Cockerell). 
iiin (from drawing by 
margin. Scale very little convex, white, with a more or less pronounced 
grayish yellow tinge. Removed from the bark it leaves a white mark. 
Adult female.— Very broad, oval, bluish green, with the pygidial area 
pale orange and the region about the mouth-parts suffused with van- 
dyke brown. Five groups of ventral glands, caudolaterals of 1G to 17, 
cephalolaterals 9 to 16, median 1 to 4. Lobes pale brown. Three 
pairs of well-formed lobes, two others rudimentary. Median lobes 
well produced, squarely incised on each side, the inner notch not so 
near the end of the lobe 
as the outer. Second lobes 
smaller, notched only on the 
outer side. Third lobes much 
like the second, but also feebly 
notched on the inner side near 
the end. Rudimentary lobes 
pointed. The scale-like plates, 
strongly serrated at their ends, 
are not so long as the median 
lobes, and not longer than the 
second and third. There Is a pair between the median lobes, a pair 
between the first and second, and three between the second and third, 
three also between the third and fourth lobes, and four between the 
fourth and fifth. 
Habitat. — On bark of twigs of an ornamental plant from Japan, 
found by Mr. Alex. Craw in nis quarantine work. 
The species of Parlatoria are not easy to define, and I really do not 
know whether in the present case we have to do with a valid species 
or a variety of theoe. At any rate, viridis may be known by the more 
produced tips of the median lobes, the median plates as long as those 
between the first and second lobes, the bright green color, the five 
groups of ventral glands, and the pale flattened scale. In viridis the 
lateral groups of glands almost or quite touch one another, Avhile in 
thece they are well apart. From Haskell's species, myrtus and 
pittospori, viridis differs at once by the plates being not longer than 
the lobes. From Del Guercio's P. targionii (sub Aspidiotus) it differs 
by the dark exuviffi and other characters. Nor will it agree with the 
other species, pergandei, proteus, zizyphus, and victrix. 
Mytilaspis crawii n. sp. 
Female scale. — Narrow, about 2£ mm. long and one-half mm. wide, 
slightly curved, pale orange yellow, exuviae concolorous. 
Adult female. — Yellow. Four groups of ventral glands, caudolaterals 
of 3, cephalolaterals of 4 in a row. Median lobes very large, rounded at 
ends, their edges finely serrate. They are closely adjacent at a point at 
the base, being separated, however, by a pair of small spine-like plates; 
thence they diverge at nearly a right angle to their rounded ends, thence
