slightly curved near the base, straight from thence to the 

 tip, which is very little in front of the tip of the wing ; 

 second, third, and fourth nearly straight. Species 7. 

 d d. Costal vein ending at or before half the length of the wing. 

 e. Costal vein ending at half the length of the wing, emitting 

 a veinlet which extends to about five-sixths of the length ; 

 mediastinal vein ending at much beyond half the length of 

 the costal. First veinlet slightly curved near the base, 

 straight from thence to the tip, which is hardly in front of 

 the tip of the wing; second, third, and fourth nearly 

 straight. Species 8. 



e e. Costal vein ending at half the length of the wing, emit- 

 ting a veinlet which extends to about seven-eighths of the 

 length ; mediastinal vein ending at very little beyond half 

 the length of the costal. First veinlet slightly curved in- 

 ward near the base, nearly straight from thence to the tip, 

 which is very little in front of the tip of the wing ; second, 

 third, and fourth very slightly undulating. Species 9. 

 e e e. Costal vein ending at half the length of the wing, emit- 

 ting a veinlet which extends to three-fourths of the length ; 

 mediastinal vein ending at beyond half the length of the 

 costal. First veinlet very slightly curved along the whole 

 length, ending at some distance in front of the tip of the 

 wing ; second, third, and fourth nearly straight. Sp. 10. 

 e e e e. Costal vein ending at hardly half the length of the 

 wing, emitting a veinlet to beyond three-fourths of the 

 length ; mediastinal vein ending at about five-sixths of the 

 length of the costal. First veinlet almost straight, ending 

 at some little distance in front of the tip of the wing; 

 second, third, and fourth nearly straight. Species 11. 

 e e e e e. Costal vein ending at a little before half the length 

 of the wing, emitting a veinlet which extends to about five- 

 sixths of the length ; mediastinal vein ending at full two- 

 thirds of the length of the costal. First veinlet very 

 slightly curved inward along the whole length, ending at 

 very little in front of the tip of the wing ; second, third, 

 and fourth nearly straight. Species 12. 

 c c. Radial vein wholly united with the cubital. 



d. Costal vein ending at much before half the length of the 

 wing, emitting a veinlet which extends to four-fifths of the 

 length ; mediastinal vein ending at before two-thirds of the 

 length of the costal. First veinlet much curved near the 

 base, nearly straight and parallel to the fore border from 

 thence to the tip, which ends at a little in front of the tip 

 of the wing ; second, third, and fourth nearly straight. Spe-
