Whether it feeds mainly on grasses or attacks also the various plants 
growing with grasses I can not at present say, as it has not been studied 
in such connection as to determine this point. 
It is about an eighth of an inch in length and of a yellowish-brown 
color with scarcely any decided markivgs except two black points on 
the front margin of the head and two similar points at the hind margin 
of the prothorax. These latter points are nearly in line with those on 
the head, though a little farther apart, so that the four points stand 
nearly at the corners of animaginary square. Other points within the 
square are in some specimens quite distinct, but not so conspicuous as 
the ones described. The species appears to have been first described 
by M. Provancher (Nat. Can., [V, 376), in 1872, but it has quite gen- 
erally been known among entomologists as Agallia flaccida Uhl. Mr. 
KE. P. Van Duzee (Entom. Amer., V., p. 167) says: 
This species I have received in exchange from a number of correspondents as 
Agallia flaccida Uhler, and have so used the name myself in exchanging and in the 
List of Muskota Hemiptera. It seems to have been an early manuscript name of Mr. 
Uhler. 
But little can be stated regarding the life history of this species and 
there are probably no important differences between this and other spe- 
cies of the same family. Nearly all the specimens taken or observed 
have been mature, and without rearing it would be uncertain whether 
larve apparently of this species really belonged to it. Adults have 
been taken at different times of the year, and probably it can be found 
in this condition during each month of the year. Mr. Van Duzee says 
in the article quoted above that ‘‘ this is a very abundant species in 
western New York from early in May until September, and in fact the 
year round, as it appears to hibernate in the adult state, as do many 
if not all the Jassid@.” ; : 
I have not found it in grass during winter, and can not say whether 
it hibernates mainly in pastures and meadows or seeks the shelter of 
dead leaves and rubbish in thickets, hedges, ete. 
Agalltia sanguinolenta Prov. 
This little Leaf-hopper has been quite common in this locality during 
the last few years, and while never so abundant that it can be counted 
a serious pest in itself it must be counted in with related species in any 
enumeration which pretends to give the grass-feeding species. That it 
has a wide range is indicated by the following from Professor Uhler 
(Bull. U.S. Geol. and Geog. Surv., vol. I, p.359[93, of part], 1876): “This 
is a very variable little insect, which is not confined to the region of 
the Rocky Mountains, but which has been found likewise in Texas, in 
British Columbia, Canada, and New England.” 
It was described under the name of Bythoscopus sanguinolentus by M. 
Provancher in 1872 (Naturaliste Canadien, [V, 376) and in 1876 by Pro- 
fessor Uhler under the name of Bythoscopus siccifolius. Mr. BE, P.Van
