2. B. hulstella n. sp. (Plate I, fig. 2).— Palpi long, ascending, 

 slightly recurved, moderately thick, the terminal joint nearly the thick- 

 ness of the preceding one, gray, the second joint without densely, the 

 third less so, overlaid with fuscous, extreme apex of former pale. 

 Head gray, speckled with fuscous. Antennae dark fuscous brown, a 

 trifle paler beneath, basal joint sordid grayish-white, scarcely one-half 

 longer than wide, pecten of stiff hairs. Thorax gray, speckled with fus- 

 cous, more densely anteriorly, forewings moderately wide, ground color 

 rather densely overlaid with dark fuscous-brown so as almost to con- 

 ceal the former, but leaving a distinct whitish fascia at one-third, the 

 latter is nearly straight, equidistant from the base at both margins, and 

 slightly bisinuate externally, it is heavily shaded externally, especially 

 in dorsal portion, forming a large, triangular dorsal patch not sharply 

 defined externally ; at the end of the cell are two large, dark brown 

 spots ; the dark dusting is somewhat more condensed along the costal 

 margin ; cilia dark gray, sprinkled with whitish and fuscous scales. 

 Hindwings as wide as the forewings, costa not refuse, apex obtuse ; 

 gray, dusted with fuscous, especially along the margins. Abdomen 

 above brown, segments fringed with pale scales; underside of body 

 and legs grayish-white, dusted with brown, apices of tarsal joints paler. 



Expanse 15.0 mm., 0.6 inch. 



Hab. — Texas, exact locality not known. A female speci- 

 men in my collection, contained in the Hulst Collection, and 

 obtained from Prof. John B. Smith of Rutgers College. It 

 gives me pleasure to name this form after its illustrious 

 collector, the late Rev. George Hulst. 



3. B. yuccrecolellan. sp. (Plate I, fig. 3.) — Head dark ochreous; 

 obscurely flecked with some fuscous scales ; antennas rather robust in 

 the male, more slender in the female, fuscous brown, basal joint 

 ochreous. Palpi not slender, alike in both sexes, grayish-ocherous, 

 thickly dusted with dark brown scales, apex of the second and third 

 joint pale. Thorax ochreous-fuscous. Forewings elongate, pointed, 

 ground color grayish-ochreous, overlaid with bark-brown scales, the 

 latter intermixed especially in outer part of wing with pale scales, 

 basal space paler than remainder of wing, limited externally by an 

 irregularly curved line, a large subquadrate costal and a smaller dorsal 

 patch, a heavy dash in the fold, base dusted with fuscous, some 

 scatterd dark scales along the fold, the marginal spots are about equi- 

 distant from the base, remainder of wing more densely overlaid with 

 fuscous scales, especially along the costa, with a nebulous spot about 

 the middle, apical part of wing interspersed with whitish scales, which 

 give when examined with a fairly strong lense a "pepper-and-salt" 

 appearance ; two spots at end of cell, the lower one generally larger
