The range of this Nemobius extends practically all over 

 Florida, since Rehn and Hebard report it from Leon County, 

 Orange County, Duval County, Volusia County, Hillsboro 

 County, Bade County, and other points.* In Georgia it has 

 been found by Hebard and Rehn at Thomasville, southern 

 Georgia, and by the writer at Thompson's Mills, northern 

 Georgia, which is the second record of Nemobius ainbitiosiis 

 in this State. 



A very common Nemobius around Washington, D. C., in 

 autumn is Nemobius janus Kirby. This Nemobius is usually 

 found in the grass and leaves of damp soils by the roadside and 

 in fields. In such situations, if flat rocks are present, numbers 

 of the males and females find shelter beneath these. The note 

 of Nemobius janus is a weak, low-pitched, prolonged trill, al- 

 most indistinguishable from the trill of Nemobius palustris of 

 New England, except possibly a little louder. Around Wash- 

 ington this cricket continues to trill until December, if the 

 weather is mild. 



Gryllus pennsylvanicus var. abbreriatus Serville, also oc- 

 curs around Washington. Not infrequently it takes up its 

 quarters in the house, announcing its presence by its stridula- 

 tions, which are intermittent chirps, possibly louder than the 

 chirp of Gryllus pennsylvanicus. 



Gryllodes sigillatus Walker. This cricket is exceedingly 

 common at times in the greenhouses of the U. S. Department 

 of Agriculture at Washington, D. C. This cricket is distribut- 

 ed throughout the tropical region of both the Eastern and 

 Western Hemispheres, but has been rather widely introduced 

 into colder regions where artificial tropical conditions are ap- 

 proximated, as in many greenhouses. This cricket is a very 

 persistent singer. Its stridnlations are rather shrill, brief 

 chirps, so rapidly delivered as to produce an almost continuous 

 trill. The notes, though louder, recall the notes of a Nemo- 

 bius.
