The insect is found everywhere in favorable situations on those 

 portions of the coastal plain treated in the present paper. It is 

 uncommon on the Piedmont plateau and in that region has been 

 found only at Appomattox, Virginia, and at Buckhead, Stone 

 Mountain and Warm Springs, Georgia.

Disassociation of the sexes caused Scudder to describe three, 

 instead of two, species at the time he erected the present genus. 

 After describing sphenarioides, he described rufovittata, and then 

 aptera from a single female. The second species is a combination 

 of four adult males of aptera and three immature females of sphena- 

 rioides. We here select as single type of A. rufovittata, the only 

 immature female of the type series of that species in the Scudder 

 Collection (the others, from the Cornell University, having also been 

 seen by us) , and in consequence we place rufovittata in the synonymy 

 under sphenarioides. 



The specimens from Pablo Beach are the largest we have seen of 

 the present form, being in length as follows: males 17-21.8, females 

 24.5-28 mm. This size is greatly exceeded in the southern race, 

 A. s. clara. The smallest individuals before us are from Brunswick 

 (male 15.4, female 20 mm.), the specimens from Jesup taken in 

 December are also unusually small. 



In the latitude of southern Georgia the species appears adult in 

 the largest numbers not earlier than late August, and is found numer- 

 ous in both adult and immature condition throughout the winter.
