New Harmony, Ind., September. Staten aud Long Islands, 

 X. Y., August, (Davis.) The only known Indiana specimen of 

 this large, long-headed Tettigouiid is the female type of my COH- 

 occirtmlns bruneri (1903, 367) taken at New Harmony, Posey Co., 

 by the late Arthur Dransfield. Not being able to identify it by 

 the literature available, it was sent to Prof. Lawrence Brunei-, 

 who wrote me that it was evidently an undescribed form. Karney 

 (1907, 30) first placed it as a synonym of cxiUscanonts and com- 

 parison with State Island females of that species shows that he 

 is probably correct, though the Indiana specimen is distinctly 

 larger and with longer fastigium than any of those received from 

 Davis. 



The types of Davis were found amongst the cat-tails that grew 

 on the salt marshes of Staten Island, and it ranges along the 

 Atlantic coast from New Haven, Conn., to Raleigh, N. Car., and 

 Mississippi, and inland to Clarksville, Tenn., Thompson's Mills, 

 Ga., and Dallas, Texas. Of its habits Davis (1887) says: "This 

 insect keeps very close to the ground, hiding well in the vegeta- 

 tion, and is not easily discovered. The sound produced when 

 stridulating is very faint, not louder than that made by Grylltts 

 abJn-rriatiis and I was much surprised to hear such a faint song 

 from so large an insect. I have in consequence named it the 

 'slightly musical Conocephalus.' ' Later (1889) he adds that 

 "c.rilifH-iinoi UK devours the heads of the meadow grass (Kpartiiid) 

 and is such a slow singer that one can easily estimate the num- 

 ber of times one wing is drawn over the other, which is about 115 

 times a minute." Again (1911) he says that the song varies con- 

 siderably in loudness according to the age of the singer, while its 

 volume is also to some extent dependent upon the temperature.
