of this grass. According to observations mapped in Bulletin io8 the 

 southern line of distribution runs into Kentucky and Tennessee, and 

 northward to include a part oi Colorado and the northwestern states to 

 Washington. All of which is included in the general distribution of 

 blue grass while to the south of this where the sod grasses do not 

 reach this species of leafhopper has not been observed. In Maine it is 

 less abundant and its place seems to be occupied in considerable part by 

 D. miiiki, and iiiiscUits and Athysanella acuticmida, all o^f which are com-

mon in the vicinity of blue grass and especially on Canadian blue grass. 

 The measures of treatment for the species that are the most available 

 would seem to be the burning of the grasslands where practicable in late 

 fall or early spring. This measure not only applies to inimicus but to the 

 related forms occurring in the same locality.

This is a small species with yellow and black stripes and two large 

 round black spots on the vertex. Length 3 mm. 



Usually an abundant species in grassy woodland but has been very 

 seldom seen this season and when collected it has been in rather open 

 pastures and meadows. It may be a rather rare species in the state and 

 if so has no economic significance.
