 cident with the Vtasal, starting! troni (inter third of costa and rcachinjj; outer f'oifrth

 nal and also faint, narrowinj;' toward anal anf;le and l)roa<lenin^- toward eosta ; all, 

 esiieeially 1, 2, and 3, are broadened and intensitied on eostal and inner borders; 

 friuf«e broad, ooncolorons, with nine more or less distinet dark spots alonj^ base in a 

 Hue with the veins. 



Secondaries. — Slightly paler in color, with four less distinct transverse dark bauds; 

 the iirst across basal fourth, the second across middle and involving discal spot, the 

 tliird more diftuse and between it aud the terminal and the fourth terminal; the 

 basal two darker and narrower than the others; all somewhat intensitied and broad- 

 ened on the inner border. Fringe marked with dark s]iots near base aud in line 

 with the veins. 



Under surface of the wings somewhat darker than upper surface, more uniform 

 in shade, with the pattern of the upjier surface more faintly discernible except the 

 discal spot, which is more intense. 



No esi)ecial sexual colorational difterences, the males being somewhat smaller and 

 having rather darker front legs. 



There is some v.ariation, not only in the general color Imt also in the distinctness 

 of the transverse lines. In some of the specimens there are a number of dusky 

 scales on the light background between the bands, nuiking these more diffuse ; in 

 others the bands are very abruptly and distinctly sei)arated from the ground color. 



Egg. — Bluntly ovoid, 0.04 millimetres in length, pale grayish and usually quite 

 delicate, but tirni enough to retain its shaxie after hatching, and irregularlj^ reticu- 

 late. 



FnU-groicn larva. — Seven millimetres in length, normal, and possessing but one 

 pair of abdominal ])rolegs, pale olive gray, Avith medial dorsal and subdorsal darker 

 lines; head honey-yellow inclining to brownish; antenna- paler and with a few 

 pale short fleshy bristles; the whole body is transversely wrinkled on the longer 

 and middle segments, showing from six to seven or more of these transverse folds. 

 In the dorsal region on each of the anterior and posterior folds are two spatulate 

 processes arising from rounded tubercles, while subdorsally and laterally there are 

 a series of about four to each segment and subventrally two of these same spatu- 

 late processes. On the aual segment these spatulate processes are more numerous 

 aud close together. 



Pupa. — The pupa is characterized chiefly by a lateral projection on the fifth 

 abdominal joint and by a somewhat brief cremaster with six rather long hooked 

 bristles.
