SiGNORET, Ann. Soc. Ent. Fr. (5) ii. pp. 83-46, pi. 7 (pt. ix. and pi. 9 of 
the treatise as a whole) continues his ' Essai sur les Cochinelles,' discussing 
the genera Vinsonia and Cerojjlastes. One of the Lecaniides, found on a leaf 
oi Mangifera indica with V. pulcheUa, Sign., is queried as possibly the ^ of 
that species. Ceroplastes radiatus, testudineus, and hgdatis, Costa, united 
rightly by Targioni as forms of one species, under the name testtidiniformis, 
must retain the name of 7^usci, L., and Lecanium aHemisice, Rossi, is possibly 
identical with it. Various stages of this insect are figured. A species of 
Ceroplades from the Mauritius, living on Eriohotryajaponica and Psidium, is 
described as new (p. 38) under the name vinsoni (fig. 2), and is also queried 
as being a form of C. psidii, Chav., or janeirensis, Gray, or possibly of C. 
myricce^ L. Details of C. ceriferus, Anders, (fig. 3), and psidii, Chav. (fig. 6), 
are given, the latter being queried as a var. oi janeirmsis (fig. 4). C.fair- 
mairii, Targ. (fig. 7), cassice, Chav., chilensis, Gray (fig. 5), jamaicensis, 
White (? =janeirensis and psidii), and a species from Egypt, occurring on 
Mimosa nilotica, and briefly described (p. 46) under the name mimosce, are 
also noticed. The same author {ibid. Bull. p. xxxv et seq.), refemng to 
species observed by him in S. France and Italy, incidentally mentions two 
supposed new species under the names Antonia purpurea and Fairmairin 
hipartita, and others to which no names are assigned. He also briefly rede- 
scribes Lecanopsis rJiyzophylla, Targ., and mentions various species found on 
Genista, Mesembrianthemum, &c. Coccus vitis, according to his experience, 
does not hibernate at the roots of the plant. [The semicolloquial and un- 
scientific treatment employed renders an analysis of this work extremely 
difficult.]

Both sexes of Aspidiotus visci, I^ciw, = Diaspis (Coccus) visci, Schrank, 
from the mistletoe, Vienna, are fully described (with account of economy) 
and figured, with details of external anatomy, by Low, Verh. z.-b. Wien, 
xxii. pp. 273-278, pi. iv. The subfamily Diaspides is briefly characterized, 
and Aspidiotus, Diaspis, Chionaspis, Fiorinia, Parlatoria, Mytilaspis, Leucodi- 
aspis, Aonidia, and Targionin are referred to it.
