LITERATURE. 
This species was first described by Palisot de Beauvois under the i 
name of Coreas lineolaris, in a work on insects collected in Africa I 
and America, published in parts, between the years 1805 and 1821 . i 
It was next described by Say as C apsus oblineatus, in 1881, in a 
paper entitled, “Descriptions of New Species of Heteropterous Hemip- 
tera of North America. Say notes the similarity of his species to.> 
that described by Beauvois, but nevertheless considers them distinct, j 
He records its occurrence at various points, from Pennsylvania tc 
Indiana and Missouri. 
The first important mention of it as an injurious insect, we owe 
to Dr. Harris, who in his “Treatise on Insects Injurious to Vegeta, 
tion” (1841), describes it as Phytocoris lineolaris, notes its injury tc 
various blooming plants and to the potato, gives a very good accoun 
of its habits, and makes some recommendations for its destruction! 
based, however, upon conjecture, and not upon experiment. 
He knew nothing of its life history beyond the fact that it occurred 
in April and also in October, and probably hibernated as an adult) 
He believed its abundance at certain seasons to be due to dr 
weather, and accounted for the effects of its puncture by supposinjl 
it to poison the plants attacked. 
In the Prairie Farmer for 1860, (p/ 808), and for May 2, 1861m 
this species is charged by Mr. B. D. Walsh with injuries to th,| 
apple, quince and pear. The second of these articles was illustrated. 
In the Second Report of Prof. Riley, as State Entomologist (: 
Missouri (1870), occurs the next important article upon this specieil 
Besides rehearsing the facts already published by Harris, lie reporlj 
it as seriously injurious to various fruit trees, and to cabbages, tip 
nips and other garden vegetables; mentions the place of oviposi 
tion, and gives an (inaccurate) descriptive note on the young. r.j 
assumes, with hesitation, that two generations occur during, til 
year. He also recommends some additional topical application! 
but not upon experimental grounds. 
In the “American Entomologist and Botanist” for September, 1871 
Prof. Riley reprints this article from his entomological report, add 
some important items respecting injuries to vegetation, and detail 
the results of some experiments made by a correspondent, for tJ 
destruction of the pest in orchards. 
In 1872, a valuable article was published by D. B. Wier, in t I 
Prairie Farmer for January 27 of that year. Mr. Wier s experien 
with this plant bug in his nursery was especially interesting, and 
gives a veiy full description of its injuries to fruit trees, together wi i 
some additional items relating to its life history. 
A brief account of the species appeared in 1879, in the entomo 
gical report made to the State Horticultural Society of Iowa, , 
Prof. Herbert Osborn, of the Iowa Agricultural College. This, no
