the basal line, which is then continued across along costa to t. a. line 

 again, thus forming a brownish ring in the superior enclosed part of basal 

 space ; the centre of the ring shows as a spot soxnevvhat lighter in shade 

 than the general ground colour. The inferior part of the basal space is 

 also somewhat lighter than the ground colour. With the lens a few black 

 scales can be seen as an extension of the connecting line to the base, but 

 not enough in the specimen before me to be called a basal dash. The 

 median shade is black, heavier, and more prominent than the other lines, 

 especially at the costal end. It runs from the costa downward and out- 

 wards along inner border of reniform to its lower border, where it meets 

 the t. p. line and accompanies it to inner margin. The t. p. line is 

 thickened at its origin on costa, is exserted over cell, touches lower border 

 of reniform, thence by three inward scallops between veins to inner 

 margin ; the upper portion of line is only slightly scalloped. The t. a. 

 line i.5 nearer the base of the wing in this species than in occaia, so that 

 there is a wider space between it and the t. p. line on inner margin, and 

 the median shade does not tend to diffuse itself over this space as in 

 occata, but clings to the t. p. line as a well-defined band, only covering 

 from one-third to one-half the space. To the outer side of the t. p. line 

 is an accompanying brown shade line, which is more pronounced on 

 costa. The s. t. line is pale, and indicated chiefly by the contrast 

 between the terminal and subterminal spaces. It is irregular and not well 

 defined. The veins from the t. p. line outward are more or less coated 

 with black scales, and the spaces between them in the subterminal space 

 are somewhat dusted with brown scales, which in the lower three or four 

 spaces show a tendency to arrange themselves into rather poorly-defined 

 arrow heads, with the points in. Occata shows neat black dashes in those 

 spaces. There is a neat, even, black line at base of fringes which seem to 

 be concolorous with terminal space and not checkered as in occata^ but in 

 the specimen before me they are quite worn away, so that it is impossible 

 to give an accurate description of them. The orbicular is strikingly 

 different from that in occata ; it is almost or quite as large as the reniform, 

 oval, with long axis longitudinal, neatly outlined by a fine black line, 

 and of a bluish-gray colour, contrasting with the brown of the median 

 space. Closely within the black ring there is a narrow brown ring. The 

 reniform is upright, oval, concolorous and outlined by a fine black line, 

 which is a little irregular in its course, it is a little darker to the inner side, 

 seemingly due to the median shade encroaching on it. The claviform is
