The larva is twenty-footed ; is larger before than behind, and Is 

 covered with an olive-colored sticky slime. It comes forth in June 

 and September, (found September 15, 1861). It feeds on the upper 

 side of the leaves of the cherry and pear, not eating the veins and 

 skin, and there are usually but one or two on a leaf. Professor Peck 

 and Dr. Harris give the details of these transformations. This some- 

 what resembles S. cethiops of Europe.
