LARVA OF GEACILLAEIA SYRINGELLA. 133 



of the scroll increases. Sometimes, though rarely, the}- 

 are quite irregular. The notching is often clone previously 

 to the rolling, so that a leaf may be found notched down to 

 the petiole, but only lialf rolled. In a very few instances 

 the side edge of the leaf is first begun to be rolled, and the 

 midrib not having to be rolled is not notched. Occasionall}^ 

 the leaf is rolled with its upper surface inwards, beginning 

 at the tip, and in this case the midrib is duly notched. 



When the leaf has been sufficiently rolled, the ends of the 

 roll are neatly fastened together with silk. 



When full fed the larva lets itself down to the ground b}' 

 a silken thread, too often, alas! into the jaAvs of some forag- 

 ing ant, to be carried off as "provisions " to the formicary. 



Besides allowing of the free rolling of the leaves, the 

 "notches" afford strong points of attachment for the silk 

 threads. 



I have since observed the same larvae on " privet," and 

 the midribs of the leaves are notched in the same manner 

 as those of the lilac. 



The insect in all its stages is most admirably described in 

 " Stainton's Natural History of the Tineina."
