A. (Diaspidiotus) niger Sign. — 9 scale circular, black, exuviae yellow; two lobes; no 
grouped glands. On willow. France, (Essai, 1809, p. 130.) 
A. (Aspidiotus 8. sir.) oleae Colv. — On the olive in Spain, producing yellow spots on 
the fruit at the points attacked. Through the kindness of Dr. Howard I have 
been able to see the "Gaceta Agricola del Ministerio de Fomento," Vol. XIV, 
No. 2 (1880), containing ColveVs description. The insect is said to most 
resemble A. nerii, ceratonice, and villosus, and we are told how these three differ 
from it, without any direct statement of its specific characters. It seems to 
be nearest to nerii, differing only in the J . It is worth while to remark that 
in the same paper there is described a Diaspis olece Colv., which has escaped 
the notice of coccidologists. This may not be a Diaspis, as the 9 scale has a 
black spot in the middle marking the exuviae, and $ scale is dirty gray. The 
9 itself is of an intense mulberry color. 
A. (Subtj. f) oleastri Colv. — Description not seen. Described in "Xuevos Fstndios 
sobre algunos insectos de la familia de los Coccidos." (Valencia, 1882.) 
A. (Diaspidiotus) ostreaeformis Curt. — 9 scale, similar to that of A. ancylus. 9 with 
four lobes, the median pair much the largest. Western Europe. A. pari Licht., 
is the same. See Douglas, Ent. Mo. Mag., XXIII, 239; Morgan, Fnt. Mo. Mag., 
XXV, 350. It occurs on apple, plum, cherry, and Calluna vulgaris. Also on 
peach at Isleworth, England (G. M. Fenn.). I found English specimens of 
this species to be attacked by a fungus similar to that which destroys American 
species of Diaspidiotus. I have seen it from Alameda, Cal. (Div. Ent., 351 k .) 
A. (Diaspidiotus) oxyacanthae Sign. — 9 scale blackish-gray, exuviae yellow; median 
lobes large ; grouped glands present. On Crataegus oxyaeantha. 
A. (Diasjjidiotus) patavinus Berl. — 9 scale oval, fuscous or fuliginous, exuvke not 
central, length of scale nearly 1A mm. 9 much as in A. spurcatus or J. vitis, 
median lobes large and broad, second lobes low, separated by a wide interval 
from first, plates serrate, four or five groups of ventral glands. On bark of 
cherry. Italy. (Riv. Pat. Veget., IV, 350.) 
A. (Targionia) sigaoreti Comst. — 9 scale black, very convex, exuviae central. On 
Cineraria maritima. France. (Sign., Essai, 1870. p. 106; Comst., Cornell Rep., 
1883, p. 82.) Targionia nigra Sign, is the same. 
A. (Diaspidiotus) spurcatus Sign. — 9 scale blackish-brown, exuviae yellow. Grouped 
glands present. On poplar. France. Essai, 1869, p. 138. A variety on l'la- 
tanus orientalis in Italy. (Berl. and Leon., Cherm. Ital., Ease. 1.) 
A. (Diaspidiotus) tiliae Sign. — 9 scale gray; only two lobes; grouped glands present, 
lateral groups of 9 or 10, median group of 7 or 8. This species is probably 
widely distributed in Central Europe; Dr. M. llollruug has a reference to it 
in his Halle Bulletin of 1891. 
A. (Diaspidiotus) villosus Targ. — 9 scale circular, grayish, depressed, exuviae not 
central. 9 with two lobes; groups of ventral glands of about 3 each. On 
leaves of olive. 
A. (Diasjndiotus) vitis Sign. — 9 scale dark gray, exuviae more or less covered; when 
rubbed the exuviae are brilliant black. 9 with only two lobes. On litis, 
near Nice; on raisins from Algiers. 
A. (Diaspidiotus) zonatus Frauenf. — 9 scales gray or even nearly black, exuvia* red- 
dish-yellow. 9 with two pairs of lobes; grouped glands usually absent, but 
once reported as present by Morgan. The 9 scales occur upon the branches, 
the $ scales upon the leaves, of oak. Widely distributed in Europe. A. 
quercus Sign., is the same. See Morgan, Ent. Mo. Mag., XXIV, 207, and 
XXV, 120 ; and Xewstead, Eut. Mo^Mag., N. S. ; IV. 279. 1893. Morgan figures 
the J.
