COLEOPTEEA 



Beet Carrion Beetle {Sil jilia hitHljcrosn I.ee). During' A] )ril and 

 May this pest appeared in destructi\c nnmbers at many i)laces in 

 the sugar beet district around Billings. In some instances young- 

 beets were so badly injured that a very poor stand resulted and 

 in one instance wheat was attacked. 



Lesser Clover Weevil (J'Jn/fojimmi.'^ iii gri rf/sh'js Fa1).). The 

 rirst appearance of this insect in Montana was noted in the _b)cko 

 A'allcv during the past season. This insect closely resemi)les the 

 alfalfa weevil in appearance and the manner of its attack but is nut 

 nearly as destructive. 



Eyed Elater {,llcnisocu]afiif< Linn). A specimen of this strange- 

 appearing insect was sent us from Custer. It is the first one to l>e 

 received into our collection. 



Bumble Flower Beetle (Kiiplioria iiula L.). In the Yellowstone 

 \'alley this beetle was again reported as injuring ctjrn l)y working 

 in the kernels at the tip of the ear. 



False Wireworm (Eleodes e.rfricata var. rojircvim/ lis Idaisdell). 

 False wireworms were very abundant in many localities and in 

 several instances were injurious to newly sprouted grain. 



Cottonwood Leaf Beetle (Liiui scripta Fab.). During July and 

 August this was the insect concerning whicli there was the greatest 

 demand for information. Cottonwood and willow trees were attacked 

 in all |)arts of the Stale. AA'hile this pest seldom kills trees outright, 

 it causes the foliage to turn l:)rown and greatly weakens the ^•itality 

 of the tree. A drawing of the adult beetle ap]:)ears on tlie cover 

 of this pul:)lication. 



Dung Beetle (,l])ha(/iifs iju/jiinafv.^ Abst.). I'or the past two 

 seasons tliis insect has ap])eared in enormous numl)ers and has 

 attracted much attention. In tlie fall on warm, still days the air 

 frequently appears filled with the adults, and horse droppings are 

 com])lelely worked over in a few minutes. 



Wireworms (Ehiteri(hie). Numerous reports of wireworm 

 iiijury were received during the course of the year, including injury 

 to potatoes, corn and grain.
