one to three black, four orange yellow, the base black, the 
apical margin dark brown, five black with a subapical 
transverse, orange yellow band, six black. Pubescence of 
tergites one to four dull white, of following tergites black. 
Punctures of first three abdominal tergites coarse and ap- 
proximate, of following tergites finer and more widely sepa- 
rated; third tergite nearly twice as broad as long, fourth 
slightly more than twice as broad as long; first three ab- 
dominal tergites with a pair of longitudinal, dorsal carinse, 
parallel on first two tergites, slightly converging posteriorly 
on the third.

Holotype female: Yim Na San, east Kwantung, south 
China, June 14, 1936 collected by Mr. J. Linsley Gressitt, on 
loan deposit to the California Academy of Sciences. 
This species is easily distinguished from both of the pre- 
viously described species of the genus by the presence of 
two instead of three longitudinal carinse on the first three 
abdominal tergites. It differs further from A. formosana by 
the acarinate fourth tergite, the entirely black first three 
abdominal tergites, the largely yellow fourth, and the pri- 
marily black fifth tergite, and the black scutellum. It differs 
from A. clavata, in addition to the first character given, by 
the markedly different areolation of the propodeum and the 
nonpetiolate areolet. The color pattern is remarkably simi- 
lar to that of clavata. The basal median portion of the pro- 
podeum is asymetrical in the holotype, as shown in the figure.
