ELEVENTH ANNUAL EEPORT OF 8TATE ENTOMOLOGIST 127 



commonly supposed. An assistant sent to investigate this pest 

 learned many interesting facts concerning it and succeeded in cap- 

 luring some of the flies, a very difficult feat, for they fly so rapidly 

 that the average person never sees them. Specimens sent to the 

 Bureau of Entomology, Washington, D. C, Avere identified as this 

 species. 



The Onion Maggot (Pegorni/a cepuTinrh Bouche). In some 

 Bozeman gardens seedling onions were completely destroyed. Onions 

 grown from sets were also attacked but to a lesser extent. No 

 effective control measures are known. 



{Leiicopis ^riseoJa Fall.). This tin}- Agromyzid fly is of interest 

 as it has been repeatedly observed feeding upon aphids of various 

 kinds. 



COLEOPTEKA 



False Wireworms {Eleodes sp.). Reported for the first time as 

 injurious to grain. A grain grower in the Madison Valley reported 

 that these worms ate the sprouts out of nearly one-third of the fall 

 wheat that was seeded. 



The Currant Fruit Weevil {P send anil lonoinns validus Dietz). 

 A study of this beetle during the past season leads us to believe that 

 it is responsible for nearly one-half of the injury which we had sup- 

 j>osed was done by the currant fly {Epochi-a candensis Loew). 



Granary Weevil {Calandra grcmarja L.). Found in a shipment 

 of flour at Miles City. Seventy-five sacks were infested. This is 

 a notorious pest of stored grain and the knowledge of its presence in 

 Montana should put grain growers on their guard. 



Another Stored Grain Pest (Cartodere mificolUs Alarsh). A 

 number of these small beetles were found in a sample of wheat in 

 Bozeman. 



Spotted Blister Beetle (Epiccnita' macidafa Say). Many 

 reports of injur}^ by this pest were sent in from various parts of the 

 State. Garden crops and potatoes were the principal crops attacked. 



Nuttall's Blister Beetle (Cantharis nuttalU Say). This striking 

 beetle Avas sent in with the report that it was feeding upon alfalfa. 



Colorado Potato Beetle {LcptinofaTsa decemUncata Say). Re- 

 ported as unusually destructive on the Flathead Reservation.
