227 
Color: Antennae yellowish; apical segment sometimes brownish. Legs 
brownish; tips of tarsi brownish. Hood and membranous pronotal margins hyaline, 
the nervures yellowish with parts more or less embrowned. Pronotum yellowish. 
Elytra hyaline, with a transverse band on the costal area near the base, a spot 
on the tumid elevation, and more or less of a band on apical third brown. 
A common species found on walnut and (sometimes) basswood. 
Malta (Drake), Jef¥erson (Sim), Columbus (Hine). 
Corythucha celtidis nov. sp. 
This species is very close to C. juglandis Fitch, but differs from the 
specimens that we have assigned to that species by the less elevated 
hood, the more numerous bristly hairs on the antennae, and the some¬ 
what different markings at the tip of the elytra. 
Antennae slender, beset with numerous, moderately long bristly hairs; first 
segment twice as long as the second; fourth segment swollen towards the apex. 
Rostral groove quite wide; rostrum reaching the meso-metasternal suture. Hood 
moderately raised, abruptly constricted about the middle; posterior portion globose, 
rather evenly reticulated; anterior portion triangular, more closely reticulated. 
Membranous pronotal margins broad, kidney-shaped, bullate about the middle, 
slightly raised at the anterior and posterior margins. Pronotum and base of 
triangular process coarsely and regularly punctured, the latter reticulated at the 
apex; sides of triangular process feebly raised anteriorly, with a few distinct 
areolae. Median carinae foliaceous, with a double row of areolae at the middle; 
costal area unevenly reticulated, with thrjse complete rows of areolae. Length, 
3.6 mm.; width, 1.8 mm. ’ * 
Color: General color hyaline. Body above and beneath black. Legs yellow¬ 
ish; tips of tarsi embrowned. Antennae yellowish; terminal segment fuscous. 
Hood, membranous pronotal margins, and apex of triangular process hyaline, 
except nervures around two or three areolae brown. Pronotum and base of tri¬ 
angular process brownish. Elytra hyaline, a small vitta near anterior margin, 
posterior portion of tumid elevation, and more or less of a narrow indistinct band 
on distal third fuscous. 
Described from a long series of specimens, taken on hackberry in the 
various stages of development at Columbus during Sept., 1903, by the 
senior author. We have two specimens taken by Mr. Kostir at Cedar 
Point.
