COCCIDM AND ALEYRODID. 173 
variolosum in the lower portion of the same wood mentioned 
above, I had the good fortune to find a few specimens of this 
insect, thereby extending its range very considerably. 
Physokermes abietis (Geoff.).—I have previously searched for 
this insect for several years without success. This year, when 
once I had discovered how it feeds, I have found it almost 
everywhere on spruce. Yorks: Marton, Ayton, Nunthorpe. 
Durham: Wolsingham in an isolated spruce wood at over 
1000 ft. Northumberland: Haydon Bridge and up the West 
Allen as far as Whitfield, not ascending further in spite of the 
number of suitable woods. 
Dactylopius hibernicus (Newst.).—Sparingly in the saltmarsh 
at Greatham in Easter week. 
Eriococcus devoniensis (Green).—Found not incor only 
wherever deliberately searched for on Erica tetralix on the 
Cleveland Moors. 
Fonscolombia fraxini (Kalt.).—In abundance on a single 
isolated ash in a field a few miles from Middlesbrough and in 
a wood near Nunthorpe; is quite common, although local, in 
S.E. Durham. 
Ortheziola vejdovskyi (Sule.).—BeforeI knew about this species 
I had taken it, and had referred to it in my list of ‘‘ Coccide of 
North Yorks and Durham” as a new species. It occurs both in 
Durbam and in Cleveland. I got it in Durham, near Lamesley, 
on oak roots exposed by overturning a huge boulder when I was 
in search of spiders and other arachnids. In Cleveland I got it 
on Great Ayton Moor; under what circumstances I cannot at 
present recall. 
Orthezia cataphracta (Shaw).—Practically everywhere in all 
three districts ascending to the highest points examined, but not 
yet found at sea level. Prefers Sphagnum and Polytrichum, but 
almost as common in dead leaves, bases of rushes, grass, etc. 
Orthezia urtice (L.).—I discovered this insect in immense 
quantities in Greatham Saltmarsh, in Durham, in September. 
It occurred in alJl stages on thrift (Armeria maritima), sea 
lavender (Statice limonium), and grass in places covered by the 
sea at high tide; not seen elsewhere. [Since writing this I have 
found the curious winged male in swarms on various plants in 
the marsh ; it is only to be found for a few days.] 
Newsteadia floccosa (De Geer).—Almost as abundant and in 
the same places as Orthezta cataphracta, but apparently preferring 
the drier spots I find it on heather on Eston Moor (Yorks). In 
Durham, on what fifty years ago was Beamish Moor, although 
heather, Sphagnum, Polytrichum are practically gone and the moor 
almost a mere name. I find it on honeysuckle roots, for honey- 
suckle appears to be invading the uncultivated parts, and, with 
the sycamore, has obtained a firm hold.
