Aside from the very obvious difference in the presence or 
absence of the “submarginal compound pores, ” the two pre- 
ceding species may be separated very easily b} r a comparison 
of a number of other structural characters, as the shape and 
size of the marginal setse, the distribution of the ventral disk 
pores, the character of the dorsal pores in the adult female, and 
the conspicuous difference in the lengths of the submarginal 
setae in the larvae. 
Under the name Pseudophilippia iniqailina, Prof. Newstead 
has described 3 from Jamaica a coccicl which quite obviously has 
little or no relationship with the genotype of Pseudophillipa, 
and equally obviousty is closely related to the two preceding- 
species. So far as can be ascertained from the figures and the 
somewhat incomplete description of this species, it stands in 
an intermediate position between quinquepori and secretus.
