REHN AND HEBARD 31 



Individuals with greatly produced tegmina and wings crop out 

 unexpectedly in several of the series, there being one from Phila- 

 delphia, one from Cornwells, Pennsylvania, several from Washing- 

 ton, a number from Virginia, one from Raleigh, one from Wil- 

 mington, North Carolina, several from Winter Park, North 

 Carolina, one from Albany, Georgia, and one from Live Oak, 

 Florida. 



The number of spines on the distal portion of the ventro- 

 external margin of the caudal femora was found on the examina- 

 tion of thirt}^ indiscriminately selected individuals in the largest 

 series, i. e. that from Tinicum, Pennsylvania, to vary from to 

 5. The exact figures are as follows: and 3 spines, 1 specimen; 



1 and 3 spines, 2 specimens; 2 and 2 spines, 3 specimens; 2 and 

 3 spines, 7 specimens; 3 and 3 spines, 10 specimens; 3 and 4 

 spines, 3 specimens; 3 and 5 spines, 1 specimen; 4 and 4 spines, 



2 specimens; 4 and 5 spines, 1 specimen. 



From this it is seen that in half the total the number of spines 

 on the same margin of the caudal femora agrees, while in an 

 equal number there is a more or less marked discrepancy. Very 

 marked discrepancy is, apparently, not as frequent as a discrep- 

 ancy of a single spine. 



In the coloration of the dorsal surface of the head and pronotum 

 w^e find every conceivable transition between one with that sur- 

 face of the clear glass greenish of the lateral aspects and of the 

 tegmina, to the other extreme with paired diverging dark brown- 

 ish lines extending caudad at least to the principal transverse 

 sulcus, between which lines the dorsum is more or less infuscate, 

 occasionally so much so that these bordering lines are distin- 

 guished with difficult}-. 



Distribution. — Coastal Plain and adjacent portion of the Pied- 

 mont Region of the eastern states from as far north as south- 

 eastern Pennsylvania (CoUegeville, Cornwells, Chestnut Hill, 

 Philadelphia and Tinicum) and southern New Jersey (north as 

 far as Westvillc and Ventnor) south to southern Floritla, west 

 as far as south-central Kansas (Wichita; Isely), Arkansas and the 

 Mississip])i Valley section of Louisiana (Buras and Milnelnirg), 

 and north in the Mississippi Valley at least as far as northern 

 Illinois (Rock Island; McNeill) and west central Indiana (Vigo 

 County; Blatchley).
