same color as membrane, tubercles very sparse, minute and bearing black 
macrotrichia. 
Female. Brachypterous; length, 2.2 mm.; tegmen, 1.5 mm. Similar in 
structure and color to male, but the mark on tegmina greatly reduced. 
Described from two males and one female from Kumuwela 
from which the. holotype and allotype are selected, and two 
males from Nualolo, which have the mark on tegmina reduced 
and faint (Swezey, August, 1921), off Campylotheca. ‘Type 
No. 1055. 
Uburnia naenae sp. n. Figure 12. 
Male. Brachypterous; length, 2.4 mm.; tegmen, 1.8 mm. Lergth of 
vertex 1.7 times the width, apex rounded, projecting slightly in front 
of eyes, base considerably behind the middle of eyes; length of face 2.2 
times the width, widest in middle, sides slightly curved, median carina 
simple or slightly thickened at base, but not fureate. Antennae reaching 
to near middle of clypeus, second segment double the length of first. 
Tegmina reaching to base of pygofer. 
Opening of pygofer slightly longer than wide, margins entire, rounded, 
anal emargination large, anal angle not produced. Dorsal margin of 
diaphragm U-shape with a median armature projecting in middle and 
continuing to near orifice, the armature with a row of very fine spines 
on each side. Anal segment medium size, spines flattened laterally, bases 
well apart. In some specimens the anal spines are more acute than in 
the one figured. Genital styles reaching to anal segment, flat, apex trun- 
eate with the apical corners produced, the inner one more so than the 
outer, outer margin slightly concave, inner margin concave on apical half, 
convex on basal half, basal angle obscure. Aedeagus subtubular, slightly 
flattened laterally, slightly curved, a large, broad-based, flattened spine 
arises about the middle of the ventral aspect slightly on the right side, 
the base extending about one-third the length; on the left side there is 
a small spine and a couple of minute ones on apical dorsal and apical 
ventral aspect, orifice at apex on ventral aspect. 
Prothorax and mesothorax, head between ecarinae, front and middle 
coxae black or dark brown. Antennae, carinae of head, legs and hind 
coxae yellow, abdomen black or dark brown with base and small marks 
at side, along posterior margin of segments and the anal segment, yellow. 
Tegmina hyaline with a brown mark at apex of costal cell and another 
at apex of clavus with a very slight infuscation stretching between them; 
veins same color as membrane, tubercles sparse, minute, same color as 
veins, bearing black macrotrichia. 
Female. Brachypterous; length, 3.1 mm.; tegmen, 2.4 mm. In color 
somewhat lighter than male, the carinae of thorax light. 
Described from nine males and seven females from Alakai 
swamp (Szwesey, August, 1921), off Dubautia sp. The native
