31. Scutellum normal, convex Metapon Walk. 



(Psilocera Walk.) 

 Scutellum elevated and produced posteriorly into a co- 

 nical spine Acanthometapon A s h. 



32. Marginal vein thickened Xenocrepis Förster. 



yVo/^. Dr. G. May r described as the type-species /^wra 

 (Förster) and removed it from Miscogasteridae, where 

 it was incorrectly placed by W. H. As h mead as a 

 synonym of Caenocrepis T h о m s. From Scymnopha- 

 gus A s h m. the genus Xenocrepis differs only by having 

 the median carina on propodeum. Whereas this carina 

 is very slight one I see no reason to separate these 

 two genera. 

 Marginal vein slender 33 



33. Head subtriangular, eyes prominent, round. Praesterna large. 

 Pronotum with sharp margin anteriorly. Propodeum punctate, 

 with small round spiracles. Neck absent. Abdomen subovate, 

 wider than the tliorax, not boat-shaped . . . Cricelliiis T h о m s. 



Note. From Thomson's description. 

 Head more rounded, praesterna small. In other respects 

 not so shaped 34 



34. Mesonotum narrowed forward. Pronotum small, narrower 

 than the mesonotum, not forming the sharp margin anteriorly. 37 



Mesonotum not much narrowed forward. Pronotum 

 large, somewhat dilated to the sides, as wide as mesonotum, 

 with sharp anterior margin 35 



35. Neck on the propodeum wanting Neocatolacciis A s h. 



Neck on the propodeum distinct 36 



36. Abdomen shorter tlian the head and thorax united, strongly 

 compressed. Head and thorax covered with hairs . Bnicholnus Ash. 



Abdomen longer than the head and thorax united. Head 

 and thorax clothed with scales Zatropis Crawford. 



37. Propodeum with a subglobose neck, punctate. Marginal vein 

 long, a little more than twice the length of the stigmal vein 



Lophocomodia Ash. 

 Note. From Dr. W. H. As h mead's description. 

 Propodeum without a subglobose neck. In other respects
