The hairs on the bases of the bulbs and horns are simple, but a few of those towards 

 the tips are lengthened out and spinulose as in Alarodia slossonice. The dorsal 

 groove appears darker than the rest. During the stage, the horns in the second 

 example (Rosslyn, Va. , No. i) became all the same length, the short ones growing 

 out. Length, 2.9 to 5.1 mm. (Rosslyn, No. l); 3.2 to 4.4 mm. (Rosslyn, No. 2); 

 104.6 mm. (Rosslyn, No. 3); 3.8 to 5 mm. (Chain Bridge). 



Stage V. — F"lattened elliptical, the radiating horns forming a flat disk ; dorsal 

 groove narrow, edged by the round bulbs of the horns of joints 4 to 11, the horn of 

 joint 12 small. Horns nearly equal, those of joints 4 to 6 a little shorter, especially 

 in front, gradually becoming longer posteriorly. Green, especially the outer two 

 thirds of the horns, the body more whitish ; dorsal groove darker. Hairs more 

 numerous than before, all simple on the basal bulbs but of dififerent lengths, shorter 

 around the bases of the horns ; at the ends of the subdorsal horns many of the hairs 

 are lengthened and finely feathery spinulose beyond the base, forming a fringe that 

 fills up the space between the hoins, the whole composing a flat disk and touching 

 the leaf. Side horns all obscured. Skin setose-granular as before. The basal fork 

 of the subdorsal horns is small and obscure, dominated by the large, nearly spherical 

 bulb that corresponds to tubercle i. The green color is very like that of the leaf. 

 Length, 4.6 to 6.3 mm. (Rosslyn, No. 3) ; 5 to 5.2 mm. (Chain Bridge) ; 5.1 to 7 

 mm. (Rosslyn, No. i). 



Stage VI. ^ Shape and appearance the same. The dorsal groove is very narrow, 

 the forked bases of the subdorsal horns almost touching, the two rows of nine bulbs 

 separated by about their own width, except those of joints 4 and 12, which touch. 

 Horns of joints 4 to 12 moderately long, horizontal, alike, the anterior ones only a 

 little shorter. Whitish green, the distal part of the horns brighter green. Hairs on 

 the bulbs all simple with enlarged bases, numerous ; terminal primitive seta of the 

 long horn simple, all the fringe-hair finely barbuled beyond the base ; many of the 

 short hairs on the dorsal aspect of the horn have the distal half densely feathered. 

 Head round, green, about .8 mm. wide. Skin granules small, remote, bearing rather 

 long pale setae Length, 5.2 to 7.5 mm. (Chain Bridge) ; 6.3 to 8.2 mm. (Rosslyn, 

 No. 3) ; 7 to 9.5 mm. (Rosslyn, No. i). 



Stage VII. — As before. All bright green, shining under the hairs, so as to be 

 a pale, glassy color, only the very tips of the long horns yellowish green. Horns 

 flat, spreading longitudinally, the whole larva very flat, its dorsal groove narrow and 

 edged by the circular knobs as before. Anterior pair of subdorsal horns (joint 4) 

 rather shorter and a litt'e curved backward ; the last pair (joint 12) also rather 

 shorter. Hairs fine, white, rather long, crossing from the adjacent horns and fringing 

 the larva all around. Most of the marginal hairs are long and spinulose, some of 

 those on the dorsal aspect and now also around the edges of the knobs. Hairs 

 nearly all of the feathered type, at least in part. Nearly all are'partly reduced in 

 length, the tip being slender and weak, the shaft a little thickened centrally with a 

 black band before the thickening. Even the fringe hairs are so and especially those 

 on the edges of the bulbs. All the hairs seem to be essentially so modified, though 

 those on the tops of the bulbs are still primitive, but they are black banded, and 

 grade off into the ones on the sides. Dorsal furcate roots of the horns long and 

 slender, touching sideways in pairs and joining across the dorsum, nearly smooth at 

 base, the small area of skin left, sparsely granular. Seta i on a long clear conical
