name is not known, for Cresson substituted Say's name in the 

 manuscript of Walsh's paper. It was redescribed many years 

 later by Ashmead as Pimpla pterophori. 



The Say species is obviously a true Ichneumon as indicated by 

 the very long ovipositor and the coloration of the legs. Support 

 of this idea was given by Say in his second reference to the 

 species when he stated that Pimpla humid a is similar in si/e 

 and form to pterelas. There is no specimen of this genus in the 

 National Museum that exactly agrees with the description. 



47. (Ichneumon) Amblyteles residuus (Say). 



Ichneumon residuus Say, Contrib. Maclur. Lye. Phila., vol. 1, 1828, p. 73 

 (Leconte ed., vol. 1, p. 377); Say, Boston Journ. Nat. Hist., vol. 1, 1835, p. 

 231 (Leconte ed., vol. 2, p. 688); Cresson, Trans. Am. Ent. Soc., vol. 6, 1877, 

 p. 184. 



The writers have accepted Cresson's interpretation of this 

 species. The specimen at hand appears to differ slightly in some 

 minor details from Say's description but the description is so 

 indefinite that it is doubtful if it would be possible to associate 

 any species with it which would more nearly fit it. 



48. (Ichneumon) Amblyteles suturalis (Say). 



Ichneumon suturalis Say, Boston Journ. Nat. Hist., vol. 1, 1835, p. 226 (Leconte 



ed., vol. 2, p. 685). 

 Amblyteles suturalis Cresson, Trans. Am. Ent. Soc., vol. 6, 1877, p. 193. 



Cresson 1 synonymized his propinquus with suturalis^ but a 

 paratype of the former in the National Collection seems to be 

 sufficiently different to warrant retaining the name propinquus. 



Amblyteles superbus Provancher, placed in synonymy with 

 suturalis by Davis, 2 is also a distinct species as indicated by notes 

 on the type made by Mr. Gahan. 



49. (Ichneumon) Amblyteles unifasciatorius (Say). 



Ichneumon unifasciatorius Say, Am. Ent., 1825, p. 48, pi. 22, fig. 4 (Leconte ed., 

 vol. 1, p. 48, pi. 22, fig. 4); Say, Boston Journ. Nat. Hist., vol. 1, 1835, p. 228 

 (Leconte ed., vol. 2, p. 686). [Mentioned in comparison with /. otiosus.\ 



Ichneumon niger Brulle, Hist. Nat. Ins. Hym., vol. 4, 1846, p. 302, male only. 



Ichneumon unifasciatorius Riley, 3d Ann. Kept. Ins. Mo., 1871, p. 71; Cresson, 

 Trans. Am. Ent. Soc., vol. 6, 1877, p. 155. 



The female of niger is apparently a different species since it is 

 not described as having the white-markings of hind tibia, pro- 

 notum, mesoscutum, scutellum, and first tergite, while the wings 

 are fuscous with black or blue-black venation. The description
