EXPERIMENT STATION BULLETINS. 261 



The injury from these little fellows is at times very serious. On May 6th of the 

 past summer, specimens were sent us by Mr. S. H. Fulton, foreman of the South Haven 

 Fruit Station, with the complaint that thoy were eating holes in the leaves of the plants 

 at that place, threatening the crop in the case of some varieties. On October 10th, 

 specimens of what will probably prove to be Scrlodontn pubescens from northern Indi- 

 ana were sent us by Mr. R. M. Kellogg of Three Kivers. This is a closely allied 

 species which works almost the same as the species under consideration. They had 

 constructed small cells of earth and ap])arently were ready for cold weather. Mr. Kel- 

 logg reported that they, together with a root-louse, were killing many plants.

REMEDIES. 



^Yhenever the adult beetle is present and tiie plants are not in bloom, no sets or fruit 

 being present, they may easily be destroyed by a spray of Paris green. Mr. Fulton 

 used three ounces of poison to 40 gallons of Bordeaux as advised, and reports the 

 finding of only two beetles afterward. The result is just as good if water is used 

 instead of Bordeaux, provided lime is added. See directions. When the fruit is set. 

 kerosene-emulsion must be substituted for the Paris green, as the poison is very dan- 

 gerous when applied to a fruit which ripens as quickly as the strawberry. It is almost 

 certain that the use of commercial fertilizers or tobacco dust would prove useful. 

 Of course it would be folly to use infested ground for the purpose of setting out new 

 plants. Wait until the insects are starved out and do not grow strawberries very near 

 the old infested patch. 



For the larvae of the iScclodoufa pithcscens, late fall plowing or early spring plowing 

 will bury many of them so deeply that they \A'ill never come out. 



THE BUMBLE FLOWER BEETLE. 



(Euphoria inda.) 



During the first warm, sunny days of spring, it is not uncommon to see numbers 

 of clumsy beetles flying swiftly about in circles over a clear space of grass or lawn. 

 The flight is rapid and accom])anied by a loud humming noisc^ot unlike that of a 

 bumble-bee. Often, if closely watched, it will be found that one is chased bj' a fly a 

 little larger than a house fly. (A species of Tachinid which is parasitic, and which is
