DISTRIBUTION—Illinois to Virginia, south to Florida, March to June.
FLOWER RECORDS — Batodendron, Malus, Prunus, Pyracantha, Rubus, Taraxacum and Vaccinium. This is recorded by Robertson (1929) on Antennaria, Arabic, Cercis, Dentaria, Erythronium, Geranium, Ribes, Salix, Stellaria, Taenidia and Zanthoxylum.
The form described above is that which has come to be accepted as Olivier’s luteola, but it is not certain that it is correct. The description is too brief, and the type specimen has not been located. It seems best to continue using this name, however, until it has been shown to be erroneous.

Female.—Head blackish-brown; sides of the face, clypeus, a spot
above it, labrum, mandibles except tips, and a small spot in front of
the ocelli, yellow ; a blackish-brown line extends half-way down the
sides of the clypeus. AntenujB as long as the head and thorax, dark
fuscous towards the apex, rufous or dark ferruginous at the base, the
scape in front is sometimes yellowish. Thorax densely punctured,
blackish-brown ; the collar, tubercles except a blackish indentation in
front, two longitudinal lines on the disk not reaching either the collar
or scutellum, a line over the base of each wing reaching from the collar
to the angles of the scutellum, the tegulne except a blackish spot
on the disk, the scutellum which is subbilobate and rather prominent,
a transverse line on the postscutellum, a large quadrate patch on each
side of the metathorax, a small spot beneath the base of the wings
connected with a large quadrate patch beneath, and two spots in front
of the intermediate coxae, yellow. Wings fusco-hyaline, apical margins
clouded, with a pale lunula near the tip ; stigma pale ferruginous, nervures
ferruginous. Legs yellow varied with ferruginous, especially
the femora at base and within. Abdomen blackish-brown, each segment
above with a broad yellow fascia, the posterior margin of which
is slightly attenuated and more or less waved, the anterior margin of
the fascia on the first segment is slightly denticulated ; beneath same
as above, except that there is a spot, instead of a band, on the first
segment, and the fascije are rather more attenuated iu the middle posteriorly.
Length 6 lines.
Male.—Head black ; clypeus. a spot above it, labrum, mandibles
except tips, face on each side of the clypeus, and the orbits of the eyes.
yellow ; a minute black dot on each side of the clypeus. Antennte
rather long, ferruginous, blackish behind towards the base ; scape robust,
yellow in front, black behind. Thorax black, clothed with short
pale hairs ; the tubercles, an oblong spot beneath, the tegulae except a
spot on the disk, two small round spots on the scutellum, and (in one
specimen) a small bilobed patch on each side of the metathorax, yellow.
Wings hyaline, apical margins faintly clouded. Legs yellow ;
base of all the femora, the posterior femora and their tibiae within,
and a more or less distinct oblong spot or vitta on the outside of the
posterior tibiae, blackish or fuscous. Abdomen black, with yellow
fasciae similar to those of the female, that on the first segment above,
being sometimes interrupted in the middle. Length 5 lines.
Hdh. Penn.. Del, Conn. (Coll. Ent. Soc. Phil., and Mr. E. Norton.)
The longitudinal lines on the thorax are sometimes ferruginous or
yellow margined with ferruginous.
I have before me four $ specimens which have the face rather
shorter, the clypeus, labrum and mandibles, except tips, either entirely
ferruginous or yellow stained with ferruginous, and a small
black dot on each side of the clypeus ; except in one specimen, there
is no yellow spot in front of the ocelli ; the longitudinal dorsal yellow
or ferruginous lines of the thorax and the yellow patch on the pleura
are sometimes very indistinct or entirely absent ; the sublobes of the
scutellum are smaller and more prominent and the yellow transverse
line on the postscutellum is reduced to a mere spot ; the yellow fascia
on the first segment of the abdomen above is deeply indented on the
middle anteriorly, and sometimes interrupted with ferruginous. These
four specimens are more slender in form than the three females from
which the main description was taken.
I have another 9 variety from New Jersey, which has the longitudinal
lines of the thorax bright ferruginous; the spots on each side of
the metathorax are triangular and become confluent on the disk, and
the legs are almost entirely ferruginous ; this specimen is more robust
than the females above described.
Also another 9 variety, probably of this species, from Pike's Peak,
which is ferruginous, with the sides of the face, the collar, tubercles,
tegulae, a quadrate patch on the pleura, a large quadrate spot on the
scutellum, a transverse line below it on the postscutellum, a small spot
on each side of the metathorax near the insertion of the abdomen, part
of the coxae and the usual fasciae on the abdomen, yellow; there is no
appearance of longitudinal lines on the thorax, and the scutellum is
flat, not subbilobate ; the legs and antennae are entirely ferruginous.
It may be a distinct species. In this specimen, the right wing has the
third submarginal cell petiolated. as mentioned before on page 281.
