increase in the second submarginal cell ; but, when the super- 

 numerary cross-vein forming the discal cell is wanting, no 

 adventitious cross-veins are present in the second submarginal 

 cell. 



A specimen (fig. i) collected at Natroua, Pa., May 30, has 

 both discal cells open, although a slight stub on the left wing 

 indicates the position of the cross- vein. A specimen from 

 Edge Hill, Pa. (May 26), and one from Riverton, N. J. (Sept. 

 8 ), has only the discal cell of the left wing open. Among the 

 specimens in my collections are seven which have cross-veins 

 in the second submarginal cells, showing the following varia-

tions : One specimen (fig. 3) from Philadelphia (June 8) has 

 but one cross-vein on the left wing ; while one from Riverton 

 (May 14) has one on each wing ; one example from Philadel- 

 phia (June 8) has two on the right wing and one on the left, 

 and another has two on each wing. A specimen from River- 

 ton (Sept. 8) has three on each wing, but in different posi- 

 tions ; (fig. 4 shows the left wing, on the right the veins are 

 equidistant) ; while one from Shiloh, N. J., (Sept. i) has three 

 on the left and four on the right wing. But by far the most 

 singular variation is that shown by a specimen recently (Sept. 

 25) collected at Riverton. In this example (fig. 5) the second 

 submarginal cells are closed, the left wing having three cross- 

 veins and the right wing four.
