Japanese. 
A. (Diaspidiotus) andromelas Ckll.—Resembles 4. perniciosus; exuvie of male scale 
wholly black, without any light dot and ring. On ‘‘ Phetenia glauca”—I find 
no such name in the Index Kewensis. 
A. (Pseudaonidia) duplex Ckll.— 2 scale subcircular, moderately convex, dark black- 
ish brown; exuviw nearly at the side, orange. 9 with very large median 
lobes, and three other pairs of very small lobes; plates scale-like; four large 
groups of ventral glands, and two orifices representing the median group; 
lattice-work pattern as in 4. thee. Japan. On camellia, orange, camphor, 
azalea, tea, Olea fragrans, ete. On azalea in Washington, D.C. (Div. Ent.) 
A. (Diaspidiotus) perniciosus var. albopunctatus Ckll.— ¢ scale with the pale dot and 
ring very distinct. Japan. On orange. Also found by Mr. Craw on plum 
from Japan. 
A. (Odonaspis) secretus Ckll.—@ scale white, shiny; exuvie exposed, shiny, rather 
large, very pale yellow, placed rather to one side. Q when adult with a sin- 
gle (median) lobe, as is the case also with d. wiilobis; two elongated groups 
of ventral glands, with 80 to 90 orifices in each. On bamboo in Japan; on 
Arundinaria in Ceylon. (Green, Coccide of Ceylon, p. 47, Pl. XV.) 
Nearctic. 
A. (Diaspidiotus) esculi Johns.—@ scale about 2} mm. diam., dirty gray, exuvis coy- 
ered, orange-red whenrubbed. @ yellow, only one pair of lobes, plates simple, 
spines prominent; four groups of ventral glands, cephalolaterals 5 to 17, can- 
dolaterals 4 to 11. On bark of Msculus californica. California. (Bull. Ill. 
Lab. N. H., LV, 387.) 
A. (Diaspidiotus) ancylus Putn.—Q scale nearly circular; exuyie sublateral, reddish 
when the covering film is removed. The 9 has ventral grouped giands, On 
ash, maple, beech, linden, oak, osage orange, peach, hackberry, bladder nut, 
and water locust. Iowa, New York, etc. Putnam, in Trans. Iowa Hort. Soc., 
1877, p. 321, says the scale is usually of a light drab color, which certainly 
does not accord with what we commonly know as ancylus. However, he proba- 
bly examined old scales, which eventually become pallid; and from the rest of 
his writings on the insect there can hardly be any doubt as to what was 
intended. He refers to the eggs. 
A. (Hemiberlesia?) bigelovie Ckll.n.sp. (Fig. 12.)— 9 scale on twigs, like that of a Hemi-_ 
berlesia, size and shape of 4. rapaz, but dull grayish-brown; exuvize placed to 
one side as in rapax, whenrubbed shining black, but more or less covered by a 
film of white secretion. Removed from twig the scales leave a white patch. 
© circular, deep brownish-orange; no groups of ventral glands; no plates; lobcs 
subobsolete. See the figure, which is froma Q full of embryos. Los Angeles, 
Calif., on Bigelovia brachylepis. (Div. Ent., 4973, coll. by D. W. Coquillett.) 
I do not know whether or not to consider this an extremely degenerate type of 
Hemiberlesia; it is certainly very peculiar. 
A. (Diaspidiotus) coloratus Ckll.—@ scale about 1} mm. diam., broad oval, flat, dull 
pale orange-brown; exuvize concolorous, first skin somewhat paler. 2 much 
like wow; ventral glands present. On Chilopsis in the Rio Grande Valley, 
N. Mex. 
A. (Diaspidiotus) comstocki Johns.— ° scale rather flat, cream-buff, the part covering 
the exuvie brownish or concolorous. @ pale yellow; two pairs of well-devel- 
oped Jobes, the tips of the median pair below the level of the tips of the 
second pair, after the manner of 4. destructor; 4 groups of ventral glands, 
cephalolaterals of 6, caudolaterals of 4. On leaves of sugar maple. ITlinois 
and New York. (Bull. Ill. Lab. N. H., IV, 383.) 
A. (Hemiberlesia) convexus Comst.— 9 scale similar to that of rapax, but more opaque. 
Grouped glands present. On poplar and willow,
