 cell (Fig. 20-1, c), they change to pupfe of a dccj) 

 (lull yellow color, andlu about three weeks more 

 issue as beetles. These beetles leave the ground 

 from the middle of June to the middle of July, 

 and, so far as we aie aware, do not breed ajrain 

 till the following spring— there being but one 

 In-ood each year. They subsist on the leaves 

 during the fall, but the damage they inllictis 

 trifling compared to (hat whicli they cause in 

 spring. 



Like all other t'lea-bcetlcs, this species has 

 very stout, swollen hind thighs, which, though 



[FiK. ar,.] hidden in our Figure 204, d, are well

 can be destroyed iu great numbers while hid-

 cul are and general cleanliness in a vineyard 

 will, to a great extent, prevent this insect's in-

TUB PALL ARMY WORM. 



From many iiarts of Missouri and Illinois, 

 complaints reach us of the ravages ot the "Fall 

 Army-worm." We have received specimens 

 from Moniteau, Jefferson, St. Louis, Pulaski 

 and Cole counties in Missouri, and accounts of 

 its injuries reach us almost every day from the 

 northeastern portion of the State. "What is this 

 "Fall Army-worm?" will be anxiously asked 

 by the entomological reader; but we doubt 

 whether there is yet any one in this wide world 

 who can tell with any degree of assurance. We 

 can say, that it is a 

 dark worm, the larva 

 of some species of 

 OwletMoth, and very 

 closely allied to the 

 true Army-wm ;m

 this we do not at pic-

 insect has never hern

 transformations. In
