(Vitaceae) from Argentina; on Jasminum undulatum (Oleaceze)

Myrtus communis (Myrtaceae) from Dominica; on palms (Palmae)

England; and on Yucca (Spanish bayonet) (Liliaceae) from 
Louisiana. 
As was indicated in the morphological discussion, specimens that 
exhibit considerable differences in the apparent size of the three 
pairs of fully developed pygidial lobes have been placed as this 
species. However, there seems to be complete intergradation in 
this size factor, and no other parallel structural variations that might 
indicate the desirability of further segregation have been noted in the 
specimens studied. The absence of the small dermal pocket outside 
the posterior spiracles, apparently constant in all specimens in which 
the area could be examined adequately, is a characteristic that fully 
distinguishes pergandi from all those forms which have been placed 
in association with it except pittosport. The latter species also lacks 
the pocket, but has conspicuous dorsal intermediate macroducts and 
has a fourth lobe resembling the adjacent plates, although not so 
large as these. 
PARLATORIA PITTOSPORI Maskell

This insect was first described by Maskell (37, p. 77) in 1891, and 
does not seem to have been again recognized in the field, although it 
is included in various lists and catalogs. From specimens from the 
Maskell collection of Coccidae it has been possible to fix definitely 
the characteristics of the species, and material from this collection 
and from other sources has led to the establishment of the synonymy 
detailed below. In the same paper Maskell (37, p. 72) described 
another Australian species under the name myrtus. Specimens from 
the lot so named in his collection, on comparison, prove to be specifi- 
cally identical with those from the prttospori lot. There exists, of | 
course, the possibility that these lots of specimens became confused | 
either during the original installation in the collection or during its 
subsequent handling, and that Maskell actually had two species be- 
fore him, but on the evidence available it 1s necessary to place myrtus 
as a synonym of pittosport. Later, in 189%, Fuller (22, p. 1344) 
listed two new species of Parlatoria from Western Australia, for 
one of which, dryandrae, a slide marked “type” has been av ailable 
for examination. This shde bears only immature stages and in con- | 
sequence is not wholly satisfactory for purposes of comparison. 
Fortunately, it has been supplemented by specimens collected by 
George Compere from the type host, Dryandra, and from the general 
type “locality, Swan River, Western Australia, which aid in con- 
firming the conclusion that P. dr yandrae Fuller is specifically 
identical with P. pittosport Maskell. 
Still later, in 1899, Fuller (23, p. 468) described one more new 
species of Parlatoria, petrophilae, from Western Australia, without 
specific locality, on Hakea. ilicifolia and Petrophila linearis. No
