In addition to cotype specimens 
kindly forwarded to the Bureau of 
Entomology by the describer of the 
species and collected at Yokohama, 
Japan, on Ardisia japonica (Myrsina- 
ceae), the writer has examined a single 
specimen from Brooksville, Fla., on 
root of Lawsonia inermis (Lythraceae) 
collected by L. V. Bottimer at quaran¬ 
tine, Washington, D. C., Mar. 27, 
1924 (F. H. B. No. 49655) and several 
specimens from Rockville, Pa., in ants’ 
Fig. 42 .—Nipponorthezia ardisiae: Adult female, 
body, dorsal and ventral; X about 25 
nest, collected by F. M. Trimble, 
February 14, 1921 (No. 0-105). 
The discovery of this curious coccid 
in the United States raises a question 
as to its probable native home, and as 
to whether it is as widely distributed 
naturally as Orthezia cataphracta. In 
a measure this discovery parallels the 
finding of another supposedly Japanese 
species, Matsucoccus matsumurae (Ku- 
wana), apparently widely distributed 
through the Atlantic Coast region of 
this country. Until more is known 
regarding both of these species, this 
widespread and isolated distribution 
can hardly be looked upon as natural, 
and it suggests the possibility that the 
spread has been brought about through 
the movement of ornamental plants or 
nursery stock. 
NIPPONORTHEZIA HISPANICA (SILVESTRI) 
Reference. —Silvestri, 1924, Bol. 
R. Soc. Espanola Hist. Nat. 24: 170- 
172, figs, i-iii (as Orthezinella). 
If an exception be made of the single 
character of the number of antennal 
segments, then this species, as de¬ 
scribed by Doctor Silvestri, appears to 
agree closely with the genotype of 
Nipponorthezia in all generically im¬ 
portant structural characters. Since 
neither the ovisac nor the ovisac band 
of spines is described or figured by 
Doctor Silvestri, it is evident that his 
specimens are preadult. It seems to 
the writer a possibility that the ap¬ 
parent division of the terminal portion 
of the antenna into 2 parts may be 
apparent only and due to some factor 
in the preservation and treatment of 
the specimens before study rather than 
to the actual presence of a joint. 
The species was described from Al- 
geciras, Spain. No specimens have 
been available for examination. 
NIPPONORTHEZIA NEOTROPICALIS (SIL¬ 
VESTRI) 
Reference. —Silvestri, 1924, Bol. 
R. Soc. Espanola Hist. Nat. 24: 172- 
174, figs, iv-vi (as Orthezinella). 
The placing of this species in the 
genus Nipponorthezia is even less 
certain than was that of the preceding 
species, and it has been so placed 
largely because its describer considered 
it to be congeneric with hispanica. 
The species was described from San 
Jose, Costa Rica. No specimens have 
been available for examination.
