hunter: the coccida; oe Kansas. 
Found massed on oleander leaves, much more abundant on 
under side than upper side. Atchison, Kans. 
Aspidiotus SBSCuli Johns, sub. sp. solus sub. sp. nov. Plate VII, Pig, 30. 
Female scale circular, to 3 mm. in diameter, flat, dark in 
central part, dirty gray around margin. Texture of scale light; 
one side will adhere to the bark while the other side being loose 
will curl up over, scale translucent. Exuviaj laterad of the center, 
sometimes on margin, covered with light secretion, easily rubbed 
off showing light orange exuviae. Ventral scale almost invisible to 
the naked eye. 
The plates of the female agree in the main with ancyclus, the 
contour of the anal plate resembles the same species, notably the 
depressed second lobes. The scale presents differences which 
preclude a consideration of ancyclus. The scales are much scat- 
tered and are situated singly. Upon seven twigs averaging three 
inches in length, all chosen from the tree because they bore scales, 
the following numbers of scales appear on each in the order ex- 
amined: four, two, three, five, one, one, two. On the twig bearing 
three, two of them were about one-fourth inch apart, the others 
were more remote from each other. 
The male scale favors forhesi in color, but the description of 
Juglans-rcgicc in shape. 
Mature female. Light yellow, one pair of median lobes, notched 
midway of lateral margin, lobes in some converging, in others the 
inner line of lobe is straight or slightly divergent. Two pairs of 
chitinous processes on each side, club-shaped. From the pair just 
laterad of the median lobes there extend cephalad U-shaped 
openings in the bod}' wall. 
Plates prominent. Caudad of first pair of club-shaped processes 
is a plate generally forked, between first and second pair processes 
there are from none to three plates, caudad of second pair pro- 
cesses are one or two plates. 
There is a spine near lateral margin of lobe, a pair of spines be- 
tween the two pairs of processes, a pair of spines just laterad of 
second pair of processes, another pair one-third distance from lobe 
to penultimate segment, a single spine a like distance from the 
penultimate segment. 
Five groups of circumgenital glands, caudo-laterals 6 to 9, 
cephalo-laterals 9 to 14, anterior o to 2. Club organs around 
glands, in some cases obscuring the anterior group. 
From ten satisfactory mounts and many scales. On Jugtans 
nigra L. University campus. .
