SOME SCALE-INSECTS (COCCIDA) FOUND IN THE 
ISLE OF MAN. 
By Proressor R. NEWSTEAD, F.R.S. 
Thanks to Professor Herdman’s kind hospitality I was 
able to devote some attention to the Coccid fauna of the Isle 
of Man, during a short stay at Port Erin, in September, 1918. 
As no attention had hitherto been given to the subject, I 
naturally expected that interesting records awaited discovery. 
In this I was not disappointed; but further search would 
inevitably bring additional records, more especially so of 
those species which live upon deciduous trees and shrubs, 
such as the Diaspine and the genus Lecanium. The publication 
of the following notes of my captures may be of value to those 
who take an interest in the insular fauna :— 
Newsteadia floccosa (De Geer). 
Several examples of this species were found in moss and 
decayed vegetable matter surrounding the stems of heather, 
in a sheltered spot near the Calf Sound. In some of the examples 
the so-called “ marsupium”’ was fully developed; in others 
the waxen lamelle forming this structure were quite rudimen- 
tary. 
Orthexola vejdovskyi, Sulc. 
A single female of this rare and interesting coccid was 
found in association with the preceding species. O. veydouskyi 
forms the type of the genus, and was discovered by Dr. Sule 
at Prague, Bohemia, in 1894. Mr. E. E. Green has recorded 
it from a single locality in Great Britain; and I also found it 
in moss on the clifis at the Isle of Wight in August, 1905. 
Eriococcus green, Newst. 
Two females. The ovisacs of both examples were attached 
to fragments of rock, lying partly buried in coarse grass, at
