408 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERa) 



generally used to designate green individuals of the present species 

 by recent American authors. 



The green color phase is somewhat more frequently encountered 

 than the brown. 



The present species is found almost everywhere in the southern 

 United States; it inhabits the forest undergrowth, fields and semi- 

 marsh situations. Over much of its range it is one of the earliest 

 Tettigonids to appear, adults being found in south Georgia in late 

 March. The few midsummer records, accompanied by numerous 

 early winter captures and the finding of specimens in midwinter 

 apparently hibernating, suggest that the species may be double 

 brooded, or that appearing adult very late in the fall it is one of the 

 few species of the family in that latitude to pass the winter in the 

 adult condition. The song is a very loud, sharp, z-z-z-z-z-z-z- 

 z-z-z-z, indefinitely prolonged; when closely approached a con- 

 stantly recurring impulse gives an audible krzzzzkrzzzzkrzzzz 

 with no break, though a recurrent clicking is to l^e heard, as de- 

 scribed by us recently .^^ It was heard frequently at twilight in 

 the spring of 1904 at Thomasville, Georgia, the song of brown 

 males being at that time of day not as intense as that of green 

 males previously captured at night; this leading the junior 

 author to think that the supposed fusco-striatus was a less loud 

 singer than the supposed mexicanus.^- Such mistakes are' likely 

 to occur in field observations unless extreme care is exercised.^^ 



The species is widely and generally distributed from Washing- 

 ton, District of Columbia, southward over the entire southeast- 

 ern United States and thence westward to central Texas, the 

 westernmost record in this region being Carrizo Springs, Texas, 

 and the northernmost definite record Stillwater, Oklahoma. In 

 the Pacific drainage of the southwest, the species is known on 

 the Mexican border from Benson, Arizona, to San Diego and Los 

 Angeles, California. 



Specimens Examined: Previously recorded as mexicanus and Jusco- 

 striaius, 36. Here recorded, 109 ; 43 males, 59 females, 1 immature male and 

 6 immature females.
