 Ichneumon devinctor Cresson, Trans. Am. Ent. Soc., vol. 6, 1877, p. 174. 



The above synonymy is by Cresson. 



37. (Ichneumon) Amblyteles duplicatus (Say). 



Icheumon duplicatus Say, Boston Journ. Nat. Hist., vol. 1, 1835, p. 230 (Leconte 



ed., vol. 2, p. 688).

 Ichneumon signatipes Cresson, Trans. Am. Ent. Soc., vol. 6, 1877, p. 180. 



A series of six females (signatipes] and two males (duplicatus} 

 reared by A. B. Champlain from the same host at various 

 localities in Pennsylvania shows these two to be sexes of the 

 same species. The antigeny is much the same as in the closely 

 allied W -album (Cresson). 



38. (Ichneumon) Theronia? hilaris Say. 



Ichneumon hilaris Say, Contrib. Maclur. Lye. Phila., vol. 1, 1828, p. 71 (Leconte 

 ed., vol. 1, 1859, p. 376). 



The form of the areolet would exclude this species from the 

 ' Joppinae and suggests Theronia. The male of Theronia melano- 

 cephala Brulle comes very close to the description, but the face 

 is not distinctly yellow but rather reddish in the middle and 

 black at the sides. The specific name is a primary homonym, 

 being preoccupied in Ichneumon by hilaris Gravenhorst. 



39. (Ichneumon inquisitor Say [not Scopoli])=Epiurus inquisi- 



toriella (Dalla Torre). 



Ichneumon inquisitor Say, Contrib. Maclur. Lye. Phila., vol. 1, 1828, p. 71 



(Leconte ed., vol. 1, p. 375). 

 Cryptus inquisitor Say, Boston Journ. Nat. Hist., vol. 1, 1835, p. 233 (Leconte 



ed., vol. 2, p. 690). 



The true status of this species has already been pointed out 

 by Cushman; 1 as has also that of Cryptus inquisitor var. a. The 

 latter is Iseropus coelebs Walsh. The synonymy of both is given 

 in detail in the reference cited. 



40. (Ichneumon) Amblyteles malacus (Say). 



Ichneumon malacus Say, Contrib. Maclur. Lye. Phila., vol. 1, 1828, p. 72 

 (Leconte ed., vol. 1, 1859, p. 376); Boston Journ. Nat. Hist., vol. 1, 1835, p. 

 227 (Leconte ed., vol. 2, 1959, p. 6S5).
