TENTH ANNUAL REPORT 6f STATE ENTOMOLOGIST 57 



The Bumble Flower Beetle ^ liuj)honii iinhi Linn.)- Several 

 specimens of this beetle were sent by persons who reported them to 

 be injuring- apple foliage. They are not to be considered a serious 

 pest. 



The Colorado Potato Beetle {Lcptinotarsa decemlineata Say). 

 During the past year this well known pest extended its Montana 

 range and was everywhere very numerous. Hitherto it had never 

 occurred in abundance in the vicinity of Kalispell ; this year it worked 

 much injury in that district. 



The Pea Weevil {Bruchus pisorum L.). "Buggy" peas taken 

 from seed brought into the Gallatin Valley were shown to the 

 state entomologist last spring and a remedy asked for. Diiections 

 lor carbon bisulphide fumigation were given and a number of 

 bushels were treated. The pea weevil has driven the seed pea indus- 

 try out of many eastern sections of the country and every precaution 

 should be taken to plant seed known to be free from this serious pest. 



Currant Weevil {Anthonomus sp.). While studying the cur- 

 rant fly, a small weevil was discovered attacking currants in much 

 the same manner as the fly. Eggs are laid in the fruit and later 

 hatched into little grubs which feed within the berry, causing it 

 to discolor and eventually drop. 



Grain Weevil (Sp. unknown). Several reports of grain weevil 

 have been received from eastern Montana, but no insects were sent 

 in and lack of funds prevented making a trip to investigate these 

 reports. Should this prove to be the granary weevil of the east, 

 serious trouble may be looked for. 



Alfalfa Weevil (Phytonomus muriims Fab.). Many letters 

 were received from persons who suspected that this notorious pest 

 was already in their fields or who wished information concerning it. 

 So far as known, it does not as yet occur in Montana. 



HYMENOPTERA 



The Rose Slug (Endeloinvra rosae Harris). In Bozeman 

 as well as in other towns, rose bushes were disfigured in early sum- 

 mer by the work of the rose slug. Infested bushes sprayed with 

 arsenate of lead put out new growth and apparently entirely recov- 

 ered while unsprayed bushes remained brown all summer and put 

 out but little new growth.
