to their true generic relationships. The whole group of new 
species described here have a similar habit and are evidently 
closely related, possibly excluding the first new species, and in 
view of the chaotic condition of the genera of the Coccinz it has 
seemed advisable to place them in a well-known genus, from 
which they can be readily transferred to their proper position if 
this should prove necessary. 
Coccus discrepans (Green). 
This record is based on some specimens from the undersides 
of leaves of Murraya calorylon, Botanic Gardens, Singapore, 
August, 1917 (Baker 8940), the individuals attended and 
covered by ants. These specimens have been compared with 
mounts made from material forwarded to the United States 
National collection of Coccide from Ceylon by Mr. E. E. Green, 
the describer of the species. Green lists this species as belonging 
to the genus Saissetia as recognized by the Fernald Catalogue of 
Coccidae; but from an examination of the material at hand, I can 
see no reason for not including it in Coccus as this genus is at 
present recognized by American coccidologists. The only struc- 
tural differences noted in the Singapore specimen, as compared 
with the description and the Ceylon specimens, are that the anal 
plates are wider in proportion to their length in the former than 
in the latter and that no submarginal tubercle has been located 
between the groups of spiracular spines on the Singapore speci- 
mens, although they are present elsewhere. Both of these ap- 
parent differences are in all probablity due to the condition of 
the mounts obtained from the specimens from Singapore, since — 
all these have been rather poor and have apparently been so badly 
crushed in mounting that the anal plates have been flattened. 
For the present another lot of specimens, from the leaves of an 
unknown host, Singapore, August, 1917 (Baker 8934), colonized 
by ants under carton nests, is also considered as of this species, 
although these specimens show some structural differences as 
compared with the other specimens of the species that have been 
examined. There are six well-developed submarginal tubercles 
on each side, two anterior to the first spiracle, one between the 
spiracles, and three posterior to the second spiracle, all widely 
separated. The body of the female, which is fully developed, as 
evidenced by the presence of young larve beneath it, averages 
about one-fourth smaller than the Ceylon specimens ; and, while 
the marginal setz are frayed apically and curved as in the ty pical 
specimens from Ceylon, the two lateral spiracular spines are
