to Haemorrhagia ; S. Hylas Fab., as we have already remarked, and 

 probably also 8. Gunninghami Boisd. sp., should be referred to Cepho- 

 nodes Hiibner. 



A mutilated specimen from the most northern parts of Canada West 

 is before us, which evidently forms a distinct species from H. thyshe. 

 In this species, which is altogether slenderer than its congener, the 

 inner margin of the terminal band on anterior wings is nowhere den- 

 ticulate in the interspaces, but is medially, somewhat inwardly, pro- 

 duced. "We are not indisposed to regard this as Kirby's species, but 

 the inferior condition of the specimen prevents all conclusions. The 

 discal cell is crossed by a longitudinal scale line, the species belonging 

 to the more typical group of the Genus Hxmorrhagia. 



Aellopos tantalus. 



Since Mr. Walker and Dr. Clemens have confounded the present spe- 

 cies and Adlnpos titan together, we do not cite these Authors in the 

 synonymy of either species. We do not find that Authors, since Lin- 

 naeus and Fabrieius wrote, have identified Sphinx Ixion Linn., a name 

 to which Mr. Walker refers as a synonym to Mua^oglossa Tantalus 

 Walk. Linnaeus' descriptive phrase reads as follows, while the absence 

 of any reference to the superior abdominal white band prevents our 

 considering the probability of Cramer's .S'. titan being intended : " Ixion. 

 26. 8. abdomiue barbato: lateribus punctis utrincjue 4 niveis. M. L. 

 U. Habitat in calidis regionibus." Syst. Nat. p. 803. Fabrieius in 

 his '' Entomologia Systematica" refers S. Ixion as a synonym to S. 

 tantalm, citing Cramer's figure, Plate 68, fig. F, and doubtless without 

 autoptical knowledge of the species which now appears to be lost. 



Amphion nessus. 



Hiibner, in erecting this genus in his •' Verzeichniss," associates with 

 it, apparently erroneously, Cramer's 8. Brennus, Plate 398 (396), fig. 

 B (D), referred to the genus Cliserocampa by Mr. Walker. The Ame- 

 rican species is evidently regarded as the more typical of the genus by 

 Hubner, who enumerates it first. A. nessus is geuerically distinct frum 

 Thfjreus ahhotii, and it seems proper to retain Htibner's generic name 

 for the species. 



Hemeroplanes pseudothyreus. 



This species resembles S. oiclus Cramer, from Surinam, in the dis- 

 position of the prothoracic markings; otherwise it is very distinct from 

 both Cramer's figure and description. 'J he latter reads as follows: — 

 '• Ce Sphinx a sur le beau dessein de cha(|ue aile superieure, trois pe- 

 lites taches d'uu lustre argeute, dont I'une est placee vers les jointures,
