SUBFAMILY IV. COXOCEPHALIXJE.

''moderately frequent in open undisturbed dry grasslands, espe- 

 cially partial to Antlroitoyon, but taken also on Dniitlioiihi.'" In 

 the dune region of northwestern Illinois Hart found it "common 

 in damp grassy bottoms of old blow-outs," and in Nebraska 

 Bruner (1893a) says it ''is found over the entire State but is 

 more common southward than elsewhere." Regarding the song 

 of the male, Allard (1914) says: 



"The notes of this species are much louder than those of any Xiphidion 

 known to me. No staccato lisps precede the long lisping monotone s-s-s-s- 

 s-s-s-s-s-s, which may continue several minutes without pause. Its note is 

 thus similar to that of certain species of Neoconocephalus which have 

 acquired the habit of prolonged stridulation. Although the Xiphidions 

 usually keep well within the grass and low herbage of fields and meadows, 

 the writer has observed X. strictum resting on shrubs several feet from 

 the ground during stridulation."

Tappahannock, Va,, Sept. 10 (Fox). The types of K. & H. 

 were from Cedar Springs, X. Jer., and were taken from "a heavy 

 growth of panic grass, Pan'u-inn rirytttittii L., interspersed with 

 various marsh plants in a limited marshy area on the border of a 

 brackish stream."
