Figures obtained this year seem to indicate that the actual losssustained by a cotton crop from Platyedra during the season picking is \ of theboll infestation and during the kar picking \. 2. Earias is a much less important pest although one larva does moredamage than one Platyedra larva. 3. Loss due to Earias may be roughly estimated at \ the bollinfestation. 4. Examination of entire crop from a field about 4 acres showed theloss due to Pink Boll-worm to be 11 per cent, and Earias spp. 3 percent. PLATE XVIII. y=t,< ffS o .
