A. (Diaspidiotus) niger Sign.— 9 scale circular, black, exuvixe yellow; two lobes; no 
grouped glands. On willow. France. (Essai, 1869, p. 130.) 
A. (Aspidiotus s. str.) ole Colvy.—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 Colvée’s description. The insect is said to most 
resemble 4. nerii, ceratonia, 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 inthe ¢. It is worth while to remark that 
in the same paper there is described a Diaspis olew Coly., 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 exuyiw, and ¢ scale is dirty gray. The 
2 itself is of an intense mulberry color. 
A. (Suby. ?) oleastri Colv.—Description not seen. Described in ‘Nuevos Estudios 
sobre algunos insectos de ia familia de los Coccidos.” (Valencia, 1882.) 
A. (Diaspidiotus) ostreeformis Curt.— @ scale, similar to that of 4. ancylus. 2 with 
four lobes, the median pair much the largest. Western Europe. A. pyri Licht., 
is the same. See Douglas, Ent. Mo. Mag., XXIII, 239; Morgan, Ent. Mo. Mag., 
XXYV, 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.) 
A. (Diaspidiotus) oxyacanthe Sign.— scale blackish-gray, exuviwe yellow; median 
A. 
lobes large; grouped glands present. On Crataegus oxyacantha. 
(Diaspidiotus) patavinus Berl.—@Q scale oval, fuscous or fuliginous, exuviwe not 
central, length of scale nearly 1j mm. 2 much as in 4, spurcatus or A. vilis, 
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.) 
(Largionia) signoreti Comst.— @ scale black, very convex, exuviw central. On 
Cineraria maritima, France, (Sign., Essai, 1870, p. 106; Comst., Cornell Rep., 
1883, p. 82.) Targionia nigra Sign. is the same. 
(Diaspidiotus) spurcatus Sign.— Q scale blackish-brown, exuvie yellow. Grouped 
glands present. On poplar. France. Essai, 1869, p. 138. A variety on Pla- 
tanus orientalis in Italy. (Berl. and Leon., Cherm. Ital., Fasc. 1.) 
(Diaspidiotus) tilie Sign.— Qseale 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. Hollrung has a reference to it 
in his Halle Bulletin of 1894. 
(Diaspidiotus) villosus Targ.— Q scale circular, grayish, depressed, exuvice not 
central. 9 with two lobes; groups of ventral glands of about 3 each. On 
leaves of olive. 
(Diaspidiotus) vitis Sign.—Q scale dark gray, exuvie more or less covered; when 
rubbed the exuvie are brilliant black. 2 with only two lobes. On Vitis, 
near Nice; on raisins from Algiers, 
(Diaspidiotus) zonatus Frauenf.— Q scales gray or even nearly black, exuvie red- 
dish-yellow. @ with two pairs of lobes; grouped glands usually absent, but 
once reported as present by Morgan. The ¢ scales occur upon the branches, 
the ¢ scales upon the leaves, of oak. Widely distributed in Europe. 4, 
quercus Sign., is the same. See Morgan, Ent. Mo. Mag., XXIV, 207, and 
XXV, 120; and Newstead, Ent, Mo,Mag., N.S.,1V.279, 1893, Morgan figures 
the g.
