Whether it feeds mainly on grasses or attacks also the various plants 

 growing with grasses I cau not at present say, as it has not been studied 

 in such connection as to determiue this point. 



it is about an eighth of an inch in length and of a yellowish-brown 

 color with scarcely any decided markings 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 an imaginary 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., IV, 376), in 1872, but it has quite gen- 

 erally beeu known among entomologists as Agallia flaccida Uhl. Mr. 

 E. P. Yan Duzee (Entom. Amer., Y., 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 

 larvre 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. Yan 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 Jassidce." 



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, etc. 



AgalUa 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. II, 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 Englaud." 



It was described under the name of Bythoscopns sanguinolenttis by M. 

 Provancher in 1872 (Naturaliste Cauadien, I Y, 376) aud in 1876 by Pro- 

 fessor Uhler under the name of Bythoscopus siccifolius, Mr. E. P. Yan
