but usually dctined by a distiiict dark preeediug- shade which some- 

 times becomes diffuse, iiivohini;' the terminal space in whole or in 

 part, and occasionally reduces the line to a series of pale dotlets, all 

 intermediate forms occurrinii'. A series of blackish terminal lunules, 

 sometimes reduced to mere points. Median shade broad, diffuse, upright, 

 varying from this to entire absence. Orbicular small, rounded, varying 

 from yellow to concolorous, to black. Ileniform ui)right, narrow, paler 

 or concolorous, defined by l)lack scales, immaculate, with black points 

 Avhicli may be connected and form a lunule, or the entire spot may be 

 black and C(Uitrasting, in such cases somewhat undefined. Seconda- 

 ries smoky, varying- to fusccms or purply, with a dark median line fol- 

 lowed by a i)aler shade, and a pale sul)terminal line i)receded by a 

 dusky shade; in each instance varying to obsolescence. Beneath, 

 varying from gray to smoky or brown, powdery, with a variably marked 

 median dark and subterminal pale line.

Of the specimens before me no two are alike, and I know the range of 

 variation is greater than even my material indicates. In the line of 

 discoloration the tendency seems to be toward a pale basal and sub- 

 terminal space; but it may be reversed in a larger series. The most 

 couspicuous change occurs in the ordinary spots from yellow to black, 

 and I am not at all surprised that INIr. Grote made two species from 

 limited material. I have not seen his type, but have seen the speci- 

 mens named B. alutalis m his collection, which do not agree closely 

 with his description. From the description, which is quite character- 

 istic, I have named specimens fully agreeing with it, and certainly 

 referable to R. plenUinealis^ of which I have seen the type. 



The sexual difference between the palpi is marked in this species; 

 those of the male being oblique and somewhat shorter, while those of 

 the female are longer and straight.
