broad, flat, whitish scales. Mesonotum densely clothed with scales,
a broad median stripe of brilliant bronzy-brown small scales, the sides
and antescutellar area with larger, yellowish-brown scales ; bristles
over the roots of the wing are yellow. Abdomen black, each seg-
ment with a basal band of white scales, narrowed medianly and some-
what widened at the sides; venter white scaled, the apices of the last
two or three segments with a median triangular black patch. Wing
scales brown to blackish-brown. Legs black; tips of femora pale;
tarsi all black.
Male Hypopygium. (Fig. 3, PI. XI.) Side-pieces nearly three
times as long as wide; apical lobe prominent, rounded apically, with
short, retrorse setae; basal lobe large, rounded at apex and bears num-
erous hairs, a single stout hooked spine with an attendant group of
smaller spines. Claspette with long stem; filament long, slightly ex-
panded in the middle. Mesosome long, cylindrical; widely open on
the ventral surface, closed on the dorsum and at the base. Lobes
of the ninth tergite long, narrow, and each bears five or six short,
stout spines.
Larva. (Fig. 6, Pl. XX.) Length 8-9 mm. Head distinctly
wider than long; antennae spined all over; tuft situated before the
middle. Dorsal head hairs single, stout; anteantennal tuft in twos
or threes. Abdomen stout; lateral hairs single on the first to sixth
segments ; other hairs minute. Eighth segment with a lateral comb
of 5-8 scales arranged in a row. Anal segment as wide as long,
ringed by the dorsal plate; dorsal brush consists of two long hairs
on each side; ventral brush well developed, confined by the plate.
The anal gills are long and gradually tapered. The air-tube is stout,
three times as long as wide; pecten evenly spaced, the last three teeth
larger and frequently somewhat detached, not reaching the middle of
the tube; tuft of two or three hairs situated just before the middle.
The distribution of this species is not well known because
all the records refer to at least two species+u,nctor’ and ab-
serrates. It is known to occur in the Eastern United States
south to New Jersey. Very little can b,e said of the habits
of this species. It is found breeding in the same types of locali-
ties as A. pz~ctor. As I have not been able to separate the fe-
males of this species from fwzctor the habits, of the adults of
either species cannot be stated with any certainty.
