fuscous. 
Fla., Texas. Probably everywhere in East and South. 
The determination of this insect as above is I think the correct one. 
Zeller’s type was smaller than the type of dlucu/el/a, Grt., but the figure 
Zeller gives, and the type in the Cambridge Museum allow no other de- 
termination as it seems to me. ‘There is a great deal of variation in the 
depth of coloring in the species, and diducu/ella might stand as a varietal 
name for the form with the black basal field. The insect is 2-brooded 
in Texas and the varieties incline to be seasonal, d/uculedla being the 
larger and darker Summer brood. Za/leo/alis is a synonym of the type 
form. 
Prof. Comstock, in Dept. Agric. Report, 1880, gives a history of 
the insect as follows: 
** Larva.—Length when full grown 20 mm., cylindrical, slightly tapering 
posteriorly and quite stout, of a dull greenish yellow color, somewhat paler beneath, 
with a narrow black stripe on each side about twice the width of the last, and equally 
distant from it and the middle of the dorsum. This stripe extends from the thoracic 
to the anal plate. The head, thoracic and anal plates are of the same ground color 
as the body. Eyes and end of mandibles black ; several irregular black bands on 
each side of the head, extending from the posterior side forward to about the middle: 
thoracic and anal plates with a few scattered brown dots, the latter with an irregular 
row of black points across the anterior side. 
Pupa.—Length 11 mm., robust, light brown, rounded at both ends, the posterior 
armed with a cluster of fine hooks ; the abdominal segments are covered with coarse 
punctures except on the posterior edge. Wing covers extend to the end of the 4th 
abdominal segments.”’ 
‘*Some of the terminal twigs of pine (Pmus taeda) infested by the 
larvae of this insect where collected by myself in January, 1880, near 
Jacksonville, Fla. The appearance of these infested twigs is somewhat 
striking ; the leaves around the end are loosely held by threads of silk, 
which also holds the excrements of the larva in a move or less irregular 
mass, varying from 1 to 3 inches in length and from 1 to 2 in thickness. 
The larva is about eight-tenths of an inch in length, rather stout, of 
a greenish yellow or drab color, with two very distinct, quite broad 
black dorsal stripes, and a narrow one on each side. 
When mature the larva descends to the ground, where it spins a 
loose cocoon of yellowish brown silk, to which is attached a covering of 
grains of sand or other loose materials, and within which it transforms 
to a pupa, in which state it passes the winter. 
The moths from the larvae mentioned above emerged during the 
following April.” 
Taken in Texas in April and Aug. and consequently two-brooded.
