Inhabits Texas, Arizona, Matamoras, Mexico, the Eastern United 

 States generally, Cuba, and New Granada. It occurs at considerable 

 altitudes on the Black Mountains of North Carolina, and is not unfre- 

 quent upon grassy and shrubby spots in Georgia, and Florida. Miss 

 Modeste Hunter collected it near Orange Springs, Florida, in the month 

 of July. 



In Maryland, it may be found on low spots in the meadows where the 

 plants and grass grow rich and dense, in June, August, September, and 

 October. It appears to lay eggs in late spring and toward the latter 

 part of summer. 



The Cuban form is usually larger, and has the lateral a^.^gles longer 

 and more slender than in those from the United States.
