into rings inclosing whitish spaces. Four straw^yellow dorsal bands, varying from whitish 
to straw-yellow, and inclosing three narrow, broken chocolate lines. Below the broad lateral 
chocolate band are two whitish yellow irregular lines, one just above and the other Just beneath 
the spiracles. Underside of the body with the abdominal legs x)ale livid-gray. On the outside 
of the abdominal legs above the planta is a dark chocolate-brown patch. Suranal plate dark 
chocolate brown. The hairs are sparse and pale gra}', uneven in length; the few longest ones 
arise from the thoracic segments and from the eighth to ninth abdominal segments. The piliferous 
warts are yellow on the yellow ground and brown on the brown portions of the skin. On the 
eighth abdominal segment are two yellow piliferous tubercles situated on the brown skin. 
It molted June 22, 
It seems to be like the Eastern apicalis (van) in Stage III. 
Stage III. — Length, 15 mm. Head chitinous brown, mottled with close set dark spots. 
Prothoracic shield divided into two parts by a pale median space. In general as in Stage II, 
but the four pale dorsal lines are whiter than before^ becoming straw-yellow around the bases 
of the yellow i)iliferous warts. The brown lines and lateral band and the brown swollen first and 
eighth abdominal segments are as before. Hairs long whitish. On the brown bands and segments 
the piliferous warts are pale, not prominent. 
The larvae have now sewed together two leaves and live between them much as does 
J. incliisa. 
The larvm molted into the last stage June 28 to July 12. 
'The larva when of this stage is more like J. inclusa when about 15 mm. long than the fully 
grown Eastern apicalis (van), though in I. inclusa the eighth abdominal segment is not brown, 
according to Bridghands figure, and is somewhat as is albosigma in its thii*d stage. 
Last stage. — Length, 30 mm. Body thick and full. Head not so wide as the body by a fifth; 
pale yellowish brown or chitin colored, with darker fecks; it is much fattened in front, the 
clypeus flat and sunken. Jaws and ocelli blackish, contrasting with the light-colored head. 
Body of a peculiar light yellowish sienna-brown, with a grayish tinge. Skin somewhat rough, 
with fine minute warts giving rise to fine close-set pale gray hairs of unequal length. On the 
prothoracic segment are two dusky dorsal flattened low warts elongated transversely, the 
corresponding ones on the succeeding segments being bright y^ellowish brown, each giving rise to 
one or two long thick pale hairs. A lateral yellowish brown wart in front of the prothoracic 
spiracles. On the second thoracic segment are three yellowish brown warts on each side, forming 
a transversely straight line of six warts crossing the segment. On the third thoracic segment is 
a transverse row of eight similar warts, the additional ones being one Just above the base of 
each leg of the third pair; corresponding warts are present on the jn-othoracic segment. No 
trace of a hump or of any other distinctive marie on the first or eighth abdominal segments^ hut in 
place of them are two small yellowish brown tcarts^ situated just in front of the Hue of siw warts 
common to all the abdominal segments^ though there are two similar but much smaller, nearly 
obsolete, warts which occur in the same ]»osition as on the other abdominal segments, those on 
the second abdominal segment being the most distinct. Three faint broken parallel dorsal lines 
and a faint lateral spiraciilar baud, above and below which is a faint whitish line. The skin is 
covered with somewhat irregular confluent colorless spots of irregular shape. All the legs are of 
the same color as the body. 
It pupated between the leaves July 12.

The single type differs from Mr. Edwards’s type of brucei in the oblique silver-white costal 
^streak being more sinuous, as is also the line across the wing which forms the continuation of the 
streak. On the other hand, the other (inner) arm of the V is straight, not sinuous, the inner two 
lines about the same. The submargiual spots and streaks are the same in both species.
