some parasites might be reared. Toward the end of September 
and in the early part of October, 1918, minute, active chalcids 
were bred from the scale, which differ from Prospaltella berlesei 
Howard. Specimens of the latter species were received from 
Prof. Antonio Berlese some time ago. This new parasite, which 
I name Prospaltella niigatz, has long, expanded forewings, and 
remarkably broad thorax. Segment 2 of funicle of this new 
species is longer than segment 1; in Prospaltella berlesei seg- 
ment 1 is the longer. ° 
The male is unknown.
