Habitat. — Colorado Territory, Mr. James Ridings. (Coll. Ent. Soc. 

 Phil.) 

 Anthoecia brevis, nov. sp. (Plate 6, fig. 4.) 



Thorax robust; wings short; abdomen slender. Anterior wings dark 

 olivaceous, shaded with dark brown in basal and sub-terminal spaces, 

 ochraceous in median and terminal ; median lines whitish, distinct. 

 Basal half-line obsolete; transverse anterior line forming three outward 

 curves, of which the costal one is a simple tooth ; median space ochra- 

 ceous, shaded with ohvaceous; median shade undulate, distinct, bor- 

 dering the darker ill-defined reniform spot; transverse posterior line 

 regularly sinuate, as in the other species of the genus, spreading a little 

 on the veins in the sub-terminal space, which are afterwards marked 

 with blackish. Sub-terminal space wide, constricted shortly below the 

 costa and again more slightly above internal angle, owing to the course 

 of the sub-terminal line which is indistinct but somewhat darker than 

 the s. t. space which it margins outwardly; terminal space narrow, some- 

 what darker than median ; fringes dark ochraceous, broadly and dis- 

 tinctly interrupted with dark olivaceous. Posterior wings black, with 

 a sub-basal macular band of three small dark yellow spots, the one on 

 the costa extending along the same to base ; fringes whitish, their base 

 yellowish, internal margin lined with yellow hairs. Under surface of 

 anterior wings yellowish ; a large black basal spot and a broad sub-ter- 

 minal black band, leaving the terminal margin entirely yellowish and 

 absorbing the discal spot; costa reddish. Posterior wings largely 

 marked with reddish along the costa, which shade tinges superiorly a 

 sub-median line which is blackish at and above anal angle, where it is 

 absorbed by the wide blackish terminal demi-band which it borders 

 internally ; discal spot blackish tinged with reddish, base blackish in- 

 feriorly. Thorax and head dark ochraceous, shaded with bright ferru- 

 ginous; abdomen blackish on the segments above, beneath reddish ochra- 

 ceous, as are also the legs and under surface of thorax. % S . Exp. 1 inch. 



A 9 specimen (Plate 6. fig. 5), differs by the pale more ochraceous 

 thorax ; the abdomen is blackish above and below except on the anal 

 seo-ment. the under surface is almost entirely blackish while the upper
