scale-like plates; grouped glands present. On Ruscus aculeatus. Italy.

-central; median lobes very large; grouped glands wanting. 4g scale ellip-

the thoracic band almost invisible, ete. On Ceratonia at Nice. 
A. (Aspidiotus 8. str.) erice Boisd.—Resembles nerii, On Erica mediterranea in 
France. (Nomen seminudum.) 
A. (Aspidiotus s. str.) denticulatus Targ.—@ scale thin, transparent; grouped giands 
wanting. On Rubia peregrina. Italy. 
A. (Aspidiotus s. str.) geniste Westw.—On Genista. Similar to 4. nerii. (Nomen 
seminudum. ) 
A. (Aspidiotus s. str.) gnidii Sign.—On Daphne gnidium. Similar to A.nerii. (Nomen 
seminudum. ) 
A. (Aspidiotus s. str.) hedere Vall.— @ scale yellowish-brown, exuvie central and

A. (Diaspidiotus?) ilicis Sign.—@Q scale grayish-yellow, exuvie nearly marginal; 
grouped glands four innumber, On Quercus iler. France. (Essai, 1869, p. 123.) 
A. (Diaspidiotus) juglandis Colv.— 2 scale small, reddish, almost always isolated; i.e., 
not massed. @ with two pairs of lobes, the median ones much the largest; 
four groups of ventral glands, cephalolaterals 8 to 12, caudolaterals 6 to 9; a 
single orifice marking the median group. The rows of dorsal glands, four in 
number, are very well marked; the first of 3 or 4, the second of 7 or 8, the 
third of 22 to 24, and the fourth of 16 to 18. Found in Catalonia, NE. Spain. 
{ think this is the same as 4. juglans-regiw ; both were published in 1881. Ido 
not know which has priority. This is not A. juglandis Fitch, 1856, which is 
Mytilaspis pomorum. 
A. (Aspidiotus s. str.) lentisci Sign.— 9 scale yellowish-brown; allied to nerii. 8. France 
and Algeria. 
A. (Aspidiotus s. str.) minimus Leon.— 9 scale suboval. 9 yellow, very large median
