The Imported Currant Worm. 



Nen latus ventricosus. 

 This insect is supposed to have been imported into 

 America from Europe about 1858, since when it has 



spread over a large 

 portion of the United

 coons in which they 

 have hibernated, and 

 deposit rows of small, 

 whitish, glassy eggs 

 on the principal veins 

 of the under sides of
