572 FAMILY VII. TETTIGOXIIDJE. THE KATYDIDS. 



Walker (1904a, 339) says that C. brevipennis is "nearly as com- 

 mon as fasciutits in southern Ontario, but becomes scarcer to the 

 north of Muskoka. It reaches maturity about the first of August 

 and remains well into October. It was not very common in Al- 

 gonquin Park where it seems to prefer the vicinity of rank herbs 

 and bushes in more or less shady spots. The note of the male 

 is very like that of fasciatus. The zips are emitted at intervals of 

 about one second, one or two being produced at a time." 

 Of the song of C. brevipennis Allard (1911) has written: 

 "I could not determine its stridulations in the field, so a number of 

 males and females were placed in a pasteboard box together with some 

 grass. In a few minutes a number were in continuous song throughout 

 the afternoon and night. The stridulations of this Xiphidium are the 

 least audible of any locust the writer has ever observed. Although a per- 

 sistent singer, the notes become inaudible only a few feet away. In the 

 fields they are quite lost amidst the sounds of rustling foliage, the chirp- 

 ings of crickets, etc. The notes of brevipenne are very brief and much 

 more hurried in their delivery than those of X. fasciatum. In this respect 

 they approach more nearly the dainty stridulations of X. nemorale Scudd. 

 In the song of brevipenne usually only one or two almost inaudible staccato 

 lisps precede one, two or even three of the brief, faint phrases, tseeeeeee- 

 tseeeeeee. These are of much longer duration in the song of fasciatum, 

 and are rarely heard without the preceding staccato lisps which are of in- 

 definite number." 



In addition to JT. ensifer Scudder, E. & H. have made T. fjofs- 

 sypii Scudd., (1875, 461), described from Texas and Mississippi, a 

 synonym of C. brevipennis.
