350 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.58. 



National Museum collection: Malacosoma americana, Ilyphantria cu- 

 nea, Hemerocampa leucostigma, Tussock moth (Nebraska) , Hemileuca 

 lucina, Alabama argillacea, Autographa Irassicae, Bleptina species, 

 Anomis erosa, Diaphania fiyalinitatis, Diaphania quadristigvialis, 

 Ennomos subsignaria, Thyridopteryx eplieineraeformis, ArcJdps argyro- 

 spUa, Tortrix quercifoliana, Tortrix fervidana, Tortrix fumiferana, 

 tortricid on oak, tortricid on cedar, leaf-tier on oak, Acrohasis ruhri- 

 fasciella, Acrohasis letulella, Acrohasis Jcearfottella, Acrohasis caryal- 

 hella, Acrohasis caryaevorella, Acrohasis species, Eulia pinituhana, 

 Peronea hastiana, Peronea minuta, Peronea species on hornbeam, 

 Tmetocera ocellana, Cenopis pettitana, Polychrosis viteana, Evetria 

 frustrana, Epermenia cicutaella, Oxyptilus periscelidactylus , secondary 

 on lepodopterous larva through Rogas terminalis, and the coleopteran 

 Oncideres cingulata. The parasitism on Rogas terminalis was proved 

 by the writer by the finding in the Rogas cocoon of the larval exuvium 

 of the Itoplectis; but examination of the pupa of the coleopteran, 

 which was considerably shattered, failed to disclose any trace of the 

 parasite exuvium. 



The following additional hosts have been recorded : MineoJa iiulig- 

 enella,^ Cacoecia cerasivorana,^ Gingilia catenaria.^ The recording of 

 Phryganidea calif ornica in Insect Life (vol. 3, p. 462) is probably due 

 to a mistake in the determination of the parasite; specimens of Ito- 

 plectis hehrensii (Cresson) in the United States National Museum 

 bear the data given in the above record and are undoubtedly the 

 specimens referred to. Fiske reared conquisitor as a secondary para- 

 site of Malcosoma americana through several species of primary para- 

 sites (Limneria) Hyposoter fugitivus (Say) , Ameloctonus clisiocampae 

 (Weed), Rogas intermedins Cresson, Spilocryptus extrematis (Cresson), 

 and Iseropus coelehs (Walsh) (hsted as Pimpla inquisitor Say) , being 

 the immediate hosts. 



Fiske stated that this species oviposits in the pupa of the host. 



EPHIALTES (ITOPLECTIS) TEMNOPLEURIS, new species. 



Female. — Length, 14 mm.; antennae (broken); ovipositor, 4 mm. 



Very closely allied to conquisitor (Say), differing from the largest 

 specimens of that species practically only as follows: mesopleurum 

 with a sharply mcised, oblique furrow across the top of the prepectal 

 suture; propodeum more strongly, densel)^ punctate; abdominal 

 venter entirely black; apices of tergites narrowly piceous. 



Host.—Iphiclides ajax. 



Type locality. — -United States. 



Type.— C&t. No. 20909, U.S.N.M. 



Described from two females unlabeled except that the type bears 

 the host label. The paratype is very like the type.
