inost of them about three. It is true that we are not 

 personally cognizant of the fact, that these holes are 

 bored by the same Joint- worm Fly, that escapes from 

 similar holes in such profuse abundance in the following 

 June; but Prof. Oabell, of Virginia, stated to Dr. Harris 

 with reference to the wheat-inhabiting Joint-worm, that 

 he had known a few flies to leave the straw the first year, 

 but in each instance the fly which came forth thus was 

 the true Joint- worm Fly. As already shown, the flies 

 that emerged from these Canada galls in the succeeding 

 summer, came out from June 9th to June 16th and sub- 

 sequently. (American Entomologist. )

 the Forest (Clisiocampa sylvatica, Harr.), described 

 under FRUIT TREES. 



In some of the Southern States, the Cotton Worm 

 (Aletia argillacea, Hubn.), is called " Army Worm," and 

 more frequently the " Cotton Army Worm," an insect 

 most exhaustively treated of by Prof. Riley in Bulletin 

 No. 3, of the U. S. Entomological Commission. 



Still another insect, common in the Southern States, 

 (LapJirygma frugiperda, Sm. and Abb.), which some- 

 times attacks cotton, has been called " Army Worm." 

 Its proper name is " Southern Grass Worm," and it pre- 

 fers grasses and weeds to cotton and other crops. To 

 distinguish the true Army Worm from all others to which 

 the name has been given, it may be called:
