a large and small lobe. Fourth and fifth lobes are rudimentary. 
There is one spine immediately on the outer edge of each lobe 
or right after; there are also gland spines; the first one between 
second and third lobe; one between third and fourth lobe, and 
between fourth and fifth there are from three to four. After the 
fifth lobe the gland spines vary from six to nine. Out of twenty 
scales mounted there are five pairs of marginal glands near the 
margin; one gland directly in center of median lobes; four other 
glands resembling marginal glands; just back of first, second 
and third marginal glands numerous smaller ones scattered back- 
wards from near the margin into the abdominal segments. Anal 
aperture just even or below posterior group; genital aperture 
just below anterior group. Genital aperture very faint and is 
generally overlooked. 
This scale has been collected at several points in the past by 
different collectors. At Bowman, by H. H. Bowman, at Colfax 
by E. O. Essig, and at Dutch Flat, Towle and Blue Canon by 
HE. K. Carnes, E. J. Brannigan and B. B. Whitney. It was 
invariably found on Manzanita sps. at an elevation ranging from 
1,622 to 4,701 feet above sea level. This, however, I believe to 
be the first recorded description. 
Regarding this species Dr. L. O. Howard writes E. O. Essig: “This coccid 
resembles in some respects Aulacaspis towmeyi but differs in that it has its 
median lobes nearly twice as large and paragenitals more numerous. It has been 
received before on Acrostaphylos from mountains near Claremont, Calif. This 
appears to be a very interesting scale and for some time has been placed in our 
unidentified material of this genus”.
