XXIX. On the identity of Coccus floccosus, DeGeer, and 
Orthezia Normani, Doug. By J. W. Dovauas. 
[Read September 7th, 1881.] 
Fottowine Dr. Signoret I had deemed that Coccus 
jloccosus, DeGeer, was synonymous with Orthezia urtice, 
Linn., with the reservation, however, that DeGeer’s 
figure (Mém. vii., pl. 44, fig. 26) was ‘‘rude and un- 
' satisfactory’ (int. Mo. Mag. xvii., p. 175). But at that 
time I did not know the species I afterwards described 
and figured, under the name of Orthezia Normani, in the 
present volume of the Transactions of this Society, 
p. 300, Pl. XYV., figs. 12—15, and a renewed investigation 
induces me now to believe that it was probably this 
species and not O. urtice that DeGeer had before him. 
In his figure the very peculiar character of the dorsal 
lamine in O. Normani—a deep and wide median excision 
—is tolerably represented, but in this latter species three 
or four of the anterior segments only have this con- 
formation, the remainder being mostly narrow and 
straight, whereas in DeGeer’s figure each segment has 
the broad form of lamination equally developed. The 
lateral lamine in DeGeer’s figure are represented of equal 
length and breadth throughout ; whereas in O. Normani 
only the first three or four are broad, curved, and pro- 
jecting, the remainder being narrow, straight, parallel, 
and more backwardly directed. In his description, 
DeGeer says that the lamine are arranged like tiles, or 
the scales of fishes, but this simile is true with respect 
to O. Normani, both as to the dorsal and lateral lamine, 
only when the insect is viewed from the front, because it 
is the upper edge of a lamina that rests upon the lower 
side of the one preceding it; and, with respect to O. 
urtice, the simile is correct only with regard to the 
lamin composing the dorsal ridges, the overlapping of 
the lateral lamine not being evident. His further 
description, ‘‘ Il y en a d’abord une couche au milieu du 
corps, plus courtes que les autres et arrangées sur deux 
lignes, de fagon que celles de l’une de ces lignes vont
