Allies. This species belongs to the family of leaf eating beetles,, 

 known as the Chrysomelidae, a group which comprises some of 

 our most serious insect enemies. To it belongs the notorious 

 elm leaf beetle, Galerucella luteola Mull., a species 

 which has destroyed thousands of magnificent shade trees in the 

 Hudson river valley. The two asparagus beetles, Crioceris 

 asparagi Linn, and C. 12-p unctata Linn., are well known 

 enemies to the grower of this succulent vegetable. The familiar 

 yellow and black striped squash bug, Diabrotica vit- 

 t a t a Fabr. is another ally of this destructive grape pest r 

 which is sometimes aided in its deadly work by the steely blue 

 or grapevine flea beetle, Haltica chalybea Illg., a 

 species which has caused great injury in some New York vine- 

 yards during recent years. A number of other related forms 

 nearly as injurious as those named could be easily listed. 

 These destructive allies are mentioned in this connection simply 

 that the grape grower may have some idea of what related 

 species can do, and while this pest may not prove ,so destructive 

 as any of these, it has already demonstrated its ability to cause 

 much mischief. We see no reason at present for thinking that 

 the history of this insect in Ohio may not be duplicated in the 

 Chautauqua grape belt, and perhaps in other sections of the 

 State where this fruit is largely grown. 



Present conditions in Ohio. The destructive work of this serious 

 pest has been known in Ohio for some years. It was first 

 brought to the attention of Professor Webster in 1893. The 

 similarity of conditions existing between the Ohio grape belt 

 and the Chautauqua region led the entomologist to believe that 

 valuable data could be secured by personally investigating the 

 present status of the insect in Ohio. This interesting section 

 was visited about the middle of September and much valuable 

 information secured through the kindly cooperation of Prof. P. 

 J. Parrott, entomologist of the Ohio Agricultural Experiment 

 Station, Prof. A. F. Burgess, chief San Jose scale inspector, and 

 a number of prominent growers. The local knowledge of con- 

 ditions possessed by the two gentlemen named enabled us to
