The range of this species is now known to extend eastward to the 

 coast in Virginia (Virginia Beach), but in North Carolina it has not 

 been taken lower than Raleigh, while in Georgia it is only known 

 from elevated localities in the northern part of the State (Sand 

 Mountain and Blue Ridge). 



The species was scarce everywhere and was found in the moist 

 situations usually frequented, while at Fredericksburg it was also 

 encountered on rather barren hillsides.

Through the kindness of Mr. Franklin Sherman Jr., we have 

 been able to examine previously recorded material of this form from 

 Blantyre (IX, 1906; R. Woglum, 1 &) and Raleigh (X, 1907-XI, 1908; 

 F. Sherman Jr., 1 ci", 1 9 ), North Carolina. The Blantyre specimen 

 is perfectly typical punctulatus, while the Raleigh material shows a 

 faint approach toward punctulatus arbor eus in the slightly greater 

 thickening of the tubercle of the male subgenital plate. The Raleigh 

 specimens are, however, clearly true punctulatus. We have made a 

 careful study of all the available material of punctulatus and arbo- 

 reus, some thirty-five specimens in all, and are convinced that 

 Scudder's suggestion that arboreus might be only a geographic race 

 of punctulatus is correct. Aside from the larger size of the southern 

 specimens, the only constant, easily appreciated character which 

 we can find to separate the two forms is, that in p. punctulatus the 

 tubercle of the male subgenital plate is smaller, less produced and 

 thinner, while in p. arboreus the same structure is larger, more distinctly 

 produced and thicker and more inflated. The metazona of the pro-
