•New variety ulmi. Female: Scale white, about 2\ mm. long, moderately broad, 

 extiviffi yellowish brown. Male : Scale very small, obscurely tricarinate. exuvium pale 

 yellowish. Female brown : Five groups of ventral glands, median 18, cephalolaterals 

 15, caudolaterals 16; median lobes contiguous, rounded at ends, oblit|uely truncate at 

 sides, not notched. Secoud lobes much smaller, consisting of a larger notched por- 

 tion, and beyond that a small separated portion, and between these a spine. Third 

 lobes small and nearly obsolete. A spine laterad of each median lobe. A long spine- 

 like plate laterad of third lobe, beyond which, at some little distance, is a notch, 

 followed by a sort of rudimentary broad crenate fourth lobe, and beyond this a 

 spine and then two very large spine-like plates, not branched, and still further a 

 gronj) of about five large s]>ine-like plates. Anal orifice between posterior ends of 

 cephalolateral grou])s of glands, rotmd, slightly broader than long. Perhaps a 

 distinct species. 



C. (tmericatia ditlers ))y having the median lobes trilobed, though rather obscurely, 

 aud very large spine-like plates branched at tips; there are also more glands in the 

 caudolateral groups.
