REHN AND HEBARD 201 



are strikingly marked with irregularly placed spots and dots of 

 coral red; these in the immature condition are much darker, 

 reddish brown in color, and are still evident in dried mate- 

 rial. Tibiae green, much suffused with brown. Face capucine 

 orange with a median vertical stripe of mahogany red extending 

 from the vertex to the base of the clypeus, genae clouded with 

 mahogany red. Dorsum of head and pronotum with a broad me- 

 dian band of mahogany red, the remaining lateral portions of the 

 occiput and pronotum including the upper portions of the lateral 

 lobes capucine buff, the area between this and the green portion 

 of the lateral lobes clouded with mahogany red. Eyes very deep 

 mahogany red. Tegmina and wings transparent, salmon buff. 

 Distal three-fifths of male abdomen, including cerci, orange 

 rufous. Abdomen and ovipositor of female sudan brown, shaft 

 of latter washed with green. Genicular areas of caudal femora 

 suffused with reddish brown. 



The material before us shows httle local size variabilitj^; in 

 southward distribution there is a slight increase in size. 



All of the specimens before us from New Jersey and Maryland 

 are brachypterous, while those from North Carolina are all 

 macropterous. 



The ventro-external margins of the caudal femora are armed 

 with small but heavj^ spines, (approximate average, three and 

 four) ; these are found in the thirty-two perfect specimens before 

 us as follows: 



Number of spines, 0-0 0-1 1-2 2-2 2-3 2-4 2-.5 3-3 



Number of specimens, 1113 1127 



Number of spines, 3-4 3-.5 3-6 3-7 4-4 4-5 5-5 6-6 



Number of specimens, 3 2 113 3 1 1 



The series from which the present species is described was 

 taken in a heavy growth of panic grass (Panicum virgatum), one 

 to one and one-half feet high, interspersed with various marsh 

 plants in a limited marshy area on the border of a brackish stream. 

 Two hours strenuous and continuous beating was nocessaiy to 

 secure the series, as the species was very scarce. Though not un- 

 usually active in their movements, the insects proved to possess 

 extreme facility in concealing themselves. The species is known to 

 range from Cedar Springs, New Jersey, to Raleigh. North Carolina.
