In Florida this sombre-brown Tryxalid has been taken by me 

 at every place collections have been made, and, judging from the 

 numerous records, it doubtless occurs throughout the State, in- 

 cluding the southern keys. About Dunedin it is one of the most 

 common Acrididne of the winter months, occurring both as adult 

 and nymph in old fields and open pine w T oods. The adults, when 

 flushed, often fly long distances and frequently dive headlong 

 into a tuft of grass where they attempt to burrow out of sight. 

 In the pine woods, however, they often remain motionless until 

 closely approached, depending upon their color resemblance to 

 that of the pine needles for protection. 



The range of occi<lt'itt<ilis is given by McNeill as "the Gulf 

 States north to Tennessee and Georgia and west to Colorado and 

 Arizona." His mention of the last two states was evidently a 

 mistake as it cannot be substantiated from any other source, and 

 the only Tennessee record extant is that of the type by Saussure. 

 It occurs, however, as far northeast as southeastern A^irginia, 

 where Fox (1917) found it in late autumn near Deanes and Gil- 

 merton in "the low grassy undergrowth of open woodlands of oak, 

 loblolly pine and sweet gum/' North of Florida its known range 

 is therefore from Virginia west and south to Tennessee, Arkan- 

 sas, Oklahoma and Texas, it having been recorded from Bonita, 

 Denison, Houston and Dallas, in the latter State. Scudder's type 

 of A. suWii/aJhia (1875g, 511), now recognized as a synonym of 

 occidentalis, was from the last named place. 



The Chla'filtis canadenxls of Provancher (1876, 135), described 

 from Quebec, Can., is stated by Scudder (1877a, SS) to be the 

 same as his A. suWujaUnn. If so, it must have been based on in- 

 troduced specimens, as it has not since been noted north of Vir- 

 ginia. The description of the HtcnobotJints subconspersus of F. 

 Walker (1870, 755) from St. John's Bluff, Fla., agrees in most 

 particulars with A. occhlcntalis and it also may be regarded as a 

 synonym.
