control of the cotton worm in St. Vincent are the Jack Spaniard 

 {Polistes annularis Linn.), an internal parasite (probably Chalcis 

 annulatus Fabr.), and the fiery ground beetle, Calosoma caldium 

 Fabr. The most beneficial of these insects is, without doubt, 

 the Jack Spaniard, which is predaceous on the larvae or " worm " 

 stage of Alabama argillacea. This insect, which is known in 

 Barbados as the wild bee, is recognised in that island also as 

 a very eflicient enemy of the cotton worm. 



The natural enemies of the cotton worm ^* are sufficiently 

 abundant throughout the West Indies, so that this troublesome 

 pest is, in certain years, held in check to such an extent as to 

 be comparatively insignificant in the damage it does ; on the 

 other hand, in certain years and at certain seasons, it occurs in 

 extreme abundance, the waves of relative abundance and relative 

 scarcity following each other in the manner usual in the case 

 of insects which are controlled by natural enemies.
