The follow- ing list includes the more important members of this group:. Fig. 18.âCalosovia calidum: beetle and larva (from Riley). Metapod'ms femoratus Fab. (PI. XVIII, fig. 5). Sinea diadema Fab.

In addition to the aforementioned enemies, the "devil's horse" {Stagmoiiumtis Carolina Burm.) may be mentioned as an activel}' pre- daceous insect frequenting the fields. Among the vertebrate enemies, the common toad {Bufo lentiginosus and B. valiceps) stands out as rather important. Although feeding upon almost any living insects which it can capture, sometimes at least boll worms form a considerable portion of its diet. On September 14, 1904, Mr. C. R. Jones collected at German- town, Ark., a number of toads from a field of late cotton badly infested by the bollworm. The toads in the field at that time were exceed- ' z ingflv numerous, and nine were sent in for ^^^- ^^â â'Podi%usjiyinoms: ,. .11 /. n - adult, egg, and nymphs dissection, with the following results: (fromRiiey)..
