Notes on Livia M aculipennis 
229 
This is a smaller species, measuring but 0.10 to the tips of its 
wings, and is tawny red, with the thorax tinged more or less with 
dusky, the antennae with a broad black band towards their tips, 
the anterior wings more short and broad than in any of the other 
species, and hyaline with a broad smoky brown band on their 
tips, a spot back of the shoulder and some freckles near the margin 
also smoky brown, the veins, including the marginal, all white 
alternated with numerous black rings, the breast and hind breast 
blackish and the legs dusky brown tinged more or less with tawny 
yellow.” 
Miss Edith M. Patch has referred to this species several 
times and these references can be found in Van Duzee’s catalogue. 
In Pysche (vol. XIX, p. 6,1912) Miss Patch places Provancher’s 
Livia bifasciata as a synonym of maculipennis. 
This insect which has commonly been known as the sedge 
psyllid has for its most conspicuous host a J uncus which is 
a plant belonging not to the “sedges” but to the “rushes”, 
hence it might be called more correctly, the rush psyllid.

During the summers of 1920, 1921, 1922, I found a very agile 
species of Orthotylus abundant on the hollyhocks in the grounds 
of the University Observatory at Ann Arbor, Michigan. From 
June until late September, at least, adults and nymphs 
were numerous, occurring on the upper side of the leaves, 
and the plants showed plainly the effect of their work. At the 
time when I first collected this form, I was unable to identify 
it with any described species of the genus, but subsequently I

University, No. 214.
