26 TETTIGID.-E OF NORTH AMERICA 



it over and biting it savagely about the nect:. The little 

 locust finally escaped by a vigorous jump. 



According to P. R. Uhler (1884) Galgiilus oculatus, an 

 hemipteran insect, is a serious enemy. They may often be 

 seen, says Uhler, "in the month of May walking about 

 between stones on the low banks of brooks and streams, 

 where Tcttix and Batracliidca* abound, watching an oppor- 

 tunity to seize one of these insects, and when the favorable 

 moment arrives, leaping suddenly upon one of them, clasping 

 it with tight embrace between the front femora and tibia and 

 there sucking out its vital juices." In a marshy meadow in 

 May the writer suspected, from seeing a number of common 

 toads jumping about on the ground where Tettigids were also 

 quite numerous, that they might form the food of the batrachi- 

 ans. The stomach of one of the adult toads there taken, on 

 subsequent examination, was found to contain a crab spider, 

 some beetles, Tet tig idea parvipcimis, Tcttix oriiatits, with 

 material too macerated to identify. The Tettigids were partly 

 digested, but the remaining pronotum was sufficiently preserved 

 in each species to furnish a certain clue. Professor S. A. 

 Forbes (1888), in his researches on the food of fresh water 

 fishes, found that these acridians were eaten by fishes. Icta- 

 luriis punctatus had eaten Tcttigidca in June, Hyodoii tcrgisus 

 had fed on Tcttix in October, and it is related of Lcpoiiiis 

 pallidiis that it had devoured Tcttigidca in June and Novem- 

 ber. The robin also is said to feed quite freely on these 

 orthoptera. As the Tettigids commence to multiply in the 

 spring and early summer we find numerous frogs, toads, and 

 snakes living in the same environment, that doubtless find 

 them within easy reach and prey upon them. These enemies 

 are probably but a small part of those Tettigians have to con- 

 tend against.
