speckled more or less intensely with ferruginous or brown. The pos- 
terior half is deeper, with olivaceous and brown shades, and with more 
or less of lilaceous. The hind wings are dull-yellowish, more or less 
shaded with reddish brown. The markings are withal so unique, as 
shown in the figure, that the species cannot well be confounded with 
any other. 
"During winter the time elapsing from hatching to maturity has 
averaged, in our vivaria, about seven weeks, but development will be 
much more rapid during summer. 
" Should the Urena ever be cultivated for its fiber, this its chief enemy 
will readily be destroyed by the same methods recommended against the 
Cotton Worm. 
11 DESCRIPTIVE. 
" Anomis erosa, Hub. — Egg. — Diameter 0.8 mm , circular, flat below ; the upper sur- 
face A-aries somewhat in convexity, in some being almost hemispherical, whilst with 
others it is quite flat, in general shape and size reminding one of the egg of Aletia 
xylina. Color, pale yellowish-green, almost of the same shade as tti6 lower side of the 
leaves. The number of ribs which run from the base toward the summit varies in 
different eggs from 31 to 38. Of these ribs from 11 to 13 reach to about one-fourth 
the distance above the base, 5 to 7 half way toward the summit, and 16 to 18 to near 
the summit. The space between these ribs is divided quite constantly by 12 low 
transverse ribs, which at the intersection with the radiating ribs form a small though 
quite sharp triangular point, which is especially conspicuous in the empty egg. The 
spaces between these ribs form shallow, squarish depressions, which are finely gran- 
ulated. The summit is almost smooth, surrounded with three series of small, round- 
ish cells, which become larger away from the center, and beyond these another series 
of three rows of larger cells of different shapes, though more or less squarish. 
"Larva (Plate II, Fig. 1). — First stage. — Length of the newly-hatched larva, 2 mm . 
Color very pale greenish-yellow along the dorsum, white and transparent toward the 
sides; head pale yellowish, without any markings; eyes black, tips of mandibles 
brown. Antennae short, 3-jointed ; first joint stout, very short and somewhat conical ; 
second joint longest, clavate, its tip obliquely truncate externally, bearing at inner 
and outer angles a stout spine, which is a little longer than the third joint; third 
joint shorter than second, cylindrical, with a small tubercle at tip, resembling a fourth 
joint, and provided at its tip with a fine hair; at the inner side of the third joint, at 
base of the apical tubercles, arises a stout spine which is almost as long as the joint 
itself. Piliferous warts, pale brownish, each bearing a long and slender pale hair. 
Legs rather long, white ; only two pairs of abdominal prolegs, situated on joints 8 
and 9. 
" Second stage. — The first molt takes place seven or eight days after hatching ; at 
this time the larva} differ from the newly-hatched specimens only in the somewhat 
larger size and slightly darker color. 
" Third stage. — In from six to seven days the second skin is cast, and with this molt 
appears the third pair of abdominal legs on joint 7. They are, however, extremely 
small and scarcely noticeable; they are not used in walking. The color now is a 
darker green, lighter toward the sides, and with a pair of rather indistinct whitish 
dorsal stripes. Head highly polished, pale, faintly greenish, with two pale, dusky 
oblique stripes. Cervical shield slightly dusky, with a darker posterior margin. 
Piliferous warts black, the hairs colorless. The abdominal legs are marked externally 
with a broad dusky stripe. 
"Fourth stage. — The third skin is cast six or 6even days after the second molt. The 
larva is now almost of the color of the leaves, and measures about 14 mni in length.
