segment in the short-winged females. The color is yellow or 

 yellowish gray with dark markings which form two rather in- 

 definite stripes on the pronotum and elytra. The antennae and 

 legs are black with yellowish bases or yellow with black hairs 

 and spots. 



The nymphs are yellow marked with black, the general 

 color being quite dark in the early instars and becoming lighter 

 with the successive moults. 



Distribution 



The range of the species is evidently throughout a large 

 part of Northern Europe and North America but in this coun- 

 try it has been especially noticeable in Eastern Canada, New 

 England, New York and West into Ohio. Reports from a 

 number of states establish its occurrence in large numbers and 

 the records given support the view that it is an old world 

 species which has gained introduction within the past century. 



Believed to be an Introduced Species 



With the evidence available there seems to be good reason 

 to believe the species to have been introduced from Europe at 

 some time not later than the early part of the last century, 

 probably not earlier at best than about 1800 and, if we may 

 give weight to the first records by Uhler and Provancher we 

 may suppose an introduction in New England or at Quebec 

 or some of the maritime provinces of Canada, perhaps equally 

 probable for Nova Scotia, New Brunswick or Quebec. From 

 any of these localities the dispersal might easily reach the other 

 localities concerned in the course of a few decades though 

 without artificial assistance its progress must be slow. 



Evidence in favor of the species being an introduced one 

 may be summed up briefly as follows: 



First: It has been a common insect in Europe for an indefi- 

 nite period, covering a large area and doubtless as- 

 sociated with the cultivated grasses to which it seems 

 so closely restricted here. 



Second: The species was not known in America until about 

 1830 when it was collected by Harris as noted by Uhler 

 and later recorded by Provancher altho a number of
