It is of interest to ask how far south Diaspidiotus goes in the Eastern 
Hemisphere. Mr. Green sends me a species found on Cycas in Ceylon, 
which he calls A. cyanophylli.. But Signoret’s cyanophylli belongs to 
Aspidiotus s, str., or at any rate is very close thereto, while Mr. Green’s 
Ceylon species is a modified type of Diaspidiotus, largely comparable to 
the neotropical Hemiberlesia. I give a figure of the Ceylonese so-called 
cyanophylli (fig. 7) It may be named A. greenii. 
Attention must also be directed to certain types which seem inter- 
mediate, more or less, between Aspidiotus s. str. and Diaspidiotus, 
while at the same time they recall 
By Chrysomphalus. Such are A. trilo- 
{ i bitiformis fvom Ceylon (fig. 8) and 
it. i LA I ees \ an apparently new species from 
( js \\ England,which Mr. Newstead has 
, er SAN i ‘ taken for A. hedere (fig. 9). No 
one could take trilobitiformis for 
a Diaspidiotus, but the so-called 
hedere looks more like one at first 
fhe Spe ‘hen sight. It may besaid that as Aspi- 
diotus s. str. is to Parlatoria, ete., 
so is Diaspidiotus to Mytilaspis 
and Chionaspis. The parallel is 
not exact, but it is approximate, 
HEMIBERLESIA Ckll. 
This name replaces the preoccu- 
pied A spidites Berl. and Leon., but 
with a very different significance. 
The type is A. rapax; and perni- 
Fs eee fer ec eae ciosus, tenebricosus, smilacis, and 
Fic. 9.—Aspidiotus nes ee Newstead). minim uss referred to Aspidites by 
Berlese and Leonardi, all belong 
elsewhere—the first to Diaspidiotus, the next two to Chrysomphalus, 
and the last to Aspidiotus s. str. This subgenus really represents a 
southern modification of Diaspidiotus, with a convex scale and large 
median lobes, the others being suppressed. It appears to be exclu- 
sively American, and belongs to the tropical and lower austral regions, 
except that one species (A. converus) occurs the upper Sonoran, and 
another (A. wim?) in the corresponding zone in I]linois. 
CHRYSOMPHALUS Ashm. 
This subgenus must be credited to Ashmead, as at the time of publi- 
cation Riley expressly disclaimed responsibility, though he had written 
the name first in his MSS. The first definition was given by Berlese 
and Leonardi; the type is A. ficus. In this subgenus the characters 
of the female are somewhat as in Aspidiotus s. str., but the chitinous
