Family Tingitidae. 
Head sometimes with dorsal porrect spines; juga not prominent, not 
longer than tylus. Antennae consisting of four segments; third segment 
longest. Rostral sulcus rather deep, sides raised; rostrum consisting 
of four segments. Ocelli wanting. Tarsi consisting of two segments. 
Pronotum, in front, with a hood or only tumid; lateral margins folia- 
ceous, reticulately projecting or closely lapped over on the pronotum; 
disc with one or three carinae; posterior triangular process usually long. 
Elytra of a uniform thickness, more or less closely reticulated thruout; 
membranous between the reticulations. 
This family contains several genera that present wide differences. 
KEY TO THE GENERA OF OHIO TINGITIDAE. 
1. Membranous pronotal margins not expanded; or reflected vertically; or 
reflected more or less against the dorsal surface of the pronotum. 8 
Membranous pronotal margins more or less reflected, but at an obtuse 
angle . 2 
8. Pronotum with a pronotal and discal hood, the latter divided behind; 
areolae very large.Genus Galeatus Curtis 
Pronotum with only a pronotal hood; areolae very much smaller. 3 
3. Rostral sulcus interrupted between the meso- and metasternum by a 
prominent, simiose, transverse carina.Genus Gargaphia Stal 
Rostral sulcus uninterrupted by a transverse carina. 4 
4. Outer edge of membranous pronotal margins and elytra, except distal 
third, armed with short, acute spines; elytra with a tumid elevation 
near the antero-inner margin.Genus Corythucha Stal 
Outer edge of membranous pronotal margins and elytra unarmed (in the 
genus Leptobyrsa closely beset with fine hairs). 5 
5. Pronotum with a single median carina.Genus Fenestrella n. gen. 
Pronotum tricarinate . 6 
G. Discoidal area reaching beyond the middle of the elytra. 
Genus Acalypta Westwood 
Discoidal area not reaching the middle of the elytra. 7 
7. Elytra very broad, extending about one-half beyond the apex of the abdo¬ 
men, the outer margin broadly rounded and beset with numerous, fine 
hairs.Genus Leptobyrsa Stal
