17. (Banchus) Hyposoter fugitivus (Say). 



Banchus fugitivus Say, Boston Journ. Nat. Hist., vol. 1, 1835, p. 247 (Leconte 



ed., vol. 2, p. 701). 

 Campop/ex fugitivus Riley, 1st Ann. Rept. Ins. Mo., 1869, p. 139 (parasite on 



Euchaetes egle). 



Limneria fugitiva Riley, 4th Ann. Rept. Ins. Mo., 1872, p. 41. 

 Limneria guignardi Provancher, Addit. Faun. Can. Hym., 1886, p. 87. 

 Limneria oedemasiae Ashmead, Proc. U. S. Nat. Mus., vol. 12, 1890, p. 436. 

 Ameloctonus fugitivus Ashmead, Smith: Ins. of N. J., (1899) 1900, p. 582. 

 Hyposoter fugitivus Gahan, Proc. U. S. Nat. Mus., vol. 48, 1914, p. 156. 



The specimen recorded by Say as having come from "a very 

 pretty cocoon which is somewhat cylindric, white, with two 

 maculated black bands" is not fugitivus as here recognized, since 

 the cocoon of fugitivus is spun inside the skin of the host and is 

 not banded with black. The cocoon that Say refers to may be 

 that of (Limneria) Hyposoter annulipes (Cresson), a very similar 

 species. 



18. (Banchus) Exetastes nervulus (Say). 



Banchus nervulus Say, Boston Journ. Nat. Hist., vol. 1, 1835, p. 246 (Leconte 

 ed., vol. 2, p. 700). 



A male specimen captured by C. W. Johnson at Princeton, 

 Maine, that agrees perfectly with Say's description is in the 

 National Museum. There are also a female from Savoy, Massa- 

 chusetts, and two females from Mt. Desert Island, Maine. The 

 species is closely allied to suaveolcus Walsh, but is at once dis- 

 tinguishable by its black hind tibiae and uniformly infuscate 

 wings. 



Neotype. The above male.
