Warts small, several haired; hairs short and black on tubercles I to 

 III, white snbventrally, both secondary and from tubercles V and VI. 

 Dorsum thickly covered with black points. A diffuse yellow patch 

 below warts I and II and around III. Joint 12 slightly enlarged dor- 

 sally. A few long black hairs at the extremities. 



Cocoon. — Single, but firm and tough, composed of silk and bits of 

 wood bitten off, a considerable portion formed by the supporting wood. 



Pupa. — Brown, shining, gently tapering, the abdominal segments 

 punctured all over, the i)unctures extending back to the finely sha- 

 greened incisures; wing cases grooved and transversely wrinkled. 

 Cremaster short, subconic, with large longitudinal wrinkles. Upper 

 hook one; lower, three on each side, regularly spaced; all large, with

(ironnd color dark bluish ash gray, quite heavily powdered and with 

 a somewhat smoky snfiusion. Head and thorax without markings, 

 exce[)t for the usual lateral line. Primaries with all the markings 

 fairly well defined. Basal line geminate, smoky, sometimes extending 

 to the basal dash. Transverse anterior line geminate, outwardly obliciue, 

 and (piite even. It is usually a little better marked at the costa, but 

 is traceable clear across the wing in all the thirty-odd specimens before 

 me. The median shade is marked on the costa by a rather feeble oblique 

 line, which crosses the reniform and is continued below it parallel with 

 the transverse ])ostericr line to the internal margin. This shade, while 

 not distinct or prominent, is traceable in almost every specimen clear 

 across the wing. The transverse posterior line is geminate, the inner 

 line smoky and not well marked, the outer line black, lunulate, the 

 intervening space paler than the ground color. As a whole the line is 

 quite evenly bisinuate. The subterminal line is pale, very slightly 

 marked m most of the specimens, but (juite evident in some of the 

 darkest forms. It is sometimes entirely obsolete. There is a series of 

 black terminal dots at the base of the fringes, beyond which the latter 

 are cut with black. The basal streak is broad and thick, extending to 

 the outer i)ortion of the transverse anterior line, but very rarely beyond 

 it. There is a dagger mark opposite the cell which touches but rarely 

 crosses the transverse posterior line. A similar mark in the submedian 

 interspace usually crosses the transverse iiosterior line, and is much 

 heavier than the other, without becoming as prominent as in lobdiae.
