OCCURRED E OF SPECIES.

Waco Tex. Although a large quantity of these squares were exam- 

 ined no specimens of this species were obtained except From the 

 e ' ral breeding cage. The species is known as a parasite of an 

 activating weevil {Ardhmmm si&nMus Say), and il is possible that 

 in the fall the parasites may attack Anthonomus gramdia. 



GEOGRAPHICAL AND SEASONAL DISTRIBUTION OF PARASITES. 



Only four of these parasites are at presenl of any greal importance. 

 ln arranging the percentages of each species with regard to the total 

 number of parasites the following table (Tabic XIX) has broughl 

 out sufficient data, for the production of a map (fig. 6) winch shows 

 the area over which any two of them are predominant. Thus, over 

 the entire western half of the area studied Bracon meUitor andOrto- 

 ,,„,.„* incertus arc the most active, while in the Northeast and East 

 OerambycoUus cyaniceps shares the importance with the otnertnree 

 in more or less limited belts:
