Aleyrodes sp. An unidentified species has been found on mango 
but is not known as a pest. 
Monophlebus stebbingi var. octocaudatus occurs every year at Pusa 
from January to May and attacks all fruit trees, massing on the young 
shoots. It is not a special pest of mango but may sometimes be a pest 
of this tree when it is in numbers. The eggs are laid in the ground 
about May and remain there until they hatch out about November- 
December. Digging around the trees to destroy the eggs and banding 
the trees when sufficiently valuable, to prevent the young bugs from 
crawling up, will reduce damage. A layer of fine sand around the tree 
makes an effectual barrier so long as its surface remains dry and loose. 
Icerya seychellarum has been recorded on mango at Poona but is 
not common and not known as a pest of mango. 
Icerya minor [Entomological Memoirs, II, 17-18] is found on mango

Pseudococeus (Dactylopius) sp. occurs in Madras but is not serious

Pulvinaria psidii [“ South Indian Insects,” p. 511, fig. 399] occurs

Coccus (Lecanium) mangifere has been found on mango at Pusa, but 
not as a pest. 
Chionaspis dilatata has been recorded on mango at Poona ; it is of 
common occurrence on both surfaces of the leaves. Also found on 
palms at Calcutta. 
Chionaspis vitis is said to be a bad pest of mango in Madras, but 
we know little about it. 
Leucaspis indica has been recorded from Poona as occurring com- 
monly on mango trees. “ The scales are completely hidden under the
