Acerataspis sinensis Michener, n.sp. 
Female: Length 9 mm. (with the apex of the abdomen 
turned down). Head rather small, black, pubescence dull 
white, upper three-fourths of area between anterior margin 
of clypeus and antennal sockets yellow, lower margin of this 
yellow area arcuate concave, inner ocular orbits narrowly 
brown, more broadly black toward upper part of yellow area, 
so that yellow does not reach ocular margins ; keel between 
antennal sockets yellow. Face below antennal sockets coarsely 
and confluently punctured ; rest of head with smaller punc- 
tures, for the most part separated by less than their diam- 
eters; ocelli large, distance between posterior pair greater 
than an ocellar diameter, slightly less than distance to eye 
margin ; gense convex, about one-half as wide as eye. Anten- 
nae dark brown, lighter beneath than above ; mandibles dark 
brown medially; palpi dark brown. Thorax black, pubes- 
cence dull white, a minute dull yellow spot below each tegula, 
inner margins of scutellar processes brown, tegulae dark 
brown. Thorax, largely coarsely and closely punctate, 
lower lateral portions of pronotum impunctate, with about 
six longitudinal ridges; sternauli with punctures sparser 
than elsewhere on mesepisterna ; posterior margins of mese- 
pisterna and entire metapleura shining and nearly impunc- 
tate, the latter sclerite with a few small, scattered punctures 
above ; basal depression of scutellum with three longitudinal 
carinse ; posterior processes of scutellum connected by a Ca- 
rina, the short median section of which is along the posterior 
margin of the scutellum ; metanotum with a small, elevated, 
median area, margined on each side by an angulate carina ; 
propodeum with a rather small basal median area, posterior 
to which is a broad area (see figure), completely separated 
from lateral apical areas. Fore legs dark brown, apices and 
anterior surfaces of femora yellow, and bases and anterior 
surfaces of tibise yellow ; middle legs dark brown ; hind legs 
black. Wings grayish as a result of numerous long hairs in- 
serted on the nearly hyaline membrane; wing veins and 
stigma very dark brown ; areolet not petiolate, but costally 
directed side very short. Abdomen with sterna yellow ; terga
