25'"* . I December, 



In February Mr. G. S. Saunders found $ scales on Aucuba and 

 a Draccena under glass at Canterbury, and in July I found both sexes 

 abundant, but mostly immature, on tlie under-side of the young 

 leaves of a greenhouse Azalea -. all these on examination exhibit the 

 spinnerets and abdominal appendages of A. nerii, as described and 

 figured by Signoret and Comstock. This species, which is in Walker's 

 British List, is the commonest of the genus, and lives not only on the 

 oleander but a great variety of plants, and in the south of Europe 

 and the United States of America flourishes in the open air. 



Mttilaspis ulicis, Doug. 

 Under this name I previously recorded provisionally (vol. xxii, 

 p. 249) a Mytilaspis living on the spines of furze, and in addition to 

 what was then stated as to the habitat, form and position of the scales, 

 I have now to state that they are shining and not dull brown, and do 

 not become black by age as in M. pomorum ; that the margin is dis- 

 tinctly dentate at intervals ; and the ventral pellicle regularly pitted 

 all over with small circular depressions remains entire, and is not 

 separated up the middle. The spinnerets and abdominal fringe, as in 

 some other species of the genus, are very like those of M. pomorum, 

 yet with a difference, not difficult to see, but not otherwise to be ap- 

 prehended. Taking into consideration all the circumstances pertaining 

 to this form, I certainly believe it to be a distinct species that can 

 easily be recognised by any captor. 



PsErnococcus fagi, Baerensp. 



At the end of May last, at Blackheath, I saw on the trunk of a 

 beech tree, some 40 or 50 years old, many white spots of flocculent 

 matter protruding through small cracks in the dry, black bark, forming 

 mostly isolated, short, stout tufts or streaks, but sometimes several of 

 them were close together, making conspicuous patches. I cut out 

 some of the bark so affected, and found that the flocky matter ex- 

 tended under the free edges of the cracks as it were into the dead or 

 dry bark, and there were in each instance from four to eight fat, 

 yellow, oval Coccids lying close together, but each separately in a kind 

 of cell formed in the compact felt-like cottony flocks. 



On the 16th July I again visited the tree and cut out several of 

 the white patches, and found in each 8 — 12 pale yellow Coccids closely 

 packed together in the felt-like cotton, and surrounded with eggs. 

 Under the microscope I saw the Coccids were just mature. 



They were of sulphur-yellow colour ; in form a short rouuded-oval, barely half 

 a line long, nearly circular, very convex both above and below, and therefore almost
