98 Notes on North American Lepidqptera. 



line; the terminal space is brown having the apical portion suffused with 

 whitish; the posterior wings are brown, thickly sprinkled with black 

 atoms ; the usual discal dot is present as well as a broad undulate median 

 line. 



Habitat. Brookline, Mass., Oct. 10. 



From the collection of the late Dr. C. A. Shurtleff, now 

 in the possession of the Boston Society of Natural History. 



The style of marking in this species is very unique ; it 

 can at once be distinguished by the brown ground color and 

 the two distinct, concave, white parallel cross lines inwardly 

 suffused, outwardly clear and contrasting. 



Plusia laticlavia, nov. sp. 



Expanse 32 mm . Length of body 16 mm . Habitus and markings of P. 

 precationis, Guen., to which it is closely related. Ground color lighter 

 than in the allied species, aurichalceous shaded with delicate pink as in P. 

 purpurigera, Walk. 



The reniform spot, the usual metallic spots and the general pattern of 

 the markings as in precationis ; it differs in the course and distinctness 

 of the median lines, the interior line being oblique, perfectly straight, 

 broad, and golden from the inner margin to the median nervure, and the 

 exterior line even, simple undulate and strongly contrasting ; above pur- 

 ple, near the inner margin becoming golden. Posterior wings dark gray. 

 Beneath suffused with yellow, lighter than in precationis. 



Habitat. New York. July 10, 1872. 

 Described from a single specimen in good condition re- 

 ceived from Mr. Fred. Tepper. 



Plusia formosa, Grote. 



(Leptina formosa, Grote, Proc. Ent. Soc. Phil. Vol. IV, p. 323). 



The description of " Leptina formosa" has always been of 

 great interest to us, for evidently the species intended was 

 not a true Leptina ; but its rarity has prevented us from de- 

 ciding its proper place. A careful examination of the single 

 specimen in the collection of the Boston Society of Natural 

 History convinces us that it is a Plusia, rather remotely al- 

 lied to P. ampla, Walk.
