AbstractThe architecture of the lac cell shows its walls to be impregnated with a skeleton of hard wax fibres. Previously solvents, like alcohol and caustic soda solution, were used to dissolve away the lac resin leaving the waxes intact. It was however difficult to find the waxes in their original position undisturbed. A better method consists in subjecting the object to polarized light which selectively reveals the waxes as conspicuous constituents, whereas lac, being transparent, remains dark. The first stage lac cell has been successfully stuclied in this manner by one of us (Miss Noorun-Nisa Quadri). Here it is proposed to report similar findings extended to the second stage female larva and its cell. For comparison the male of a similar stage has been partly studied as well.
