and as seen from above considerably thickened at base; pedicel a little 
Icnger than wide, not produced on inner side as in kaalae; funicle joints 
all ramose on the inner side, the branches of the two middle joints 
longest, those of the first and sixth joints shortest, the sixth joint being 
similar to the fifth joint of kaalae; club a little longer and narrower 
than in kaalae. 
Scrobal impression finely lineolate-reticulate and somewhat more 
coarsely and evidently sculptured than the frontovertex, the fine lines 
more or less concentric around a pair of small triangular more deeply 
impressed smooth areas placed on either side of the short median carina 
on lower half of the impression, this earina not expanding above as in 
kaalae. 
In other characters of form, sculpture and pubescence not materially 
different from kaalae. 
General color moderately shiny black, the face below antennae and 
the frontovertex bluish black, the axillae and scutellum slightly bluish, 
the scrobal impression and mesoscutum with a dark greenish luster; 
antennae blackish, the scape and pedicel shining, the flagellum dull and 
more brownish; legs black with a luster like that of the body, but all 
the tarsi and the spur of the middle tibiae brownish yellow, with the 
apical joint of the tarsi more or less infuseated; wings hyaline, the veins 
dark brown. 
Length of body, 1.13; length of head, 0.438; width of head, 0.483; 
thickness of head, 0.221; width of vertex at posterior ocelli, 0.228; width 
of mesoscutum, 0.438; length of forewing, 1.11; width of forewing, 
0.499 mm.

Hypergonatopus n. g. 
Female. Head subhemispherical, with the face moderately inflexed; 
eyes rather large and the frontovertex moderately to strongly narrow, 
ranging from about two and one-half to six times longer than wide, the 
vertex with a distinct small fovea in each posterior corner; the oceelli 
arranged in a more or less acute-angled triangle, the posterior pair close 
to the eye-margin and more or less removed from the occipital margin; 
face with a broadly ovate or subcireular shallow scrobal impression, 
divided longitudinally by the broad, low protuberance between the an- 
tennae. Antennae inserted far apart close to the clypeal margin; the 
sockets more than twice their own length apart; scape slender, reaching 
considerably beyond the serobal impression; pedicel obeonical, about as 
long as the first three funicle joints combined; flagellum moderately 
clavate, the funicle joints short, mostly about as long as wide or a little
