GREEN. 
Reference :— Green in litt. 
Classification :—Order, HEMIPTERA. Family, Coccidz. Sub-Family, 
Monophlebine: 
Tree attacked :—Mangtfera tndica (Mango). 
Description. 
This insect is very similar in appearance to Monophilebus 
stebbingt, Green (see No. 1 of these notes, pp. 135, 136). The 
females are identical, and Mr. Green states that the males only 
differ in the presence of a very small fourth tassel on each 
side. Fig. 4,d, in Pl. XIX shows the appearance of the 6 of 
this scale, and fig. 6 shows the 9. 
Life Fiistory. 
This scale was first noticed upon the mango trees at the 
beginning of March and disappeared about the middle of May. 
The females (described as large white flat insects) were to be 
seen walk ng about on the ground and crawling up the trees. 
It is probable that they must have been present in the planta- 
tion in January and February, if not earlier, but being then 
small and yellow or brown in colour they were not noticed 
clustered first round the mid-ribs of the leaves and then on 
the young twigs. A careful inspection of the trees at this 
period will probably disclose numbers of the insects, The 
mature females (the white insects) are found clustering round 
the twigs below the fruit where they suck out the sap of the 
twig causing the fruit to fall off. Asin the case of the white 
sil scale, the empty papery skins of the different moults are 
found sticking to the bark of the twigs, etc., fixed to them by 
the sugary secretion excreted by the @ scale. (cf. Pl. XIX, 
fig. 4, €-) 
The winged males are found on the leaves. They are said 
to be present only where the mango trees live in very moist
