Var. fusco-purpurella. 



Two specimens taken with the above are decidely dark 

 fuscous brown, sprinkled with whitish scales, the latter more 

 profuse in basal two-fifths, this space is acutely angulated 

 outwardly, the apex of the angle extending beyond the mid- 

 dle of wing length. The wings are somewhat broader than 

 in the typical form, and it may prove to be distinct. 



Var. siiuplicella. 



A female specimen in my collection from Iowa City, ex- 

 pansion 16.0 mm., 0.64 inch, differs from the above by the 

 second palpal joint being pale at apex, head and basal joint 

 of antennae ochreous-gray, thorax grayish-fuscous. Fore- 

 wings gray, without markings, except a dark fuscous patch 

 at base of costa and two large spots at end of cell. It will 

 probably prove distinct. 



5. B. sagitella n. sp. (Plate I, fig. 5.)— Head gray, finely speckled 

 with fuscous, without lustre ; antennae slender, fuscous, very indis- 

 tinctly annulate with pale, finely denticulate beneath, basal joint gray. 

 Palpi moderate (cf) gray, thinly dusted with fuscous, lower margin 

 and a narrow ring before the extreme apex of second joint dark fus- 

 cous, extreme apex pale, third joint conical, two-thirds the length of 

 second. Forewings moderately wide, gray, speckled with dark brown ; 

 a pale fascia at one-third, a little nearer the base on the costal margin 

 and acutely projecting into the median space above the fold, outwardly 

 the fascia is heavily margined with dark fuscous brown, basal portions 

 of wing rather densely covered with dark fuscous scales at the base and 

 along both margins, a fine dark line immediately below the fold ; outer 

 part of wing more densely fuscous in costal portion ; two well marked 

 spots at end of cell ; about six or seven well marked marginal spots 

 around the apex, those on the costa more distinct. Cilia gray, dusted 

 with fuscous scales, especially in basal portion. Hindwings a trifle 

 under 1, grayish-fuscous, rather obtusely pointed, cilia grayish-fus- 

 cous, especially towards the apex, with pale basal line. Thorax and 

 abdomen dark fuscous, anal bush ochreous-gray. Legs grayish-fus- 

 cous, tarsi darker. Expanse 11.0 mm., 0.44 inch.
