sun gets low, and continues to stridulate into the evening-. 

 These locusts sometimes congregate in small colonies of half 

 a dozen or more in favored spots. It is a persistent singer, al- 

 though its notes are delivered at rather irregular and infrequent 

 intervals, a characteristic of most Scudderias. I have as yet 

 noted only the usual sh-sh-sh-sh at Thompson's Mills, Georgia, 

 where it is very common. 



Scudderia furcata Brunner, is possibly less common in cen- 

 tral Massachusetts than the preceding species. At least it is 

 much less frequently heard in stridulation. Its calls are de- 

 livered only at long and irregular intervals, and consist of a 

 single, keen, incisive zeep, or sometimes three slowly in suc- 

 cession, zeep-zeep-zeep. 



One warm, sunn}' afternoon in early September, 1910. in 

 order to locate and capture one of these katydids which had 

 just produced its single zeep, the writer lav down on the grass 

 in the vicinity and waited. The insect did not repeat its note 

 until nearly two hours later, after which the capture was easily 

 made. This katydid stridulates during afternoons and less 

 frequently at night. Its call is delivered only at long and ir- 

 regular intervals, so that much patience must be exercised to 

 locate a singer. Riley's description of the notes of Scudderia 

 furcata is very exact : "It consists of a softer zeep. zeep, 

 sometimes uttered singly but generally thrice in succession." 



A few times the writer has heard in this locality as late as 

 the last week of October the single incisive zeep of some be- 

 lated katydid. The call usually issued from the green foliage 

 of some shrub or apple tree which had delayed shedding the 

 leaves. It is possible that this was the call of Scudderia fur- 

 cata. Scudderia texensis had long since become silenced by 

 the cold days and nights of this season. 



The tiny Xiphidium fasciatum DeG. prefers the tangles of 

 weeds and grasses bordering the grass fields, and may often- 

 times be found in large colonies. Its notes are extremely faint, 

 and in manner of delivery are the exact counterpart of an 

 Orchelimum's notes. The staccato lisps nearly always precede
