Augusta. One, intermediate in color and structure. 



Tybee Island. Two, rubiginosa phase. 



Isle of Hope. One, alutacea phase. Three, intermediate in color. 

 Four, rubiginosa phase. The males (six) show no other structural 

 intermediates, but specimens intermediate in color have deep femora. 



Sandfly. Five, alutacea phase. Four, rubiginosa phase. 



Brunswick. Eleven, rubiginosa phase. One, alutacea phase. 



Jesup. Seven, rubiginosa phase. Four, alutacea phase. Males 

 show little, and then connected, difference in fastigial width; costal 

 width variation very considerable, but connected. 



Groveland. One, rubiginosa phase. 



Billy's Island. Fourteen, rubiginosa phase. One, intermediate. 

 One, alutacea type. 



Jordan's. Four, rubiginosa phase. One, alutacea phase. 



Suwannee Creek. Eighteen, rubiginosa phase. One, alutacea 

 phase. The latter (cf ) has the frontal costa no narrower than in 

 numerous decided rubiginosa phase individuals. 



Homerville. Five, rubiginosa phase. One, alutacea phase. Struc- 

 tural differences in fastigium in these but little and connected, ex- 

 tremes decided, as in the case of femoral depth. 



Albany. Four, alutacea phase. One, rubiginosa phase. Males 

 (three) all alutacea, one has frontal costa typical, others have this 

 very much broader. 



Spring Creek. Fifteen, rubiginosa phase. 



Jacksonville. Eleven, rubiginosa phase. Four, alutacea phase. 

 Those collected by ourselves (seven rubiginosa, two alutacea) show no 

 marked structural differences in fastigium in striped and unicolorous 

 individuals. Head width little variable and apparently with extremes 

 connected. Femoral depth difference appreciable. 



Atlantic Beach. Thirty-two, rubiginosa phase. Two, inter- 

 mediate (maculate tegmina type). Twenty-one, alutacea phase. 

 Specimens of alutacea phase have the frontal costa of usual rubiginosa 

 width. 



Live Oak. One, alutacea phase. 



We also have before us from New Jersey alone, one hundred and 

 twenty-eight specimens collected in southern New Jersey by Dr. 

 Henry Fox, 69 a series of twenty-two from Stafford's Forge with exact 

 habitat data, another of twelve from Taunton and a considerable 



69 Recorded by that author as "S. alutacea (Typical race); S. rubiginosa 

 (= rubiginosa phase of alutacea), and S. sp. cf. obscura (= unicolorous phase of 

 obscura)." Proc. Acad. Nat. Sci. Phila., 1914, pp. 507-509, (1914).
