 TAXONOMIC NOTES 



By R. A. CusHMAN 



Entomologist, Bureau of Entomology, United States Department of Agriculture 



This paper consists of the descriptions of 1 new genus, 9 new 

 species, and 1 new variety of Ichneumonidae and notes on 10 other 

 species, one of which is assigned a new name. 



Most of the species discussed have been reared from insects of 

 economic importance. All but two are North American, these being 

 European species that have been reared at the Gipsy Moth Parasite 

 Laboratory, Melrose Highlands, Mass., during a study of the para- 

 sites of the introduced birch leaf -mining sawfly, Phyllotoma nem- 

 orata (Fallen). 



Genus HOPLISMENUS Gravenhorst 



HOPLISMENUS RUTILUS (Cresson), new combination 



IcJineumon rutilus Cresson, Proc. Ent. Soc. Philadelphia, vol. 3, p. 169, 1864; 

 Trans. Amer. Ent. Soc, vol. 6, p. 185, 1877, female. 



Genus AMBLYTELES Wesmael 



AMBLYTELES PRGPITIUS (Cresson). new combination 



Ichneumon propUius Cresson, Trans. Amer. Ent. Soc, vol. 4, p. 156, 1872 ; vol. 6, 

 p. 182, 1877, male 



Two males and three females reared at the Gipsy Moth Parasite 

 Laboratory in June, 1931, from pupae of Cinclidia harrisii Scudder, 

 collected at Lynnfield, Mass., and Deering, N. H., together with the 

 type male and five other females from localities ranging from Hamp- 

 ton, N. H., to Champaign, 111., are before me. One of the latter was 

 reared by Dr. A. S. Packard from Phyciodes tharos (Drury). 



The apices of the second and third tergites in the type are not 

 blackish as described by Cresson but a little darker reddish than the 

 surface generally. The scutellum and first tergite are narrow, the 

 former subdistinctly margined laterally well beyond the base and 

 the latter barely half as broad at apex as long. The areola is dis- 

 tinctly separated from the basal median area, not extending to base 

 as described by Cresson. The areolet is not triangular, as described, 

 but pentagonal, with the second recurrent well beyond the middle. 



Except that the Massachusetts males are somewhat stouter and 

 have the scutellum somewhat broader and margined at base and the
