SiGNOiiJiT, Ann. Soc. Ent. Er. (5) ii. pp. 33-40, pi. 7 (pt. ix. and pi. 9 of 
the treatise as a whole) continues his ‘ Essai sur les Cochinelles,’ discussing 
the genera Vinsonia and Ceroplastes. One of the Lecaniides, found on a leaf 
of Mangifera indica with V. ptdchella, Sign., is queried as possibly the cf of 
that species. Ceroplastes radiatus, testudineus, and hydatis, Costa, united 
rightly by Targioni as forms of one species, under the name testudiniformisy 
must retain the name of rusci, L., and Lecaniiim arternisice, Rossi, is possibly 
identical with it. Various stages of this insect are figured. A species of 
Ceroplastes from the Mauritius, living on Eriobotryajaponica 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. 
myriccB, L. Details of C. ceriferuSj Anders, (fig. 3), and psidii, Chav. (fig. 6), 
are given, the latter being queried as a var. of janeirensis (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 [jhid. Bull. p. xxxv et seq.), referring to 
species observed by him in S. France and Italy, incidentally mentions two 
supposed new species under the names Antonia purpurea and Phirmairiu 
hipartita, and oiliers to which no names are assigned. lie also briefly rede- 
scribes Lecanopsis rhyzopkylla, 'larg., and mentions various species found on 
Genista, Mesemhrianthemum, &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 extremel}'^ 
difficult.]
