patagia, crossed by alternate pale and dark bands, the contrasts varying. 

 Abdominal rings narrowly dark banded. Primaries, basal line single, 

 black, accompanied by a pale shade line, extends obliquely inward across 

 the costn] a^ea. T. a. line broken near the centre, dislocated, forming 

 rather a band than a line, and this band may be black or brown, or brown 

 with black margins. The median line is black, narrow, a little irregular 

 and somewhat curved, and this usually marks the division between the 

 paler basal third of the wing and the darker outer half of the median space. 

 T. p. line single, bl.ick, irregular, well and somewhat acutely curved over 

 the cell, reaching the inner margin a little beyond the middle. S. t. line 

 pale, irregular, forming a somewhat well-defined jog below the apex, 

 preceded by dusky or black shadings. A lunate or almost scalloped 

 terminal black line followed by pale or yellowish venular marks and a 

 dusky interline on the paler fringes. The orbicular is a black point, 

 which may or may not be obvious. The reniform is an irregular, nearly 

 upright, black line, beyond which is a diffuse whitish or pale shading. 

 Secondaries with basal two-thirds of a somewhat paler ground than 

 primaries, crossed by more or less obvious brown or blackish lines to a 

 distjnct narrow black line, which borders a dusky band that is outwardly 

 limited by the black, pale bordered s. t. line. Terminal line and fringes 

 as in primaries. Beneath an even, dull, deep smoky-brown, with a com- 

 mon darker extra median line, within which are three less obvious similar 

 lines, and a discal spot on all wings.

A series of over 50 examples is before me at present, and I have had 

 nearly as many more for comparison, all from the same general faunal 

 region. No two examples are entirely alike, and the above description 

 applies to a form in which all the normal markings are well defined. In 

 the actual course of the lines there is little real variation; but in the 

 amount of contrast between the spaces there is much. The basal and 

 terminal spaces may be bluish-powdered ; the outer half of the median 

 space may be contrastingly, dark, or it may be scarcely shaded ; the 

 whitish shade beyond reniform may be scarcely noticeable, or it may 

 extend to the costa and form a large quadrate blotch. As a general thing 

 the males are the smaller, although the largest males exceed the smaller 

 females.
