name of the various species of this plant, as well as of some 
of the larger Raillardiae, is ‘“naenae.” 
There is considerable variation in color from the darker 
to the lighter forms in both sexes, in some the dark mark on 
tegmen is distinct and runs basad along Sc + R. This species 
I place near J. gerani. The aedeagus recalls that of Nesores- 
tias nimbata. Type No. 1054. 
Ilburnia viridis sp. n. Figures 13, 13a. 
Male. Brachypterous; length, 2.1 mm.; tegmen, 1.5 mm. Length of 
vertex subequal to width, base slightly behind the middle of eyes, apex 
rounded, produced slightly in front of eyes, carinae obscure; length of 
frons 1.8 times the width, widest slightly on apical third, median carina 
obscure. Antennae reaching near to middle of elypeus, second joint 
double the length of first. Tegmina reaching to base of pygofer. 
Pygofer considerably wider than long, ventral margin shallowly and 
roundly emarginate and thickened; lateral margins round, entire; anal 
emargination moderate, enclosing slightly more than half the cireumfer- 
ence of anal tube, anal angles rounded, not prominent. Diaphragm fairly 
long, dorsal margin biconcave, the middle produced into a point, the 
armature forming a thin plate from dorsal margin to orifice, which in 
lateral view has three or four irregular serrations. Anal segment moder- 
ately large, anal spines moderately large, broad, flattened laterally. Geni- 
tal styles narrow, long, reaching to anal segment, diverging, inner margin 
sinuate, outer margin concave in middle, apex truncate, basal angle mod- 
erately developed. Aedeagus long, slender, subecylindrical, the apical half 
straight, basal half slightly eurved upward, a row of small teeth along 
the ventral aspect of apical half or two-thirds, and three or four on dorsal 
aspect in middle, a few small teeth on left side near apex; orifice on 
left side at apex. 
Light green, legs and pygofer slightly lighter in color, arista of an- 
tenna and spines on legs dark brown. Tegmina hyaline tinged with 
green, veins light green. 
Female. Brachypterous; length, 2.4 mm.; tegmen, 1.8 mm. Similar 
in color to male. Ovipositor light brown or fuscous. 
Described from two males and thirteen females from Nua- 
lolo, off Phyllostegia (Swezey, September, 1921). This species 
I place near to J. boehmeriae, but it is quite distinct. Type 
No. 1053. 
Ilburnia pilo sp. n. Figures 14, 14a. 
Male. Brachypterous; length, 2.1 mm.; tegmen, 1.4 mm. _ Vertex 
longer than broad, projecting somewhat beyond eyes, apex broader than 
base, slightly rounded, base considerably behind middle of eyes; length 
of frons twice the width, broadest in middle, sides slightly arcuate. An-
