3800 feet elevation, September 6, 1919 (W. M. Giffard), is 
apparently a new species, but it would be inadvisable to name 
it at this time as the males in this genus show better distin- 
guishing characters than the females. It differs from Kilauea 
specimens of kaalae in having a slightly different shaped head 
and longer ovipositor and paler legs. The apex of the front 
and hind tibiae, the middle tibiae, and all the tarsi except the 
apical joint are brownish yellow, whereas only the tarsi and 
apical half of the middle tibiae are pale in kaalae. 
Nesencyrtus sexramosus n. sp. Figure 6. 
Male. Head somewhat thinner fronto-occipitally and of different 
shape than in the male of kaalae; as seen from above it is very strongly 
transverse or about three times wider than long, the anterior margin 
almost straight, the sides rounded, the occipital margin concave; as seen 
from the side it is only slightly thicker fronto-occipitally above than 
at the oral margin, the occipital margin appearing convex and the face 
coneavye above the antennal sockets; as seen from in front it is slightly 
wider than long and has roughly the shape of a keystone, being well 
rounded above, and with the sides converging from about the middle 
of the eyes nearly in a straight line to the broad oral margin; occiput 
sumewhat concave; eyes small, very broadly ovate, only slightly longer 
than wide; frontovertex about a half wider again than long, its anterior

margin not produced in front of the eyes; ocelli considerably smaller 
than in kaalae and arranged in an obtuse-angled triangle, the anterior 
ocellus about its own diameter from the anterior margin of the frons, 
the posterior pair about one-half their own diameter from the eye margins 
and three times as far from the occipital margin; cheeks longer than 
wide and somewhat longer than the eyes; face broad, convex below the 
antennal sockets and rather deeply concave above them to form a large 
scrobal impression. 
Antennae inserted far apart a short distance from the oral margin, 
of similar structure as in kaalae, but the scape is not twisted and in side 
view is rather strongly coneave above and convex on the ventral margin,
