8. Subgenus Periceros, new status 



Perissocerus Smith, 1877, Proc. Zool. Soc. London, vol. 1877, p. 412. Name 

 preoccupied. Type: Perissocerus plumicornis Smith; monobasic. 



Periceros Schulz, 1906, Spolia hymenopterologica, p. 99. New name for 

 Perissocerus. 



Neoxylonomus Szepligeti, 1914, Ann. Hist.-Natur. Mus. Nat. Hungarici, vol. 

 12, p. 421. Type: Neoxylonomus antennalis Szepligeti; monobasic. 



This is a Neotropic subgenus. It contains the genotype species, 

 listed above, and at least two undescribed or unidentified species. 

 The name Neoxylonomus antennalis Szepligeti 1914, is a duplicate in 

 the genus Xorides of Cyanoxorides antennalis Szepligeti, published in 

 the same paper. If it proves to be a species different from plumicornis, 

 it or the other antennalis will need a new name. We have not seen 

 the type. 



9. Subgenus Xorides 



Xorides Latreille, 1809, Historie Naturelle . . . des crustac6s et des insectes . . ., 

 vol. 4, p. 4. Type: Ichneumon indicatorius Latreille; monobasic. 



Xylonomus Gravenhorst, 1829, Ichneumonologia europaea, vol. 3, p. 819. Type:
