Duzee has, however, iii theEntomologica Americana (Y., 166) placed 

 this latter as a synonym, and remarks : 



Through, the kindness of M. Provancher I had the pleasure of examining a typical 

 example of his species and have thus been able to compare it directly with Mr. 

 Uhler's description, and find that it agrees in every particular. It is not an un- 

 common species here (Buffalo, N. Y. ) on grass and weeds in pastures and road sides, 

 especially where Carex and Juncus abound. 



It is a little smaller than the quadripunctata and rather broader in 

 proportion, and is quite readily distinguished from that species by the 

 dark wing veins and the more decided markings on the head and pro- 

 thorax. It is scarcely an eighth of an inch in length and fully one-third 

 as wide as long. 



A dark form which differs from the typical ones, so far as I can see, 

 only in the greater intensity of the markings is perhaps even more 

 common here than the typical form, and this I have found fairly plenty 

 and quite active in blue-grass lawn during the latter part of November, 

 so that we may be pretty certain that it hibernates under grass and 

 probably feeds more or less during mild weather of late fall and early 

 winter. It can also be considered as quite certain that it can live ex- 

 clusively upon grass, as in the localities where I have observed it it 

 could scarcely have been depending on other vegetation for its food. 



The Wavy-Spotted Leaf-Hopper. 



(Ally g us irroratus Say.) 



The propriety of including this species in a discussion of grass in- 

 sects may possibly be questioned, since its range of food plants is very 

 great. There is no question, however, that plants of the grass family 

 are among those most commonly affected by it, and I have found it 

 abundant in grass land, where evidently this was its only source of 

 food. It will be unnecessary, however, to detail its method of work, as 

 it agrees so nearly with other members of the same family, and all 

 methods of treatment must be based on similar principles. It may be 

 stated, however, that there is as yet no evidence, so far as I know, that 

 it hibernates in grass, and therefore those remedies based on that habit 

 in some of the species will not be applicable to this. Descriptions of 

 the species were published by Say in 1831, and since that time the spe- 

 cies has had frequent mention in entomological works, but only occa- 

 sional reference to it as an injurious species is made, and in these ref- 

 erences it is as often spoken of as a grain pest. 



The Destructive Leaf-Hopper. 

 (Cicadula exitiosa Uhler.) 



When attention was first called to this species it was from its attacks 

 on wheat, but that it is of equal if not greater importance as a grass 

 pest seems to me pretty clear after the observations of the present
