170 Psyche [Sept. -Dec. 
scutellum pale; abdomen with two segments toward tip reddish 
above. Fore wings with dark spot over the short vein below 
divisory cell, more over base of radial sector; dark spot at base 
of stigma, another over last cubital cross-vein, one or two 
cross-veins before also brown, outer gradates brown, also base 
of outer forks, few cross-veins dark at one end, mostly pale. 
In hind wings the stigma dark at base, veins mostly pale, outer 
gradates partly dark. 
In fore wings the costal area fully equal to radial area in 
width; fifteen radials, eight cubitals beyond third cubital cell, 
eight or nine inner gradates, six outer ones, inner row extended 
basally, four cubital cross-veins beyond its origin, slightly di- 
vergent from outer row. In hind wing eight cubital cross- veins, 
seven inner and six outer gradates, inner row extended basally 
a little. 
Fore wing 15.5 mm. long, 5.5 mm. wide. 
One from Barro Colorado, Canal Zone, August (F. H. Hull). 
Type M.C.Z. no. 25657. 
Neula Navas 
I consider my Allochrysa titan as belonging to this genus. In 
the genotype from Colombia Navas shows an intermediate row 
of gradates; in titan the row is broken, two in one wing, four 
in other; however, it agrees with Neula in many other points. 
The radial area is broadest toward base (not in middle as in 
Nodita) ; and at middle (half way from origin to stigma) the 
radial sector is much nearer to radius than to medius. The 
costal area is not as broad as the radial area; the antennae are 
very long; it differs from Leucochrysa chiefly in having the 
radial sector more sinuous. 
Neula titan Bks. 1915 
I have seen only the type. 
The palpi are partly black; the pronotum broad, the trans- 
verse groove near the hind border, in front of groove there is a 
slight elevation. The postcubital area about twice as broad as 
the cubital. The third cubital cell has one branch toward the 
margin and it soon forks, one part running into the fork of 
first anal vein, the other reaching the hind margin, alike in both 
fore wings. There are 20 to 22 radials, 13 to 14 inner gradates,
