Grapholitlia olivaceana, and Coleophora cinerella may be the true 

 i/K/uisitor Say, while these are possibly and that from Mineola 

 indigenella is undoubtedly Epiurus inda gator (Cresson), a species 

 commonly reared from the last mentioned host. The weevil, 

 Mononychus vulpeculus, reported by Hamilton (Ent. News, V, 

 1894, p. 288) as heavily parasitized by inquisitor, is a rather 

 unusual but not necessarily impossible host for a parasite nor- 

 mally attacking lepidopterous larvae, and it may be that this 

 again was the true inquisitor Say. Glover's record (Kept, Comm. 

 Agr., 1866, p. 41) of Thyridopteryx ephemeraeformis as a host of 

 inquisitor is obviously due to a misdetermination of the parasite; 

 for he says "a small yellow-banded ichneumon fly," and his 

 figure published in his "Illustrations of North American En- 

 tomology," Plate I, figure 5, could only represent Itoplectis 

 conquisitor (Say), a very common parasite of Thyridopteryx. 

 The inquisitor recorded as reared from spider egg-cocoons can be 

 nothing but a species of Tromatobia, probably a dark form of 

 T. rufopectus (Cress.). Riley's record (Ins. Life, I, p. 161) of 

 Gnorimoschema gallaesolidaginis as a host of this species is proba- 

 bly based on a misdetermination of Epiurus pterophori (Ashm.). 

 Most of the records of the rearing of inquisitor from such hosts 

 as Liparidae and Lasiocampidae should be credited to Iseropus 

 coelebs (Walsh). Such records refer to (Orgyia) Hemerocampa 

 leucostigma, (Clisiocampa) Malacosoma americana, etc. Coquil- 

 lett's record (Bur. Ent. Bui. 32, p. 30) of Clisiocampa constricta 

 as a host of inquisitor at Los Angeles, Calif., apparently forms 

 an exception, as what are undoubtedly the specimens on which 

 this record was based are in the National Museum and belong 

 to an undescribed species of Iseropus. 



Ashmead's Pitnpla (Itoplectis) orgyiae, except for its smaller 

 size, is identical with coelebs, and additional California material 

 from the same host as the types do not differ even in this respect. 



Viereck's Epi.nrns ~bruneifrons differs from coelebs only in the 

 color of the face in the male, and is at most worthy of varietal 

 rank. The other two characters mentioned by Viereck are varia- 

 ble in the large series of coelebs examined. 



Provancher's l><ixxnx ct/lindricus was declared by Davis (Proc. 

 Acad. Nat, Sci. Phil., 1894, p. 190) to be synonymous with 

 l'r.n/l>l<i inquisitor (Say), and examination of the type by Mr. 

 Rohwer showed it to be the male of coelebs, not of annulipes 

 r.rulle as listed by Dalla Torre. 



\Ve therefore have the following synonymy: 



Epiurus inquisitoriella (Dalla Tonv 



Ichneumon inquisitor Say, Contrib. Mad. Lye. Phil., II. l^-"\ p. 71.
