162. APANTELES SCHIZURAE Ashmead. 



Apantcles schizurae Ashmead, Proc. Eut. Soc. Wash., vol. 4, 1897, p. 162. 



Habitat. — New Hampshire; Massachusetts; Connecticut; New 

 York; Virginia; Illinois; Arkansas; Canada. Evidently very widely 

 distributed over the United States and Canada. 



Host.—Schizura unicornis Smith and Abbot ; Schizura^ species. 



Cocoons.— PsilQ buff to dirty whitish; gregarious, and arranged 

 parallel, side by side and closely cemented together; they are not 

 inclosed in loose silk. 



A large number of series of this species, including the types, are 

 in the National Collection, and show a wide distribution. Several of 

 these series are recorded from Schizura unicornis. No other hosts are 

 definitely known, although one large series reared by R. A. Cushman 

 at Falls Church, Virginia, is said to be from a Nctodontid on oak; 

 and two specimens from Bentonville, Arkansas, reared by D. Isely, 

 are from Schizura^ species. 



163. APANTELES CONGREGATUS (Say). 



Microgaster congregata Say, Boston .Toiu-n. Nat. Hist., vol. 1, pt. 3, 18.36, p. 262.

 Aimntcles (Protapanteles) congregatus Say, Viereck, Proc. U. S. Nat. Mus., 



vol. 44, 1913, p. 561. 

 Apanteles {Protapanteles) augustus Viekeck, Bull. 22, Conn. State Geol. 



and Nat. Hist. Surv., 1916, pp. 187, 194. 



Habitat. — United States and Canada. 



Hosts. — {Phlegethontius) Protoparce quinquemaculata Haworth; 

 P. sexta Johannsen ; Dolba hylaeus Drury ; Geratomia catalpae Bois- 

 duval; Sphinx chersis Hiibner; Ampeloeca rmjron Cramer; A. versi- 

 color Harris; Sphinx kalmiae Smith and Abbot; Ati^eus plebeja 

 Fabricius; Pholus pandorus Huebner; P. achemon Drury; Spheco- 

 dina abbotti Swainson; evidently a very general parasite of Sphingi- 

 dae, but has not been recorded from other families of Lepidoptera. 



Cocoons. — White; gregarious, but formed separately on the back 

 of the host caterpillar and not embedded in a mass of silk. 



The type of congregatus no longer exists ; but a neotype, which is 

 in the United States National Museum, has been established by 

 Viereck. Apparently utilis is a synonym, although it seems likely 

 that French had specimens of two species before him while describing 

 that species. In the opinion of the writer augustus, the type of 

 which has been studied, is identical with congregatus. 



The National Collection contains a vast amount of material of 

 this well-known and widely distributed species. It is not deemed 

 necessary to set forth here the recorded data for this material, since 

 the host records, all of which are included in the above list, are the 

 only matter of significance.
