darker shade, faintly broken into segmentary furcate patches. A 

 broad dil'l'use, red substigniatal band, most distinct in the jmler form. 

 Warts nearly in line transversely, IV nearly obsolete, yellowish, a more 

 or less distinct yellowish patch covering warts I and II on joints G to 

 12. Hairs stiff and spiny, shari) pointed, with a few lon^', slender, 

 black ones at the extremities. The si)ines are pale with black tip, a 

 few black, and, in the darker forms, those on joints 3 to 5 are deep red 

 at the base. From warts I to III on joints (5 to 10 are small tufts of 

 dense, Unify, barbnled, conspicuous, white hairs, but variable, in some 

 examples being so few as to be not noticeable at once. 



Pupa. — Posterior abdominal segments, rapidly tapering; coarsely 

 roughened Avith irregular dark i)oints, the posterior margins of the 

 segments smooth, raised, hoop-like. Thorax finely wrinkled, but com- 

 paratively smooth. Cremaster a slight tapering prolongation, shal- 

 lowly furcate, granular at the apex, with two short, stout, thick, coni(!al 

 spurs, one above the other, at the apex of each furcation. Length, 

 17 mm.

Ground color a very pale gray, almost white. Head and thorax with- 

 out perceptible markings; but always more or less black powdered. 

 Primaries powdery, with the markings all traceable; but tending to 

 become strigate. Basal line geminate, powdery, marked on the costa 

 only. Transverse anterior line geminate, very poorly defined, with 

 very strong outcurves in the interspaces. The median line is marked 

 by an oblique shade from the costa to the center of the reniform. The 

 transverse posterior line is lunulate, strongly dentate ou the veins, 

 blackish, with whitish included shades, so that in some specimens the 

 line seems to be white or nearly so, when the black lunules are not so 

 well marked. There is a series of prominent black terminal dots. In 

 some specimens there is a feebly marked black basal streak; but this 

 is never comjilete, and is more usually wanting. There are no dagger 

 marks. The ordinary spots are very obscure and scarcely defined. 

 The orbicular is oval, ringed with black scales and of the ground color. 

 The reniform is moderate in size, dusky, incompletely outlined, but 

 marked with black spots. Secondaries white, in both sexes without 

 markings except a broken terminal line. Beneath white, powdery,
