and both pair of wings. The body beneath and base of palpi 

 pure white. It is immaculate and of the size of Ventralis, but it 

 is nearer to the group of Fodinalis. Several specimens have been 

 seen by me. 



EURYCREON ElAUTALIS. n. S. 



(5 ? . This species has the clypeus prominent, embossed ; the 

 infra-clypeal plate exserted. The pattern is not unlike Rantalis, 

 but the hind wings are more transparent and the bands on fore- 

 wings angulated. Fore wings pale ochrey yellow. Anterior 

 line outwardly oblique, uneven, shaded before with fuscous. 

 Reniform indicated. Outer line uneven, angulated opposite the 

 cell, followed by a fuscous shading over sub-terminal space. The 

 s. t. line indicated and with a deep sub-median sinus. No ter- 

 minal line. Fringes whitish. Hind wings white, with a denticu- 

 late extra mesial line, outside of which the wing is washed with 

 ochrey. Fringes white. Head and thorax ochrey. Beneath 

 paler, the markings faintly refletced. Expanse 22 mil. 



I have examined a number of examples, some less distinctly 

 marked than others. 



NOTES ON SOME NORTH AMERICAN LEPIDOPTERA 



By a. G. Butler. 

 [Concluded from page 132.) 



In the present part of my paper I offer a few remarks on the 

 Noctuites forwarded to us by Mr. Edwards. 



With the Noctuites of North America I have hitherto had 

 very little to do ; but I wish to take advantage of the present 

 opportunity to call the attention of Lepidopterists in the New 

 World to the true af^nities of this tribe of Moths. 



A study of the ontogenetic development of the Noctuites 

 shows that they are in all probability descended from the Geome- 

 trites; that their ancesters were "loopers." It is therefore very 

 important in a classification of the genera of Noctuites to place 

 those genera in which the looper-like character is retained longest 

 {i. e., the typical semi-loopers) next to the Geometrites, and those 

 in which it is soonest lost at the opposite end of the series. I 

 cannot myself attempt to do this with the few species here 

 enumerated, more especially as I could only guess by analogy 

 what the larvae of some of them would be like, but there can be 

 no question that a study of the earliest larval stages (suggested 

 by Weissmann) will throw a flood of light upon the true affinities 

 of this somewhat perplexing group. 



It should also be borne in mind by breeders of Leipdoptera 

 that the adult larvae of the so-called BombycoidcB exhibit the 

 characters of Liparida, ArctiidcB and Notodontidce as well as those 

 of typical Noctuites (and that on that account I have distributed
