cavities and spots on propleurae black.
Medium spots on vertex much larger. Basal angles of scutel and two dots in front of the transverse line, black. Elytra without fus- cous areas.
Male: Plates long, about two and a half
times aslong as total breadth at base, sides concaveon basal two thirds, thence from the obtuse angle thus formed strongly narrowed to the tips.
Differs in color from the female
.as follows: Head and sculel other than
markings bright yellow. Spots at ocelli
larger and including ocelli. Vertex with a large median black spot at base. Pronotum with two points at apex and a median line, blackish. Veins of elytra somewhat darker towards base.
State of Vera Cruz, Mexico (Rev.

This species belongs
to the novella, group but is very distinct from either novella or anomala.
THREE NEW COCCIDAE OF THE SUBFA-MILY DIASPINAE. BY T. D. A. COCKERELL, MESILLA, NEW MEXICO. As$idiotus (Dias~idiciizts) conz$Ceravuw, n. sp. - 9 scale I 1-3 mm. diam., circular or nearly so, rather convex (about as in rafax), white, with the red-brown exuviae to one side of the middle. First skin usually ex- posed. A white ventral film.
? yellowish-brown, of ordinary form; no
circumgenital grouped glands ; media" lobes close together, large, broad and low, rather like those of spurcatus; second lobe low and broad, subobsolete hut marked by the wide depression between it and the first lobe, it resembles the same lobe in betdae, but is longer; third lobe a rounded prominence, hardly a lobe, as in betdae; three spine-like plates (gland-hairs) in the first interlobular interval; three, larger, behind the second lobe; these branch more or less, the last especially having two long lateral branches; a long and strong spine jwt beyond the third lobe, and another similar spine on the mar- gin a good distance beyond. The two pairs of interlobular incisions are very well-formed and are like those of befulae. Anal orifice large, and only a short distance from the hind end. Lateral portions of caudal plate with numerous filiform (spermatozoon-like) glands.
The embryonic larvae, in the body of the 9, are remarkably large, and have the legs and antennae well formed.
Hat, - Organ Mts., New Mexico. De-
tected by Mr. H. Casad on a small pine tree (doubtless Pims $ot&rosa v. scopHlo~um)
which was brought to Mesilla and used as a Christmas tree. The scales occur plentifully on the upper pan of the trunk. A. conifer- arnm is more like certain European species. than any found in America; it probably
occurs far to the north, and belongs to the boreal or subboreal fauna, reaching its most southern limit, like some other species, in New Mexico.
It is infested by a fungus.
Pseudo'ftarlatoria rioacki, n. sp. - 9 scale I 2-3 mm. diam.,flat, or very slightly convex, circular or nearly so; stained with light cof- fee-brown, except the margins, which remain white, sometimes the whole scale being whit- ish ; exuviae central to sublateral, rather large, exposed, first skin near margin of second, both skins orange-brown, varying to very pale greenish yellow, the first skin sometimes
greenish with a yellow spot at
each end. A white ventral film. 8 scale
smallcr, broad-oval, flat, semitransparent white ; larval skin large, slightly greenish,

tipped with yellow, some distance within the margin of the scale.
9. Brown, of the general type of the
genus. Five groupsof circumgenital glands; caudolaterals of 16 to 18, cephalolaterals about 20, median, seven. Plates and lobes much as in P. $arZatorioides; the two pro- jcclions between the median lobes are longer than the lobes, and subparallel; the median lobes are rounded at the ends, and their sloping sides if produced to a point would form about a right angle, the subbasal
notches of ifurZatorioldes are wanting; the other lobes etc., correspond closely with those of $a-rla-toriotdes. The sides of the segments before the hindmost portion are curiously produced, the outlines of the pro- duced portions rather resembling that of a human nose.
Hab. - On leaves of a forest tree, Campi- nas, Brazil, Jan., 1898. Collected by Dr. Fritz Noack, phytopalhologist of the Insti- tuto Agronomico do Estado de S. Paulo. It is a distinct species, easily recognized by the scale. The exuviae a.re sometimcs quite green, and
the scale may be snow white
except in the centre. The scales mostly
occur along the midrib on the under side of the leaf.
Mytilaspis $erlonga^ n. sp. - $ scale
long and narrow, 3 1-2 mm. long, hardly I mm. wide, convex, straight, very pale
ochreous, exuviae shining apricot color, with a rather coppery tint, first skin ex- posed, second covered. s}' scale similar but much smaller.
2. Orange brown; median lobes fairly
large but not much produced, their outline .about that of a half-circle, the interval be- tween them about us wide as the diameter of 'one; second lobes very broad and low; third ,a little more elevated than the second, and .divided Into two or three lobulcs; fourth replaced by some irregular serration of the margin. The true spincs are rather small, and quite ordinary; hut the spine-like gland- hairs are extrcniely large, quite stout, ex- tending far beyond the lobes, and more or less beset with spinnles at the end. There is one of these gland-hairs at the inner base of each median lobe, one (only one) in the first interlobular interval, one also in the second, and one in the third interlobular in- tervals, and one some distance beyond upon the margin. Anal orifice level with the
hinder portion of the cauclolateral group of glands. Five groups of circumgenital
glands, median of 7, caphalolaterals 14, can- dolaterals 14- or less. Rows of numerous transversely elongate dorsal glands. An- tennae represented by rounded tubercles, emitting numerous bristles. The females
contain embryos with well-formed legs and antennae.
Hab. - Campinas, Brazil, very numerous
on the biu'k of small twigs of Baccharis, Jan., 1898. (Dr. F. Noack.) Nearly all of the
specimens are infested by a chalcidid para- site. M. perlonffa is a distinct species, ea-si. est distingushed by the very large gland- hairs, of which there is but one in the first interlobular interval. There area few Lecan- turn barcharidis on the same twigs.
PROCEEDINGS OF THE CLUB.
11 March, 1898. The 200th meeting of the club was held at 156 Brattle St., Mr. J. W. Folsom in the chair.
Mr. A. P. Morse of Wellesley, Mass., was elected president for 1898,
Mr. W. F. Fiske of Durham, N. H., was
elected a member.
Mr. A. Or. Mayer said that during a stay in the Figi Islands from November 6 to Janu- ary 13, he devoted some time to collecting insects. Among Lepidoptera one finds sev- eral species of Euploeans that seem to be identical with Austi-alia-11 forms. There is one Papilio that is evidently a Qieensland species, and also a Terias that is extremely common. It is probable that all of these butterflies existed upon the islands before the advent of white men.
