Neotropical. 
A. (Selenaspidus) articulatus Morg.— 9 scale very flat, grayish-white, appearing orange 
or rufous in the middle, mainly from the insect showing through. The scale 
looks like that of J. aurantii, but if it is lifted up, the flat orange 9, with a 
deep constriction between the cephalothorax and the abdomen, is easily seen 
with a hand lens sufficiently for identification. It occurs on the leaves of 
palms and on a variety of other plants. West Indies, Demerara, Mexico, and 
lately reported by Xewstead from Lagos, W. Africa. (Ent. Mo. Mag., xxv, 352.) 
A. (Chrysomphahts) biformis Ckll. — 9 scale about 2 mm. diam., very dark brown, 
circular to broadly oval, depressed, granulose; exuviae nipple-like, dark red- 
brown, placed to one side of center. $ scale elongate. 9 with three pairs of 
lobes. On orchids. Jamaica and Triuidad. Also from Central America ; the 
specimens showing four groups of ventral glands, rather scattered, cephalo- 
laterals 4 or 5, caudolaterals 5. 
var. cattleyae Ckll. — Exuviae black. On Catthya bowringiana. Jamaica. (Gard. 
Chron., May 6, 1893, p. 548.) 
var. odontoglossi Ckll. — Exuviae pale, black when rubbed. On Odontoglossum 
grande. .Jamaica. (Gard. Chron., May 6, 1893, p. 548.) 
A. (ChrysompbaJus) bowreyi Ckll — 9 scales crowded on the plant, elongate, gray, 
with the blackish exuviae toward one end. 9 with three pairs of lobes, none 
very prominent, margin serrate beyond the lobes; four groups of ventral glands, 
cephalolaterals about 7, caudolaterals about 8. On Agave rigida. Jamaica. 
(Ent. News, 1894, p. 59.) 
A. (Hemiberlesia) crawii Ckll. — 9 scale about 2 mm. diam., circular, moderately con- 
vex, dull reddish-gray, rather pale ; exuviaB nearly marginal, concolorous, incon- 
spicuous, except the first skin, which is marked by a little shining yellowish 
prominence. Scales largely covered by the red-brown epidermis. Removed 
from the twig they leave a conspicuous white mark. 9 similar to cydonicv ; 
four groups of ventral glands, caudolaterals -4, cephalolaterals 5. On twigs of 
grapevine from Mexico, found by Mr. Alex. Craw in the course of his quarantine 
work. The passenger who brought the plants said they were sarsaparilla, but 
Mr. Craw thinks it is grapevine, and I am of the same opinion. 
A (Chrysomphalus) dictyospermi Morg. — 9 scale grayish-white, depressed, oval, exu- 
viae central, light yellow, center of larval skin dark orange. 9 with three 
pairs of lobes ; a conspicuous pair of long, serrated plates luterad of third lobe. 
On Dictyo8pervium album. Demerara. (Ent. Mo. Mag., 1889. p. 352.) There are 
four groups of ventral glands, cephalolaterals 3 or 4, caudolaterals 2. It occurs 
as a hothouse species in the United States, 
var. arecae Xewst. — 9 scale more circular, deeper colored, with a nipple-like 
prominence surrounded by a depression, beyond which is a strong circular 
ridge. On Arera triandra. Demerara. (Ent. Mo. Mag., 1*93, p. 185.) 
var. jamaicensis Ckll. — 9 scale more circular, red-brown, no conspicuous central 
depression or ridge. Jamaica. On Cycas and rose. 
A. (Diaspidiotus) diffinis Xewst. — 9 scale convex, slightly elongate, grayish-brown, 
exuvia j covered, brown when rubbed. 9 with three pairs of lobes, plates and 
ventral grouped glands wanting. Demerara. (Ent. Mo. Mag., 1893, p. 186.) 
var. lateralis Ckll. — 9 with distinct plates*. Jamaica, on Jasminum. This is 
very near to pnniciv, but the scale is brownish-white to brown, with the exu- 
viae away from the center, and the groups of ventral glands seem to be absent. 
A. (Chrysompbalus) ficus Ashm. — 9 scale circular, 2 mm. diam., black or blackish, 
with the covered exuvia* reddish or orange. 9 with three pairs of well- 
developed lobes and four groups of ventral glands. On Ficus nitida and Citrus. 
Elorida, Cuba, Mexico, Australia, Ceylon, Egypt. It lives on a great variety 
of plants. Mr. Pettit sent it to me from the Shaw Botanic Garden, St. Louis, 
on Laurus virginiana. It is common in the West Indies. Mr. Hy. Tryon states
