940 LIST OF HOMOPTEROUS INSECTS. 



wards recedes, and forms a very obtuse angle ; the distance between 

 this angle and the tip of the brand, is less than that between the tip 

 of the brand and the tip of the fourth vein ; space between the first 

 and second branch veins at the base almost half of that between 

 them at the tips ; first vein nearly straight, diverging rather more 

 from the second, than the second does from the third ; its tip is 

 much nearer to the tip of the second vein than to the base of the 

 wing ; second vein curved slightly, first outward, then inward in its 

 course, wherein it slightly diverges from the third vein, to whose 

 base it is a little nearer than to the base of the first vein ; its tip is 

 much nearer to the tip of the third than to the tip of the first vein ; 

 the third vein is curved slightly and irregularly inward, so as in 

 some degree to conform to the fourth vein ; its base is much nearer 

 to the base of the second vein than to that of the fourth vein ; its 

 first fork begins at half the length, and its second beyond half the 

 length of the first; the tip of its second fork is hardly farther 

 from the tip of the fourth vein than from the tip of its first fork, 

 and the space between its forks is much less than the space be- 

 tween its tip and that of its first fork, and the latter space is rather 

 less than the space between its tip and that of the second vein ; 

 fourth vein much curved throughout its length ; its tip a little 

 nearer to the tip of the brand than to the tip of the second fork, 

 and the distance from its base to the tip of the brand is only 

 half that to the base of the third vein ; the rib-vein of the 

 lower wing is slender, and continues to its tip ; it has two straight 

 veins diverging slightly from each other, and consequently rather 

 more distant at the tips than at the base; the space between 

 them at the base is less than that between the first and the base 

 of the wing, and still less than that between the second and the 

 tip of the wing. 



Var. Third vein in one wing without a second fork. 



Var. A fork proceeding from the angle, which is formed by the 

 second fork of the third vein. 



Var. The part of the third vein between the forks longer than 

 either the preceding or the succeeding part. 



Var. The second fork with double its usual length. 



Var. A third fork proceeding from near the base of the first 

 fork of the third vein. 



The winged male. The fourth feeler-joint is more than half 

 the length of the third ; the fifth is shorter than the fourth ; the 

 sixth than the fifth, and the seventh than the sixth.
