The Tingitoidea or “Lace-Bugs'" of Ohio 
231 
very strongly bullate about the middle, slightly reflected at the posterior margins. 
Hood moderately raised, not very abruptly constricted about the middle. Median 
Carina with one complete series of areolae and two cells divided near the middle 
forming double cells. Pronotum regularly and coarsely punctured. Apex of tri¬ 
angular process reticulated; the sides feebly raised anteriorly, with two or three 
small areolae. Costal area with three complete and one partial series of areolae, 
very unevenly reticulated. Length, 4.1 mm.; width, 2 mm. 
Color: Body brown-black. Lateral portion of prothrax and terminal segment 
of abdomen ochraceous. Antennae yellowish; apical segment embrowned. Legs 
yellowish; tarsi slightly embrowned and usually darker at tips. Hood, mem¬ 
branous pronotal margins, and triangular process pallid. Elytra pallid, with an 
indistinct very light brownish band near the base. Length, 4 mm.; width, 2 mm. 
Five specimens, taken on linden at Sugar Grove (Dr. Kellicott), and 
at Columbus (Prof. Hine). 
Variety idniif We have numerous specimens taken on Ulnnis arneri- 
canum (Sanders) at Lisbon, Sept. 4th, 1903. They are slightly smaller 
and the transverse band near the base of the elytra is a little more dis¬ 
tinct. There are also a few more erect spines on the membranous prono¬ 
tal margins and elytra. The specimens seem to be slightly discolored 
and with the material in hand we do not feel warranted in separating it as 
a distinct species. 
Corythucha pruni spec. nov. 
Close to C. aesctila, but readily separated from it by the narrower and 
much less elevated hood, the shorter first segment of the antennae, and 
the slightly raised median carina at the middle. 
Antennae beset with numerous bristly hairs; first segment slightly more than 
twice the length of the second; fourth segment swollen on the distal half. 
Rostrum reaching the meso-metasternal groove. Hood, narrow, moderately ele¬ 
vated, rather widely reticulated, not very abruptly constricted about the middle; 
posterior portion subglobose; anterior portion triangular. Membranous pronotal 
margins very broad, evenly reticulated, bullate about the middle, slightly raised 
at the anterior and posterior margins. Pronotum and base of triangular process 
coarsely punctured, the sides of the latter feebly raised anteriorly with three or 
four areolae. Median carina foliaceous, not strongly elevated about* the middle. 
Elytra broadly rounded at the tip, the outer margin sinuate; costal area widely 
and unevenly reticulated; with three complete and a partial row of areolae. 
Length, 4.2 mm.; width, 2.3 mm. 
Color: Body black; apical abdominal segment fulvous. Antennae yellowish; 
the apical segment embrowned. Legs yellowish ; tarsi embrowned. Hood hyaline; 
the nervures, especially on dorsal surface, more or less embrowned and a few of 
the areolae somewhat clouded. Membranous pronotal margins hyaline, with one 
or two small spots near the outer margin brown. Pronotum yellowish. Elytra 
hyaline; a band near the anterior and one near the posterior margins, and more
