Crypticerya, n. subg.uSimilar to Icerya

without the waxy tufts of subg. Crossotosoma.
Adapted for living under bark. Type, Icerya

Proticerya, n. subg.--Similar to Icerya
s. str., but adult with only 9-jointed
antennae. Ovisac large. No conspicuous
waxy tufts. Type, Icerya rileyi, n. sp.
Icerya rileyi, n. sp.u dull red, covered
with white and yellowish mealy powder,
a few small easily deciduous lateral waxy
tufts. Ovisac io mm. long, 5 broad, white
with a slight yellowish tinge, smooth, not
fluted, obscurely longitudinally grooved

differences are not specific, the antennae are
variable. Legs and antennae black. For

description is given at this time, as it is
hoped to describe and figure the various
stages from fresh material hereafter. The
insect will be very easily recognized by the
characters now cited, especially if reference
is also made to the descriptive notes of Prof.

Hab.--Las Cruces, N. M., common on
Mesquite (Prosopis) and rather rare on
Creosote bush (Larrea). It is attacked by
Laetilia and an apparently new species of
Coccinellidae. This interesting species was
to have been described by Dr. Riley had he
lived; in his opinion, it represented a valid
new genus. The ant, Dorymyrnex
yramicus Rog., attends it.
Aspidiotus prosopidis, n. sp.-- scale
about mm. diameter; slightly convex,
from circular to very broad pyriform,
slightly shining, pitch black; exuviae large,
uncovered, ridged black or slightly
greenish or brownish, central. The exuviae
are remarkably large for the size of the
scale. Removed from the bark the scales
leave a broad whitish ring with no black
ring.

scale oval, larger than that of the
white, with yellowish exuviae towards one
of the same’texture as those of the
extremely small, after boiling in soda
transparent, tinged with yellowish-brown,
circular in outline, not visibly segmented,
anterior end with a large rounded
protuberance such as is seen in A. ersonatus.
Mouth-parts well-developed. Skin of
anterior portion transversely reticulately
wrinkled. No grouped ventral glands.
Lobes extremely small, two pairs, median
rounded, nearly as far apart as the diameter
of one. Second lobes also roundedl but
broader and lower than the median, nearly
as far from them as the diameter of one.
A spine close to each lobe, and three on
the margin beyond, at long intervals.
Plates hardly visible. Anal orifice about
as far from base of median lobes as its
longer diameter.
A contains two long-oval embryos,
which are extraordinarily large, more than
half as long as the diameter of the ?. The
last joint of the antenna of the embryo is
as long or a little longer than the three
before it together.

numerously infesting the small twigs. Found by
Prof. Toumey about 4 miles west of Phoenix,
in Salt River Valley, Arizona, Sept. x895.
This singular little species,has the scale
completely enveloping the and so would
fall in Signoret’s subgenus Targionia. In
several characters it resembles A. bersonatus,
but it is very distinct from any species
described. It might have been thought
that the specimens were not adult, had not
matured embryos been found. It is found
on the leaves as well as the twigs.
Dactylopius pandani, n. sp.-- 3 ram.
long, x broad, pale yellowish brown. Legs
and antennae very pale yellowish brown.
Margin with stout cottony tufts as in 29. cirri.
Dorsum covered with white meal.
turns reddish on boiling in soda, but
gives no crimson color. It becomes almost
colorless, but the contained embryos remain
bright yellow. Antennae 8-jointed, joints
with whorls of hairs, joint unusually long,
even a little longer than 2; 2 subequal with
3 4 to 7 equal and shortest; 8 about as long
as I. Formula (18) (23) (4567), but itmight
almost as well be written (I823) (4567
Rostal loop reaching to level of base of
second pair of legs. Legs ordinary, tibia of
anterior legs about longer than tarsus of
middle legs only about 1/4 longer. Femur +
trochanter a little longer than tibia + tarsus.
Claw small. Digitules slender, those of claw
with conspicuous round knobs, those of tarsus
with very small knobs. Trochanter with a
long bristle. Posterior tubercles hardly
noticeable, each bearing a bristle only about
1/4 longer than those of the anal ring. Anal
ring with the usual 6 bristles. Eyes
prominent, elevated on a stout base. Six patches
of small spines o (...truncated)
