74 W. J. HOLLAND. 



A l>ro!id, blackish, subapical shade extends from a little below the apex ou the 

 outer marjjin to the transverse posterior line at the point where it crosses 

 the third submedian nervule. A still broader and darker shade extends from 

 the base of the wing below the cell terminating upon the outer margin at the 

 second submedian nervule This shade is darkest on the intra-neural spaces; a 

 small curved dash of black appears near the costa and parallel to it just before 

 the apex. The nerves and uervules, esiiecially near their marginal extremities 

 are defined by black. Posterior wings uniformly dull gray with broad margins 

 (if a lighter shade, the nervules darker, especially toward their extremities. 



UNDERSIDE.--Light ashen gray, with the basal and middle area of the anterior 

 wings dnrker in color. Both wings have a dark shade crossing the end of the 

 cell and both are crossed by a dark transverse posterior line vanishing before the 

 inner margin is reached. Expanse of wings 62 mm. 



Type in coll. Holland. 



It is with some hesitation that I refer this fine species to the genus 

 Notodonta. The only specimen I have seen is the type, which is a 

 very fresh specimen taken at Yokohama, and another badly damaged 

 examj)le, likewise a female, in the collection of Mr. Pryer. The 

 apparent absence of the tooth-like projection of the wing upon the 

 inner margin of the primaries would indicate the propriety of refer- 

 ring to another genus, but, as this feature is less marked in the male 

 than in the female sex of other species, I have not been willing to 

 run the risk of creating a new genus for the reception of this insect, 

 as I have been urged to do by one or two of my scientific friends 

 who have examined the specimen. 



I name the species in honor of Prof David P. Todd, Director of 

 the Amherst College Observatory. 



NOCTUAE. 

 Genus RUSINA Boisd. 



6. Rusina Ripleyi n. sp. — % 9 . Front white, corselet and patagise dark 

 gray, bordered with white. Thorax and abdomen lustrous pearly gray. 



Upperside. — Anterior ivings with an irregular black spot at base bordered 

 externally with whitish, basal area dark gray, transverse anterior and jtosterior 

 lines irregulai', light grayish white, bordered on both sides by a narrow black 

 line. There is a light spot in the cell bordered with black and followed by a 

 dark transverse shade widest ou the costa and interrupted by the reniform. which 

 is black circled with light gray. The limbal area is darker gray than the middle 

 area and is traversed by three somewhat parallel and very narrow black lines, the 

 first two of which run obliquely from the direction of the costa toward the outer 

 margin, and the third, which is broken, terminates upon the inner margin before 

 the inner angle. Posterior wings light rufous gray, with the outer margins 

 broadly blackish. Fringes whitish, checkered with the dark shade of tiie 

 margin.
