is extremely closely allied to the genotype, Stylocryptus brevis 

 (Gravenhorst). 

 Neotype. A female from province of Quebec, Canada.

 Hemiteles tenellus Timberlake, Proc. Haw. Ent. Soc., vol. 3, 1918, p. 400. 



The above synonymy, except of nemativorus Walsh, is that 

 proposed by Timberlake, who, however, admits that there may 

 possibly be more than one species. Walsh's description is of an 

 insect entirely within the range of color variation of tenellus. 



31. (Ichneumon) Exetastes bifasciatus (Say). 



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



(Leconte ed., vol. 1, 1859, p. 377). 

 Cryptus? bifasciatus Cresson, Trans. Am. Ent. Soc., vol. 6, 1877, p. 209. 



Further discussion of very suggestive character descriptive of 

 this species is given by Say in his description of Cryptus calip- 

 terus. This leaves no apparent doubt that the species is an 

 Exetastes allied tofascipennis Cresson. 



An unnamed species heretofore confused in the National Col- 

 lection withfascipennis agrees very well with Say's description. 

 It differs from fascipewiis principally in having the face rela- 

 tively shorter; the malar space shorter than basal width of 

 mandible; clypeus nearly twice as broad as long; ovipositor 

 fully as long as first tergite; and the wings more distinctly 

 fasciate. 



Neotype. A female from Washington, District of Columbia, 

 taken by T. Keleher. 



Other specimens are from Georgia, Florida, and Texas.

 1835, p. 228 (Leconte ed., vol. 2, 1859, p. 686).
