rather badly infested, causing malformation of the smaller

CHIONASPIS CORNI Cooley.

Chionaspis corni Cooley, Special Buil. Hatch Exp. Sta., p. 15 (1899). 
Chionaspis corni King, Can. Ent., xxxiv, p. 61 (1902). 
Scale of female: Length, 1.6—2mm. Somewhat irregular in 
shape, gradually broadened posteriorily, of rather delicate texture, 
white. The orange-yellow or brown exuviae are about .7 mm. long. 
Scale of male: Length, .6——.8mm.; the pale-yellow exuvia occu- 
pies about one-third of the moderately tri-carinate scale. 
Female: Median lobes fused for about one-half their length, then 
they diverge in an almost straight edge to the somewhat pointed apex; 
usually entire, short and broad. Inner lobule of second and third 
lobes rounded, entire and much larger than outer lobule. Gland-spines, 
excepting first, rather long and slender, arranged as follows: 1, 1, 1-2, 
1-2, 4-6. Second row of dorsal pores represented by anterior group of 
2-5: third row with 4-5 in anterior and 5-7 in posterior group; fourth 
row with 4-7 in anterior and 6-9 in posterior group. Median group of 
circumgenital gland-orifices, 9-16; anterior lateral, 17-28; posterior 
lateral, 10-20. 
Remarks: This species was first collected in Ohio, at San- 
dusky on Cornus amomum, by Prof. Herbert Osborn and later 
by the author. The smaller branches were encrusted with the 
seales.

Ch. euonymi Kuwana, Pr. Cal. Ac. Sci., (3) iii, p. 75 (1902). 
Scale of female: Length about 2mm., decidedly broadened pos- 
teriorly, convex, rather thick and firm in texture, dark grayish-brown. 
Ventral scale entirely developed, attached along the sides but free 
at the posterior extremity. 
Scale of male: Length, 1.5 mm., white, tricarinated with a yellow 
exuvia. 
Female: Median lobes, and lobules of second and third lobes, 
serrulate and pointed. The lobes are far apart, and the lobules are 
distinctly parted to the base, slightly chitinized on the margins, the 
inner always the larger. Gland-spines rather short, and arranged as 
foilows: 1, 1-2, 1-2, 1-3, 1-4. On the ventral margin the spines are 
short and inconspicuous, situated near each group of gland-spines 
excepting the fifth. The dorsal spines are longer and situated mesad 
of the corresponding ventral spine. Dorsal pores rather numerous and
