1915} Studies in Diaspinine Pygidia 73 
Aulocaspis rose. 
Micropores four—two between second lobe and anal aper- 
ture. These give rise to minute, short tubules terminating in 
two capita, the terminal one being armed with a minute piston. 
AULACASPIS ROSAE Bouche. 
Macropores numerous—situated in transverse rows at 
vestigial junctures of segments, and giving rise to very short 
sub cyllindric tubules, which are truncate at tips and armed 
terminally with short pistons.
