also on rice and on grasses. Phenacoccus insolitus, Gr., has been found 
abundantly upon barlar ( Sidacordi - 
folia). Antonina indica, Green (fig.

quite separate from the body ; it is 
found on grasses. 
The Tachardiince include the lac 
insects, of which Tachardia lacca, 
Kerr. (Plate LXXXIII), is the most 
important, T. fid, Gr., and T. albizzice, 
Gr., also yielding lac on a commercial 
scale. It is by no means clear which 
lac is really T. lacca or how many 
species there really are. There is a 
considerable mass of literature ey die

LXXXII, fig. 1 ); Ceroplastes is covered in solid wax, usually arranged 
in plates. Lecanium hemisphcericum, T. T., is the brown scale of coffee, 
L. viride, Gr., is the green scale of coffee. The former is common on guava 
in other parts of India. L. hesperidum, Linn., is the soft scale, found in 
the leaf-nests of the red tree-ant (Occophylla smaragdina). L. nigrum, 
Nietn., is found on cotton, hibiscus, etc. Pulvinaria psidii, Mask.
