Targioni-Tozzetti (Atti Soc. Ital. Sci. Nat. xi. pp. 694-738) describes 
the general structure and natural history of the insects of this family, and 
gives a synonymic catalogue of the genera and species admitted by him. lie 
divides them into four tribes, namely : — 
1. Orthezites: Abdomine cauda lloccosa penicillata terminal!, oculi 
granosi. 
2. Coccite $ : Abdomine stylo brevi, setisque 2 terminato. 
3. Lecanites : Foemina hexapoda infixa paraniorphosi gallseformis anten- 
nata, hexapoda, raro apoda, exantenuata. 
4. Diaspites : Foemina metamorphosi inchoata apoda pupaeformis. 
Several new genera and species are indicated, but not described in the 
catalogue. 
Targioni-Tozzetti has published (Mem. Soc. Ital. Sci. Nat. iii. No. 3) a 
most important memoir on the anatomy and physiology of the insects of tliis 
family. It is accompanied by seven plates, for the most part representing 
anatomical structures ; but numerous species are figured in various stages of 
growth. 
Targioni-Tozzetti, in describing a new genus of this family, establishes 
a new tribe for its reception and that of his genus PolUnia, and gives the fol- 
lowing table of the tribes into which he now divides the Coccidce (Full. Soc. 
Ent. Ital. i. p, 260) : — 
I. Metamorphosi nulla 
TI. Metamorphosi paramoi-photica 
III. Metamorphosi I complicata . . . .

6. Diaspites. 
SiGNORET (Ann. Soc. Ent. Fr. 4® s«5r. ix. pp. 97-104) publishes the third 
part of liis “ Essai sur les Oochenilles.” It contains a general indication 
of the genera into which he divides these insects, with very brief characters, 
but illustrated by figures on the accompanying plate (pi. 4). These figures 
are as follows : — Aspidiotus, figs. A, B ; Diasjns, fig. D ; Fiorinia *, fig.s. 
2 & C ; Parlatoria *, fig. 3 ; Mytilaspis, fig. 1 ; Leucodiaspis (Leucaspis 
Targ.), fig. 4 ; Asterolecanium figs. 5 & Q ; Philippia {Filippna *, Targ.); 
fig. 7 ; Fricerus, fig. 8 ; Coccus, fig. 9 \ Callipappus, fig. 10 j Margarodcs, fig. 12 ; 
Porphyrophora, fig. 13. 
Asjndiotus. Signoret (Ann. Soc. Ent. Fr. 4® si5r. ix.) describes and some- 
times figures the following known species of this genus : — A. affinis (Targ.), 
p. 114; A. aloes (Boisd.), p. 114, pi. 5. fig. 1 ; A. hetidce (Barenspr.), p. 115; 
A. caldesii (Targ.), p. 116 ; A. camellice (Boisd.), p. 117, pi. 5. fig. 9; A. cy- 
cadicola (Boisd.), p. 119 ; A. dcnticulatus (Targ.), p. 120 ; A. epideiulri 
(Bouch^), p. l21, pi. 6. fig. 1 ; A.ericce (Boisd.), p. 121 ; A. genistce (Westw.), 
p. 122 ; A. hederce (Vallot), p. 122, pi. 6. figs. C, E, F ; A. kennedyee (Boisd.); 
* The genera thus marked are new genera indicated by Targioni-Tozzetti 
in his catalogue of Coccidae, and here briefly characterized by Signoret, from 
Targioni’s notes to him.
