hospitum (Holmgren). Northwestern Calif. Known only from the lectotype which was almost 

 certainly collected in the San Francisco vicinity, particularly in view of the fact that it 

 was collected by Kinberg (see Persson, 1971, p. 169).

 interruptum pterophorae (Ashmead). N. S. w. to interior Alaska, s. to Pa., Mich., and n. Calif. 

 Host: Archips rosanus (L.), Argyrotaenia citrana (Fern.), Choristoneura conflictana 

 (Wlk.), C. rosaceana (Harris), Cnephasia longana (Haw.), "Tortrix" on apple, "Tortrix" 

 on filbert, olethreutid on rose, Spilo7iota ocellana (D. and S.). D. interruptum 

 interruptum (Holmgren) is European, and I have not studied specimens of it other than 

 the lectotype; therefore, I have little basis for judging the soundness of the subspecific 

 distinction of the Nearctic population (see Townes, 1970). I am in agreement with 

 Horstmann (1973) that placement of the present species in Diadegma is more justifiable 

 than was Townes' (1970) placement of it in Tranosema, but I am not yet willing to 

 accept Horstmann's suppression of interruptum as a synonym of praerogator 

 (Linnaeus), in spite of his statement (1973) that the type of praerogator is a typical 

 interruptum male. My confidence in the opinions of Dr. Horstmann ordinarily being 

 complete, I would regard the question of the identity of praerogator as being settled 

 were it not for the fact that he indicated that the type was labeled "salicis," but 

 neglected to refute or otherwise discuss Linnaeus' indication that praerogator had been 

 reared from the lymantriid Leucoma salicis (L.). The manner in which the praerogator 

 type is mounted (see Roman, 1932) and the supposed deterioration of the specimen with 

 time would seem to necessitate (1) consideration of the Linnaean host record and (2) 

 comparison of the praerogator type with males of Hyposoter species which could be 

 expected to parasitize L. salicis. This seems all the more necessary in view of the fact 

 that I have seen specimens of a European species of Hyposoter, not colored unlike 

 interruptum, which were reared from a lymantriid, and which have cocoons agreeing 

 with Roman's description of the one mounted next to the praerogator type. 



Limneria pterophorae Ashmead, 1890 (1889). U. S. Natl. Mus., Proc. 12: 435. 9. Contrary 

 to Ashmead's statement, the label of the holotype reads: "From Tortrix on apple." 



Campoplex (Angitia) basizo7ia Viereck, 1924. Canad. Ent. 56: 67. 6. C. basizona had been 

 placed in Hyposoter by Townes (1945); the holotype was reared from Archips rosanus 

 (L.) and agrees well with other material of iyiterruptum pterophorae which I studied in 

 the Canadian Natl. Collection. N. syn.
