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. 0. Essig, and at Dutch Flat, Towle and Blue Canon by 

 E. 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. 



Reparding this species Dr. L. O. Howard writes E. O. Essig: "This coccid 

 resembles in some respects Aulacaspis toumeyi but diiFers in that it has its 

 median lobes nenrly twice .is large and ]iaragciiituls 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".
