My. T. D. A. Cockerell on some Mexican Coccide. 51 
amply distinct. It is remarkable for its large size and the 
Y markings. 
(6) Orthezia insignis, Dougl, var. 
Vera Cruz. 
The specimens differ a little from those found in Jamaica, 
but there is nothing to separate them specifically from 
insignis. 
(7) Pulvinaria lutea, sp. n. 
Vera Cruz, on variegated Croton. 
@ (adult). On underside of leaves. Sacs about 10 millim. 
long and 4 broad, convex but depressed, of satiny texture, 
with nearly parallel sides. Colour bright lemon-yellow. The 
brown shrivelled female is largely overlapped by the ovisac, 
which is here plicate, with a tendency to be trifid. 
Substance of body (in caustic soda) yellow; margin with 
large, distinct, and numerous spines. Derm with numerous 
tubular glands. 
Legs reddish. Femur about one third longer than tibia ; 
tarsus a little more than one third length of tibia. Claw short 
and curved. ‘Trochanter with two equal strong bristles. 
Femur with a very stout large bristle at right angles to its 
surface, before its middle. Tn one specimen this bristle was 
observed to be accompanied by a smaller similar one. ‘Tibia 
with a few hairs and a long bristle at right angles to its 
surface at the distal end. ‘Three strong oblique bristles spring 
from the side of the tarsus. The tarsal knobbed hairs are 
very long and stout and distinctly knobbed. The digitules 
of the claw are immense, with very stout stalks, and broad 
large flattened knobs. Both digitules and tarsal hairs must 
be deciduous, as the first leg [ examined showed none. 
Fégg oval, reddish (in soda). 
Young larva has the claw longer and practically straight, 
with the usual digitules and knobbed hairs. ind end trun- 
cate, with a cleft in the manner of Lecanium, and a short 
bristle arising from each side of the cleft. 
The young exhibit the usual characters of the group—the 
anal cleft, the four lateral incisions, &c. The spines in the 
lateral incisions are short. The hairs along the margin are 
short, not very numerous, and show a tendency to be knobbed. 
The posterior cleft is open, and two bristles project from its 
centre. The shape of the young is elongate, with nearly 
parallel sides. Colour pale brown or whitish. The eyes, 
situated on the margin, are reddish brown. The dorsum is 
bluntly keeled.
