is so brief that it is impossible to fix on any of the species 

 described by Cresson or others as the same, although it might 

 be either viola Cresson or malacus Cresson or even a small 

 specimen of maurus Cresson. 



50. (Ichneumon) Itamoplex vinctus Say. 



Ichneumon vinctus Say, Contrib. Maclur. Lye. Phila., vol. 1, 1878, p. 70 (Leconte 



ed., vol. 1, 1859, p. 375). 



Cry plus americanus Cresson, Proc. Ent. Soc., Phila., vol. 3, 1864, p. 297. 

 Itamoplex americanus Ashmead, Smith's Ins. N. J., (1899) 1900, p. 570. 



Cresson failed to recognize this species and simply included it 

 under "Desiderata" in his "Classification of the North Ameri- 

 can Ichneumonides." 



The male of Itamoplex americanus (Cresson) usually has a 

 blackish line on each side of the middle of the face, but the dis- 

 tinctness of these lines varies greatly, and the National Collec- 

 tion contains two specimens which lack them and agree per- 

 fectly with the description of vinctus. 



Neotype.A male collected May 29, 1895, by Hugo Kabl at 

 Lawrence, Kansas. 



Further synonymy is given in Dalla Torre's "Catalogus 

 Hymenopterorum " under Cryptus americanus Cresson. 



51. (Ophion) Labrorychus analis (Say).

 Erigorgus analis Viereck, Conn. Hym., 1917, p. 281. 



Norton was certainly correct in placing this in the (Anomalini) 

 Therionini, and specimens determined by Ashmead as analis 

 and confirmed by Gahan by comparison with Norton's specimen 

 run to Labrorychus. 



52. Ophion bilineatum (Say).

 the writers.
