leave the specimens on Pinus from Japan as an undescribed species 
which will be described presently by Professor Kuwana.® 
8. It has not been possible from a comparative study of the single 
unmounted male specimen and the mounted parts of another male 
in the Maskell collection to determine anything regarding the proper 
status of these male specimens. 
9. The correctness of the tentative conclusions given above can be 
verified only by the examination of additional material, including 
larvae, from the localities and hosts in question. 
Genus MONOPHLEBULBUS Cockerell. 
Re ference-—Morrison and Morrison, Proc. U. 8. Nat. Mus., vol. —9, 
art. 12, 1922, p. 4. . 
This genus has already been described and discussed at such lens, 
as the condition of the specimens of the type species would permit. 
On undertaking a careful study of all the species of the genus J. »no- 
phiebus that had been described by Maskell it became evident that 
M. crawfordi and its variety pilosior were closely related to and con- 
generic with M. fuscus, the genotype of Monophlebulus. An exami- 
nation of the undetermined material of this group in the Coccid col- 
lections available in Washington produced two apparently new species 
of the genus Monophlebulus, and these have been described below. 
With more or less material of all the known species that seem to be 
entitled to inclusion in this genus available, their relationships 
and specific differences are dicussed at some length following the 
descriptions. 
MONOPHLEBULUS CRAWFORDI (Maskell).

The Maskell collection includes the following slide mounts of this 
species: One of ‘“‘adult females, 1888,’’ one of antenna and foot of 
female, 1891, and one of ‘“‘larva, 1892,”’ and besides a few unmounted 
specimens under No. 92, while a few specimens from the local col- 
lections have also been available for study. From the above it will 
be evident that only the 1888 slide and an unmounted male are from 
the type material of this species. 
Adult female—External appearance discussed in some detail by 
Maskell in his various descriptive notes on the species and therefore 
not considered here, nor are the antennae and legs, which appear to 
possess no specific nor even generic peculiarities; body, as mounted, 
elongate oval, slightly broader behind the middle; derm clearing only
