lu my catalogue 1 had referred B. perangulaUs to B. domnosalis, 

 Walker, and suggested their identity with B. deceptalis, without recog- 

 nizing the fact that the differences were sexual. Mr. Jiutler afterwards 

 disputed my references to B. damnosaHs, and judging from Walker's des- 

 crij^tion he is correct. He also suggested the sexual relation ot'B.peran- 

 gtilaUs to B. deceptalis, and in this also he is right. In tbe British 

 Museum the specimens were mixed, and I must have taken as type 

 specimen of Walker's B. damnosalis one not entitled to rank as such. 

 I cau uot ex])laiu my error in any other way.

Ground color deep chestnut brown, varying to smoky or blackish in 

 the male. Head and thorax coucolorous Avith the ])aler shade of the 

 primaries; abdomen like secondaries. Primaries with the space beyond 

 the transverse posterior line bluish gray or violet in the female, very 

 feebly violet tinged only in the male. Transverse anterior line feebly 

 marked, single, outwardly oblique, with two outcurves, that below the 

 median vein best marked; often entirely obsolete in the male, more 

 rarely in the female. Transverse posterior line slender, pale, princi 

 pally defined by the ditterence in shade between the median and sub- 

 terminal spaces, its course upright, or nearly so as a whole, with a little 

 outward angulation over the median vein, and another in the sub 

 median interspace. Subterminal line pale, vague, broken, sinuate, 

 sometimes marked by dark preceding black dots, but more usually by 

 a vague indefinite shade. Apex more or less pale marked, below which 

 is an obli(iue darker shade more or less obvious, but never prominent 

 and sometimes entirely wanting. A series of small terminal dots which 

 are often wanting, or in the male not visible. Through the outer por- 

 tion of the median space it darkens somewhat to the transverse poste- 

 rior line, forming a sort of median shade-band. Ordiiuiry spots 

 indicated by black scales as usual. Secondaries fuscous gray brown
