SYSTEMATIC TREATISE OF OHIO SPECIES 
Subfamily ORTHEZIINAE. 
Under this subfamily are included only three genera, viz.. 
Orthezia, Newsteadia and Ortheziola, neither of the last two 
named being represented in the United States. 
Genus ORTHEZIA Bose. 
Mr. C. P. Lounsbury, in his paper on Orthezia, published as 
a part of the 32nd Rep. of the Mass. Agricultural College (1894), 
eives the following generic characters for Orthezia: 
“Adult Male: Head, thorax and abdomen distinct. Eyes and 
ocelli present. Antennae long, filiform, nine-or ten-jointed. Wings, 
two, diaphanous with one furcate nerve. Halteres, each with a bristle 
which hooks into a pocket in the base of the wing. Legs long, 
pubescent, with one claw, no digitules. Two or more long, slender, 
snow-white filaments project from near the posterior end. 
Adult Female: Head, thorax and abdomen not separated. An- 
tennae eight-jointed; nine-jointed in maenariensis (Doug.). Tarsus 
with one claw without digitules. Eyes simple. Anal ring with six 
setae. Body more or less covered with cereous matter arranged in 
compact symmetricai plates. The eggs are laid in an elongated ovisac 
which projects behind the body, and are there carried until they hatch. 
The insect is active throughout its entire life.”
