angle, and thence along the base of the cilia to the tip ; it is margined 

 on the costa rather indistinctly by white. The dorsal cilia are whitish, 

 mixed with oclieroiis ; there is an oblique streak of dark brown in the 

 cilia behind tlie tip, and a few scattered scales of the same hue, above 

 the base of tlie costal cilia. Under surface and legs very pale ocher- 

 ous. Al. ex., 5-16ths inch. The larva feeds on the leaves of Ambrosia 

 trijida. 



B. quinquenotella (n. sp.) 



Face, and entire under surface of body and legs, silvery white, with a 

 faint, yellowish tinge, and the tar.^i dusted with brown on their anterior 

 surfaces ; antennie with alternate annulations of silvery white and black; 

 tuft silvery white, becoming brick red on top ; eye-caps silvery white ; 

 fore wings reddish orange or reddish ocherous, according to the light, and 

 sparsely flecked with brown. The basal part of the fore wings is much 

 lighter than the remainder, and the apical part is more distinctly yel- 

 lowish than the middle, which is darker. There are three silvery white 

 costal streaks : the first is placed at about the basal fourth, and extends 

 obliquely across the wing to the dorsal margin, just before the dorsal 

 tuft, but becomes near the dorsal margin somewhat suffused with 

 or even interrupted by yellowish scales ; the second is small, straight, 

 near the middle of the wing, and the third is placed just behind 

 the beginning of the cilia, is long and narrow, almost crossing the 

 wing to the dorsal cilia, where there is a dorsal, silvery white spot im- 

 mediately before it, at the beginning of the dorsal cilia. There is a 

 patch of blackish scales in the apex margined before by a silvery streak, 

 which does not reach either margin. The fringes are silver gray, with 

 a very distinct, dark brown hinder marginal line at their base. The 

 dorsal tuft is dark brown, and in perfectly fresh specimens there are a 

 few scales longer and darker than the others projecting from it. Al. ex., 

 one fourth inch, Kentucky. 



It seems to resemble Dr. Clemens, B. trifasciella, but can not be it if 

 Dr. Clemens has correctly described that species. 



B. pachirddla, Cham. — Can. Ent., vol. iv., p. 151. 



I have bred this species from cocoons found on the trunks of beech 

 trees. The description loe. cit. was made from two specimens taken at 

 the light, and on comparing them with bred specimens, I find that 

 they were a little singed. In the bred specimens the "small brown 

 dot on each side of the apex of the thorax " is absent, and the portions
