REHN AND HEBARD 79 



Florida and southern Mississippi show an elongation of the 

 distal section of the cercus, which is distinctly more attenuate 

 than in individuals from the Carolinas and northward. 



Biological Notes.— The earliest date we have for this species to 

 reach maturity in the northern states is July 15 at Pink Hill, 

 Pennsylvania, when and where an immature specimen in the 

 instar preceding maturity was also taken. In the southern states 

 it matures somewhat earlier, as our material shows dates as early 

 as July 8 (Sand Mountain, Georgia). At higher elevations in the 

 southern states the development of the species may be slower, as 

 our July material from points in Rabun County, Georgia, is 

 largely immature, but we lack specific information. At Dias 

 Creek, New Jersey, on July 20, both mature and immature spec- 

 imens were taken, and at Pink Hill, Pennsylvania, on July 1, 

 only immature individuals were found. On July 9, at Arlington, 

 Virginia, all material taken (five specimens) was in the instar 

 preceding maturity. 



The present species is a frequenter of the areas of dead leaves 

 and low undergrowth in pine and deciduous forest, occasionally 

 being more numerous along the edge of the timber than in the 

 depth of the woods. Its presence will often be signaHzed by the 

 patter on the leaves as it jumps away from the disturbing foot- 

 steps. The insects are so thoroughly protected by their color- 

 ation that it is often difficult to see them, even when moving, 

 much less when stationary. Their activities are chiefly noc- 

 turnal and work with a flash-lamp will sometimes reveal them in 

 many situations. 



Distribution. — The range of the species covers the Carolinian 

 hfe zone and also portions of the AUeghanian and Austroriparian 

 zones, and extends from central New England (Dedham, Massa- 

 chusetts and possibly New Hampshire) south to northern Florida 

 (River Junction), central Alabama (Opelika) and south-central 

 Mississippi (Natchez), west to the last mentioned locality. In 

 no case have we seen material from west of the Appalachians 

 in the northern portion of the range of the species, but southward 

 it occurs in the drainage basin of the Tennessee River, while it is 

 found as far north in the general Mississippi Valley region as 

 Holly Springs, Mississippi. In New York and New Jersey, the 

 range covers the coastal region and Costal Plain area, but in 



TRANS. AM. ENT. SOC, XLII.
