1922] Notes on Livia Maculipennis 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 Juncus which is 

 a plant belonging not to the "sedges" but to the ''rushes", 

 hence it might be called more correctly, the rush psyllid.

 speciesofOrthotylus 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
