 and the riglit wings of p.iirs 1 !■ and KS. In (i, right wings of pairs 13, 14, 16 and 

 18, and both wings of 15, the right wing of IH sliows a rudiment of a second 

 branch near the wing tip; tlie great difference in the position of the forks of all 

 of these veins are noticeable. In one case, the left wing of 17, there is ;i third 

 fork near the wing margin and a reverse third fork near tlie margin of the right 

 wing. The base of the third discoidal is normally obsolete as is shown in nearly 

 every wing. In 10 the base of the first fork is broken up very badly, and in many 

 cases the lower branches of the two forks are badly twisted, but in spite of this 

 it will be seen that they are usually parallel. All veins dusky brown. Secondary 

 — (Figure 231, 1,2, 11, 12 and 19). Also variable in venation. Length from 1.3 

 nun. to l.lt mm., width from ()..'!.") mm. to (l..'>7 nun. N'orui.illv with two discoidals.

but often with only one. Subcostal undulate, usually most strongly curved at 

 the base of the second discoidal, may or may not extend to the tip of the wing. 

 First discoidal arises slightly beyond one-third the distance from the base to the 

 apex of the subcostal, may be obsolete at the base or wanting as sliown in 1 1 and 

 left wing of pair 12, straight, does not extend to wing margin, dusky brown. 

 Second discoidal arises near the middle of the subcostal at its greatest bend, is 

 considerably longer than the first discoidal, nearly straight or slightly bent out- 

 wardly. Style — (T'igure 2.S2, 7, 8, 9). Distinctly globular with a very narrow 

 neck and a base wider than the knob, yellow, with rather long coarse spines.
