Reports to the Board of Agriculture. 23, 
attacked by scale, were in some instances perfectly healthy ; in others, 
scale insects (Coccidse) were causing disease. 
The attention of growers is drawn to the normal appearance ot 
bark and rind of the different fruit trees, as it is not an uncommon 
thing to have questions asked regarding the spots present on the 
twigs of various fruit trees and bushes, which are otten, as in the 
present case, mistaken for scale insects. 
The following specimens sent may be taken as examples ol 
this : — 
A. (Apple ; an exceptionally bad case of Quarrenden apple — 
fourth year.) 
This specimen was covered with the Apple-bark Louse or Mussel 
Scale (Mytilaspis pomorum) (Fig. 3, a). 
B. (Bear, presumed to be scale of a different variety, somewhat 
like bark blisters.) 
This twig was quite clean ; the small grey spots (Fig. 3, b) are 
normal bark spots, but might easily be mistaken for the San Jose 
Scale ( Aspidiotus perniciosus ), or the Japanese Fruit Scale (Diaspis 
ctmygdali). 
C. (Gooseberry with scale. This scale in most cases has not 
been noticed to leave a protruded egg trail. Does it ? See E.) 
This specimen contained two specimens of the Brown Currant 
Scale {Lecanium ribis) ; no white protruding egg mass, i.e., no white 
cottony nest is formed so as to protrude from the scale in this species, 
as in the White Woolly Currant Scale ( Piilvinaria ribesii). The 
young scales of this species are much flatter than the old and paler 
in colour. 
D. (Currant with remnants of “ egg trail.”) 
Although no scale is attached to the twig of currant sent it 
contained a large cottony mass of eggs and wool. This resembles the 
cottony cushion seen in Pulvinaria ribesii (vide C). 
This scale can easily be told from L. ribis by being raised up off 
the rind by a pad of white wool. 
E. (Gooseberry with remnant of egg trail, etc.) 
This spray of gooseberry had two mature scales of Lecanium ribis 
and several smaller ones ; also a mass of white wool with no scale 
attached. The scales are the same as C. Possibly the white wool is 
due to the same species as D. 
F. (Apple Branch, grey spots on bark.) 
The grey barnacle-like spots referred to are not scales or anv 
insect, but bark spots. 
G. (Quince, red spots on bark.)
