in the same language ; tlie experiment proved tliat the insects could 

 hear as well as sing. 



This species is exceedingly shy, and the observer must be patient 

 who would hold converse with it. One insect which I had disturbed, 

 and beside which I was standing, could not, at first, decide to resume 

 his song; he was afraid of the intruder, but enticed by a neighboring 

 songster, gave utterance several times to a barely discernible, short 

 click, or H ; after five or six of these efforts, his desires overcame bis 

 fears. The note by day is hznui, and lasts for one third of a second.

Note of riianeroptera curvicauda by day. 



The night song consists of a repetition, ordinarily eight times, of a 

 note which sounds like tcliio. It is repeated at the rate of five times 

 in three quarters of a second, making each note half the length of 

 the day note.

Note of Phaneroptera curvicauda by iii<)flit. 



The song of the common meadow grasshopper — Orchelimum vul- 

 gare — is more complicated. Commencing with ts, it changes almost 

 instantly into a trill of zr ; at first there is a crescendo movement 

 which reaches its volume in half a second ; the trill is then sustained 

 for a period, varying from one to twenty seconds (generally from sLx 

 to eight seconds) and closes abruptly with p. This strain is followed 

 by a series of very short staccato notes sounding like jip !, repeated 

 at one-half second intervals; the staccato notes and the trill alter- 

 nate ad libitum. The staccato notes may be continued almost indefi- 

 nitely, but. are very rarely heard more than ten times in succession ; it 

 ordinarily occurs three or four times before the repetition of the 

 phrase, but not more than two or three times when the phrase is 

 not repeated. I have known it to be enth-ely omitted, even before 

 the repetition of a phrase. The interval between the last jip ! and 

 the recommencement of the phrase never exceeds one quarter of a 

 second. The night song differs from that of the day in the rarer 

 occurrence of the intermediate notes and the less rapid trill of the 

 phrase; the pitch of both is at B flat.
