It is astonish- ing that all of the natural funetions of grasshoppers went on during this remarkal)le period of parasitic attack. Just to what extent the parasitic flies lessened the number of grasshoppers it is difficult to say owing to the prevalence of fungous diseases. Numbers of dying speci- mens were examined, and the vis- cera of those specimens infested with th(> fungus was much more disinte- grated than those attacked l)y mag- gots, yet, as many of the grasshop- piM's were common hosts of disease and maggots, it w;as impossible to ar- rive at any very definite conclusion. Little information could l)e gotten from examination of the dead grass- hoppers in the field as numerous ants soon deprived th(^ hopptn's of viscera or parts of viscera left ])y the maggots. From the puparia of Helicohid hcJlclx two secondary parasites were reared. One of these, ApluBi'rda pallipe^ Say, was Ijred August 3, the other, PcrUaiiij>ux cyaneus Brulle. The young of the locust mite was found to do eft'ective work as parasites upon the wing pads and wings of grasshoppers. Upon the.
