grouped glands four in number. On Quereusilex. Franco. (Fssai, 18(59, p. 123.) 
A. (Diaspidiotus) juglandis Colv. — 9 scale small, reddish, almost always isolated ; i. e., 
not massed. 9 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. 
I think this is the same as A. juglans-regias / both were published in 1881. I do 
not know which has priority. This is not A. juglandis Fitch, 1856, which is 
MijtUaspis pomorum. 
A. {Aspidiotus s. str.) lentisci Sign. — 9 scale yellowish-brown; allied to nerii. S.France 
and Algeria. 
A. (Aspidiotus s. str.) minimus Leon. — 9 scale suboval. 9 yellow, very large median 
lobes, a smaller second pair, no groups of ventral glands. The small 9 scales, 
less than a mm. diam., are found on the leaves of Quercus ilex. Portici, Italy.
