with a broad, complete band of dense, ap- 
pressed, golden pubescence. Pubescence on 
posterior margin of second tergite somewhat 
ferruginous at middle and pale laterally. A 
very small tuft- like golden pubescence is 
recognizable at middle of posterior margin 
of second tergite. First tergite and anterior 
portion of second covered with rather dense, 
erect, long, pale pubescence. Pygidium with 
dense, erect, long, pale pubescence only at 
sides. Posterior margin of second to fourth 
sternites with rather dense, erect, long, pale 
pubescence. First tergite with dense, moder- 
ate punctures, posteriorly the punctures close 
and confluent; second tergite with moderate, 
well-separated punctures. Tergites III to V 
with small, well-separated punctures. Pygid- 
ium minutely, longitudinally striate except 
apically and with close, small, confluent 
punctures at sides. First sternite with a prom- 
inent, median, longitudinal carina, in profile 
appearing roundly emarginate; second stern- 
ite with sparse, moderate punctures except 
the posterior margin with small, close punc- 
tures; sternites III to V with sparse, moder- 
ately small punctures, denser at the posterior

This new species is closely related to 
Timulla (Trogaspidia) alhertisi (Andre, 1896) 
from New Guinea, but the latter is quite dis- 
tinct from this species in the following points: 
' Tete avec des soies noires eparses sur le 
front; vertex largement recouvert dune bandc 
de pubescence fine, seree, d’un jaune dor 
soyeux, echancree en arc en avant. Thorax 
herisse de soies noires sur le dos . . . et recou- 
vert sur les flancs dune pubescence jauna- 
tre . . .” (E. Andre, 1896, Etudes sur les Mu- 
tillides existant dans les collections du Musee 
Civique de Genes. Ann. Mus. Civ. Stor. Nat. 
Genova II, 17: 70-71). 
This species is known at present only from 
the unique female described above. It is 
named in honor of Professor Esaki of the 
Kyushu University, who first discovered the 
mutillid wasp in Micronesia. 
I wish to express my sincere thanks to 
Professor Esaki for his generosity in placing 
the material at my disposal.
