8 . AMERICAN LEPIDOPTERA. 



and more distinct, below the latter on the dorsal margin is an indis- 

 tinct spot ; these spots are variable and may be obsolete. Cilia gray, 

 with some whitish scattered scales in basal portion. Hindwings rather 

 narrow, pointed, under 1, grayish with some lustre; cilia gray, nearly 

 2. Abdomen fuscous, segments fringed with whitish scales; anal 

 bush ochreous-fuscous. Legs grayish, fuscous externally, an oblique 

 band at middle externally and apices of tibiae pale ; tarsi fuscous, joints 

 pale at apex. 

 Expanse 12.0-18.0 mm., 0.41-0.72 inch. 



Hab. — Texas. 



Five specimens, three females and two males, in the Nat. 

 Mus. Coll. are before me. They bear the label " Bred from 

 Yucca baccata, iss. Apr. 18th, 1897." It is quite likely that 

 freshly bred material may have a decided darker color. 



4. B. plmmiierella n. sp. (Plate I, fig. 4.)— Head, palpi, basal 

 joint of antennae and thorax gray, dusted with fuscous, with some 

 metallic lustre; antennae fuscous, very faintly annulate with pale; 

 stouter, finely denticulate and ciliate beneath, cilia \, deeply excised 

 above basal joint in the male, simple and more slender in the 

 female, palpi slender, a trifle longer in the female than the male, 

 second joint dark fuscous externally and along the margins within, 

 third joint nearly as long as the second, thinly dusted with fuscous. 

 Forewings elongate, ground color grayish-white, clouded with dark 

 fuscous ; base dark fuscous becoming paler externally where it leaves 

 an ill-defined, strongly curved fascia, the summit of which reaches to 

 two-fifths and within the latter is the first discal spot, externally the 

 fascia is limited by dark fuscous marginal clouds beginning at one- 

 third, which more or less coalesce and become effaced externally, the 

 fuscous clouding is more pronounced in costal half of wing, two well- 

 marked spots at end cell, another ill-defined, but strongly curved 

 fascia in apical part of wing ; the fuscous dusting is interspersed with 

 whitish scales ; cilia grayish-fuscous, sparsely sprinkled with whitish 

 scales. Hindwings nearly 1, grayish-fuscous, darker externally and 

 along the dorsal margin ; cilia gray, a little over 1, paler towards the 

 base. Abdomen fuscous, anal bush ocherous ; legs grayish-white, 

 more or less thickly— especially externally— dusted with fuscous, tip 

 of tibiae and tarsal joints paler. Expense 10.0-14.0 mm., 0.4-0.56 inch. 



Hab. — Plummer's Island, Md. 



Six specimens, three males and three females, from the 

 Nat. Mus. Coll. are before me. Taken by Mr. A. Busck at 

 the above locality, July, 1903. Somewhat variable in extent 

 and definition of markings and even in wing form.
