(3) Ophion bilineatus Say, from Samia cecropia (cf. Hooker), Telea polyphemus (cf . Hooker). 



(4) Ophion bifoveolatus Bridle. A specimen from the Gypsy Moth Laboratory, said to 

 have emerged from a Callosamia promethea cocoon, but this is doubtful, as the species is a 

 regular parasite of Lachnosterna. 



(5) Enicospilus purgatus Say. From Telea polyphemus (cf. Felt). 

 The above species may be separated by the following key: 



Discocubital vein angularly bent and often appendiculate Ophion. 



Abdomen stout, not strongly compressed; eyes small, distant from base of mandibles 0. bifoveolatus. 



Abdomen usually strongly compressed; eyes large, extending nearly to base of mandibles 0. bilmeatus. 



Discocubital vein not angularly bent; straight or curved. 



Discocubital cell with one or more chitinous maculae Enicospilus. 



Discocubital cell without such macula Eremotylus. 



Discocubital vein arcuate; wings hyaline E. arctix. 



Discocubital vein sinuous; wings usually tinged with fulvous E. macrurus. 



Other ichneumonids bred from Saturnioids are the following : 



Limnerium fugitivum (Say), from Hemileuca maia (cf. Riley). 



Campoplex quadiimaculatus Ratzeburg, from Aglia tau (cf. Ratzeburg). 



Anomalon pyretorum Cameron (Entomologist, 1912, p. 195), from Saturnia pyretorum; 

 Hongkong. 



Anomalon exile Provancher ?, from Samia gloveri (cf. Howard). 



Anomalon signatum Gravenhorst, from Saturnia pavonia (cf. Mocsary). 



Allocamptus undulatus Gravenhorst, from Samia cecropia in Europe (cf . Taschenberg). 



Henicospilus merdarius Gravenhorst? from Samia cecropia in Europe (cf. Taschenberg). 



Metopius micratorius (Fabricius), from Saturnia pyri (cf . Rondani). 



Xanthopimpla punctator (L.), from Cricula trifenestrata (cf. Cotes). 



Pimpla sanguinipes Cresson, from Hemileuca olivise (cf. Ainslie). 



Theronia zebra (Vollenhoven), from Cricula trifenestrata (cf. Vollenhoven). 



Cryptus extrematis Cresson. Riley's MS. notes say he bred this from Samia cecropia and 

 Callosamia promethea. The males agreed with C. nuncius Say, the females with extrematis. 



Cryptus nuncius Say. Pergande bred males from cocoons of Samia cecropia received from 

 Nebraska. 



Hemiteles compactus Cresson, from Callosamia promethea, Pennsylvania (Pergande MS.). 



BRACONID.E. 



[Apanteles congregatus hemileucse Riley was bred from Hemileuca maia and Automeris io 

 (cf. Riley). Mr. Viereck writes that this is now called Apanteles (Protapanteles) hemileucse.] 



TRIGONALIDAE. 



[Lycogaster puttata Shuckard was bred in Berlin by Bischoff from pupa of Telea polyphemus, 

 but it appears to be a hyperparasite of Eremotylus macrurus (cf. Schulz, Zool. Annalen, IV, 



1911).] 



chalcidim; (sens, latiss.). 



[Perilampus maurus Walker, from ThyeUa tyrrhea (Cramer) (cf. Walker). 

 Phasgonophora (?) bauhiniss Gir aid, from Epiphora bauhinise (Guerin) (cf. Girard). 

 Spilochalcis mariss (Riley), from Telea polyphemus, Samia cecropia, Callosamia promethea, 

 and Philosamia walkeri (cf. Howard, etc.). 



Chalcis ovata Say, from Hemileuca olivise (cf. Ainslie). 

 "Cynips" bombycida Rondani, from Saturnia pyri (cf. Rondani).] 



DIPTERA. 



TACHINID.E. 



[Frontina jrenchii Williston. An efficient parasite of Samia cecropia. (Felt, 27th Report 

 N. Y., 1912); Felt figures a cecropia cocoon containing 41 puparia of F. jrenchii. F. jrenchii 

 was sent by Mrs. M. Treat to Dr. C. V. Riley, bred from Telea polyphemus.
