The insect figured by DeGeer is not the Ichneumon luteus Lin- 

 naeus as established by long usage. It was said by him to have been 

 parasitic on "une grosse chenille a double queue du Saule," with a 

 marginal reference to volume one of his own work (pi. 23, fig. 6). 

 The latter is the larva of the puss-moth, Dicranura vinula, the most 

 frequently mentioned host of Paniscus cepJialotes Holmgren, with 

 which DeGeer's description agrees very well. I, therefore, consider 

 [Ichneumon luteus DeGeer (not Linnaeus)] = Pa?i'Jscws cephalotes 

 Holmgren. 



The type citation should be as follows: 



PANISCUS Schrank. 



Faun. Boica, vol. 2, pt. 2, 1802, p. 316. One species. 



Type. — [Ichneumon luteus DeGeer (not Linnaeus)] =Pa?nsctts cephalotes Holm- 

 gren; Ichneumon luteus Rossi (by designation of Viereck, Bull. 83, U. S. Nat. Mus., 

 1914, p. 109); not tenable since Schrank did not mention Rossi's work in either 

 of his discussions of Ichneumon luteus; Paniscus glaucopterus Linnaeus (by desig- 

 nation of Gray, Ann. and Mag. Nat. Hist., ser. 3, vol. 5, 1860, p. 341), not orig- 

 inally included. (Monobasic). 



No recent revision of the North American (north of Mexico) species 

 of Paniscus has been published, the only keys to such species being 

 those of Provancher ^2. In the earlier article Provancher tabulated 

 eight species, seven described for the first time, to which he later ^' 

 added another. In the "Faune" he transferred five of these nine 

 to other genera and synonymized another with geminatus (Say) , so 

 that his second key included only three species: P. geminatus (Say), 

 albovariegatus Provancher, and alhatarsatus Provancher. Morley" 

 included six North American species, one new, in a key to American 

 species. 



Fifteen species from North America (north of Mexico) have been 

 described in or referred to the genus: One by Say, one by Olivier, 

 eight by Provancher, three by Ashmead, one by Viereck, and one 

 by Morley. Five of Provancher's have properly been transferred 

 to other genera, while the sixth is so treated on a later page of the 

 present paper. I have been unable to recognize the species of 

 Olivier and Morley because of insufficient description, although the 

 latter is included in the key to species; albovariegatus Pro- 

 vancher is included in the key but without entire assurance that 

 it is properly placed; appendiculatus Provancher is not included 

 in the key because the description applies equally well to at least two 

 of the species described as new, and I hesitate to apply Provancher's 

 name to either, because his typ is probably still in existence, 

 though probably with the label removed and placed with his gemi- 

 natus (Say), with which species he synonymized it.*^ Provancher's

 at this conclusion.
