Conocephalus fusco-striatus in North Georgia. 



By H. A. ALLARD, Washington, D. C. 



The careful observer of insect stridulations who visits' the 

 upper Piedmont region of Georgia in March or April, will 

 hear, during warm evenings, a loud, continuous, noisy buzz 

 sometimes in the tallest pines and oaks, or again in the weeds 

 and low herbage of fields. This is the stridulation of a cone- 

 headed grasshopper known as Conocephalus fusco-stnatus, 

 Redt. 



In this region the notes of this interesting locust together 

 with the familiar trillings of the ubiquitous field cricket, 

 Gryllns pefmsylvanicus, Burm.. are among the earliest insect 

 stridulations to be heard in spring. Here it is the only Cono- 

 cephalus to be heard in early spring, and judging from the in- 

 dividuals in song during warm evenings, it is a fairly common 

 species. At Thompson's Mills, Gwinnett County, where the 

 writer has observed this cone-headed grasshopper for several 

 years, the first singers of the season, appearing in March or 

 April, are usually located in the crowns of pine trees through- 

 out the settlement. Later in the season the young foliage of 

 oaks and other deciduous trees afford them sufficient conceal-

 and meadows, they become more terrestrial in their habits and
