Aulacaspis rosae Ckll., Bull. Bot. Dept. Jam., p. 259 (1896). 
Scale of female: Circular or irregular, snowy-white, sometimes 
with yellowish tinge, 2-3 mm. diam; exuviae sublateral; first larval 
skin naked showing the segmentation; second covered. 
Scale of male: 1.25—1.5 mm. in length; white and tri-carinated. 
Female: Body elongated; the ante-penultimate segment promi- 
nently lobed and bearing 8-10 gland-spines. Median lobes large, approxi- 
mate at base, serrulate, diverging, attached to body for entire length. 
Inner lobules of second, third and fourth lobes, rounded larger than the 
outer lobule. Fourth lobe nearly obsolete. There is a gland-spine laterad 
or each of the four lobes and 2-4 near penultimate segment, enlarging 
as they are further removed from the meson. On the dorsal surface 
the spines are situated as follows: a very small one on the median 
lobe, and one slightly larger on the outer lobule of the second, third 
and fourth lobes respectively, and one about three-fourths of distance 
to penultimate segment. The spines on the ventral surface are slightly 
mesad of the corresponding dorsal ones. Dorsal pores in three rows; 
second row represented by anterior group of 2-3; third row, anterior 
group, 4-5, posterior group, 5-6; fourth row, anterior, 4-6, posterior 
group, 6-8. Mesad of second and third lobes respectively, is an elon- 
gated pore appearing like a lobe. Anterior group of circumgenital 
gland-crifices distinet, rounded, 18-22; anterior lateral, 25-32; posterior 
lateral, 26-34. Lateral groups indistinctly separated, sometimes almost 
continuous. 
Remarks: Generaliy distributed over Ohio on rose-bushes, 
raspberries and blackberries. 
Genus HEMICHIONASPIS CkIl. 
in the members of this genus the median lobes are fused, 
and together form a dark-colored semi-circle. But one species 
has been reported, H. aspidistrae Sign. in which the seale of the 
female is brown and the median lobes are small and sunken in 
the pyeidium.
