sented so as to show the limits observed in the material examined.
When many examples of a species have been studied, the limits recorded
should cover satisfactorily the range of variation expected in that
species. On the other hand, where only a few specimens have been
studied, it may be expected that the quantitative limits here presented
will be widened as additional material is examined.
The drawings used in this paper present structural details of use
for the recognition of species. Divided drawings show the dorsal
surface on the right, and the ventral on the left. ~ Minute pores, sub-
marginal setae, and tubular ducts usually are omitted from the outline
figures. Where the enlargement of a structure is not given in the
explanation of figures, it lies within the range of 1,100 to 1,500 times.
The photographs are enlarged approximately 10 times.
SPECIES GROUPS
The genus Asferolecanium comprises an extremely homogeneous
array of species. Nevertheless, some species fall into definite groups,
and others stand alone. Structures of the nymphal and adult males
do not appear suggestive of grouping within the genus, and those of
the second-stage insects and third-stage males seem indicative only of
broad specific relationships. T herefore, species segregation is based
on structures of the adult females and larvae. In some cases groups
definable on the basis of morphological characters are also set apart
by indicated host preferences or geographical distribution. Since a
natural grouping usually is not followed in the keys, and since only
the most closely related species are discussed and contrasted in the
descriptions, it seems desirable to define these groups, and to point out
the zoogeographical regions inhabited by them. Claim is not made
for complete accuracy in these assignments because additional collect-
ing and study are necessary before the relationships and the native
habitats of some species can be known with even approximate cer-
tainty. The order in which the groups are given is arbitrary. Only
species studied by the writer are included and, with two exceptions,
the distribution shown is based only on records ‘listed in this paper.
Group I (abiectum, acutulum, amboinae, bambusae, bambusicola,
brunetae, captiosum, caudatum, ‘ceriferum ceriferum, ’ chinae, circu-
lare, coronatum., delicatum, disiunctum, elongatum, exiguum, florum,
fusum, gemmae, hemis phaericum, largum, longulum, longum, masuti,
miliaris miliaris, miliaris robustum, mimicum, minusculum, min-
utum, notabile, oblongum, ordinarium, parvum, penicillatum, pro-
boscidis, pseudolanceolatum, pseudomiliaris, pusillum, radiatum,
mubrocomatum, sasae, scirrosis, simplex, solenophoroides, sparus, sub-
dolum, udagamae, vulgare).—Known to occur only on Bambuseae.
The natural distribution of some of these species must be inferred
since some of them are now established in each of the six major
zoogeographical regions. Regardless of their present-day distribu-
tion, however, all of them probably are indigenous to the Oriental
Region.
Adult female characterized by the presence of dorsal tubes (restricted to
this group), an interrupted row of submarginal setae, and a beak without
setae. Larva (with one exception) characterized by absence of a minute seta
close to each of the posterior 2 or 3 pairs of marginal 8-shaped pores; sixth
antennal segment having 2 long, 2 stout, and 2 or 3 fairly stout setae; coxa
usually with 4 setae, femur usually with 3, and tarsus usually with 3.
THE SCALE INSECT GENUS ASTEROLECANIUM g
Group IT (boliviae, bondari, degeneratum, difficile, distinctum, gil-
vum, hilli, inlabefactum, inusitatum, oraniae, pallidum, palmae,
phoenicis, pinnangae, sabalis, simile, singulare, spectabile, trunc-
atum, unicum, urichi) —Known to occur only on Palmae. Repre-
sentatives of the group are found in the Neotropical, Ethiopian,
Palearctic, Oriental, and Australian Regions. Although the major-
ity of species appear indigenous to the Neotropical Region, several
are probably native to the Oriental, and one may be indigenous to
the Australian Region. The native homes of the species known from
the Ethiopian and Palearctic Regions are uncertain.
Adult female characterized by body being longer than wide, usually with
marginal row of 8-shaped pores interrupted, or terminating at a considerable
distance from bases of apical setae; anal opening simple, circular, without anal
ring or setae, or anal opening circular or elliptical with anal ring modified
into a plate or into 2 collars, without any setae or with 2 or 4; spiracular
atrium usually enlarged and containing pores. Larva usually characterized by
presence of a minute seta near each pore of the posterior 3 pairs of marginal
8-shaped pores, terminal antennal segment with 3 long setae, femur with 1
seta, and tarsus with 2 setae.
Group III (adjunctum, bellum, castaneae, horishae, ilicicola, ja-
ponicum, luteolum, minus, nitidum, pasaniae, perplexum, quercicola,
repugnans, roboris, semisepultum, skanianadé, suishae, variabile,
variolosum, viennae)—Known to occur only on Fagaceae. Some of
these species are now found in each of the six major zoogeographical
regions. Originally they were probably restricted to the Palearctic
Region, or to this and the Oriental Region.
Adult female characterized by body usually being somewhat circular; 8 or
fewer pairs of setae on apex of abdomen; anal opening ventral, fairly close
to body margin; presence of multilocular pores; margin of anal opening with
2 setae or with none. Larva with anterior margin of body provided with 2
pairs of setae; first and fourth antennal segments each with 1 seta, fifth with
none, sixth with 2 long, 2 stout, usually 2 fairly stout, and 2 slender setae;
coxa with 3, femur with 1, tarsus with 2 setae; 3 or fewer pairs of setae on
apex of abdomen, margin of anal opening or anal ring without any or with
2 setae.
Group IV (algeriense, arabidis, fimbriatum, launeae, nevadense,
stentae, zanthenes).—All these species are probably indigenous to
the Palearctic Region, although arabidis apparently has been intro-
duced into and is now established in the Nearctic Region, and
stentae 1s known to occur only in the Ethiopian Region.
Adult female characterized by a double or triple row of marginal 8-sShaped
pores; submarginal 8-shaped pores in a row 2 to 4 or 6 pores wide; a marginal
row of disk pores dorsad and ventrad of 8-shaped pores; 6 pairs of setae on
apex of abdomen, absence of elongate sclerotized areas from ventral surface
of apex of abdomen. Larva with first antennal segment provided with 2
setae, fourth with 1, fifth with 1, sixth with 2 long, 2 stout, and 3 fairly stout
setae; coxa with 4, femur with 3, and tarsus with 3 setae; less than 9 pairs
of submarginal 8-shaped pores.
Group V (brachylenae, thespesiae)—Although brachylenae 1s
known to occur only in the Ethiopian and thespestae in the Oriental
Region, they are so similar structurally that their natural distribu-
tion may include only one region. On the basis of their relationship
to other members of the genus, they appear indigenous to the Oriental
Region.
Adult female characterized by a double row of marginal and submarginal
8-shaped pores, a marginal row of disk pores dorsad and yventrad of 8-shaped
pores, 6 pairs of setae on apex of abdomen, and 2 elongate sclerotized areas
10 MISC. PUBLICATION 424, U. 8S. DEPT. OF AGRICULTURE
placed ventrally on apex of abdomen. Larva having first antennal segment
with 2 setae, fourth with 1, fifth with 1, sixth with 2 long, 2 stout, 3 fairly
stout, and 2 slender setae; coxa with 4, femur with 3, tarsus with 3 setae; 9
pairs of submarginal 8-shaped pores.
Group VI (agavis, cristatum, grandiculum, puteanum, sanbernar-
dense, townsendi, viridulum).—Species of this group are found in the
Nearctic and Neotropical Regions. Although they appear indigenous
to both regions, they may be native only to the Neotropical, because
certain members of the group appear only in, or appear to be spread-
ing from, the lower limits of the Nearctic Region, thus suggesting a
gradual extension of an original Neotropical distribution.
Adult female characterized by row of marginal quinquelocular pores usually
being interrupted, or terminating at a considerable distance from _ posterior
marginal 8-shaped pores; by the presence usually of a marginal row of disk pores
dorsad of 8-shaped pores; by the occurrence of 5 pairs of setae on apex of
abdomen; and by the absence of a rectangular sclerotized area or 2 elongate
sclerotized areas from ventral surface of apex of abdomen. Larva with first
antennal segment provided with 2 setae, fourth with 1, fifth with none, sixth
with 2 long, 2 stout, 3 fairly stout, and 2 slender setae; coxa with 4, femur
with 3, tarsus with 3 setae.
Group VIT (hakeae, quadrisetosum, subventruosum, ventruosum) —
All species of this group are found in, and doubtless are indigenous to,
the Australian Region.
Adult female characterized by a double row of marginal 8-shaped pores, a
marginal row of disk pores usually dorsad and ventrad of 8-shaped pores, a
complete row of marginal quinquelocular pores terminating less than 7 8-shaped
pores from posterior marginal 8-shaped pores, 4 pairs of setae on apex of abdomen,
absence of a rectangular or 2 elongate sclerotized areas from ventral surface
of apex of abdomen. Larva characterized by coxa with 3 setae, femur with 2,
and tarsus with 2 setae.
Group VIII (epacridis, inconspicuum, lacrimula, multiporum,
stypheliae, transversum).—All species of this group are found in, and
appear native to, the Australian Region.
Adult female usually characterized by a single row of marginal 8-shaped pores, a
complete row of marginal quinquelocular pores terminating at or near posterior
marginal 8-shaped pores, absence of a well defined marginal or ventral sub-
marginal row of disk pores; a rectangular or 2 elongate sclerotized areas, or
gradations between the two, placed ventrally on apex of abdomen; an anal ring
with 6 setae and usually with pores, Larva usually characterized by first antennal
segment with 2 setae. fourth with 1, fifth with 1, sixth with 2 long, 2 stout,
3 fairly stout, and 2 slender setae; coxa with 4 setae, femur with 2, tarsus with
2 setae.
Group IX (victoriae, vitreum).—Both these species are found in,
and appear indigenous to, the Australian Region.
Adult female characterized by a single row of marginal 8-shaped pores, a
complete row of marginal quinquelocular pores terminating near posterior
marginal 8-shaped pores, a cylindrical anal tube, a circular anal ring without
pores but with 2 or 4 setae about 2u long. Larva having first antennal seg-
ment with 1 seta, fourth with 1, fifth with 1, sixth with 2 long, 2 stout, 3
fairly stout, and 2 slender setae; coxa with 4 setae, femur with 2, and tarsus
with 2 setae.
Group X (corallinum, javae, litseae, machili, psychotriae, stria-
tum).—These species occur within, and appear indigenous to, the
Oriental Region, though J/itseae has also been reported from the
lower part of the Manchurian Subregion of the Palearctic Region.
Adult female characterized by a single row of marginal 8-shaped pores, a
complete row of quinquelocular pores terminating at or posterior to posterior

marginal 8-shaped pores, a submarginal row of disk pores (usually), and a
rectangular sclerotized area or 2 elongated sclerotized areas on ventral surface
of apex of abdomen. Larva (only those of javae and striatum available)
having first antennal segment with 1 seta, fifth with 1, sixth with 2 stout and
3 fairly stout setae; coxa with 4 setae, femur with 2, and tarsus with 3 setae.
Group XI (coffeae, conspicuum, pustulans).—The species coffeae
and conspicuum are known only from the Ethiopian Region, but
pustulans is well disseminated, being found in each of the six major
zoogeographical regions. These insects are so similar morphologically
to various other species believed to be native to the Oriental Region
that there is definite question as to their distributional origin. The
relationship of these species to those included in group X is evident,
and additional species and further study may show that these two
groups should be consolidated.
Adult female characterized by a single row of marginal 8-shaped pores, a
row of marginal quinquelocular pores terminating at or near posterior marginal
8-shaped pores, a ventral marginal row of disk pores, a rectangular sclerotized
area or 2 elongate sclerotized areas on ventral surface of apex of abdomen.
Larva having first antennal segment with 2 setae, fifth with 1, sixth with 2
long and 2 stout setae; coxa usually with 4 setae, femur with 3, and tarsus with
3 setae.
Group XII (gutta).—This species is found in, and may be in-
digenous to, the Oriental Region.
Adult female and larva characterized by unusual shape of 8-shaped pores,
which are as wide as long, with the halves closely appressed; by apex of
abdomen being simply invaginated with anal ring at base of invagination, anal
opening and anal tube not differentiated from surrounding derm.
Certain species do not fit properly in any of the groups defined
above, although a few do resemble the species included in one or
another of the outlined groups. The species involved are the follow-
ing: acaciae, found in and indigenous to the Australian Region;
borboniae, found in the Ethiopian Region, native habitat uncertain;
borneense, garciniae, sumatrae, found in the Oriental Region, indige-
nous to the Palearctic or Oriental region, possibly belonging in one
group ; brevispinum, found in and indigenous to the Ethiopian Region;
epidendri, found in the Palearctic and Nearctic Regions (in green-
houses), and in the Oriental and Neotropical Regions, probably in-
digenous to the Neotropical Region, resembling species of Group VI;
euphorbiae, found in the Ethiopian Region, native habitat uncertain,
resembling species of Group VI; ewryopis, occurring in and indigenous
to the Ethiopian Region; fagellariae, found in the Oriental Region,
native habitat uncertain; 7ngae, known from and probably indigenous
to the Neotropical Region, resembling species of Group VI; medium,
found in and indigenous to the Australian Region, resembling species
of Group IX; petrophilae, occurring in and probably native to the
Australian Region; qguaesitum, found in and probably indigenous to
the Neotropical Region, resembling species of Group VI; tokyonis,
found in the Oriental and Palearctic Regions, probably indigenous to
the Palearctic Region; wagulatum, found in the Oriental Region and
indigenous to it or to the Australian Region, resembling species of
Group VIII. |
Type material of the new species described in this paper is included
in the National Collection of Coccidae and, in some cases, in the collee-
tion of the individual or institution furnishing specimens.

1925, paratypes (1 female and 8 larvae, all available material, mounted).
This species resembles miliaris but is larger, and the marginal
8-shaped pores, which are longer in proportion to their width than
those of miliaris, terminate farther from the bases of the apical setae.
In the shape of the marginal 8-shaped pores, as well as in other charac-
ters, it resembles captioswm, but differs from that species in having
four, instead of three, pairs of setae on the apex of the abdomen.
8 Axes of pores are in respect to body margin at point where pores are situated.
® Roman numerals refer to antennal segments.

38 MISC. PUBLICATION 424, U. S. DEPT. OF AGRICULTURE
Data—Redescribed from two mounted females, Maskell Collection
No. 423, U. S. National Museum Catalogue No. 40359, holotype and
paratype, concerning which Morrison and Morrison (73, p. 4) said,
“obtained from the Maskell collection, and, on the basis of his descrip-
tive notes, collected at Sydney, New South Wales, on Acacia species.
This material was a part of his lot No. 423, and was regarded by him
as the species ventruosum”; unmounted material, three mounted fe-
males, and two mounted larvae, Maskell, Cockerell Collection.
The diameter of the specimens is 1.25— 1.5 mm. instead of “0. 7,” and
the number of rows of multilocular pores is four complete and one or
two interrupted instead of “apparently two,” as given in the original
description. The authors stated, “apparently without quinquelocular
disk pores, replaced at spiracles and along margin by small size multi-
locular disk pores, mostly with 10 loculi, but somewhat. variable”
(73, p. 4). In1 of the specimens examined the majority of these pores
have 5 loculi, and in the other specimens the majority have 6 to 8 loculi,
but there are some pores in all specimens with 5 to 10 loculi.
In adults of this species the interapical setae are situated on the ven-
tral surface close to the ventral setae and appear to be more closely
associated with the latter than with the apical. Moreover, what is
believed to be the posterior pair of submarginal setae is sometimes so
close to the ventral setae that it actually appears to be a ventral pair.
Thus the general appearance is, as shown in figure 2, A, of a pair of
apical setae and four pairs of ventral setae rather than an apical, an
interapical, two ventral, and a submarginal pair.

sp. ?, Ariz., D. W. Coquillett, November 8, 1893; 10 females and 7 lar-
vae on Agave sp., El Paso, Tex., J. N. Rose, May 18, 1908; 16 females

number of dorsal 8-shaped pores, and from puteanuwm by a smaller
number of marginal quinquelocular pores, and the presence of a mar-
ginal row of disk pores.

setae 28-30 uw long, and an inner row of 6 and an outer one of 14 pores; ventral
surface of apex slightly sclerotized near margin.
Data.—Redescribed from unmounted material, 1 mounted female,
and 22 mounted larvae on Cistus salviaefolius, Azazga, Kabylie, Al-
geria, A. Balachowsky, December 13, 1936.
Material at hand has been placed as al/geriense on the basis of com-
parison with Newstead’s description. Although Newstead described
stages which he called “larva” and “ ? second stage,” both descriptions
apparently referred to the larval stage. He stated that the second
and fourth segments of the antenna had each a single hair, and the
sixth one long and two shorter; the second segment has two long setae,
and the sixth more than one long and two short setae.
Although listed as a synonym of fimbriatuwm by Lindinger in 1912
(61, p. 360), algeriense is not a synonym of fimbriatum or of arabidis,
to which it is more closely related. The adult female is difficult to
differentiate from arabidis, but the dorsal 8-shaped pores are more
numerous than in most specimens of that species, and those between
the median groups and the body margin tend to be larger than those
in the same area in avabidis; the marginal quinquelocular pores are
interrupted for a slightly greater distance at the anterior end and
terminate a little farther from the apical setae than in aradidis.
Larvae of the two species differ distinctly, algeriense having one and
arabidis two pores near each spiracle.

ASTEROLECANIUM ARABIDIS (Signoret)
(Wig, 6, AT; pl. 2, #, A)
Described by Signoret in 1876 (89, p. 608) as Planchonia arabidis,
from specimens received from Lichtenstein. Although Signoret listed
‘ the species as “Planchonia arabidis Licht. mss.,” there is no indication
il that Lichtenstein was responsible for any part of the description.
Consequently the species is credited to Signoret.
3 Four names are here suppressed as synonyms of arabidis. Plan-
chonia hederae, described by Lichtenstein in 1880 (58, pp. xvlv—alvi)
on Hedera helix from Montpellier, is placed as a synonym because
! specimens presumed to be type material of hederae are specifically
identical with avabidis. In 1882 (59, p. leav) Lichtenstein gave the
. name Planchonia valloti to specimens which he had not seen, that had
i been described briefly, but not named, by Vallot, in 1838 (99, pp. 50-51).
Although Vallot’s material, found on ivy at Dijon, or other material
from this source, is not available, it seems likely that his specimens
ml belonged to arabidis, the species found commonly on ivy in Europe.
" Vallot did not indicate whether he removed any insects from the ivy,
| and the specimens treated by him and Lichtenstein probably are not
ml | extant. The name vailoti was listed as a synonym of hederae by
Fernald in 1903 (32, p. 51) and of fimbriatum by Lindinger in 1912
(61, p. 3875).
A. massalongianum was described by Targioni-Tozzetti in 1892
(98, pp. 295-298, 312) on. Hedera from Italy. Type material of the
| species is not available, but other specimens on Hedera from Italy
represent arabidis. Moreover, from the original description of mas-
i salongianum it seems certain that this name is synonymous with
| arabidis. It was given as a synonym of hederae by Fernald in 1903
mi (32, p. 51), and as a synonym of fimbriatum by Lindinger in 1912 (61,
i p. 175) and by Leonardi in 1920 (57, p. 247).
Al In 1893 Douglas described Pollina thesii, on Thesium humifusum
ah from the Isle of Purbeck (29, pp. 55-57). A mounted specimen from
| type material of theszi is the same as arabidis, and as a consequence the
THE SCALE INSECT GENUS ASTEROLECANIUM 45

Lindinger in 1912 (61, p. 360).

variation both in arrangement and number of multilocular pores. ‘The
same condition is found in stentae, a species closely related to arabidis,

studied, in other closely related forms such as /auneae and fimbriatum.
ASTEROLECANIUM BAMBUSAE (Boisduval)
(Fig. 6, J-O ; fig. 7, A-G; pl. 2, F, G)
Described by Boisduval in 1869, as Chermes bambusae, on Bambusa
arundinacea and distorta from the garden of Hamma, Alger, Algeria
(9, pp. 261-262) ; redescribed by Signoret in 1870 (88, pp. 280-281).
Signoret indirectly disclosed the source of his material of bambusae
in the following statement contained in his description of méliaris,
which follows that of bambusae: “Cette espéce, comme la précédente,
se trouve en quantité quelquefois considérable sur les divers bambous
des Indes, Bambusa distorta, arundinacea, stricta, et elle nous a été
donnée par M. Boisduval et par M. Riviére, qui nous en a fait venir
obliigeamment du Jardin d’Acclimatation du. Hamma (Algérie).”
Thus it is reasonable to assume that his specimens of bambusae were
received from Boisduval or Riviére, and as such represent type
material. 3
Type specimens of bambusae var. bambusulae, described by Cock-
erell in 1897 (20, p. 590), on bamboo from Grenada, are identical with
bambusae ; consequently the varietal name is suppressed.

nal row about 5 pores wide posterior to posterior spiracles, and a few in median
area of abdomen ; submarginal 8-shaped pores usually in a single row terminating
about midway between posterior row of multilocular pores and the posterior pair
of marginal 8-Shaped pores, aS numerous as marginal 8-shaped pores; 7 pairs of
submarginal setae, posterior to anterior spiracles, the posterior pair near the
posterior or penultimate pair of marginal 8-shaped pores; 1 pair of setae in each

1913, from E. E. Green, possibly type; 11 females on bamboo, New
Orleans, La., E. R. Sasscer, March 9, 1919; 6 females on Bambusa sp.,
Taihoku, Taiwan (Formosa), R. Takahashi, January 1928, possibly
type material of tuberculatum,; 2 females on Phyllostachys bambu-
soides, Keijo, Chosen, S. Nakayama, November 3, 1928; 1 female and 2
larvae on bamboo, Ocean Springs, Miss., H. Gladney, April 12, 1929;
8 females and 2 larvae on bamboo, Japan, intercepted at Philadelphia,
Pa., A. B. Wells, December 19, 1932.
In the paper containing the original description of bambusicola
Kuwana (545, p. 147) published the following note:
With regard to this species, Prof. Green has given me the following remark:
“This resembles A. bambusae Bdv. superficially, but differs from that species
in several important particulars. In the first place the marginal fringe is of
a bright pink color. I note that the marginal series of paired glands is single
on the abdomen but irregularly double on the thorax. There are numerous simple
circular glands immediately within the paired series, and bands of similar pores
connect the stigmata with the margin. There are no supplementary paired
glands on the dorsum.” The writer should state here that he has not been able
to recognize the double series of paired glands on the thorax, mentioned by
Prof. Green.
As shown by Kuwana, there is no indication of a double series of
marginal 8-shaped pores on the thorax or elsewhere on the margin.
Green might have been dealing with another species, or notes concern-
ing two species might have become confused.
In the description of tuberculatum Takahashi mentioned a “trans-
verse tubercular ridge across about the middle of the scale.” The
ridge is characteristic of the test, and appears as two tiny humps
immediately anterior to an imaginary transverse median line.

convex, with the caudal extremity produced into a narrow upturned process.
The colour is bright yellow and somewhat transparent, except at the anterior end
which is bright brown in the few specimens at hand. probably owing to the
THE SCALE INSECT GENUS ASTEROLECANIUM 57
presence of the shrivelled female body. Of the eight specimens in this collection
five of the tests are entirely naked. The other three show the presence of
long large curved glassy filaments (fig. 188), which were apparently equally long

stout ; antennal bases one-third length of antenna apart; beak setae, 2 pairs apical,
1 pair basal; spiracle with 1 trilocular pore; leg setae, coxa 4, femur 1 on inner

Data.—Redescribed from 2 mounted intact and 2 mounted fragmen-
tary females, and 23 mounted larvae on veld-bush, Ceres, Cape Prov-
ince, South Africa, C. P. L. 1898, Brain No. 21, type and paratypes.
Adults of this species are unusual in having the row of marginal
8-shaped pores indefinite owing to the distance between these, to their
position, and to the proximity of the dorsal pores to the marginal. The
larvae are unusual in having only three pairs of minute submarginal
8-shaped pores. The species resembles ewryop?s in having invaginated
8-shaped pores and a poorly defined row of marginal 8-shaped pores.

Pata—Described from unmounted and the following mounited
material collected on Castanea from China (all unmounted and mounted
specimens, except holotype, are paratypes) : Two females and 11 larvae
on C. henryi, Tientai Shan, Chekiang, R. C. Ching, May 5-18, 1924,
U.S. N. H.; 1 female on C. sequinéi, near Siachu, Chekiang, R. C. Ching,
May 22-24, 1924, U. S. N. H.; the following material intercepted at
Washington, D. C., in January 1932, January 1934, January and
February 1935, and January and April 1936 by the Division of Foreign
Plant Quarantines, Bureau of Entomology and Plant Quarantine:
7 females on C. mollissima, Ysi Hong, holotype and paratypes; 54
females and 3 larvae on C. mollissima, C. sequinu, or Castanea sp.,
from near Nanking, Kiangsu; near Hangchow, Chekiang; Kiangsi.
This species is closely related to pasaniae, but differs from it in
several particulars. Tests of castaneae are ovoid or circular and
distinctly smaller than the one available authentic test of pasaniae,
which is distinctly longer than wide. The most obvious microscopic
difference between the two is the arrangement of the multilocular pores,
which in castaneae are represented only by four complete rows and in
THE SCALE INSECT GENUS ASTEROLECANIUM 61
pasaniae by four complete and four interrupted rows. There are
also 20 to 30 multilocular pores in castanege, and 36 in pasaniae.
Another obvious difference is the greater number of marginal quin-
quelocular pores in proportion to the marginal 8-shaped pores in
castaneae, and the fact that the row extends as far, or nearly as far,
posteriorly as the marginal 8-shaped pores. Furthermore, the habits
of the two are different, castaneae being known only from bark and
pasaniae from leaves.
ASTEROLECANIUM CAUDATUM Green

two-thirds of test parallel or indented by growth against hairs of leaf, posterior
third usually strongly narrowed and produced, but sometimes tapering rather
gradually from broader area to tip; 1.4-35 mm. long, 0.40.75 wide; slightly raised
dorsally, with a faint longitudinal median carina, flat ventrally; greenish or
very pale clear yellow, transparent, thin, slightly punctate; marginal filaments
colorless, or whitish to very pale yellowish, usually absent from posterior end
and rather sparse to fairly numerous elsewhere; sometimes with 1—20 whitish
dorsal filaments placed at varying intervals in submarginal area, longer than
marginal; circular larval exit in margin.
Adult female—Shape similar to that of test, parasitized specimens apparently
not strongly narrowed ; 1.4-2.75 mm. long, 0.40.65 wide.
Margin: 8-shaped pores in a single row, the posterior pair of pores usually
around four times the length of apical seta from setal bases and penultimate
pair of pores at posterior third, or about six times the length of apical seta
from setal bases; if posterior third is strongly narrowed, the row sometimes
terminates at posterior third; if specimens taper rather gradually, the pores
terminate about twice length of apical seta from bases of setae, several of the
pores posteriorly being closer together: the spaces between the pores range
normally from more than one to three or four times a pore’s length, but some-
times there are long areas without pores, the latter condition probably being
due to growth against hairs on the leaf; individual pores measuring 7-8 u
long and 4 wide.

long and 6-8 wide; minute 8-shaped and disk pores rather sparse; tubular ducts
32 uw long; dorsal tubes present.

2 anterior to mouth parts, 1 each side of, and 2 anterior to, genital opening,
and usually a few in lateral area of abdomen arranged in 2-7 short transverse
rews: submarginal 8-shaped pores in a single row terminating near genital
opening, spaces between pores about equal to twice the length of a marginal
8-shaped pore; 4 pairs of submarginal setae near posterior end of abdomen,
the posterior pair about midway between genital opening and apical setae; 1
pair of setae posterior and 1 pair anterior to genital opening.
Apex of abdomen: Notch present; lobes rarely indicated; setae, apical 60-64
w long, interapical 12 w long, inner ventral 7-8 w long, outer ventral 8 uw long:
anal ring with 6 setae 32-36 uw long, and with an inner row of 6 and an outer
row of 14 pores, divided on dorsal side and tending toward division on ventral.
Second stage—Elongate, slender, tapering gradually from anterior third to
posterior tip; margin with 8-shaped pores once or twice a pore’s length apart,
the row terminating three times a pore’s length from bases of apical setae;
available specimens poor and characters on dorsal surface indeterminable;
ventral surface with 1 or 2 quinquelocular pores outside spiracle, minute char-
acters indeterminable; apex of abdomen as in adult but apical setae broken,
and other setae one-fourth shorter.

The following statement occurs in the original description of cauda-
tum (49, p. 215):
Margin of body with a series of rather large paired pores at intervals of ap-
proximately four times their own longer diameter; with an irregular’ sub-
marginal series of very much smaller paired pores. The paired pores are
inconspicuous and difficult to demonstrate.
Actually, the smaller paired pores are the marginal, and the larger
pores are in the submarginal area of the dorsal surface. The marginal
8-shaped pores often occur at varying intervals. The dropping out of
pores at various points and the variability of the terminating point
of the 8-shaped pores probably are due to growth against hairs or
veins of the leaves.
The species is closely related to pseudomiliaris, but as a rule is
much larger, being 1.4-2.75 mm. long instead-of 0.7-1.2; the marginal
8-shaped pores are usually at least twice a pore’s length apart and they
terminate around four times the length of an apical seta from the
bases of apical setae. Asterolecanium caudatum also has 3 to 6 instead
of 8 to 14 quinquelocular pores in each spiracular pore band.
ASTEROLECANIUM CERIFERUM variety CERIFERUM Green
(Fig. 18, G-M; pl. 8, P)
Described in 1909 (42, pp. 324-325).
Habit— ‘On leaves of a species of bamboo, the insects resting in shallow
pits on the under surface of the leaf, these hollows appearing on the upper
Surface as raised orange-coloured patches bearing ridge-like rows of hyper-
trophied cuticular cells.”
Test of female—‘Test of adult female elongate, narrow: lateral margins
approximately parallel, extremities rounded. Dorsum moderately convex, the
posterior third depressed and slightly concave; sides and front almost per-
pendicular, slightly sloping inwards, demarked from the dorsum by the angular
marginal line; posterior extremity free, the under parts sloping sharply inwards
so that, in profile (fig. 4), it appears to be sharply pointed. Ventral surface
convex, owing to a marked depression in the leaf beneath the insect. Margin
with straight stout glassy colourless filaments. rather widely spaced, longest at
the two extremities. Sides thickly coated with opaque, white, mealy secretion,
which extends slightly over the margin, concealing the bases of the glassy fila-
ments. Colour, during life, pale lemon yellow, darkening afterwards to ochreous.
Length 15 mm. Breadth 0.5 mm.” (42, p. 324.)

row of quinquelocular pores; 8-shaped pores 5 uw long: and 4 wide, scattered on
anterior half of body and concentrated between mouth parts and posterior

row on posterior half of body, terminating at the posterior pair of marginal
8-shaped pores and aS numerous as corresponding marginal 8-shaped pores,

THE SCALE INSECT GENUS ASTEROLECANIUM 65
Data.—Redescribed from one test, two mounted females, one mounted
second-stage specimen, and one mounted third-stage male on bamboo,
Hewaheta, Ceylon, E. E. Green, March 1910.
’ The test available for study is in such condition that little of value
can be added to Green’s excellent description, but it should be noted
that the sides, though nearly perpendicular, curve from the dorsum
rather than being demarked by an “angular marginal line.”
The species is unusual morphologically. The presence of quinque-
locular pores on each side of the marginal 8-shaped pores has not
been observed elsewhere in the genus and the presence of relatively
large 8-shaped pores on the ventral surface has been observed rarely.
Green associated the 8-shaped pores with the dorsal surface. In all
adult females at hand, however, there are no 8-shaped pores on the
dorsal surface although they do occur on the ventral surface. Green
stated (42, p. 324), “anal rig apparently hairless, at the base of a
remarkable funnel-shaped chitinous tube.” The ring has two setae,
however.

Data—Redescribed from unmounted material, three mounted fe-
males, and six mounted larvae on Coffea sp., Kenya, Africa, R. H. Le
Pelley, March 1933, from E. E. Green.
Both Laing (56, p. 467) and James (53, p. 421) have pointed out
that the filaments of the tests of this species are distinctly pinkish
instead of golden yellow as stated by Newstead. In some tests at
hand, all of which are dry, the filaments are the same color as the test,
while in others they are distinctly pinkish.
Newstead stated (76, p. 161), “Margin with two rows of figure-of-8
spinnerets and also a number of others arranged irregularly along the
submarginal area; first marginal row placed closely together; second
marginal row widely separated.” There is only one marginal row of
8-shaped pores, the “second marginal row” of Newstead being on the
dorsal surface. In the antennae of the larva, according to James
(53, p. 424), “eight joints can be distinguished in the majority of speci-
mens.” The specimens at hand, however, have the antennae six-seg-
mented. Eight antennal segments have not been found in any species
of this genus.

THE SCALE INSECT GENUS ASTEROLECANIUM 71
The filaments of available tests are whitish or yellowish instead of
reddish, as stated by Brain (72, p. 112).
This species is more closely related to coffeae than to other known
species. Both are unusual in having what appears to be an interme-
diate ventral seta unaccompanied by an outer ventral seta.

Data—Redescribed from unmounted material and the following
mounted specimens: Two females, two second-stage specimens, and
three larvae on Dendrocalamus giganteus, Peradeniya, Ceylon, E. E.
Green, January 1902, type material; five females and three larvae
on bamboo, Peradeniya, Ceylon, C. L. Marlatt, January 18, 1902, and
five females and one larva on bamboo, Royal Botanic Garden, Pera-
deniya, Ceylon, R. S. Woglum, October 1910.
Green (42, p. 327) said, “Posterior extremity without caudal setae,
but with two small marginal spines on each side.” The larger of the
two small setae is considered as apical even though it is small. Green
did not mention the small seta on the ventral surface close to the
median line. Because of its position in the larva, there is some ques-
tion as to whether the seta here called outer ventral is correctly labeled.
From its position in other stages, and from the condition observed in
the species most closely related to coronatum, however, it seems likely
that this seta does actually represent the outer ventral rather than the
interapical. This is the only known species of the genus in which
multilocular (enlarged quinquelocular) pores occur only anterior to
the genital opening.
The “male puparium” described and figured by Green probably is
an adult female. All specimens mounted from this type of test have
been females, no males having been found in the material at hand.
Some adult females have the same shape as second-stage specimens,
there being a great deal of variation in the extent. to which the posterior
end is narrowed and produced.

Data—Redescribed from the following mounted paratype material
collected by G. F. Ferris in Lower California: One female on Solanum
hindnanian, East of Rosario; 1 female and 6 larvae on Jatropha
canescens, San Antonio, 1919; 2 females on Celosia floribunda, San
Bartolo, July 17, 1919; and 2 females on Heteromeles arbutifolia, La
Laguna, August 1919.
This species is closely related to townsendi, but differs from it in
being much smaller, in having an interrupted row of marginal quin-
quelocular pores, 20 to 27 instead of 35 to 55 quinquelocular pores in
each spiracular band, 88 to 98 instead of about 271 multilocular pores,
and fewer submarginal 8-shaped pores.
In the specimens at hand there is no indication of the small, densely
sclerotized area outside the outer ventral seta shown in the illustration
accompanying the original description (33, p. 73), and the inner ventral
seta is not shown on that illustration. ‘Tests examined by the writer
were too poor to permit a complete redescription.

This species appears to be a degenerate form closely resembling
urichi, simile, and difficile. It differs from wrché in having multi-
locular pores, and apical setae the same length as the ring setae; from
simile in having marginal 8-shaped pores extending across the apex
of the abdomen, in having fewer marginal trilocular pores with none
across the apex of the abdomen, and in having only 4 or 5 multilocular
pores, and from difficile in having at least 8 marginal 8-shaped pores
across the apex of the abdomen, in lacking a sclerotized heart-shaped
plate composing the anal ring, as well as in having the ring setae
practically the same length as the apical setae, and in having only 5 to
8 pores in the atrium of each spiracle.

THE SCALE INSECT GENUS ASTEROLECANIUM 79
Data—Described from unmounted specimens (paratypes) and the
following mounted material removed from U. S. N. H. plants col-
lected by H. Pittier in the Canal Zone: Eleven females and 3 larvae
on Palmae (Cocos sp.?), vicinity of Las Cruces, February 1, 1911,
holotype and paratypes; 2 females on Acristacea ? and 2 females
on Palmae, between Gorgona and Gatun, June 7, 1911, paratypes.
Although this species is closely related to s¢ma/e, it differs from it in
having only 1 or 2 8-shaped pores in the marginal row between the
interruptions and the apical setae, approximately 14 multilocular
pores, the ring setae twice the length of the apical setae, and a
sclerotized heart-shaped area associated with the anal ring setae.
The available larvae are very poor. Consequently the recorded
absence of minute setae near the posterior marginal 8-shaped pores is
not positive, and the exact number of submarginal setae is uncertain.

Data.—Redescribed from one mounted female and one mounted
larva on Styphelia scoparia, Oakleigh, Victoria, Australia, A. Morri-
son, June 5, 1891, U. S. N. H., and unmounted material, four mounted
females, and eight mounted larvae on Leucopogon frazeri, Motueka,
New Zealand, from G. Brittin, December 19, 1987, No. 1384. These
specimens have been identified from the description and figures given
by Maskell (68, pp. 224-226, pl. 16) and Morrison and Morrison (72,
pp. 4-9, pls. 2, 27). Tests at hand agree with those described by
Maskell, including the position on the host with the anterior end of
the test always toward the point of leaf attachment, and the females
studied agree rather well with the characters given by Maskell and by
Morrison and Morrison. Morrison and Morrison prepared their
description from a single specimen labeled as being second stage, but
which they presumed to be an adult. Maskell described the second
stage but it is impossible to be certain whether he had a second-stage
specimen or an adult female, since he did not mention the tubular
ducts. No second-stage specimens being available, it cannot be de-
termined whether the form described by Morrison, and Morrison
actually belonged to the second stage. They did not mention either
the presence or absence of tubular ducts although they did state that
the presence or absence of multilocular disk pores was not determined.
ASTEROLECANIUM EPIDENDRI (Bouché)
(Fig. 22, A—G; pl. 5, K)
In 1844 (10, p. 300) Bouché described Lecantwm epidendri as
follows:
“@ dunkelgelb mit braunem Kopfe, die weisslichen Fliigel am Vorderrande
rothlich. Linge 14 Linie.
“@ rundlich, flach, griinlichgelb, der Rand mit dicht stehenden verliingerten

84 MISC. PUBLICATION 424, U. S. DEPT. OF AGRICULTURE
“Die minnlichen Puppen haben ein braunliches Schild und sind kleiner wie
bei den Weibern. An letzteren ist die Riisselgegend dunkelbraun; das Afterende
ausgerandet. Jung sind sie langlich, hinten verschmalert, flach, gelb mit kurzen
Borsten gefranzt (an denen sich im Alter die Absonderungen ansetzen).
Afterende mit vortretender Fleischspitze und jederseits eine lange Borste; sie
haben alsdann nur eine Linge von 4 Linie.
“Hs ist eine der zierlichsten Scharlachlause.” -
In 1851 (71, p. 112), he again described Lecanium epidendri as
follows:
“QO oval, stark gewo6lbt, runzlig, filzig, dunkelbraun. Linge 4 Linie. Vater-
land Amerika. Auf den Arten von Epidendron.”
The female described in 1844 was unquestionably a species of
Asterolecanium, but the one described in 1851 was probably a species
of Coccus. Its size differentiates it from the epzdendri described in
1844, and there is no reason to believe that Bouché was in error in
the measurement published in 1851, as has been suggested by Lindinger
(62, p. 167). So far as known, there were no references to Lecanium
epidendri Bouché from 1851 until 1868, when Boisduval published
three notes concerning Chermes epidendri (Bouché) in Insectologie
Agricole, the first on April 2 (4, p. 95), the second on May 2 (6, p.
127), and the third in October (7, p. 287). In each note Boisduval
listed the host as L'pidendrum, and in two of them stated that the
insects were found in greenhouses. In Insectologie Agricole, Novem-
ber 1868 (8, p. 301), however, Boisduval described Coccus aureus from
Maranta vittata from hothouses in Paris, and stated that the insect
had been brought to them by a foreigner with exotic plants. In 1869
Targioni-Tozzetti established the genus Asterolecanium and selected
aureum as its type (96, p. 734).
In 1870 Signoret redescribed awreum and indicated that he had
discussed and illustrated this species, though without naming it, in
a characterization of the genus Asterolecanium published in 1869 (87,
p. 101, pl. 4, figs. 5,6). We made the following statement at the end of
the description (88, pp. 277-278) : “Nous devons cette espéce intéres-
sante a l’obligeance de notre collégue et ami M. le docteur Boisduval,
sans lequel nous n’aurions pu faire qu’un travail peu important sur
cette famille.” Study of type material of awrewm which has been avail-
able to the writer has settled the identity of the specimens described
by Boisduval and Signoret under that name, and has proved the
correctness of Targioni-Tozzetti’s identification of specimens from
Anthurium in 1892 (98, pp. 304-311), which Cockerell questioned in
1896 (19, p. 8).
Asterolecanium aureum is doubtless a synonym of epidendri, but the
synonymy must be assumed because Bouché’s specimens of epidendri
presumably do not exist today and it is impossible to place the species
from his description. Bouché described epidendri from orchids in
greenhouses, and Boisduval so reported it, although he later described
aureum from Maranta vittata, a host belonging to the Marantaceae
but rather closely related to the Orchidaceae. Since his specimens
from Maranta are the same species found on orchids in greenhouses
in Europe and on orchids in the West Indies, tropical America, and.
Ceylon, and since no other valid species of Asterolecanium from or-
chids has been encountered in greenhouses in Europe, the writer as-
sumes that aureum is a synonym of epidendri, as indicated by Lindinger
in 1934 (62, pp. 162, 169), and in 1937 (65, p. 180).
THE SCALE INSECT GENUS ASTEROLECANIUM 8)
Study of the type material of oncidii and greeni shows that they
also are synonyms of epidendri. In April 1893 (16, p. 255) Cockerell
listed oncidzi as Planchonia oncidii, n. sp., and in another publication,
also published in April 1893 (17, p. 78), he described the species and
suggested that Lecanium epidendri Bouché might be the same. In
discussing oncidzi in 1896 (19, p. 8) he wrote: “It is probable that the
‘Lecanium’ epidendri of Bouché is identified with this, but Bouché’s
description is very short. If the identity be assumed, epidendri has
long priority.” Thus, in 1893 and 1896 he indicated the possibility
of the synonymy which Fernald listed in 1903 (32, p. 50). Lindinger
was in error in accepting oncidii as a valid species in 1936 (64, pp. 153-
154). A. greeni, described by Marchal in 1904 (67, pp. 455-457),
was placed as a synonym of awrewm by Green in 1909 (42, p. 320).

slightly to distinctly upturned; 2—2.5 mm. in diameter; strongly convex dorsally,
flat ventrally ; clear yellow, transparent, fairly thin; marginal filaments whitish,

many distinct filaments present; elliptical larval exit in margin.
Adult female.—Shape similar to that of test, about 1.5-2 mm. in diameter,
Margin: 8-shaped pores in a single row terminating around five times the

any, one to three times a pore’s length apart; disk pores on either side, or at
end, of 8-Shaped pores, terminating fairly close to apical setae, aS numerous as
8-shaped pores.

longitudinal rows 2 or 3 pores wide, and extending across median area in 5 or 6
transverse rows; submarginal 8-shaped pores in a single row terminating near
first row anterior to penultimate row of multilocular pores, well removed from

penultimate row.
Apex of abdomen: Notch present; setae, apical 18-20 uw long, interapical 12.6
mw long, dorsal 9-10.8 u long (close to, and outside apical, sometimes missing on
1 side of body), inner ventral 5.4 w long, intermediate ventral 5.4 wu long, outer

row very close to margin and appearing almost as a Second marginal row: the
anterior 4 submedian pores slightly larger than the posterior ones, which are
the same size as marginal pores, submarginal pores very slightly larger than
marginal; disk pores between submarginal and marginal, and a few between
submarginal and submedian 8-shaped pores; a pair of minute setae close to
anterior pair of submedian pores.

margins near center, tarsus 2 on inner and 1 on outer margin; tibia one-half
as long as tarsus; 6 pairs of submarginal 8-shaped pores, none between antennae;
usually 1 pair of submarginal minute setae near the third or fourth pair of

Data.—Redescribed from unmounted material and the following
mounted specimens: Ten females on Huryops tenuissimus, Tarkastad,
Cape Province, South Africa, C. P. Lounsbury, 1898, Brain No. 20, type
and paratypes; 2 females and 24 larvae, South Africa, from Collection
of C. K. Brain, received from E. E. Green in 1934; 5 females and 14
larvae on Luryops sp., Tarkastad, Cape Province, South Africa, from
H. K. Munro, received in 1938.
This species differs from all except brevispinwm in having a poorly
defined row of marginal 8-shaped pores, in having the majority of
the marginal and dorsal 8-shaped pores conspicuously invaginated,
and in lacking a ventral submarginal row of setae. In the larval stage
it is difficult to determine whether the pores described as dorsal sub-
marginal should be considered so or as a second marginal row. It is
the only species where a well defined row of ventral submarginal setae
has not been observed in the larva, and where the setae which are
present are so variable in number.
As indicated by Fuller (38, p. 94) and Brain (72, pp. 113-114), tests
of euryopis, When unrubbed, are striking owing to the dense covering
of waxy filaments. Fuller recommended infesting the Harpuis
Bosch (HLuryops tenuissimus) with this insect in order to check the
spread of that plant (38, pp. 93-95).

Described as Coccus fimbriatus in 1834 (34, p. 209), on Coronilla
glauca. Although the collection locality was not given, it may have
been Marseilles, France, because Fonscolombe stated that it was
given to him by Casimir Rostan, then permanent secretary of the
Academy of Marseilles. Also discussed briefly by Signoret in 1868
(S6, p. 515). Material at hand probably represents as authentic ma-
terial of the species as exists.

anterior to anterior spiracular pore bands and ending slightly nearer to apical
setae than to the posterior spiracular pore bands, the row sometimes interrupted
between the pore bands; pores usually about as numerous as 8-Shaped pores of
nearer row near ends of row, and about twice as numerous as those pores near
Spiracular pore bands; disk pores along dorsal row of 8-Shaped pores, terminating
between apical setae and anal opening, nearly half as numerous as 8-shaped pores
of dorsal row, also occurring ventrad of quinquelocular pores, and terminating

The marginal 8-shaped pores are unusual in shape, being practically
as wide as long, a condition found in no other known species of the
genus except phoenicis. ‘The multilocular marginal and spiracular
pores are also unusual though similar ones are “sometimes found in
other species, and the undifferentiation of an anal opening and tube
from the surrounding derm is in definite contrast to the condition

found in other species having 6 setae on the anal ring. Among the
larvae of species having 6 setae on the anal ring, that of gutta is the
only one known with less than 26 marginal 8-shaped pores. Like the
adult, the larva is unusual in not having an anal opening and tube
definitely differentiated from the surrounding derm.

identification of specimens (those he placed as this species belonging

long, interapical 10-12 uw long, outer ventral 8 » long; anal ring with 6 setae,
each about 44 uw long, and with an inner row of 6 and an outer row of 20 pores.
Data.—Described from the following material: One mounted female
on bamboo, China, intercepted at San Francisco, Calif., A. C. Dennett,
November 25, 1936, paratype; one test preserved in balsam and one
mounted female on bamboo, China, intercepted at New York, S. D.
Whitlock, June 8, 1937, holotype.
The paratype specimen of this species is partially covered with
fungus, and the holotype specimen is somewhat torn and mutilated on
the abdomen, consequently it is impossible to determine the exact
position and number of multilocular pores and a few other details.
This species differs strongly from most other species on bamboo in
size, and is the longest species known, the observed test being 4 mm.
long, or 0.56 mm. longer than any observed tests of bambuszcola. It
resembles masuzi most closely but differs from it in having a large
number of dorsal 8-shaped pores, as well as in many less conspicuous
characters.

il (Fig. 36, A-E; pl. 3, B)
Described in 1896 (40, p. 5) as Planchonia miliaris longa. Re- |
described by Green in 1909 (42, pp. 336-337) as Asterolecanium lineare. )
In 1909 (42, in a note inserted in the volume) Green proposed the name
| lanceolatum in place of lineare, which was preoccupied by lneare
5 Lindinger. Although Green stated in 1909 (42, pp. 336, 339) that the
* variety described in 1896 contained a distinct species and variety, all
iy specimens described as miliaris longa in 1896 apparently belonged to
ral the species later designated as lineare and lanceolatum: Since longum
! is the older name, it is the valid name of the species, and /ineare Green
and lanceolatum are synonyms of it.

‘Although the marginal 8-shaped Pits are reduced in number, those
present are well defined. Green (42, p. 336) expressed uncertainty as
to whether there was a complete marginal series. In stained speci-
mens at hand the marginal row of 28 nes shaped pores is apparent in
larvae inside adults, as well : as in those removed from the leaves. Green
did not mention these pores in the early larvae, although he did note
their presence in the later larvae (42, p. 337).
Asterolecanium longum is closely related to miliaris and caudatum,
ae can be separated from these by its small number of marginal
8-shaped pores.

type and paratypes; unmounted material, 10 mounted females, 2
mounted second-stage specimens, and 5 mounted larvae on Quercus

ASTEROLECANIUM MILIARIS variety ROBUSTUM Green
(Gigs AeA plato ae)
Described in 1908 (47, p. 19) on bamboo from Pusa, India. The
form erroneously treated by Green in 1909 (42, p. 339) under the name
Asterolecanium miliaris longum is identical with miliaris robustum
(see discussion on p. 122).
The marginal quinquelocular pores furnish an adequate basis for
distinguishing miliaris miliaris and miliaris robustum. In the typical
form these pores start between the antenna and anterior spiracular
pore band and end approximately halfway between the posterior
spiracular pore band and the last marginal 8-shaped pore. In
miliaris robustum, however, the quinquelocular pores are either absent
er occur in a group of 2 to 15 (usually less than 6) where each spiracu-
lar pore band meets the body margin. Other characters, including
the shape of the specimens and the distance between the marginal
8-shaped pores mentioned by Green (41, p. 19; 42, p. 339), have not
been found sufficiently constant for differentiating the two varieties.
Data—Redescribed from unmounted material, three mounted fe-
males, and four mounted larvae on Bambusa oliveriana, Peradeniya,
Ceylon, E. E. Green, December 1898; unmounted material and three
mounted females on Bambusa sp., Pusa, India, April 1906, from E. E.

ASTEROLECANIUM MINUS Lindinger
(Fig. 37, H—-O; pl. 7, A)
The name Asterolecanium variolosum minor was applied by Leo-
nardi to specimens on Quercus sp. from Italy in 1909." Leonardi’s |
ti | entire notation concerning the variety was as follows: “Vive su
parecchie specie di Quercus. Gli esemplari furono raccolti in varie
localita dell’Italia meridionale.” In 1911 (85, p. 63) Sasscer listed
the name, stating that it had been published by Leonardi without a _
description. In 1912 (61, p. 360) Lindinger placed A. variolosum
minor Leonardi, 1909, as a synonym of variolosum, thereby validating
the name, and in so doing became the author of the variety. Study of
type material shows that mdnus is neither a variety nor a synonym
of variolosum but is a valid species, and it is therefore accorded that
standing. The species here described as minus Lindinger is unques-
tionably the species discussed by Leonardi in 1920 (57, pp. 250-253)
as variolosum Ratzeburg.
Habit.—Living on bark, in pits.

isnt lateral carinae meeting at anterior end, and with transverse striations extend-
ll ing to punctate area, the space on a lateral carina between any two transverse
striations often having the appearance of a small, blunt tubercle; flat to convex
ventrally ; greenish yellow, fairly clear yellow, or rarely brownish yellow, trans-
parent to translucent, shiny, strongly punctate near margin; marginal filaments
whitish ; circular larval exit in margin.
Adult female.—Slightly longer than wide, or circular, 0.85-1.10 mm. long, 0.75-1
wide, usually around 0.95 mm. in diameter.

This species is so similar to minutum that in the adult stage it is
sometimes difficult to differentiate the two although in the larval stage
they are easily separated. In the adult females of minusculum there
are 8 to 17 (usually at least 12) dorsal 8-shaped pores and in those of
minutum 4 to 8; there are 8 to 14 quinquelocular pores in each spiracu-
lar pore band in minusculum and 6 to 10 in minutum,; furthermore, in
minusculum the apical setae are 52 to 56 » long and the ring setae 24
to 30 » long, while in minutwm the apical setae are 44 to 50 p» long
and the ring setae 20 » long. The larvae of minusculum have 4 dorsal
8-shaped pores which are slightly larger than the marginal, while those
of minutum have at least 7, the largest of which is smaller than the
marginal pore of the same segment; also in ménusculum there is 1
trilocular pore near each spiracle, but in minutum 1 trilocular pore
near the anterior spiracle and 2 near the posterior spiracle.

Closely resembling arabidis and stentae, but differing from those in
having fewer marginal and spiracular quinquelocular pores and also
fewer submarginal 8-shaped pores. It differs further from arabidis
in having fewer multilocular and dark-rimmed 8-shaped pores and
shorter apical setae, and from stenfae in having multilocular pores
anterior to the posterior spiracles. Larvae of nevadense differ from
those of arabidis and stentae in having 1, instead of 2, pores near each
spiracle, and 10 or 12, instead of 14, submarginal 8-shaped pores. The
occurrence of either 10 or 12 submarginal 8-shaped pores is most un-
usual, but there can be no doubt about the variation, all specimens
being in excellent condition for critical study.

ASTEROLECANIUM PALMAE Cockerell
(Fig. 47, H-lM; pl. 6, H)
First referred to by Cockerell in 1892 (74, p. 333) as follows: “(16)
* fa Fiorinia camelliae Comst. on Coconut, near Montego Bay. (Coll.
“bs by Dr. Sinclair). On the same leaves I find a curious yellow creature,
| with a fringe all round, and some pink filaments at each end, so is it
possibly the young form of Fiorinia?” Later in 1892 (15, p. 142)
Cockerell commented on this insect as follows: “The ‘curious yellow
creature’ has nothing to do with 772 vorinad, but is a new species of
Asterolecanium, or a closely allied genus.” in April 1893 (16, p. 255)
he listed the species as Asterolecanium palmae, n. sp., and described
it in papers, published in April 1893 (17, p. 77), in 1894 (18, p. 308),
| AINGL aa ISIS (Ge p. 9). The species was erroneously recorded by
| Fernald in 1903 (32, p. 52) as having been described in the Journal of
the Institute of Jamaica, volume 1, 1892 2, page 76.
The original description of Asterolecanium lineare Lindinger was
contained in an article published by Brick in 1909 (13, pp. 449-450),
i] and the species was listed as Asterolecanium lineare, n. sp., in an
+ article by Lindinger immediately following the one by Brick (60, p.
he, 464). The description is inadequate to separate the species from
ie many others found on palm. In 1936, however, Lindinger stated that
| lineare was a synonym of palmae (64, D. 153). Although there is a
possibility that he erred in the assignment, the synonymy is accepted
by the writer, who has not had authentic specimens of lineare for
comparison.

This species is closely related to pasaniae and variabile. It is dis-
tinguished from the former, however, in lacking the sclerotized
tongue-shaped projections of the marginal 8-shaped pores and in hav-
ing setae on the margin of the anal opening. In perplexum the mar-
ginal 8-shaped pores are distinctly larger than in variabile, the
marginal quinquelocular pores terminate nearer the apical setae, and
the latter are 64 » long instead of 48 to 52 » long as in variabile.
Larvae of perplezum have only one pore near the posterior spiracle
while those of variabile have two.

(10 females, 5 second- stage specimens, 11 larvae, 3 adult males, 1 male
nymph, and 1 third- stage male, mounted) on Bambusa sp., Taihoku,
Taiwan (Formosa). R. “Takahashi, April 20, 1929 (part of original
collection from which the species was described).
Closely resembling solenophoroides, but differing from it conspicu-
ously in shape, and in having a well defined marginal row of quin-
quelocular pores; also related ‘to penicillatum.
Although Takahashi stated that there were no dorsal 8-shaped
pores in this species, one or two have been noted in several of the
specimens examined.
ASTEROLECANIUM PSEUDOMILIARIS Green
(Fig. 54, H-S; pl. 7, R)
Described in 1922 (46, pp. 1036-1037) from specimens on Bambusa
sp. collected at Peradeniya, Ceylon.
The dorsal 8-shaped pores of this species vary much more than was
indicated in the original description, and on this account it is nec-
essary to Synonyms , charmoyi with pseudomiliaris. Green described
charmoyi in 1924 (48, pp. 45-46) on Bambusa sp. from Mauritius.
The dorsal 8-shaped pores, said by Green to be less numerous and
smaller in charmoy?i than in pseudomiliaris, vary greatly in number
and slightly in size, and do not furnish a basis for separating the two
forms. Moreover, the marginal 8-shaped pores, which were stated to
be closer together ‘in charmoy? than in pseudomiliaris, are practically -
the same distance apart in all specimens.
With the synonymizing of charmoyi, pseudomiliaris bambusifoliae
also becomes a synonym of pseudomiliaris. Takahashi described this
variety in 1930 (93, p. 11) on Bambusa sp. from Nisui, Taiwan (For-
mosa), and in 1933 (94, p. 35) indicated that it was a synonym of
charmoyi. Specimens bearing the collection data of the type speci-
mens of this variety, and studied by the writer, are the same “as ~
specimens described as charmoy? and pseudomiliaris.

in having some dorsal 8-shaped pores much larger than the marginal
ones, in having only 1 pair of claws, in having 13 to 19 spiracular quin-
quelocular pores instead of 23 to 37, and in having 2 linear sclerotized

Four females, five larvae. one adult male, one male nymph, and one
third-stage male from Bambusa sp., Kachek, A. S. Hitchcock, October
13, 1921, U. S. N. H.. holotype and paratypes; one female from Schizo-
stachyum sp., Hau Laan, F. A. McClure, 1929, paratype; one female

ASTEROLECANIUM PUSTULANS (Cockerell)
(Fig. 56, A-E; pl. 4, F)
Described by Cockerell in 1892 (15, pp. 142-143) as Asterodiaspis
pustulans and redescribed by him in 1893 (17, pp. 77-78) as Planchonia
pustulans,
Asterolecanium pustulans sambuci, described by Cockerell in 1903
(26, p. 112), from material on Sambucus sp. from Cairo, Egypt, is
here synonymized with pustulans. No varietal differences have been
found between the two, the characters considered by Cockerell (26, p.
112) and Hall (50, pp. 4-4) fitting typical pustulans as well as speci-
mens named pustulans sambuci. A. pustulans seychellarum also is here
placed as a synonym of pustulans. Green described this variety on
Hevea brasiliensis from the Seychelle Islands in 1910 (43, pp. 3-5)
and stated, “The variety under consideration differs from the type
merely in superficial characters of the secretionary covering.” In the
writer’s opinion neither the tests nor the morphological structures of
type specimens of pustulans seychellarum exhibit differences, as com-
pared with typical specimens of pustulans, that justify varietal
distinction.

exit in margin.

to each 8-shaped pore near posterior end of row and often nearly to posterior
Spiracular pore bands, elsewhere usually 1 quinquelocular to each 8-shaped pore

hosts from Florida, Cuba, Puerto Rico, St. Thomas, Mexico, Canal
Zone, Honduras, Trinidad, Egypt, Palestine, Madagascar, and Hawaii.
Asterolecanium pustulans is an interesting species in several respects,
but particularly in its tendency to produce pits. This habit, however,
apparently is governed primarily by the susceptibility of the host to
pit formation because some infested hosts do not show any depres-
sions, while others show gradations from shallow pits to deep cavities.
When deep pits are formed there is a tendency for the host tissue to
draw together at the opening, thus concealing the insect. In the
mounted insects all structures are amazingly constant except the num-
ber of dorsal 8-shaped pores. The larva of pustulans is the only one
known to the writer in which there are different numbers of long setae
on the coxae, there being four on the anterior and middle ones but only
three on the posterior coxa.

Data.—Described from specimens (eight females, one second-stage

third-stage males, mounted) from “Tusca” [presumably Acacia monili-
formis|, Cordoba, Argentina, M. Kisliuk, June 20, 1927, holotype and
paratypes. >
This species is particularly interesting in three respects, namely, the
unusually large size of the submarginal 8-shaped pores as compared
with the marginal 8-shaped pores in the adult females, the constancy
with which one seta is missing on one half of the apex of the abdomen
in all stages, and the presence of four submarginal setae on the penulti-
mate segment of the body in the larval stage.
It is rather similar to viridulum.
ASTEROLECANIUM QUERCICOLA (Bouche)
(Fig. 58, F-K; pl. 8, @)
Lecanium quercicola was described by Bouché in 1851 (11, p. 112)
as follows, “ 2 fast kreisrund, erhaben, runzlich, dunkelbraun. Lange
¥Y% Linie. Auf Eichen selten.” In 1870 (88, pp. 279-280) Signoret
redescribed it and transferred it to Asterolecanium. He gave a French
translation of Bouché’s description, which he followed with this state-
ment: “Telle est la description donnée par Bouché d’un type que Von
trouve sur les chénes et que nous possédons a deux états, dont l'un se
rapporte entiérement comme couleur & la description ci-dessus, et
Vautre, d’un jaune pale brillant et transparent, présente & une des
extrémités une macule d’un brun foncé, qui n’est que la dépouille
repoussée vers ce point.” However, while Signoret considered
Bouché’s quercicola to be & species of Asterolecanium, Sanders, in 1909
(84, p. 431), believed it to be identical with Aspidiotus zonatus
Frauenf., and in 1912 Lindinger (67, p. 371) assigned it doubtfully to
Kermes quercus but in 1984 (62, p. 169) listed it as an unknown species.
The original description certainly is inadequate to differentiate this
form from many other scale insects, and the identity of the species
cannot be determined because the type specimens presumably are no
longer inexistence. Boucheé’s guercicola may belong to Asterolecanium,
the specimens treated being either immature or ones in which the
adults had not shrivelled in the test, which would account for the
dark-brown color. Since there is this possibility, and since Signoret
as well as some other writers have adopted this interpretation, it
seems best to assume that quercicola is the species treated below.

A. quercicola, as redescribed by Signoret on oak from Paris, and here
accepted as the true guercicola (Bouché), is distinct from variolosum,
with which it was synonymized by Cockerell in 1899 (21, p. 269), by
Sanders in 1909 (84, p. 431), and by Lindinger in 1912 (67, p. 360).
Habit.—Living on bark, in shallow or deep pits.
Test of female——Nearly circular, 1.25-1.7 mm. long and 1-1.5 wide, usually
1.5 mm. long and 1.4 wide; slightly to distinctly convex dorsally, with posterior
tip flattened, usually with faint transverse striations; slightly or distinctly
convex ventrally; usually greenish, sometimes brownish yellow, transparent,
often shiny, sometimes slightly punctate in lateral areas; marginal filaments

Closely related to minus and variolosum. In the adult stage it can
be distinguished from ménus by the presence of approximately 23 to 33
multilocular pores instead of about 8, and from variolosum by having
23 to 33 such pores instead of approximately 50 to 62. In the larval
stage it can be separated from minus by the presence of about 21 dorsal
8-shaped pores instead of around 30 and by having apical setae 66
instead of 54 » long, and from variolosum by the number of dorsal
8-shaped pores, variolosum having none or rarely 1 to 4.

Data.—Redescribed from specimens (six females, two larvae, one
male nymph, and three third-stage males, mounted) on bamboo, Yati-
yantota, Ceylon, from E. E. Green, letter of March 12, 1910, type.
Attention is here called to three errors contained in the original
description of this species (42, p. 316). There are three pairs of claws
rather than two, as stated, six setae on the anal ring instead of none,
and in the third-stage male, erroneously called second stage by Green,
there are three pairs of setae on the apex of the abdomen, rather than
180 MISC. PUBLICATION 424, U. S. DEPT. OF AGRICULTURE
one. In the third-stage male the anal ring has pores even though
these are absent in the larvae and adult females.
Asterolecanium rubrocomatum is rather closely related to eazqguum
and udagamae, but can be separated from these by the presence of
claws.

apex of the abdomen is heavily sclerotized. It is also unusual in having
large 8-shaped pores ventrally and in lacking ventral submarginal
8- shaped pores.

Adult female. —Nearly circular, ventral surface so much larger than dora
surface, because of its greater convexity, that the whole extent of the slide-
mounted insect is larger than dorsal surface; 0.5-0.65 mm. in diameter.
Margin: 8-shaped pores in a single row which is probably normally complete
and which terminates the length of an apical seta from setal bases and the pores

ary 4, 1922, U. S. N. H., holotype and paratypes.
The chief differentiating character between this species and
castanede, the most closely related form, is the absence of marginal
quinquelocular pores in semisepultum and their presence in castaneae.

locular pores in a single, uncrowded row, in having fewer than 20
quinquelocular pores in 1 each spiracular row, and in having only 3 rows

Asterolecanium stentae is very closely related to arabidis. However,
the multilocular pores of stentae usually are much less numerous, are
arranged differently, and have fewer loculi than those of arabidis.
Another difference between the two is the greater number of dark-
rimmed 8-shaped pores and their conspicuous arrangement in several
transverse rows in arabidis. The arrangement of the submarginal
8-shaped pores is also different in the two. In arabidis they occur in
groups within the row, and occupy a comparatively narrow space,
whereas in stentae they are spaced uniformly and spread out toward
the center of the body. At the apex of the abdomen all the setae
usually are conspicuously longer in arabidis than in stentae, and the
outer ventral setae are nearly anterior to the apical in the former but
are virtually anterior to the interapical in the latter. Larvae of these
species are nearly identical, but the dorsal 8-shaped pores in stentae
are slightly larger in comparison to the marginal pores than in arabidis.
The species also is allied to algeriense, launeae, and nevadense.

about 2.10 mm. long, 0.4 wide; slightly convex dorsally, with a faint median
longitudinal carina: nearly fiat ventrally; pale greenish yellow, transparent, very
thin, punctate; marginal filaments pale greenish yellow, longest at anterior end ;.

Margin: 8-shaped pores in a single row apparently terminating around four
times a pore’s length (arcund two-thirds length of apical seta) from bases of

of antenna; beak without setae; spiracle with bar rather broad, atrium slightly
enlarged and containing 6-9 quinquelocular pores, apparently 4 or 5 similar pores
extending from spiracle to body margin in a single row; multilocular pores, with
9 or 10 loculi, apparently in 3 rows, 6 pores in posterior row, 6 in median, 4 in
anterior ; 2 dark-rimmed 8-shaped pores each side of beak, and a few on abdomen
apparently arranged in 2 transverse rows; Ssubmarginal 8-shaped pores not ob-
served owing to poor condition of specimen; only 1 pair of submarginal setae
observed (others probably present but indéeterminable), this pair near the
posterior pair of marginal 8-shaped pores; 1 pair of setae each in the posterior

and two 9 uw long, tending toward division on dorsal side; ventral surface of apex
faintly sclerotized in dentate rows close to median line.

half of body, posterior pore apparently the smallest, anterior pore the largest,
all one-fourth to one-third smaller than marginal pores; disk pores not observed.

Data.—Redescribed from two tests, one badly wrinkled mounted
female, and two poor mounted larvae from Arundinaria sp., Avisa-
wella, Ceylon, E. E. Green, October 1909.
_The available specimens are very poor. Consequently it was impos-
sible to observe the dorsal tubes, the ventral submarginal 8-shaped
pores, and the submarginal setae in the adult. Inthe female examined
marginal quinquelocular pores were also indeterminable, though they
were mentioned and figured by Green. The anal extremity in this
specimen, is not retracted within the margin as originally described.

Asterolecanium urichi is closely related to difficile and_ simile.
Characters differentiating it from simile are discussed under that
species. It can be separated from difficile by the lack of a conspicuous
interruption in the marginal row of 8-shaped pores, by the absence
of marginal trilocular pores on the anterior end of the body, by the
absence of multilocular pores, and by the length of the apical setae,
which are about twice the length of the ring setae.

i ASTEROLECANIUM VARIOLOSUM (Ratzeburg)
2 x be (Fig. 78, F—P; pl. 5, J)
= FE Described as Coccus variolosus on oak from Kunersdorf, near Pots-
si, dam, Germany, and reported from Friedrichshain, Germany, in 1870
to. (SO, pp. 187-194).
og The original description is practically useless for separating this
a | species from other pit-forming species occurring on the bark of oak.
i Moreover, type specimens of the species have not been available for
i study, and they may be no longer in existence, since they have not been
del located in Eberswalde or Berlin. The species treated here is so com-
mon in Germany, however, that there is a strong possibility it is the
true variolosum. ;
The synonymy indicated by Lindinger (63, p. 130) is not accepted in
pits this paper. Some of the species which he synonymized with vario-
ret losum definitely do not belong to Asterolecanium, and it 1s impossible
Si to tell whether others do or do not. If any of them do belong in this
genus, there is no certainty that they are the same as wariolosum.
Habit.—Living on bark, in shallow to deep pits.
Test of female.—Usually longer than wide, rarely wider than long or cireular;

mi posterior end than elsewhere; elliptical larval exit in dorsal surface at margin.
Flt Adult female.—Slightly longer than wide. posterior end slightly produced ;
1.7-2.15 mm. long, 1.3-1.7 wide, usually 1.95 mm. long, 1.5 wide.
Margin: 8-shaped pores in a single row terminating once or twice the length
of a posterior pore from bases of apical setae, posterior pores 8 uw long and 5

apart; quinquelocular pores in a single row (sometimes in a double row near
spiracular pore bands) terminating 13-46 (usualiy 25-86) 8-shaped pores from
end of row, usually interrupted opposite 22-35 8-shaped pores at anterior end,

This widely distributed species is well known for its destructiveness.
It is closely related to quercicola.
ASTEROLECANIUM VENTRUOSUM (Maskell)
(Fig. 78, Q, R; fig. 79, A—C)
Described by Maskell in 1895 as Planchonia ventruosa (70, p. 63).
Habit.—“This insect forms for itself depressions or pits in the bark, adapted
to the convexity of its ventral surface; and, when it is lifted out, there remain
slender, white, cottony trails, denoting the spiracular regions.” (70, p. 63.)
Test of female——“Test of adult female green, waxy, flat or sometimes slightly
concave. The green colour is in the test itself, and not due to the insect showing
through it. Form of test broadly elliptical, or with a very slight posterior
tapering. Fringe pink or white.” (70, p. 63.)
Adult female —Cireular, posterior end slightly produced; 0.75 mm. in diameter.
Margin: 8-shaped pores mostly in a double row but about posterior 16 pores in
an irregular single row, terminating about one-half length of an apical seta from
setal bases, posterior pores 11 uw long and 7 wide, others 12-13 uw long and 8 wide,
about a pore’s width apart where single, and from a pore’s width to twice a
pore’s length apart where double, the 2 rows less than a pore’s width apart;
quinquelocular pores in a single row interrupted at anterior end opposite 2
8-shaped pores and terminating 4-7 8-shaped pores from end of row of those pores,
less numerous than corresponding 8-shaped pores near end of row, usually twice as
numerous as 8-shaped pores of nearer row elSewhere; disk pores along dorsal
row of 8-shaped pores, terminating sometimes before and sometimes beyond end
of row of those pores and less humerous than they are; disk pores also occurring
ventrad of quinquelocular pores, this row terminating anterior to bases of apical
setae, the pores as numerous as 8-shaped pores of nearer row.
See surface: Minute 8-shaped and disk pores fairly numerous; tubular ducts
( » long.
Ventral surface: Antenna sharply conical, apex spinelike, with 1 seta appar-
ently shorter than diameter of antenna ; 2-4 quinquelocular pores between antenna
and margin ; beak apparently with 1 pair of setae; spiracle with bar fairly broad,
expanded at inner end, atrium slightly enlarged and containing 3-7 quinquelocular
pores, 14-18 similar pores extending from spiracle to body margin in an irregularly
single row; multilocular pores, totaling 91 and with 7-11 loculi, apparently
arranged in 7 complete rows and 1 interrupted row, the latter anterior to posterior
spiracles, the number in each row not readily determinable but posterior row
apparently with 14, penultimate row with 9, next with 13, next with 11, next
with 19, next with 12, next with 9, and anterior row with 4; a few scattered,
dark-rimmed 8-shaped pores ; submarginal 8-shaped pores in a single row terminat-
ing near penultimate row of multilocular pores, about as numerous as corre-
sponding marginal 8-shaped pores of nearer row; submarginal setae in a complete
row terminating near posterior pair of marginal 8-shaped pores; 2 pairs of setae
in posterior row of multilocular pores and 1 pair in each of the next 2 rows.
Apex of abdomen: Notch present; setae, apical 65 uw long, interapical 7.2 uw long,
inner ventral 7.2 « long, outer ventral 9 » long; anal ring with 6 setae 28 u long
and with an inner row of 6 and an outer row of 14 pores, divided on dorsal and
ventral sides ; ventral surface of apex weakly sclerotized close to notch, slightly
reticulate.

THE SCALE INSECT GENUS ASTEROLECANIUM 221
Data.—Redescribed from one mounted female labeled Australia,
Maskell Collection No. 423, U. S. National Museum Catalogue No.
40362, allotype.
Maskell stated (70, p. 62), “Hab. In Australia, on Acacia sp.
I have specimens from Adelaide, sent by Mr. Koebele, on twigs with
dark-red bark, and in these the fringes of the adult are pink; others,
from Sydney, sent by Mr. Froggatt, are on twigs with lghter and
greyish bark, and the fringes are white; but otherwise the specimens
are identical.” From these data, published with the original de-
scription, it seems that the specimen at hand is from the lot collected
by Mr. Koebele. Morrison and Morrison pointed out (73, p. 8) that
the specimens mentioned by Maskell as being from twigs with dark-
red bark and having the marginal fringe pink might be considered
as ventruosum because they are treated first in the description, and
that the specimens from lighter and grayish bark with the marginal
fringe whitish actually represented another species, which they de-
scribed as acaciae (73, pp. 3-4).
The two pores on the antenna mentioned by Morrison and Morrison
probably were setal bases, pores not having been found on the antennae
of members of this genus. The apical setae are 65 » long, instead of
165 » long, as stated by Morrison and Morrison, the latter length un-
doubtedly being a typographical error.
ASTEROLECANIUM VICTORIAE, New species

interrupted rows, the posterior row with 4 or 5 pores, each of next 4 rows with
11-15, each of the next 3 rows with 5-8; 1-3 dark-rimmed 8-shaped pores each
side of beak and a few arranged in 4 or 5 transverse rows posterior to beak:
Submarginal 8-shaped pores in a single row terminating near the second from the
last row of multilocular pores, as numerous as corresponding marginal 8-shaped
pores ; submarginal setae in a complete row terminating near penultimate pair of
marginal 8-shaped pores; 2 pairs of setae in posterior row of multilocular pores,
1 pair in each of next 2 rows.
Apex of abdomen: Notch present ; lobes indicated ; setae, apical 72 « long, inter-
apical 9 u long, one 5.4 u long usually entad of interapical on 1 side of body only,
Inner ventral 7.2 w long, outer ventral 9 « long; anal opening ventral, cireular,
itS margin membranous; anal tube slightly sclerotized, evlindrical: anal ring
With 4 setae 2 uw long.
Larva.—Eliiptical.
